[Pathohistological characteristics of dermatophytic onychomycosis].
A pathohistological study was made of the tissues taken from the distal phalanx of the great toe of 30 dead bodies with clinical picture of mycotic infection of nail plates. Onychomycosis was confirmed by the presence of pathogenic fungal myceliem detected microscopically. It is established that the fungus, in total onychomycosis, penetrates from the nail plate into the skin epidermis, connective tissue, bone and into the bone marrow of the phalanx. Cyst formation was found deep in the prickle-cell layer. Inflammation was rather weak reflecting a weak reactive response to the fungus presence.
Epidermis↗
[Cutaneous pseudolymphomas].
Histological and immunohistochemical characteristics of principal types of skin pseudolymphomas, their differential diagnosis with true skin lymphomas are outlined.

[Detection of the human immunodeficiency virus in a lymphocyte culture from a patient from Central Africa with acquired immunodeficiency syndrome and Kaposi's sarcoma].
The results of HIV virus isolation from patient A. T., resident of Central Africa, are discussed, in whom Kaposi sarcoma was diagnosed clinically and histologically, and immunological examinations revealed the acquired immunodeficiency syndrome (AIDS). Cocultivation of the peripheral blood leukocytes of the patient with normal donor leukocytes yielded a leukocyte culture in which HIV virus expression was demonstrated. The HIV antigen was detected in the ultracentrifugate of the cultures by means of indirect enzyme-immunoassay using sera to the virus from the standard kits of Organon (Netherlands) and Abbot (USA). HIV antigen was also detected on the surface of lymphocytes in the culture by indirect immunofluorescence using the same sera. Besides, reverse transcriptase activity was demonstrated in ultracentrifugates of the culture fluid by exogenous reverse transcription test using poly(zA)-oligo(dT) matrix.
Acquired Immunodeficiency Syndrome↗
[Bacillary generalized angiomatosis in HIV infection].
A unique case of generalized bacillary angiomatosis (BA) in a patient who died of HIV infection is described. Apart from widely spread skin lesions there were also manifestations in the brain, lungs, heart, esophagus and intestine. Gram-negative bacteria were found in the histological sections. Oval and roundish bacteria with a predominantly perivascular location were found electron microscopically in the archives material.
