[Malignant blue nevus].

In a 6-year-old boy, we found a malignant blue nevus with metastases of the lymph nodes. After surgical therapy under melanoma conditions, he was treated with interferon. Up to now (2 years after therapy), the follow-up examinations have been negative.

[Malignant fibrous histiocytoma of the prostate capsule].

This report deals with the clinical, ultrasonographical, computertomographical and morphological aspects of the rare malignant fibrous histiocytoma of the prostatic gland. A 80-year-old patient suffered from a fast growing painless tumor of the prostatic area, which, on microscopical examination, proved to be a malignant fibrous histiocytoma. The patient refused surgical treatment and died several weeks thereafter. On autopsy no metastases were found. The diagnosis of a malignant fibrous histiocytoma of the prostatic gland can only be made on microscopical grounds. The differential diagnosis includes a pleomorphic rhabdomyosarcoma or a pleomorphic liposarcoma. The clinical differential diagnosis includes, first of all, a carcinoma of the prostatic gland. Surgery is the therapy of choice. The prognosis of the malignant fibrous histiocytoma of the prostatic gland is poor.

[Mucoepidermoid carcinoma of the stomach].

A case report is given of a 65 year old female patient harboring a rare mucoepidermoid carcinoma of the stomach. On X-ray examination a smooth faced mass with a diameter of 3 cm was found in the corpus region of the stomach. During gastroscopy the tumor was seen to be localized in the lower third of the stomach close to the lesser curvature with an ulceration on top. On microscopic examination a cornified squamous cell carcinoma was found including interspersed mucilaginous adenocarcinoma tissue. Prognosis of mucoepidermoid carcinoma is bad, histogenesis controversial. Discussion of this case as well as of other unusual adenocarcinomas for example with trophoblastic differentiation has to include the possibility of bidirectional development of undifferentiated stem cells. However it still remains unclear, why such tumors of the stomach are almost always adenocarcinomas and not signet ring cell carcinoma.

[Segmental chlamydia proctitis].

A case report is given of a 28 year old homosexual suffering from segmental proctitis caused by Chlamydia. The patient had watery diarrhea and fever since 3 weeks. Stool specimen testing was negative in regard to Salmonella, Shigella and worm eggs. Infection with N. gonorrhoea, Herpes simplex virus, Toxoplasma gondi, Yersinia and M. tuberculosis could be excluded. Serological testing yielded results suggestive of an old lues infection successfully treated. On histological examination typical reticulocytary suppurating granuloma were found. Therapy of choice of Chlamydia-proctitis is tetracyclines.

[Nephrogenic adenoma of the urinary bladder with concomitant multiple adenomatous polyps of the large bowel. An abortive form of Gardner's syndrome? (author's transl)].

For the first time, a nephrogenic adenoma of the urinary bladder coinciding with multiple adenomatous polyps of the large bowel, in a 64-year-old male, is reported. The relationship of these tumors at different sites to a known clinical systemic disease is questionable; they could conceivably be ascribed to an abortive form of Gardner's syndrome. On the basis of a case report, the essential aspects of the nephrogenic adenoma of the urinary bladder are reviewed and discussed.

[Malacoplacia of the vagina, a rare cause of vaginal bleeding (author's transl)].

In a 74 years old woman who developed bleeding per vaginam following a paroxysm of cough colposcopic inspection revealed a yellowish-brown soft tissue of the mucous membrane of the upper vaginal vault. Microscopical examination showed a typical Malacoplacia of the vagina. Bleeding per vaginam resulted from ruptured vessels of this granulation tissue. This seems to be the 2nd case of a Malacoplacia of the vagina, as far as we are informed.

[Morphological changes in the hypopharynx-esophageal region following laryngectomy. II. Median-sagittal infolding above the ventral aspect of the hypopharynx-esophageal region (author's transl)].

This paper deals with the morphological findings in the hypopharynx-esophageal region of two patients following laryngectomy. In these patients we found a median-sagittal infolding, situated above the ventral aspect of the hypopharynx-esophageal region. This infolding was due to the surgical closure of the ventral wall of the esophagus, following laryngectomy. Histological examination revealed a hernia-like prolapse of the tunica mücosa, m. mucosae and tela submucosa with numerous proliferated macrophages and blood vessels, but no lymphatics. These macrophages are concerned with the removal of an edema, which, however, is only imperfectly removed and finally turns out into a fibrous tissue. The functional meaning of this infolding is not yet clear, but it seems intimately related to the altered function of the hypopharynx-esophageal region following laryngectomy.
