Background:
Epithelioid hemangioendothelioma (EH) is a rare vascular neoplasm with an unpredictable malignant potential that has been described mainly in soft tissue, liver, and lung.
Case Report:
We report a case of a primary renal EH in a 54-year-old woman who presented with a 3-month history of abdominal pain. Abdominal ultrasound and computed tomography scan revealed a solitary mass of 4.0 x 3.2 cm in the outer surface of the right kidney. Nephron-sparing surgery was performed. On the basis of the histological and immunohistochemical findings, the diagnosis of EH was made. The patient was free of disease 6 months after surgery.
Conclusions:
Although EH may have a histologically benign appearance and can be treated using a nephron-sparing approach, this neoplasm is potentially malignant urging the need for a long-term follow-up in these patients.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
