[Keratoacanthoma of the penis: A case report and literature review].

ABSTRACT

OBJECTIVE: To explore the clinical characteristics and treatment options of keratoacanthoma (KA) of the penis. METHODS: We report the diagnosis and treatment of a case of penile keratoacanthoma in our hospital and review the literature. RESULTS: The patient was admitted due to the discovery of a "new lesion on the glans for 4 months," diagnosed with a penile tumor, underwent tumor resection surgery, with histopathological examination revealing squamous epithelial hyperplasia, thickening, and excessive keratinization. The postoperative pathological diagnosis was penile keratoacanthoma. There was no recurrence or metastasis during follow-up. CONCLUSION: KA is a relatively rare benign tumor with potential malignant transformation, and close follow-up is necessary postoperatively.
