title: Fine-needle aspiration cytology of subcutaneous toxoplasmosis: A case report.
abstract: Toxoplasmosis is a common opportunistic infection in patients with AIDS in whom it typically presents as encephalitis, pneumonia, lymphadenitis, and myocarditis. Skin involvement is very rare and, to our best knowledge, Toxoplasma gondii forming a subcutaneous mass has not been reported. Here, we report the findings of an interesting case of subcutaneous toxoplasmosis with the cytological appearance of an inflammatory fibrovascular lesion in a HIV-positive patient and discuss the differential diagnosis.
