Pleomorphic spindle cell sarcoma of the adrenal gland: an extremely rare cause of a large abdominal mass and a challenging diagnosis.

Primary adrenal pleomorphic spindle cell sarcoma (PSCS) is an exceedingly rare mesenchymal tumour that was previously known as malignant fibrous histiocytoma. It commonly occurs in extremities, retroperitoneum, peritoneal cavity and rarely in visceral organs. We report the first case of PSCS in the left adrenal gland in a 65-year-old female who presented with a large abdominal mass with vague symptoms.
