We report three cases of squamous cell carcinoma originating from ovarian dermoid cysts. All patients were postmenopausal with the chief complaints of lower abdominal pain and palpable masses found by themselves. Two of them had diabetes mellitus. The tumor sizes were all more than 10 cm. The diagnoses were made by histological examination of tissues removed at surgery. Two cases were categorized into the FIGO stage IIIc and one in stage Ia. Sonographic findings were characterized by a large adnexal mass with mixed components. An elevated serum squamous cell carcinoma antigen was found in the two cases of advanced stage and one of them also had an elevated serum CA-125 level. All reported cases were unilaterally involved without ascites at laparotomy, while omental lymph nodes metastases were noted in the two cases of advanced stage. One of the patients in the advanced stage died six months after surgery and radiation therapy due to recurrence. The other patient in the advanced stage refused further treatment even though recurrence was found five months after surgery and chemotherapy. There was no evidence of recurrence in the early stage case during the two years of follow-up.

We present the case of a 62-year-old Japanese man whose histological diagnosis was adenoendocrine cell carcinoma of the gallbladder at autopsy, but whose antemortem diagnosis was squamous cell carcinoma. The patient was admitted to hospital with complaints of occasional vomiting and abdominal pain. Abdominal computed tomography revealed a large tumor on the gallbladder involving the adjacent liver, colon, and duodenum, with multiple metastases in the greater omentum and paraportal lymph nodes. The serum level of squamous cell carcinoma antigen (SCCA) was high, whereas that of carbohydrate antigen (CA) 19-9, as well as that of carcinoembryonic antigen (CEA) was within the normal range. Due to these clinical features, we first suspected advanced squamous cell carcinoma of the gallbladder. After two cycles of gemcitabine monotherapy, the tumor had become enlarged and the regimen was changed to a combination of docetaxel and cisplatin. Though tumor regression was achieved and his serum SCCA level normalized after 3 months, the patient rejected additional chemotherapy and died 8 months after the diagnosis. The histopathological findings made by autopsy demonstrated the tumor to be an adenoendocrine cell carcinoma without squamous carcinoma cells. The case is interesting in that the clinical features were similar to those of squamous cell carcinoma of the gallbladder.
