Abstract: Primary cutaneous amyloidosis is a rare progressive disease that is characterized with the deposition of amyloid under the skin instead of internal organs. Major types are the macular, papular, nodular types. Amyloidosis cutis dyschromica is a very rare specific type of vitiliginous amyloidosis. A 16 year-old female patient and 22 year-old male patient, siblings, referred to the hospital with the complaint of non-pruritic diffuse hyperpigmentation beginning from trunk and spreading to all body. The histopathologic findings and crystal violet stain were consistent with amyloidosis cutis dyschromica. All other investigations were normal. There are few reported cases related with this amyloidosis type and it was seldom reported as familial. This case is the first familial case from Turkey.
