Abstract

Epithelioid angiomyolipoma (EAML) is a rare mesenchymal neoplasmic variant of angiomyolipoma characterized by aggressive growth and unpredictable outcome. Cases of local recurrence and distant metastasis have been described. The histopathological diagnosis may be difficult, as EAML often mimics other neoplasms. This is the case report of a 39-year-old male patient with EAML, which was initially diagnosed as adrenal cortical carcinoma, due to the lack of cooperation between clinicians and pathologists.

Keywords: adrenal cortical carcinoma; epithelioid angiomyolipoma; histopathological diagnosis.
