Cutaneous involvement has not been recognized as a clinical feature of secondary systemic amyloidosis. Yet in one publication it was described in eight out of nine patients with amyloidosis complicating rheumatoid arthritis.1 It is of interest to note that a considerable number of chronic dermatoses may be associated with the development of secondary amyloidosis including psoriasis, lepromatous leprosy, hidradenitis suppurativa, chronically infected burns, and dystrophic epidermolysis bullosa.2โ4 In patients with no cutaneous lesions and symptoms suggestive of systemic amyloidosis, the diagnosis can be confirmed by Congo red staining of abdominal fat fine-needle aspirates or biopsies.5โ10 Most studies have shown
