DefinitionThis section has been translated automatically.
Pigment incontinence with loss of melanin from the basal cell layers of the epidermis. The pigment that has passed through the dermoepidermal basement membrane accumulates in melanophages in the upper corium. This is caused by inflammatory processes in the corium, which cause damage or complete destruction of the melanocytes.
