Fine-needle aspiration cytologic diagnosis of lymphocutaneous sporotrichosis: a case report.

A case of lymphocutaneous sporotrichosis initially diagnosed by fine-needle aspiration (FNA) cytology and confirmed by tissue biopsy and culture study is presented. Asteroid bodies and yeast cells with budding, highly suggestive of the disease, were seen in the cytologic and histologic preparations. The pathology of this unusual fungal disease and the role of cytology in the diagnosis are discussed. This is the first case of lymphocutaneous sporotrichosis reported in the cytologic literature as diagnosed by FNA cytology.
