RESUMO
Los sarcomas suponen menos del 1% de los tumores malignos de la mama. Presentamos un caso de sarcoma (histiocitoma fibroso maligno) de mama que debuta en forma de tumoración, que la paciente relaciona con un traumatismo, y que mostró un aspecto clínico, ecográfico y citológico sugestivo de un hematoma. La tumoración creció rápidamente, y en la ecografía de control realizada al mes tenía claros polos sólidos hipervasculares. Es una presentación atípica, que permite revisar el manejo de lesiones sugestivas de hematomas, y que, en su evolución, a menudo se asocian a imágenes inespecíficas, en ocasiones sospechosas de malignidad. La aparición de lo que parece un hematoma mamario, incluso acompañado de un antecedente traumático o tendencia al sangrado, obliga a ser prudentes, por lo que se recomienda un seguimiento a muy corto plazo, y biopsia, incluso excisional, si los hallazgos evolutivos no son concordantes
Sarcomas account for less than 1% of malignant breast tumors. We present the case of a sarcoma (malignant fibrous histiocytoma) of the breast that debuted as a lump. The patient associated the lump with trauma, and the clinical, sonographic, and cytological findings were suggestive of a hematoma. The lump grew rapidly, and the follow-up sonogram one month later clearly revealed hypervascular solid poles. This atypical presentation is useful for reviewing the management of lesions suggestive of hematomas, which are often associated with nonspecific findings and occasionally with signs that raise suspicion of malignancy. The emergence of what appears to be a hematoma in the breast, even when accompanied by a history of trauma or a tendency toward bleeding, calls for prudence: very short-term follow-up and biopsy, even excisional biopsy, are recommended if the lesion does not evolve like a hematoma
