Introduction: The secretory breast carcinoma is very rare in children. It represents less than 1% of malignancy cases in childhood and is even less common in males, with 15 cases reported until 2004. Therefore, the aim of this study is to report a male child with breast carcinoma and review literature.
Presentation of case: A 14-year-old male patient with a history of a painless slow-growing lump in the left breast and, five years later, onset of yellow discharge from the papilla. Ultrasound scanning demonstrated a well- defined, regular, homogeneous and hypoechoic mass. Nodule excision was initially performed, followed by mastectomy, due to compromised radial margin. Immunohistochemistry revealed weakly positive estrogen and progesterone receptors. Adjuvant therapy was not required. Sixteen months after resection, the patient is well with no complaints or recurrence.
Discussion: Due to its rarity, there is no therapeutic guideline. Although the recommended treatment is still surgical excision, there is no consensus as to its extent. Prognosis is usually favorable. Our patient was submitted to mastectomy with sentinel lymph node biopsy due to compromised radial margin.
Conclusion: Secretory breast carcinoma is a rare form of breast cancer, especially in male children; which hampers standardization of diagnosis, treatment and prognosis establishment.
