Erythroplasia of Queyrat - Anogenital in
The distinction between these 2 terms lies in the clinical appearance. The lesions of Bowen's disease arise on keratinizing epithelium, may itch in some cases and often appear scaly, while the lesions of EPQ are typically found on mucosal or transitional surfaces, commonly are asymptomatic (although rarely they may be pruritic), and present as erosions, ulcers, and "moist"-appearing lesions. EPQ commonly presents as an asymptomatic, isolated lesion on the glans penis but may involve the foreskin and the distal shaft of the penis as well. It is usually seen in uncircumcised older adults and may be associated with chronic balanoposthitis. HPV types 16 and 18 are implicated in many cases of EPQ. Bowen's disease occurs equally on sun-exposed and non-sun-exposed skin. In the past, arsenic exposure was the most common cause. Today HPV, as with EPQ, has been implicated in many cases.
If left untreated, the lesions of Bowen's disease or EPQ will eventually develop into SCC, an invasive tumor.
