[Diseases of the penis--the morphological diagnosis of biopsy material].

Diseases of the penis account for a minor part of the general biopsy materials sent for examination, and usually represent varying in nature inflammatory processes and tumors. In the laboratory of andrology and mammary pathology of the department of pathoanatomy and cytopathology with the Alexander Hospital-Sofia, a total of 65 biopsies from the penis are investigated over an eight-year period. The greatest share of the latter is assigned to tumors and tumor-like processes (47.

[Polypous endocarditis of the tricuspid valve. The morphological changes in the heart and lung in one case].

A case of polypous endocarditis which affects the tricuspid valve and whose genesis remains unclear (a septic state, an idiopathic disease?) is described. Clinically the disease has taken its course as a chronically recurring form of pulmonary thromboembolism. Morphologically it concerns to a massive fibroplastic verrucous endocarditis of the tricuspid valve and a more slightly expressed similar process in the wall of the right atrium and ventricle, combined with a significant fibrosis of the myocardium.

[Immunohistochemical and electron microscopical study of the myoepithelium in mastopathy and carcinoma of the mammary gland].

Biopsies obtained from 45 cases of invasive ductal carcinoma and 41 cases of cystic mastopathy were immunohistochemically investigated, with electron microscopy being used on some of them, for the purpose of clearing up presence, distribution, and ultrastructural peculiarities of the myoepithelial cells. Focal or diffuse myoepithelial proliferations were observed in all cases of cystic mastopathy, with peripheral layers of myoepithelium at the basal membrane being widely preserved. Myoepithelial cells had lost their normal position and cellular orientation in the regions with intraductal carcinoma.

[Clinico-morphological studies of epididymal cysts].

A clinico-morphologic study of epididymis cysts was made in 52 patients at mean age 39.4 years, observed over a period of 2 ys. 4 mos.

[Inflammatory processes of the breast].

Results are reported of a statistical study of the inflammatory processes in the mammary gland, based on data of the biopsy files at the Department of Pathology of the Research Medico-Biological Institute in Sofia for the period 1981-1985. Among 1498 biopsy specimens examined during this period, there were 27 cases of mastitis (1.8 per cent: 5 acute mastitis, 12 chronic diffuse, 10 granulomatous (one of them tuberculous), 2 lipogranulomas and 7 foreign type granulomas.
