The literature contains few references to this entity and, in epidemiological terms, most published cases are of patients of Indian ethnicity.</p><p id="par0035" class="elsevierStylePara elsevierViewall">Its etiology is currently the subject of debate. The disease has 4 clinical stages: initial or plaque stage, late tumoral stage, warty carcinoma, and transformation into squamous cell carcinoma.</p><p id="par0040" class="elsevierStylePara elsevierViewall">Histopathology typically reveals the following changes: hyperkeratosis, parakeratosis, acanthosis, elongated papillary crests, and mild dysplasia in the basal layers. Nonspecific inflammatory infiltration may be observed in the superficial dermis, with variable numbers of lymphocytes and eosinophils.<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">2</span></a></p><p id="par0045" class="elsevierStylePara elsevierViewall">Some authors have questioned the potential for this rare form of balanitis to become malignant, but an increase has been reported in the number of recorded cases of warty carcinoma and squamous cell carcinoma arising from PKMB lesions, either at the time of presentation or later.<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">2</span></a> Careful follow-up of these patients is therefore important. To date, no link has been found between PKMB and HPV. In 1 case of warty carcinoma from PKMB, in situ hybridization and PCR were negative for HPV in the tumor and in the precancerous lesion.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">3</span></a></p><p id="par0050" class="elsevierStylePara elsevierViewall">The differential diagnosis should include 3 approaches: infectious causes, with sexually transmitted diseases such as genital herpes simples, soft chancre, and primary syphilis; inflammatory causes, with diseases such as hypertrophic lichen planus and Zoon plasma cell balanitis; and oncologic causes, with penile intraepithelial neoplasia (PeIN), warty carcinoma, squamous cell carcinoma, keratoacanthoma, giant condylomatosis, and erythroplasia of Queyrat.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">4</span></a> The absence of atypical cells in PKMB histology may be a key finding that makes it possible to differentiate it from oncologic entities, although correlation with the clinical presentation is necessary.</p><p id="par0055" class="elsevierStylePara elsevierViewall">Early clinical diagnosis and biopsy of the lesion are of considerable value, as the disease can be treated topically with 5-fluorouracil,<a class="elsevierStyleCrossRefs" href="#bib0035"><span class="elsevierStyleSup">1,5</span></a> which produced a good response in our patient.
