[Morphological diagnostic problems in a case of peritoneal blastomycosis].

Blastomycosis is a mycotic disease, caused by a fungal infection. It has a wide spectrum of clinical presentations, and, particularly, can mimic neoplastic disease. Correct diagnosis of the illness requires fungal culture and biopsy. In Romania, mycotic histopathology is insufficiently developed, and morphological tests are recommended to very few people who present this type of pathology. The paper discusses a case of peritoneal blastomycosis found at a patient with an abdominal pseudotumoral mass. The microscopic exam revealed the characteristic histologic features and budding yeast, in specific dyes, typical to the Blastomyces dermatidis (PAS, silver-methenamin). Authors of this paper hereby intend to draw pathologists' attention on the existence and diagnosis of mycotic lesions, whose number is continuously increasing nowadays.
