Primary adrenal leiomyosarcoma: a case report and review of literature.

Primary adrenal leiomyosarcoma (PAL) is an extremely rare mesenchymal tumors and originates from the smooth muscle wall of the central adrenal vein and its branches. Herein we report a case of a 49-year-old female suffering from PAL. Computed tomography revealed a well-circumscribed heterogeneously mass measuring 6 × 5 × 5 cm located in the left suprarenal areal, and a left laparoscopic adrenalectomy was underwent. Microscopic examination showed a hypercellular tumor with intersecting fascicled of spindled cells. Immunohistochemical staining showed that the cells were positive for desmin, smooth muscle actin (SMA), vimentin and negative for CD34, CD117, S100, Bcl-2 and Dog1. No oncological treatment underwent after surgery, and the patient had no recurrence or metastasis at 6 months postoperatively.
