What is Dermatitis Neglecta?

Dermatitis neglecta (also called unwashed dermatitis) is a benign cutaneous condition produced by accumulation of corneocytes, sebum, sweat, debris and bacteria on body areas that are chronically not washed adequately.

It typically appears as well-demarcated brown to black, adherent, hyperkeratotic plaques on the trunk, around painful areas (e.g., post-surgical, post-trauma), in immobilized patients, or on regions inaccessible to the patient.

Diagnosis is clinical and confirmed by easy removal of plaques with 70% isopropyl alcohol or soap-and-water; differential includes terra firma-forme dermatosis (which usually requires alcohol), acanthosis nigricans, confluent and reticulated papillomatosis and tinea versicolor.

Symptoms
