Abstract: Clouston syndrome is a rare genodermatosis that affects skin and annexes. It is a form of ectodermal dysplasia characterized by generalized hypotrichosis, palmoplantar hyperkeratosis and nail dystrophy. This paper reports a 25-year follow-up of a patient with Clouston syndrome, from childhood to adulthood, monitoring diagnosis and clinical course of the disease.

Relatamos um caso de uma paciente de 48 anos com amiloidose sistêmica associada a mieloma múltiplo. Lesões infiltrativas cutâneas como pápulas, nódulos ou placas com aspecto sero-hemorrágico podem ser localizados nas pálpebras, pescoço, região retroauricular dentre outras. No presente caso, as pálpebras foram acometidas por pápulas, há 1 ano, de caráter intermitente e piora após trauma local. Biópsia local evidenciou material amorfo e eosinofílico na derme. A coloração vermelho do Congo confirmou presença de substância amiloide. Exames anormais: proteinúria de 570mg/24 horas, proteinúria de Bence-Jones positiva e mielograma com 70% de plasmócitos atípicos. Assim, realizou-se o diagnóstico de mieloma múltiplo a partir de manifestações cutâneas de amiloidose. Paciente encaminhada ao serviço de hematologia e foi a óbito em 5 meses.

This case report is about a 48-year-old female patient with systemic amyloidosis and multiple myeloma simultaneously. Amyloid cutaneous infiltrative lesions like papules, nodules, or plaques with a serous-hemorrhagic aspect were found in the eyelids, neck and retroauricular region, among others. She had presented intermittent papular lesions on the upper eyelids one year before, which worsened following local trauma. A local skin biopsy showed amorphous and eosinophilic substance in the dermis. Congo red staining confirmed the amyloid deposits. Abnormal exams: proteinuria (570mg/24h), Bence-Jones proteinuria and clonal plasma cells (70%) found in myelogram. Following the diagnosis of multiple myeloma based on amyloid skin lesions, the patient was referred to the Hematology service and died 5 months after the diagnosis.
