Pseudoepitheliomatous, keratotic, and micaceous balanitis

Abstract

A 51-year-old circumcised male presented with hard, thick, keratotic, nail-like covering of the skin of his glans penis of 2 year duration. Histology showed acanthosis, papillomatosis, and elongated rete ridges into the dermis suggestive of pseudoepitheliomatous, keratotic, and micaceous balanitis with features of cellular atypia. Partial penile amputation was done. There was no recurrence after 6 months of follow up.

Pseudoepitheliomatous, keratotic, and micaceous balanitis mimicking lichen sclerosus et atrophicus

“…More rarely, invasive squamous cell carcinoma develops [4]. It has been suggested that PMKB is a pseudoepitheliomatous response to chronic inflammation [5]. Some authors think that PMKB is a complication of chronic, untreated or burnt-out lichen sclerosus et atrophicus [6].…”

Pseudoepitheliomatous keratotic and micaceous balanitis

“…It is proposed to be a form of pyodermatitis or pseudoepitheliomatous response to infection. [6] Though PKMB is described as a distinct entity, there is considerable overlap with verrucous carcinoma. [78] It is also considered to be a variant of lichen sclerosus.…”

Treatment of pseudoepitheliomatous, keratotic, and micaceous balanitis with topical photodynamic therapy

“…1 Characterized by a silvery white plaque with a mica-like crust, 2 PKMB was first described in 1961. 1 Characterized by a silvery white plaque with a mica-like crust, 2 PKMB was first described in 1961.…”

“…Pseudoepitheliomatous, keratotic, and micaceous balanitis (PKMB) is an extremely rare condition occurring over the glans in older men who undergo circumcision late in life. 1 Characterized by a silvery white plaque with a mica-like crust, 2 PKMB was first described in 1961. 3,4 Its exact etiology is unknown.…”
