Primary Adrenal Leiomyosarcoma: Clinical, Radiological, and Histopathological Characteristics.

Primary adrenal leiomyosarcoma (PAL) is a rare, high-grade proliferating mesenchymal tumor with a considerable risk of metastasis, deriving from the smooth muscle wall of a central adrenal vein, or its tributaries. Roughly 40 patients with PAL have been reported in the literature. Herein, we present 3 patients with incidentally discovered PAL, along with an overview of the current knowledge on the clinical, radiological, and histopathological characteristics of PAL.
