Primary intraosseous squamous cell carcinoma (PIOC) of the mouth is a very rare but well-known carcinoma. It is locally invasive and its prognosis is quite poor. It may originate from the walls of an odontogenic cyst or de novo from the remnant epithelium at this region. Because the early symptoms of such malignancies are sometimes similar to those of inflammatory or periodontal diseases, early diagnosis is the most important step toward appropriate treatment.

The case was a 46-year-old female with a sudden luxation of two posterior mandibular molars referred to a general dentist in May 2019. With diagnosis of periodontitis, the teeth were extracted without finding the cause of the tooth luxation. After four months, because of pain, swelling and non-healing socket of extracted teeth she referred to the department of Oral medicine in Mashhad Faculty of Dentistry. The patient was healthy with no systemic disease, drug history or familial history of cancer and no history of trauma, habits, tobacco, alcohol, and smoking. ln clinical examination, a nodular swelling with extensive ulcer and rolled borders along with hyperkeratosis and erythema on the posterior part of the right mandibular ridge was observed. The Extraoral examination revealed a tender mobile lymph node in the right submandibular region. After radiographic evaluation, with an initial diagnosis of SCC originated from the socket of extracted mandibular molars, incisional biopsy was performed, and histopathological analysis of the specimen revealed a primary intraosseous squamous cell carcinoma (grade II) and then necessary treatments (surgery, radiotherapy, chemotherapy) were performed.

Dentists should know that any sudden changes in the mouth or teeth such as tooth luxation should be considered as a possible sign of malignancy. With proper diagnosis and early initiation of treatment, the prognosis of the disease can be improved and the patient can be treated with minimal complications of necessary treatments of surgery, radiotherapy, or chemotherapy.

Malignant lymphoma of the oral region is uncommon and accounts for approximately 3.5% of all oral malignancies. Non-Hodgkin’s lymphoma occurs primarily in adults, although children may also be affected, particularly by the more aggressive intermediate and high-grade forms. The condition most commonly develops in the lymph nodes, but so-called extra nodal lymphoma is also found. In children, extanodal lymphoma is more common. The presentation can be as a non tender mass mostly in cervical, auxiliary, or inguinal regions that has been enlarging for months. In the oral cavity, lymphoma appears usually as extra nodal disease. The malignancy may develop in the oral soft tissues or centrally within the jaws. Soft tissue lesions appear as non-tender, diffuse swelling; they most commonly affect the buccal vestibule, posterior hard palate, or gingiva. The patient may complain of paresthesia, particularly with a mandibular lesion (numb chin syndrome). Case report: An 8-year-old boy was visited in the Oral Medicine Department of Mashhad Dental School with the chief complaint of permanent tooth mobility in the oral cavity for 15 days. The patient also had a history of bone pain mainly in lower lip for the last month and Bell’s palsy (left side) was observed which had been occurred since 7 days before. Simultaneously, the patient had malaise, anorexia, bone pain, illness, lymphadenopathy (head and neck), and flu like signs and symptoms, fatigue and leukocytosis. Under clinical diagnosis of lymphoma, the patient was referred to pediatric hematologist-oncologist. Our diagnosis, none Hodgkin’s lymphoma (NHL), was confirmed by the report of lymph node biopsy.

Dentists can play an important role in the early detection of the malignant lymphoma of the oral cavity. NHL primarily appears in the head and neck. It is typically characterized by a swollen, non-painful lymph node although other presentations may pose significant diagnostic problems and frequently lead to misdiagnosis and mistreatment.
