[Plasmacytomas of the upper respiratory tract]. / Plazmotsitomi na gornite dikhatelni putishta.

ABSTRACT

Nine cases of plasmocytoma of the upper airways in the current biopsy material are studied over a three-year period (1991-1993). Initially, all nine cases are clinically diagnosed as neoplasms hemangiofibroma--one, chondrosarcoma--one, suspected carcinoma--five, and unspecified diagnosis--two. "Plasmocytoma" diagnosis is made on the ground of histological investigation of the material, supported histochemically and electron-microscopically. Some diagnostic problems (differential diagnosis inclusive) are discussed, as well as issues relating to the clinical and morphological evolution of the disease, and predilected gender and age groups.
