Synchronized evidence of bilateral ovarian masses with an asymptomatic  incidental appendiceal solitary mass is an unusual  event during  operation.  The main differential diagnosis in this status  is metastatic mucinous adenocarcinoma of ovary to appendix  versus  metastatic mucinous neoplasm of appendix  in both side ovaries. Herein, i present a  metastatic bilateral ovarian high grade serous carcinoma to the appendix as  a diagnosis pitfall. A 43-year-old woman, with menstrual irregularity was referred. Imaging studies  showed bilateral ovarian masses. She underwent total abdominal hysterectomy, bilateral salpingo oophorectomy , omentectomy,  pelvic lymph nodes dissection and appendectomy.  Final diagnosis, according to histopathological and immunohistochemical findings was metastatic bilateral ovarian high grade serous carcinoma of the appendix. These tumor markers may be useful for final diagnosis because tumoral tissue expression of them is not 100%. Therefore usage of several of them in correlation with histopathology findings, definitely helpful.

Primary carcinoma of the fallopian tube is a rare, but fatal gynecologic cancer. The preoperative diagnosis of this carcinoma is challenging due to the absence of specific symptoms and signs, and in most patients, it is an intraoperative finding. A 55-year-old patient (G3Ab1P2) was referred to the urogynecology clinic of our hospital with the chief complaints of heavy, prolonged menstrual bleeding and a persistently abnormal yellow discharge, which could not be distinguished by the patient from urinary leaks. After a complete diagnostic work-up, the patient was identified as a candidate for hysterectomy due to abnormal vaginal bleeding resistant to megestrol acetate, family history of malignancy, and abnormal vaginal discharge. Laparotomy revealed unusual left fallopian tube features (large, bulky, and vegetative), suggesting malignancy. The intraoperative frozen-section analysis of the left fallopian tube and the ovarian specimens indicated the mass as a high-grade serous carcinoma of the fallopian tube. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy were performed for the patient. The definitive histopathological diagnosis was high-grade serous carcinoma of the left fallopian tube (stage 2b) with omental involvement, without any evidence of lymphovascular invasion. High-grade serous carcinoma of the fallopian tube is likely to have non-specific symptoms, causing a significant delay in diagnosis and treatment, which negatively affects the prognosis and survival of these patients.

Serous cystic neoplasms of the pancreas account for 10% to 16% of all pancreatic cystic masses. Serous cystic neoplasms were evaluated as benign pancreatic masses. For all that, the first serous cystic neoplasm with malignancy criteria was described by George in 1989. Only 10 cases have been observed until today. A 53-year-old female patient presented with complaints of jaundice and abdominal pain. Her past medical history revealed pancreatic cysts during the examination for abdominal pain. Computed tomography revealed a cystic mass of approximately 8 cm in size with a solid component originating from the head of the pancreas and leading to obstruction in the bile duct. She underwent pylorus-preserving pancreaticoduodenectomy and was discharged on Day 12 due to the absence of any surgical abnormality during the postoperative follow-up. On examination of the surgical specimens, a multiloculated cystic tumor with a serous content was detected. Tumor metastasis which demonstrated a positive reaction with cytokeratin 7 and cytokeratin 19 in the celiac lymph node biopsies was detected. The tumor was found to have a histomorphologically benign appearance and was reported as a serous cystadenocarcinoma based on the desmoplastic stroma and lymph node metastasis. Cystic neoplasms of the pancreas can be followed conservatively. Malignant transformation in pancreatic serous cystadenocarcinoma should be kept in minds such as pancreatitis, bile duct obstruction, and new-onset or increased complaints during follow-up.
