ABSTRACT
The myofibroblastoma of the breast is rare, being even less frequent in women. It is a benign mesenchymal tumor of uncertain etiology. The present study reports the case of a 47-year-old patient with a palpable nodule on the right breast, non-painful, having appeared approximately one year before, and with slow growth, located in an inferolateral quadrant. The biopsy pathology product describes a firm, yellowish white tissue that microscopically exhibited fusocellular proliferation without atypia, including small ductal structures with epithelial hyperplasia, suggesting immunohistochemistry which revealed expression of desmin and smooth muscle actin. Based on the morphological and anatomopathological picture, the diagnosis of breast myofibroblastoma was confirmed. Sectorectomy surgery was performed as treatment
RESUMO
O miofibroblastoma de mama é raro, sendo menos frequente ainda em mulheres. Trata-se de um tumor mesenquimal benigno de etiologia incerta. A presente descrição relata o caso de uma paciente de 47 anos, apresentando um nódulo palpável na mama direita, não doloroso, com surgimento há aproximadamente um ano e de crescimento lento, localizado em quadrante ínferolateral. O anatomopatológico de biópsia produto de core biopsy descreve tecido branco amarelado, de consistência firme, que microscopicamente apresenta proliferação fusocelular sem atipias, incluindo pequenas estruturas ductais com hiperplasia epitelial, sugerindo imuno-histoquímica, a qual revelou expressão de desmina e actina de músculo liso. Com base no quadro morfológico e anatomopatológico, confirmou-se o diagnóstico de miofibroblastoma de mama. Foi realizada setorectomia como tratamento
