Abstract
Breast cancer is a public health problem with an annual incidence exceeding two million new cases leading to its classification as first cancer in women. Its clinical presentation is variable and the palpation of a breast nodule allows the diagnosis to be suspected in the majority of cases. The treatment is multidisciplinary and has health, economic, and psychological impacts. We report a sporadic case of a 60-year-old woman followed for epigastralgia for three months. The current history of the present disease goes back to three days before her admission with the onset of several episodes of hematemesis motivating the patient to consult the ER and then get admitted to the ER for hematemesis. The initial clinical examination showed an epigastric sensitivity in a hemodynamically stable patient. The endoscopy revealed a gastric tumor and immunohistochemistry confirmed the gastric localization from a breast cancer unrecognized by the patient and discovered at the careful clinical examination after having stabilized the patient's condition.
