Keynote webinar | Spotlight on sleep in brain health

LIVE: Thursday 2nd May 2024, 18:00-19:30 (CEST)

Quality sleep is essential for health. But what happens to our brains when sleep patterns are disturbed? Join our experts to explore the interplay between sleep disruption and neurological diseases, and the questions that you need to be asking your patients to help you prevent the harmful effects of sleep deprivation.

Abstract

Epithelioid angiomyolipoma (eAMLoma) is an uncommon renal mesenchymal tumor with malignant potential. It is composed of tumor cells arranged in an epithelioid manner. Differential diagnosis from renal cell carcinoma is often challenging because of its epithelioid morphology. Herein is reported a case of eAMLoma, involving a 49-year-old man with eAMLoma. The patient had undergone radical nephrectomy via retroperitoneal laparoscope successfully. He had an uneventful postoperative recovery. The tumor was positive for Desmin, Hmb45, and Sma. We recommend surgical treatment and a follow-up regimen similar to that for renal carcinoma. There was no recurrence and metastases after 1-year follow-up.
