In the hereby described case, a 28-year-old woman presented in our department with huge (18 × 11 × 8 cm) tumor of left breast, 2 weeks after labor. The patient discovered a tumor in 34th week of pregnancy, 6 weeks before labor. Histopatholgic examination of excised tumor revealed the presence of malignant CSP tumor. Simple mastectomy was proposed to patient as a best treatment modality. However, the patient refused. She underwent excision of tumor bed (2-cm tumor-free margin was achieved). Despite insufficient treatment, she remains free of disease 20 months after the wide excision of breast malignancy. It is not known how pregnancy influences prognosis of patients with malignant CSP. Lack of such information prompted us to describe the clinical course of our patient. ER -
