Pseudoepitheliomatous keratotic and micaceous balanitis, (PKMB) is a cutaneous condition characterized by skin lesions on the glans penis that are wart-like with scaling.
The histological examination reveals a non-specific dermal inflammatory infiltration, lymphocytes and eosinophils, hyperkeratosis, parakeratosis, acanthosis, elongated rete ridges, and mild lower epidermal dysplasia.
[7] The histological examination reveals a non-specific dermal inflammatory infiltration consisting of lymphocytes and eosinophils, together with hyperkeratosis, parakeratosis, acanthosis, elongated rete ridges, and mild lower epidermal dysplasia.
[2] Differential diagnosis of PKMB includes other diseases on male genitalia-like giant condyloma, squamous cell carcinoma, psoriasis, and erythroplasia of Queyrat.
[9] PKMB was once thought to be a completely benign illness,[10] but new research has revealed that it is actually a unique entity that spans a histologic spectrum from verrucous carcinoma to hypertrophic-hyperplastic penile dystrophy.
