Primary adrenal leiomyosarcoma (PAL) is an extremely rare case finding where the mesenchymal tumor is found to be originating from the mesenchymal elements surrounding the adrenal vessels. Herein we report an interesting case of a 60-year-old gentleman, presenting to us with an abdominal lump. Contrast-enhanced computed tomography of the (CECT) abdomen revealed multilobulated heterogeneously enhancing soft tissue lesion of size 99 × 93 × 33 mm in the left supra renal region. After evaluation, the patient underwent an open left adrenalectomy. Postoperatively the histopathological examination showed mesenchymal neoplasm with spindle-shaped vesicular chromatin, conspicuous nucleoli, and eosinophilic cytoplasm with occasional atypical mitosis.
