A Rare Case of Malignant Melanoma of the Glans Penis in a Young Male Treated with an Organ-Preserving Surgical Procedure.

Penile melanoma is a rare and highly invasive cancer that is generally diagnosed in the sixth to seventh decades of life. We report a rare case of primary malignant melanoma of the glans penis in a 38-year-old man who presented with a proliferative lesion over the glans with discoloration for six months. The clinical and metastatic workups were unremarkable. Circumcision and biopsy performed outside showed characteristics of squamous cell carcinoma. We treated the patient with a partial penectomy, and the histopathological examination was suggestive of malignant melanoma. A stump revision with bilateral superficial inguinal lymph node dissection was performed. As per the oncologist's opinion, the patient underwent chemotherapy and immunotherapy after surgery. No recurrence or metastasis occurred during the one-year follow-up.
