Case Report: Primary Ewing Sarcoma of the Penis.

Ewing sarcoma is a malignancy that commonly affects the skeletal system and primary extraskeletal involvement is rare. Extraskeletal Ewing sarcoma (EES) arises in soft tissue anywhere in the body. These are very rarely seen aggressive tumours. There have been only 7 reported cases of EES of penis.

We report a 22-year-young patient who presented to our hospital with a ulcero-proliferative growth in the shaft of penis. There were no other complaints indicating any metastasis. Incisional biopsy was suggestive of invasive malignancy. He was scheduled for a partial penectomy. Final HPE and IHC were suggestive of EES.

EES as a subtype of Ewing sarcoma is rare and it can occur in any soft tissue site. Hence, clinicians need to differentiate this entity from other soft tissue sarcomas. Early diagnosis and timely treatment of EES are pivotal for a favourable prognosis due to its aggressive nature.
