To explore the diagnostic value of digital 320-slice volume computed tomography (CT) scanning in gastrointestinal lipoma.

The clinical data and CT features of 21 gastrointestinal lipoma cases confirmed by pathology were analyzed retrospectively. The tumor location, size, density, and clinical manifestations were summarized.

Among 21 patients, nine, four, three, and three cases occurred in the duodenum, descending colon, stomach, and ascending colon, respectively; one case each occurred in the jejunum and sigmoid colon. Tumors located in the duodenum were asymptomatic, while those located in the colon presented with abdominal pain and diarrhea. CT images demonstrated round, oval, and short intestinal fat-like density masses in the gastrointestinal tract with varying sizes. The CT value was in the range of -80 to -120 HU. Routine enhanced scans revealed no enhancements. Three cases were accompanied by intussusception. Pathological examination showed prominent fibrovascular septa.

Digital 320-slice volume CT scans have advantages over other modalities in the diagnosis of gastrointestinal lipoma and may help evaluate the tumor and surrounding tissues, supporting clinical practice.

Lipomas of the of the head and neck region are rare, more so in the retropharyngeal space. Lipomas in this region can produce symptoms that demand surgical excision. This paper describes a case of lipomatous hamartoma of the retropharynx, which to the best of our knowledge has not yet been reported in English literature.

 Case Report:

 A 53-year-old gentleman presented to the ENT department with snoring, voice change and stridor. Examination revealed a smooth bulge in the posterior wall of the oropharynx causing near complete obstruction of the airway. A contrast enhanced computed tomogram revealed a non-enhancing hypodense lesion in the retropharyngeal space extending from C1-C4 level, which was suggestive of a lipoma. The tumour was surgically excised trans-orally. A limited review of literature is also presented. 

Trans-oral approach is preferred to external approach for surgical removal of benign retropharyngeal tumours that cause obstructive symptoms, as our case. This approach is safe, effective, and associated with lesser post-operative morbidity.

Lipoma is an uncommon mesenchymal tumor of the colon. They are typically symptom free, the large lipomas within the colon are rare, and can cause obstruction, bleeding, or intussusception. Intussusception is comparatively common in pediatrics and in adults, it could be a rare entity. Pathologic lesions are usually found with a major percentage of malignancy. This is a retrospective evaluation of an adult with an intestinal intussusception who underwent oncosurgical treatment. He was diagnosed with surgically proven intussusception. Using ultrasound and colonoscopy as diagnostic studies, colocolic intussusception was discovered. The patient underwent oncosurgical exploration. Intestinal resection with abrupt anastomosis was the procedure of choice for the patient. The etiology was benign lipoma. Adult intussusception should be evaluated in any patient with subacute abdominal discomfort with bearing in mind the high rate of malignancy and a lower rate of benign tumors. intestinal resection without reducing is highly recommended for colonic intussusceptions.

Intracranial lipomas account for less than 1% of all brain tumors. Corpus callosum lipoma (CCL) is a rare finding and up until now, documented cases are around 200 patients. These lipomas remain mostly asymptomatic, but when symptoms appear, they present through headache, seizure, dementia and in some cases, rather uncommon neurological disorders such as mirror writing.Fourteen years old girl with history of 8 years headache and recent development of vertigo, extremities trembling and drop attack was referred to neurologist and brain imaging confirmed CCL.Herein, we report another rare case of CCL, with common and uncommon symptoms of latter tumor in detail; in addition to reviewing the previous 80 years case reports aiming to achieve comprehensive perception from CCL

Soft tissue lipoma is one of the most common benign tumors rarely forming in hand. In this study, 11 cases of symptomatic hand lipoma were investigated. The chief complaint was a palpable mass in all 11 patients, out of whom 6 (55%) cases presented with neurological symptoms, including paresthesia and numbness in the median, ulnar, and superficial radial nerve pathways. One patient had an intramuscularly painful forearm with a large mass presentation. In the finger, the clinical manifestations were radial anesthesia of the finger. The mass sizes were above 5 cm3 and less than 5 cm3 in seven and four patients, respectively. The mean follow-up period was 25 months. No patient demonstrated a recurrence during the follow-up period. Although lipoma is a benign tumor and often presents itself as a palpable mass in the hand, it can cause neurological symptoms and decreased function. Regardless of the size of the tumor, mass removal can prevent symptomsLevel of evidence: IV

We report the case of a 14-year-old girl with huge cervical intramedullary lipoma, who presented with spastic quadriparesis. Her MRI revealed an intramedullary lipoma extending from the craniovertebral junction to the sixth cervical vertebra. There was no spinal dysraphism. Subtotal excision of tumor with primary dural closure and laminoplasty was performed from C3 to C6, which produced an improvement in the patient’s function.

Sub-epithelial lesions (SELs) discovered during endoscopy may be originated from either layers of the gastrointestinal (GI) tract or outside of the GI lumen. Endoscopic ultrasonography (EUS) is used to identify the source of these lesions and occasionally to obtain a sample.

In this study, we aimed to obtain the prevalence of upper GI SELs along with their ultrasound and pathological features.

In this cross-sectional study, all patients referred to a referral endoscopy department for EUS were enrolled. Size and location of lesions, relevant layer, endosonographic and endoscopic features of the lesions, and definitive pathological diagnoses were collected.

A total of 305 cases were evaluated. 76.32% of SELs had a homogenous echo pattern. The lesions were predominantly seen in the antrum. The lesions were originated from submucosa (37.38%), muscularis propria (33.77%), and deep mucosa (28.85%), respectively. Gastrointestinal stromal tumors (GISTs) (47.54%) were the most common type of SELs. The most prevalent heteroechoic and hyperechoic lesions were pancreatic rest and lipoma (55.8%), respectively.

Most SELs are located in the gastric antrum. Out of all evaluated lesions, GISTs were the most frequent lesion discerned by EUS.

Lipoma a benign mesenchymal tumor is a rare finding in the oral cavity. This paper reports a case of 75 years old male patient with a huge lipoma of the floor of the mouth, along with its manage- ment at the Department of Maxillofacial surgery at Abbasi Shaheed Hospital, Karachi Pakistan.

Lipoma of the floor of the mouth is very rare. We endorse complete surgical excision as an optimal treatment of oral lipoma.

The lipoma is one of the benign soft tissue tumors that occur most in adulthood. These tumors are one of the common tumors of the limbs, and rarely occur in the abdominal cavity. These masses usually grow slowly and are asymptomatic.

In this article, we present a 23-year-old woman who was referred to a doctor with complaints of abdominal pain and enlargement that occurred in the last 4 months. Following surgery and sampling, it was found that the patient had a lipoma, and the liver was a phlegmatic liver in the liver form.

The recurrence and metastasis of the primary tumor histology are not always predictable, and the authors stated that all cases of individual fibrous tumors should be known as potentially malignant.

Lipomas are the most common benign tumors of connective tissue which can be found in different parts of the human body. In rare cases, their size may be so giant which could be an indication for surgery. Here, we present a case of congenital multiple asymmetrical giant lipomas of the back in a young female. She presented with a chief complaint of physical discomfort due to the giant size and weight of the lipomas. Apart from that, she was in total health. She was born with 5 small lipomas in the back and flank region which had become giant lipomas with estimated weigh around 16 kg in total by the age of 24. The patient underwent seven operations to remove or debulk the mass over a 24-year period since the recurrence of the growths was inevitable.Considering the size of the mass and differential diagnosis, such as liposarcoma, and since no risk factor or underlying etiology was detected for the patient`s condition, surgical excision was the preferred technique for this case.

Lipoma is a rare benign tumor that overgrows in oral cavity. Its occurrence rate is about 1-4% with predilection for males rather than females. Lipoma is associated with adipose tissue and is usually seen in major salivary glands, buccal mucosa, and vestibule. Fifty percent of lesions are seen in buccal mucosa. The progressive and aggressive growth of these lesions may interfere with speech and mastication owing to the dimensions and location of the tumor. The lesion basically affects the individuals of 4th to 5th decades. Lipoma is managed by surgical excision using scalpel, laser, or electro-cautery.

This study presents two 63 and 18 years old male patients with lipoma in their buccal mucosa along with their improved situation following the treatment. The treatment included surgical excision of the lesion and suturing the surgical area.

The incidence of intraoral lipoma is low and buccal mucosa is the most common region for the occurrence of oral lipoma. Most clinicians suggested surgical techniques as a certain treatment

Adipocytic tumors and its variants are common neoplasms of adults; however, they are rarely seen in paediatric age group, too.  Lipoblastoma typically occurs in children and are diagnosed by the presence of a multivacuolated lipoblast. However, things get complicated when one has to search for these lipoblasts in a background of classical lipoma. As a result, such cases are misdiagnosed and managed inappropriately. We report the first case of a congenital lipoma like lipoblastoma with an unusual presentation.

A 10-day-old male was admitted to the Paediatric Surgery Outpatient Department with a mass in his perianal region since birth. On examination, the mass was non-tender, pedunculated, and located at the margin of the anal opening. A provisional clinical diagnosis of anal tag was made, and swelling was excised. Grossly, we received a skin covered soft tissue mass measuring 1.2cm in diameter. The cut section was yellow and had a soft to firm consistency. Histopathological examination showed a well-delineated moderately cellular lesion comprising of lobules of adipocytes in varying stages of maturation; large number of mature adipocytes and few interspersed multivacuolated lipoblasts. A final diagnosis of lipoma-like lipoblastoma was made. 

Lipoma-like lipoblastoma can be seen as a congenital mass and at unusual sites like the perianal region. An accurate diagnosis of this entity is essential for appropriate management. Histopathology is the gold standard for diagnosis and calls for increased awareness.

Lipomas are the most common benign neoplasms, occurring in any part of the body where fat is present. Their occurrence in the head and neck is not common. Here, we report a large laryngeal lipoma with extra laryngeal component, mimicking mixed form of laryngocele.

A 47-year-old man presented with a 3-year history of hoarseness, intermittent dyspnea and mass sensation in the neck. The patient was submitted to indirect laryngoscopy; a large submucosal mass obliterating the left side of the supraglottic larynx and partially obstructing the airway was found. Enhanced computed tomography (CT) scan demonstrated non-enhancing homogeneous hypodense fat density mass lesion measured 55*45*32 mm, extending through the thyroid membrane to parapharyngeal space and showing extra laryngeal component with an intact laryngeal mucosa lesion. Open surgery of the submucosal mass was performed. Pathology examination confirmed the diagnosis of lipoma.

Neck lipomas are also typically asymptomatic, but can compress nearby structures, causing symptoms such as hoarseness, dyspnea and dysphagia. When symptomatic, they should be removed via surgery.

The lipoma is 5% of benign tumors and 25 to 50% of soft tissue tumors. It most occurs in the upper trunk area, neck and the extremities. But it is rare in the oral and maxillofacial area. It is a benign lesion composed of fat mature adipose tissue that Separated with fibrous septa and surrounded with a thin fibrous capsule. Jaw Intraosseous lipoma is very rare, and its prevalence has been mentioned in articles 1.0%. The case of this manuscript was a 33-year-old woman who referred to an orthodontic specialist with a complaint about the tooth crowding and requesting orthodontic treatment. Based on clinical, radiography and histopathology finding, a diagnosis of intraosseous lipoma of the mandible was made.

Tethered spinal cord is the most common anatomic deformity which is usually diagnosed in childhood. This study aimed to describe the different anatomo-radiological patterns of the tethered spinal cord with lipoma. Methods and Materials/Patients: We conducted a retrospective and descriptive study in Neurosurgery Department of General Grand Yoff Hospital and the Neurosurgical Clinic at Fann University Hospital of Dakar, Senegal. Eight patients with spinal cord lipoma underwent surgery in these medical centers from July 2007 to January 2011. Anatomo-radiological and clinical data of the patients were collected and analyzed. The mean age of the patients was 4 years ranging from 45 days to 30 years. Male to female ratio was 0.6. The symptomatic triad of median cutaneous signs, orthopedic, and sphincter disorders was found in 2 (25%) patients. Neuroimaging, mainly MRI, showed conus medullaris lipoma in 7 (87.5%) cases, and a filum terminalis lipoma in 1 (12.5%) case. All patients had a tethered spinal cord with a low-lying conus medullaris. The dehiscence of posterior lumbosacral and sacral vertebral arches was noted in 7 (87.5%) cases and scoliosis and scalloping each in 1 case. All patients were operated and the outcome was good for 5 (62.5%) patients. No death has been reported. According to surgical findings, the patients were grouped in the modified Chapman’s classification. In comparison to myelomeningocele, tethered spinal cord with lipoma is a rare condition. Health practitioners should be aware of this condition when facing a child or a young adult patient bearing a median lumbar sacral cutaneous stigmata associated with or without lower limb orthopedic abnormalities and or sphincter disorders. Ultrasound and MRI are good diagnostic tools for the newborn allowing to make good surgical planning. However, MRI is reportedly more sensitive and the surgical option for asymptomatic cases has remained controversial. To our experience, the surgical findings can provide comprehensive information on the interface between the lipoma and the neural structure.

Giant lipomas are benign soft tissue tumors found rarely in the neck and are still rarer in the anterior part of the neck. A 70-year-old male patient was presented with a huge swelling measuring 35 cm in maximum dimension, in the front of the neck, reaching up till the umbilicus. The swelling was painless, slow growing and acquired the huge size in approximately 20 years. Ultrasound and CT scan findings were suggestive of a soft tissue lesion. Fine needle aspiration cytology yielded mature adipose tissue fragments. A complete surgical removal of the mass was done which on gross examination, measured 32 cms in longest diameter and weighed 2500 grams. Diagnosis of giant anterior neck lipoma with pressure ulcer was confirmed on histopathology. We described a case of excessively large lipoma of anterior neck, which is the largest anterior neck lipoma with pressure ulcer reported till date.

Cardiac lipomas are extremely rare tumors of the heart. They are usually symptomatic and rarely may be found incidentally in autopsies. Here we describe a 23-year-old healthy man, in whose physical examination for employment a murmur was found incidentally. Transthoracic and then transesophageal echocardiographic examination showed a 4-cm oval-shaped mass in the right ventricular outflow tract. He underwent elective surgery, during which the tumor was removed under cardiopulmonary bypass and aortic-cross clamping via right atriotomy. The postoperative course was uneventful, and the patient was in good condition at 1 year’s follow-up.

Epidemiologic data of upper extremity tumors are still few and sometimes conflicting. In our department, hand surgeons manage these tumors. Good documentation of patients’ information permitted us to make an epidemiologic study on the tumors of the upper extremity operated in our department.
We retrospectively studied all the cases of upper extremity tumors operated from 1992 to 2012. The required files were collected from the hospital’s databank and the pathology report from the registry of the department of histology.
The mean age of patients was 37.91 years (from 3 to 83 years). The series included 100 patients (60 women and 40 men). Tumors concerned soft tissues in 78 cases (78%), bone in 18 cases (18%), and skin in 4 cases. Nearly all the malignant hand tumors were found in men (5 males, one female).
The data are comparable to other published studies. Upper extremity tumors are more prevalent in females (60%). The prevalence of bone tumors (18%) in our study is greater than other studies (from 1.6% to 11.4%) and the prevalence of skin tumors is lower (4%). Except for skin tumors where recruitment modalities are more variable, this series seems to be a good reflection of the prevalence of the different types of hand and wrist tumors.
