RESUMO
Introduction: Breast angiosarcoma is a rare, aggressive tumour affecting adult women. It can occur in two forms, primary form and secondary forms or radiation-induced breast angiosarcoma affecting patients with history of breast or chest radiotherapy. Case presentation: The authors report a new case of breast angiosarcoma in 52-year-old women, with history of invasive ductal carcinoma, and reporting a discoloration of her breast skin. The patient did undergo a mastectomy of right breast and adjuvant chemotherapy. Conclusion/discussion: Surgery with total excision associated or not to adjuvant chemotherapy remains the treatment of choice in breast angiosarcoma.
RESUMO
INTRODUCTION: Extra-gastrointestinal stromal tumors (EGISTs) are rare mesenchymal tumors located outside the gastrointestinal tract, and exhibit the same phenotypic and morphological profile of gastrointestinal stromal tumors (GISTs). CASE REPORT: We report the case of a 20-year-old male patient consulted for chronic discomfort in the hypogastric region. Abdominal ultrasound and abdomino-pelvic CT scan identified a retro-vesical mass measuring 16 × 9 cm. He underwent an exploratory laparotomy and a total resection of the mass R0. The histopathological panel of the surgical specimen confirmed the diagnosis of EGIST. CLINICAL DISCUSSION: The primary localization in the recto-vesical pouch of EGIST is a very rare entity. Their clinical and radiological presentations are unusual, and their definitive diagnosis is largely based on immunohistochemistry staining. CONCLUSION: the origin of extra gastrointestinal stromal tumors EGIST can remain unclear.
