Abstract：
BACKGROUND: Pigmented epithelioid angiomyolipoma is a variant of epithelioid angiomyolipoma (EAML) that has not previously been described in children with tuberous sclerosis.
METHODS: A 15-year-old boy with tuberous sclerosis had a rapidly enlarging renal mass associated with a left lung nodule. Microscopically it was a pigmented EAML, confirmed by immunohistochemistry.
CONCLUSIONS: The pigmented variant of EAML can arise and metastasize from the kidney of a teenager with tuberous sclerosis.

摘要：
背景：色素性上皮样血管平滑肌脂肪瘤是上皮样血管平滑肌脂肪瘤（EAML）的一种变体，以前尚未在结节性硬化症儿童中描述过。
方法：一名患有结节性硬化症的15岁男孩的肾脏肿块迅速增大，并伴有左肺结节。在显微镜下，这是一种色素沉着的EAML，通过免疫组织化学证实。
结论：EAML的色素变体可以从患有结节性硬化症的青少年的肾脏中产生并转移。
