Abstract


Amyloidosis cutis dyschromica (ACD) is a rare form of cutaneous amyloidosis, characterized by generalized, asymptomatic hyperpigmentation intermingled with several hypopigmented spots without papulation, atrophy and telangiectasia. Its onset usually begins before puberty. We hereby describe two female siblings of ACD belonging to tribal groups with no systemic involvement. This condition should be considered as a separate entity and need to be differentiated from other variants of primary cutaneous amyloidosis.
