title: Amyloidosis cutis dyschromica in two siblings and review of the epidemiology, clinical features and management in 48 cases.
abstract: Amyloidosis cutis dyschromica (ACD) is a rare form of primary cutaneous amyloidosis (PCA). There is a paucity of information in the dermatology literature to guide its diagnosis, investigation and treatment. We present two siblings with ACD and summarise the epidemiology, clinical features, natural history and treatments in 48 cases of ACD from the literature. Familial cases were more common (37) than sporadic cases. ACD is predominantly reported in those of East and South-East Asian ethnicity (63%). The mean age of onset was 6 years in familial cases, and 23 years in sporadic cases. The clinical features of familial and sporadic ACD do not differ substantially. Pruritus was the only symptom, and was reported in 19% of all cases. There were no reported ACD cases with systemic amyloidosis. Acitretin was reported to result in improvement in seven of 10 patients treated. Routine investigation for systemic involvement is not necessary. Acitretin may be helpful.
