[Pseudosarcomatous fibromyxoid tumor in the spermatic cord]

A case of fibrous pseudotumour in the spermatic cord is described. The patient had a large hydrocele, at the edge of which a tumour seven cm in diameter consisting of pleomorphic cells of fibrohistiocytic or myofibroblastic type was found. The patient has been followed for 18 months, with no signs of recurrence, but the biologic potential of this type of tumour has yet to be decided.

Lymphoepithelioma-like carcinoma of the vulvar region

A case of lymphoepithelioma-like carcinoma of the vulvar region is described. Histologically, the tumour was similar to lymphoepithelioma of the nasopharynx but was Epstein-Barr virus negative. Infiltrating lymphocytes were predominantly T-cells, but also included some B-cells. Immunohistochemical stains showed positivity in tumour cells for cytokeratins but negativity for neuroendocrine markers, the melanoma-associated antigen. HMB45 and leucocyte common antigen. We conclude that the tumour histologically resembles lymphoepithelioma of the nasopharynx and lymphoepithelioma-like carcinomas of the skin, and has no relation to prior infection with the Epstein-Barr virus.

[Granulosa cell tumor. A 30-year material from a central hospital]

During a 30-years period seventeen women were correctly diagnosed as having a granulosa cell tumour. Two died of the tumour, while six women died of other causes. No pathological features correlated to prognosis. A conservative surgical approach to preserve fertility is not recommended; of the three fertile women in our group one died of the disease and another one had two relapses within three years. Eleven tumours showed evidence of increased oestradiol production, and this proved useful as a tumour marker. Follow up is rarely performed unless relapse occurs.

Intratubular germ cell neoplasia in an infantile testis with immature teratoma

A case of intratubular germ cell neoplasia adjacent to an immature teratoma is described in an 8-month-old boy with normally descended testes. The pattern of intratubular germ cell neoplasia in the infantile testis appeared different from that in the adult, but the abnormal germ cells were morphologically and immunohistochemically similar. In the few previous reports, which have investigated infantile testicular tissue for the presence of intratubular germ cell neoplasia adjacent to germ cell tumours, intratubular germ cell neoplasia in conjunction with a yolk sac tumour and mature teratoma have not been found, and cases with immature teratoma have not been reported. The presence of intratubular germ cell neoplasia in conjunction with immature teratoma and its apparent absence in conjunction with the mature form and with yolk sac tumour may indicate difference in tumour development. Whether there is a true difference in the occurrence of intratubular germ cell neoplasia in the infantile testis according to the various types of germ cell tumours remains, however, to be proven by investigations of more cases.
