A 34-year-old woman with no known medical history was evaluated for multiple painful brown nodules and papules on the anterior aspect of the trunk. She mentioned a history of similar cutaneous findings on her mother. Biopsies of three lesions revealed piloleiomyomata. Renal and adrenal ultrasound revealed an isolated simple cortical cyst, and pelvic and endovaginal ultrasound revealed two uterine myomata. The clinical diagnosis of hereditary leiomyomatosis and renal cell cancer was corroborated by the identification of a heterozygous variant on exon 5 of the fumarate hydratase gene (c.578C>T p.T193I). Identification of the tumor piloleiomyoma should alert the dermatologist to this rare genodermatosis, which is associated with an increased risk of renal cell tumors, demanding multidisciplinary follow-up, and personal and family counseling.Uma mulher de 34 anos sem antecedentes patológicos conhecidos foi avaliada por apresentar múltiplos nódulos e pápulas castanhos, dolorosos, na face anterior do tronco. Referia história de achados cutâneos semelhantes na sua mãe. As biópsias de três lesões revelaram piloleiomiomas. As ecografias renal e suprarenal identificaram apenas cisto renal cortical simples, e as ecografias endovaginal e pélvica, dois miomas uterinos. O diagnóstico clínico de leiomiomatose herediária e câncer de células renais foi corroborado pela identificação de variante heterozigota no exon 5 do gene da Fumarato hidratase (c.578C>T p.T193I). O piloleimomioma é um tumor cuja identificação deve alertar o dermatologista para esta rara genodermatose, associada a um risco aumentado de tumores de células renais, exigindo seguimento multidisciplinar e aconselhamento pessoal e familiar.
