Case of Chondroma in Prepubic Space: A Rare Occurrence

Abstract

The pelvic bone can be affected by a various diseases, including tumours. Cartilaginous tumours may develop in this area because it contains hyaline and fibrocartilage. The pelvis is known to host malignant tumours like chondrosarcoma. On the other hand, chondroma, a benign cartilaginous tumour, is occasional. Chondroma is known to occur in different osseous and extraosseous locations. Extraskeletal/soft-tissue chondroma, though rare, is known for its occurrence in various anatomical locations. Hereby, the authors present a case report of a chondroma in the prepubic space that manifested with urinary symptoms. A 58-year-old female, known to be diabetic, came with acute urinary retention. She experienced a recent onset of burning micturition and abdominal pain. Radiological and cytological findings were non diagnostic. During pelvic exploration, a solid mass of 3×3 cm was noted in the prepubic space without a connection to the urinary bladder or underlying bone. Excisional biopsy of the mass showed benign mature chondrocytes in a background of chondroid matrix, suggesting a benign cartilaginous tumour (chondroma). The patient is now free of her symptoms and is doing well during the follow-up at three months. Authors could not find any case reports of chondroma in the prepubic space in the literature. The present case of extraskeletal chondroma in the prepubic space is an infrequent entity at an unusual site.
