Penile Intraepithelial Neoplasia (PeIN) in a young man with the clinical appearance of Buschke Lowenstein Tumor

Abstract

Background: The incidence of penile cancer in the general population is rare. Epidemiologically, penile cancer occurs less than 1% compared to other types of cancer. Penile Intraepithelial Neoplasia (PeIN) is a precancerous lesion of invasive squamous cell carcinoma characterized by dysplastic changes of squamous epithelium with the intact basement membrane. This case report aims to increase understanding of Penile Intraepithelial Neoplasia (PeIN), especially with the clinical appearance of the Buschke Lowenstein Tumor, diagnosis, examination, and appropriate management.

Case Presentation: A 21-year-old Balinese man presented with a lump on his genitalia without itching, pain, and a lesion that bleeds easily, which has appeared since January 2022. He complained that the lump was getting bigger and bigger. Physical examination showed multiple hyperpigmented papules and plaques with well-defined oval and corn shapes that vary in size with a dense consistency and a verrucous surface. Laboratory tests showed negative on Hep-B and HIV tests. The patient also had a biopsy of the lump where the results showed Penile Intraepithelial Neoplasia. The patient was treated with 6 cycles of TCA 80% once a week, but it did not improve, so circumcision and surgical excision were carried out on June 2022. Fourteen days after surgery, multiple lumps appeared, recurred, and increased in number and size. On 1-month observation after the second surgery, the patient denied complaints of the genitals. Venerological status was within normal limits.

Conclusion: HPV-related Penile Intraepithelial Neoplasia (Warty subtype) with the clinical appearance of Buschke Lowenstein Tumor was reported in a 21-year-old Balinese man treated with Glans Resurfacing surgical excision with satisfactory results characterized by no functional abnormalities both during urination or erection.
