OBJECTIVETo study the clinicopathological characteristics, immunohistochemical features and histogenesis of primary testicular carcinoid tumor and its differential diagnosis.

METHODSLight microscopy and immunohistochemical stains were performed in 4 cases of primary testicular carcinoid tumor.

RESULTSThe patients sought care for scrotum mass presented from 2 to 36 years, 2 cases accompanied with tender swelling of the testis. The tumors were described as nodular, yellowish-gray in color, 3.0-4.0 cm in the greatest dimensions, and well circumscribed, focal necrosis seen in 1 case. Histologically, they showed insular and trabecular patterns separated by fine fibrous bands. The tumor cells were round or polygonal with regular monomorphic nuclei, stippling chromatin and eosinophilic granular cytoplasm. There were rosette-like and tubuloglandular patterns with eosinophilic secretion in the cavity. Immunohistochemical staining for synaptophysin, chromogranin A, NSE and cytokeratin showed diffusely positive expression in the tumor cells.

CONCLUSIONPrimary testicular carcinoid tumor is extremely rare with good prognosis and its histogenesis remains controversial. Diagnostically it has to be differentiated from seminoma, metastatic carcinoid tumor, Sertoli cell tumor and granulosa cell tumor.

This is the first case report of a patient with a large serous cystadenoma accompanied by a juvenile granulosa cell tumor that was discovered in the remaining ovarian tissue. A 25-year-old female was presented with constipation and amenorrhea. Ultrasonography revealed a large cystic mass in the left ovary with a normal uterus. The remaining ovarian tissue seemed normal at first look after cystectomy, but showed abnormal consistency on palpation. The remaining ovarian tissue was removed and granulosa cell tumor was confirmed by pathologic examination. The patient has been followed up for 30 months without evidence of recurrence. We would like to emphasize the importance of inspection, and palpation of remaining ovarian tissue during operation to avoid risks of remaining ovarian pathology.

A 54-year-old woman was admitted to our hospital complaining of postcoital bleeding. Sonography of the abdomen showed a 8.2 x 8.9 cm-sized solid heterogeneous mass occupying the cul-de-sac, which appeared to be in no way connected with the ovary. On exploratory laparotomy, the tumor mass protruded from the posterolateral retroperitoneum of the pelvic cavity and severely replaced the uterus and adnexa with the outer surface being grossly intact. It grossly measured 10 cm in maximal diameter. The histologic features closely resembled those of ovarian granulosa cell tumor. The primary extraovarian granulosa cell tumor is extremely rare such that in the English literature only 7 cases have been reported to date. Of those granulosa cell tumors are especially rare and only two cases have been reported to arise from retroperitoneum. We herein present a case of retroperitoneal granulosa cell tumor with special regard to differential diagnosis from other solid tumors with similar histology.

We report a case of adult granulosa cell tumor arising in the scrotal tunics. The patient was a 34-year-old man who presented with right scrotal swelling, first noticed four months previously. Under the initial clinical impression of epididymo-orchitis, antibiotic treatment was instituted but there was no response. The paratesticular nodules revealed by ultrasound and magnetic resonance imaging mimicked intratesticular lesion, and radical orchiectomy was performed. Although several cases of adult testicular granulosa cell tumor, have been reported, the occurrence of this entity in the paratesticular area has not, as far as we are aware, been previously described.

We report a rare case of a giant ovarian tumor presenting as an incarcerated umbilical hernia. A 61-yr-old woman was admitted to the hospital with severe abdominal pain, an umbilical mass, nausea and vomiting. On examination, a large, irreducible umbilical hernia was found. The woman underwent an urgent operation for a possible strangulated hernia. A large, multilocular tumor was found. The tumor was excised, and a total abdominal hysterectomy and bilateral salphingo-oophorectomy were performed. The woman was discharged 6 days after her admission. This is the first report of incarcerated umbilical hernia containing a giant ovarian tumor within the sac.
