title: Epithelioid angiomyolipoma in a child--a diagnostic dilemma.
abstract: Epithelioid angiomyolipoma (EAML) is a rare variant of angiomyolipoma found to have malignant potential and poorer prognosis. It is characterized by the predominance of epithelioid cells and frequent association with tuberous sclerosis. Its usual age of presentation is between the fourth and fifth decades of life, and only a single case has been reported in the pediatric age group. In this study, we report a case of epithelioid angiomyolipoma in a 4-year-old child with features of tuberous sclerosis, which is the youngest age of presentation.
