Amyloid deposition can be localized or systemic and either primary or secon-dary. We report a case of localized primary cutaneous nodular amyloidosis manifested by papular-nodu-lar, reddish-brown lesions affecting the nasal area, without evidence of systemic involvement.Immunohistochemistry showed the presence of immunoglobulin kappa light chain.Keywords: Amyloidosis; Plasma cells; Skin Recebido em 17.07.2010.Aprovado pelo Conselho Consultivo e aceito para publicacao em 26.08.2010. * Trabalho realizado na Fundacao de Dermatologia Tropical e Venereologia Alfredo da Matta (Fuam) – Manaus (AM), Brasil.Conflito de interesse: Nenhum / Conflict of interest: None Suporte financeiro: Nenhum / Financial funding: None 1 Medico(a) residente em dermatologia da Fundacao Alfredo da Matta (Fuam) – Manaus (AM), Brasil. 2 Mestre em patologia tropical pela Universidade Federal do Amazonas (Ufam); medico dermatologista; preceptor da residencia medica em dermatologia da Fundacao Alfredo da Matta (Fuam) – Manaus (AM), Brasil.
