ABSTRACT Adenocarcinoma of the rete testis is a rare tumor that tends to occur in men over the age of 60 and is usually associated with a poor prognosis. We report such a tumor occurring in a 63-year-old male 2 years after he underwent a scrotal exploration in the management of a hydrocele, varicocele, and inguinal hernia. The postorchidectomy course was characterized by slowly advancing, painful scrotal and perineal skin recurrences, lymph node metastases, and the absence of response to Adriamycin and electron-beam therapy. We are confident that the lesion is a carcinoma of the rete testis because: 1) the tumor is situated mainly in the testicular mediastinum, 2) primary germinal and nongerminal testicular tumors and spread from distant sources have been excluded, 3) a transition from normal rete testis to atypical and neoplastic rete epithelium is demonstrable, and 4) the transmission electron-microscopic findings support our conclusion. The distinction between carcinoma of the rete testis and malignant mesothelioma may be difficult and requires consideration of the gross, light-microscopic, and ultrastructural tumor characteristics in optimally fixed tissue.

    ABSTRACT: Adenocarcinoma of the rete testis is a rare tumour with a varied presentation. A total of 44 cases have been reported [1]. Of these testicular tumours, primary nongerm cell tumours account for a minority of cases. Among this, adenocarcinoma originating in the rete testis is still rarer. It is a highly malignant tumour with poor prognosis. It is generally diagnosed clinically as a solid or cystic swelling. However, confirmation is made only on histological diagnosis.

    ABSTRACT: A testicular tumor, removed from a 52-year-old man, was composed of uniform spindle cells and abundant interposed collagen, and was histologically diagnosed as a stromal tumor. Electron microscopy revealed cords of cells sometimes surrounded by a basal lamina. Desmosome-like junctions were found between some cells, and immunostaining for desmoplakins was positive. Immunofluorescence studies also showed cytokeratin-positivity in most and vimentin-positivity in some of the tumor cells. The presence of typical simple epithelial cytokeratins of Mr 40000, 45000 and 52000 was revealed by the western blotting method. Cytokeratin positivity in the tumor cells suggests the epithelial nature of this mesenchymal-looking tumor. The tumor might arise from cytokeratin-positive epithelial elements of the testis or its covering mesothelium, but the histogenesis remains unresolved. Our findings suggest that some of the so-called testicular stromal tumors may in fact be of epithelial nature by presenting features typical of epithelial differentiation.

    ABSTRACT: A case is presented of a 50-year old man with a unilocular cystic intratesticular tumour exhibiting the morphological features demanded from WHO for the diagnosis of serous papillary cystadenoma of the ovary. Keratin filaments could be demonstrated in the cyst lining and papillae covering cells by means of PAP-technique; AFP and SP-1 were lacking. The epithelial cells of the tumour showed a lectin binding pattern (WGA, UEA-I, PNA, Con A, PSA, LCA, RCA) different from the epithelium of rete testis and epididymis. We intend to classify our tumour as the male analogue of the respective ovarian growth.
