Background: Pediatric penile hamartoma is extremely rare. Preoperative imaging often cannot definitively characterize the lesion, and histopathology remains the diagnostic gold standard. We report a child with penile hamartoma and torsion, discuss management, and compare outcomes with the literature. Methods: We retrospectively analyzed the clinical presentation, imaging, intraoperative findings, and pathology. Relevant reports were reviewed for comparison. Results: Complete excision of a ventral hamartomatous appendage plus circumcision and release of a fibrous tethering band achieved immediate torsion correction in a single stage. Histopathology showed stratified squamous epithelium with proliferative fibrous and adipose tissue containing nerve bundles, ganglion cells, and focal smooth muscle— consistent with hamartoma. Recovery was uneventful; at 12 months no recurrence was observed. Conclusion: Etiology‑targeted, one‑stage correction—degloving (circumcision), release of tethering bands, complete lesion excision, and simultaneous torsion repair—can be safe and effective. Long‑term follow‑up is advised.
