“…Between 1930 and 2006, 61 cases of testicular carcinoid were published, in addition to the present case; the 62 cases comprised 44 in group 1 , six in group 2 [8,17,[41][42][43] and 12 in group 3 [8,16,[44][45][46][47][48][49][50][51][52]. Metastases were described in seven of the 44 cases in group 1 [8,9,15,28,29,32].…”

OBJECTIVETo review previous reports of carcinoid (an endocrine tumour mostly of the gastrointestinal tract) tumours of the testis.METHODSCarcinoid tumours of the testis are rare and can be divided into primary carcinoid (group 1), testicular metastasis from another location (group 2) and carcinoid within a testicular teratoma (group 3). A case of testicular carcinoid within our clinic prompted us to review previous reports; all the cases found were assessed for patient and tumour characteristics, diagnostic tools used, treatment and prognosis.RESULTSIn all, 62 cases were assessed and divided into groups 1 (44 patients), 2 (six) and 3 (12), respectively. Seven patients in group 1 developed metastases. A wide variety of diagnostic tools was used to search for other tumour sites. All patients were treated with orchidectomy. Three patients with a primary carcinoid were treated with adjuvant chemotherapy (two) or radiotherapy (one), with unknown results. All but one of the nine patients who died were known to have metastasis, either from a primary testicular carcinoid or testicular metastases from an intestinal carcinoid.CONCLUSIONWhen a testicular carcinoid tumour is discovered, other tumour sites should be excluded. The most useful diagnostic tools for this purpose seem to be urinary 5‐hydroxyindoleacetic acid measurement, somatostatin receptor scintigraphy, computed tomography and video‐capsule endoscopy. Localized testicular carcinoid tumours have an excellent prognosis after orchidectomy.

Eight cases of a primary mediastinal endocrine neoplasm with the appearance of carcinoid tumor are presented, and the 8 cases previously reported are reviewed. These neoplasms occur in adults, most often in males, and are located in the anterior or anterosuperior mediastinum. The only effective treatment is surgical excision. Their natural history is similar to carcinoid tumors of other locations, especially those arising from derivatives of the foregut. They are characterized microscopically by formation of rosettes, ribbons, and festoons; sheet‐like or medullary areas; and large “balls” with central necrosis and calcification. Their cytoplasm contains argyrophil granules and, by electron microscopy, “neurosecretory” granules. Some features of these neoplasms favor an origin from the thymus gland. However, they should be clearly separated from thymomas because of their different histogenesis, microscopic appearance, and natural history. It is suggested that the so‐called “epithelial thymoma” associated with Cushing's syndrome is related to the neoplasm discussed here.

Twelve carcinoid tumors of the uterine cervix were studied. Based on the microscopic structure, they were divided into well-differentiated a n d poorly differentiated types. Both tumor varieties affected adult women. The clinical and gross features of these tumors were indistinguishable from those of invasive squamous cell carcinoma. Of the 12 patients, six died, four with poorly differentiated carcinoid and two with the well-differentiated type. Three patients are alive and symptom-free 9 months to 2 years after treatment; the remaining three were lost to follow-up. Microscopically, four well-differentiated carcinoids showed argyrophil cells, and ultrastructurally two had neurosecretory granules. One of the well-differentiated carcinoids resembled islet cell carcinoma and two had areas resembling medullary carcinoma of the thyroid. The poorly differentiated type of carcinoid had a histologic structure and a cell population very similar to that of the oat cell carcinoma of the lung. Of this group, four were argyrophilic, and by electron microscopy four contained pleomorphic secretory granules. It is considered that these tumors arise from the normal argyrophil cell of the cervix and are part of the group of neoplasms of the diffuse endocrine cell system (APUD).
