Rough pigmented skin around the upper gluteal cleft —the condition called senile gluteal dermatosis, hyperkeratotic lichenified skin lesion of gluteal region, ano-sacral cutaneous amyloidosis and gluteal skin roughness

Abstract

Rough pigmented skin is often seen around the upper gluteal cleft in the elderly. It is considered to be induced by friction, pressure and long hours sitting. Some cases revealing amyloid deposits may be accompanied by other cutaneous amyloidosis. Bedsores and fungal infection can occur as complications. This condition should be known widely among people taking care of the elderly.
