Giant Mesothelial Cyst of the Spermatic Cord: A Report of a Rare Case

Mesothelial cysts are uncommon benign lesions formed by mesothelial cells that line the serosal surfaces of many organs. It is commonly found in the peritoneum and less commonly in the pleura; when found in the spermatic cord, they are exceedingly rare. These cysts usually appear as painless lumps in the inguinal or scrotal area and often remain asymptomatic. Here, we describe a 64-year-old male who presented with scrotal swelling for four years and was clinically diagnosed with a spermatocele. He was taken up for an excision biopsy. The histopathology of the cyst was consistent with a mesothelial cyst. Herein, we discuss the clinical presentation, diagnostic approach, and management with a review of the literature on this uncommon entity.
