Dellê Urban, Alexandre Bossmann Romanus, Rodrigo Peres Pimenta, Michelle Gusmão de Assis and Karla Alessandra Ferrari RHCFAP/3058 KANEGUSUKU MS et al. - Recurrent spontaneous breast hematoma: report of a case and review of the literature. Rev. Hosp. Clín. Fac. Med. S. Paulo 56(6):179-182, 2001. Background: Breast hematomas are common after traumas, surgeries, or contusions. They are rarely spontaneous, but they can occur spontaneously in patients with hematologic disease or with coagulation disorders. Material and methods: The authors report a clinical case of a 48-year-old female with a 27-year history of paroxysmal nocturnal hemoglobinuria who underwent mammography screening because of a painless palpable moveable node in the upper inner quadrant of the right breast. Results: Mammography showed a partially defined heterogeneous node of 35 mm without microcalcifications in the upper inner quadrant of the right breast which, associated with the clinical features, seemed to be an hematoma. Further mammography and ultrasound after 45 days showed retrocession of the lesion, and another mammography obtained after 60 days was normal. Seventy-five days after the first episode, the patient complained of another node with a skin bruise in the upper outer quadrant of the same breast, which seemed to be a recurrent hematoma. Two months later the mammography obtained was normal. Conclusion: Breast hematoma must be thought of as a differential diagnosis for a breast node, regardless of previous trauma or hematologic disorders. DESCRIPTORS: Breast. Hematoma.
