Background: Carcinoid tumors usually originate from the enterochromaffin cells located in gastrointestinal tract and bronchopulmonary system. They may rarely arise in the urinary bladder, where this can be eventually miscued as any other commoner bladder neoplasms. The current study was conducted to connote an uncommon clinicopathological presentation by a carcinoid tumor in the urinary bladder. Case: A 52-year-old male, who initially experienced obstructive urinary symptoms, underwent cystourethroscopy to remove a tumor in the urinary bladder. The tumor exhibited insular, trabecular, and organoid architecture on histology without any necrosis or mitosis, stained positively with chromogranin A, and thereby, confirmed the diagnosis of a pure carcinoid tumor. Conclusion: Carcinoid tumors rarely arise in the urinary bladder and other genitourinary organs. But, several other and relatively more common bladder neoplasms may often deceptively simulate it. This dilemma could be resolved easily with the application of proper immunohistochemistry (IHC) in neuroendocrine tumors.

Primary ovarian carcinoid tumors of the ovary are rare and represent less than 0.1% of ovarian malignancy. One of its subtypes is the strumal carcinoid in which the thyroid tissue is seen in intimate association with carcinoid tumor. We here report a 47-year-old woman with strumal carcinoid of the right ovary presented with cessation of menstrual periods in the past 3 months and was referred due to a possible menopause-related symptom. A firm pelvic mass was found in physical examination and a large mass (20 × 15 × 8 cm) in the right ovary was reported in ultrasound evaluation. The spiral CT scan reported masses in both ovaries. The patient underwent total abdominal hysterectomy plus bilateral salpingo-oophorectomy. The pathological evaluation revealed strumal carcinoid tumor with thyroid tissue in right ovary and benign cystic teratoma in left ovary. Our case was alive at 8 years after the operation with no disease recurrence.
