Macular amyloidosis is a form of cutaneous amyloidosis characterized by dusky-brown lesions usually located on the upper back between the shoulder blades. This report describes the case of a 45-year-old female presenting with hyperpigmented macules and lace-like, non-pruritic erythema in the sacral and cervical region as well as on both arms and legs. Histology revealed amyloid deposits in the papillary dermis which exhibited apple-green birefringence after Congo red staining. There were no systemic findings. This is a case of macular amyloidosis with an unusual presentation. The literature on the subject is also reviewed. Keywords: Amyloidosis; Congo Red; Hyperpigmentation Resumo: A amiloidose macular é uma forma cutânea primária de amiloidose, caracterizada tipicamente por máculas acastanhadas, acometendo predominantemente a região interescapular. O presente caso é o de uma mulher de 45 anos, há um ano com manchas hipercrômicas, rendilhadas e não pruriginosas, em membros superiores, região cervical, sacral e membros inferiores. No estudo histopatológico da biópsia de pele, foi evidenciada substância amiloide amorfa no topo das papilas dérmicas, que se tornou mais evidente após a coloração pelo vermelho Congo. Não havia alterações sistêmicas associadas. Além da localização atípica e extensa da amiloidose cutânea macular, o presente caso procura acrescentar dados para esclarecimento do tema.
