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.
弓形虫病是艾滋病患者常见的机会性感染，通常表现为脑炎、肺炎、淋巴结炎和心肌炎。皮肤受累非常罕见，据我们所知，尚未有关于弓形虫形成皮下肿块的报道。在此，我们报告一例有趣的皮下弓形虫病病例，该病例为一名HIV阳性患者，其细胞学表现为炎性纤维血管病变，并讨论其鉴别诊断。
