[Mucinous tubular and spindle-cell carcinoma of the kidney].

4 cases (2 males and 2 females) of mucinous tubular and spindle-cell carcinoma of the kidney were studied. The patients' age was 43 to 87 years. Microscopically, this tumor comprised two major cell populations. One of them involved spindle cells with a sparse cytoplasm, which were arranged in the fascicular pattern, often resembling low-grade smooth muscle tumors. The other population was small cuboidal cells with round nuclei and an eosinophilic cytoplasm. The mitotic activity was low. Only one tumor had both cell components. The other three tumors were represented by the second type cells. Immunohistochemical staining with avidin-biotin was performed by using cytokeratin, vimentin, SMA, p53, Bcl 2, EMA, and CD10. All cases were stained positively with antibodies to the cytokeratins AE1-AE2 and vimentin. The expression of EMA, Bcl 2, and CK7 was varying in different tumors. Responses to smooth muscle actin, p53, CK20, and CD10 were negative in all cases. Mucinous tubular and spindle-cell carcinoma of the kidney should be differentiated from angiomyolipoma with the preponderance of a leiomyomatous component, renal smooth muscle neoplasms, metanephrotic adenoma, and renal cell carcinoma with sarcomatoid differentiation.

[Circulatory disorders of the pituitary gland in neurosurgical pathology of the brain].

Histological study of 206 hypophyses of patients who had died from various neurosurgical diseases of the brain showed circulatory disorders in the hypophysis to be of the haemorrhagic type in 15.53% and the ischemic type in 9.22% of cases. The pathoanatomical characteristics of hemorrhages and infarcts of the hypophysis is given, the pathogenesis of these disorders is discussed, and the leading role of mechanical factors in the development of disorders of blood circulation is pointed out.

[The classification of aneurysms of the cerebral arteries].

Brain aneurysms are generally subdivided into so-called congenital and acquired (atherosclerotic, embolic and others). This classification does not reflect the reality as more than twenty brain aneurysms of different origin are already known. The classification suggested by the author is grounded on two interconnected features--etiology and pathogenesis--and uses also the term "bifurcation-hemodynamic aneurysms" (instead of so-called congenital aneurysms). This term reflects current understanding of aneurysm etiology and allows one to overcome the psychological barrier which prevented to create a rational classification.

[Polycystosis of the brain].

This paper presents a case with 11-year history of disseminated cerebral polycystosis in a 23-year-old female. Physical examination and CT, MRT, histological and biochemical data suggest that the disease is morphologically progressive; however, the spread on brain lesions showed no correlation with relatively mild clinical manifestations of the disease. Variants of nosological interpretation of histological data are discussed.
