“…Since then, only 17 cases have been reported in the English-language literature. 5 – 15 The penis lesion may originate from a single lesion in the embryo that is then divided during development of the external genitalia from the 11th to the 14th gestational week, which has been suggested by Desruelles et al 4 and Kono et al 6 Desruelles et al 4 hypothesized that that the problem is caused by the migration of the melanoblasts and melanocytes before completion of the invagination of the preputial epithelial placode. 4 In contrast, Kono et al 6 suggested that the migration of the melanoblasts occurs just after embryological separation of the glans from the prepuce, which occurs at 12 weeks.…”

Summary:Divided nevus of the penis is exceedingly rare. Desruelles et al. reported the first divided nevus on the penis in 1998, and, since then, only 17 cases have been reported in the English language literature. This article presents the successful excision and histopathologic evaluation of the nevi. The glans was reconstructed by a full-thickness skin graft using remnant foreskin. Six months after the operation, the patient showed no deformity of the glans and no loss of sensation. The lesion on the glans can be successfully reconstructed using the remnant foreskin with satisfactory aesthetic and functional outcome. This method is desirable with minimal donor-site morbidity and inconspicuous donor-site scars.

“… 8 Divided nevus of the penis is a kind of rare skin pigmented nevus. 9 Because it is located on the skin surface of the male external genitalia, the divided nevus of the penis may have a negative impact on the psychology of patients themselves and sexual partners. 10 In addition, with the gradual development of male sexual maturity and sexual behavior, the divided nevus of the penis has a certain risk of malignant transformation.…”

Objective To investigate the application of local rotation flaps for reconstruction of divided nevi of the penises in young male patients. Methods A group of 8 patients of divided nevi of the penises who underwent wound reconstruction with local rotation flaps after surgical lesion removal was enrolled in a retrospective clinical study. Postoperative complication, sexual function and psychological traits were evaluated during the follow-up. Results All patients, with ages ranged from 16 to 32 years (mean 23.25 years), were followed up for 6 to 48 months (mean 19.86 months). The patient’s average length of hospital stay was 7.85 day (7 to 15 days). The average dimension of the lesions was (2.31±0.44) × (1.46±0.48) cm 2 on the glans and (1.38±0.40) × (1.01±0.46) cm 2 on the inner prepuce plate. All patients had no postoperative infection and were satisfied with the postoperative outcome upon discharge. Five cases of benign intradermal nevi and 3 cases of compound nevi without malignant transformation were confirmed by pathological evaluation on the removed samples. The sexual function of all patients was unaffected postoperatively by male sexual function scale (BMSFI and IIEF-5) evaluation. The psychological status of depression, anxiety and stress was all improved after the surgical reconstruction confirmed by the psychological traits scale (DASS) evaluation. Conclusion Reconstruction with the local rotation flap is a simple, safe and appropriate surgical procedure, achieves satisfactory cosmetic outcome, and maintains intact male sexual function when used for the repair of defect after removal of divided nevi of the penises.
