“…In the previous literature, at the time of diagnosis, the majority of patients who had accessory breast cancer were diagnosed at an advanced clinical stage, with unresectable tumor size or nodal metastasis. The prognosis of accessory breast cancer may be worse than breast cancer, although no long-term follow-up data regarding the prognosis of accessory breast cancer is available (Nihon-Yanagi et al, 2011;Yamamura et al, 2012). In several studies, treatment regimens for accessory breast carcinoma followed the guidelines for breast cancer (Kahraman-Cetintas et al, 2008).…”

“…In several studies, treatment regimens for accessory breast carcinoma followed the guidelines for breast cancer (Kahraman-Cetintas et al, 2008). Similar to breast cancer, accessory breast cancer is also surgically treated and supplemented with chemotherapy, radiotherapy, and hormonal therapy (Nguyen et al, 2022). Recently, some scholars have also conducted a systematic analysis of the treatment of male breast cancer.…”

Male accessory breast cancer is an extremely rare tumor. There is no report about its monotherapy and subsequent outcome prior to 2022. The current study presents the case of a 76-year-old male patient with a hard mass in the left axilla. Histopathologic examination of an excisional specimen indicated an adenocarcinoma compatible with breast carcinoma. Immunohistochemical analysis demonstrated that the mass was estrogen receptor (ER) (−), progesterone receptor (PR)(−), and human epidermal growth factor receptor type 2 (HER2) (−). A diagnosis of breast cancer originating from the accessory mammary gland in the axilla was made. Two years following surgery, the patient presented with a pulmonary lesion. Core needle biopsy was performed, and the lesion was found to be ER (−), PR(−), and HER2 (3+). The patient was successfully treated with single-agent trastuzumab. Single-agent trastuzumab could be a reasonable regimen for metastatic accessory breast cancer patients with HER2 overexpression for whom chemotherapy and endocrine therapy are not suitable.

Accessory or ectopic breast tissue is an anomaly in the development of the breast. It is a rare condition that occurs along the embryological mammary line. In less than 1% of all breast cancers, supernumerary breast cancer is reported, with the axillary location being the most common in 60% to 90% of cases. Cancerous degeneration of this supernumerary breast tissue can pose a dual diagnostic and therapeutic problem. We report the case of locally advanced adenocarcinoma in a right supernumerary breast. This is a 75-year-old, grand-multiparous, postmenopausal, and known hypertensive patient on treatment. Family history was remarkable for brain cancer in her sister and oesophageal cancer in her mother. She consulted for a mass in the right axillary cavity on supernumerary breast evolving for a year. Clinical examination revealed a large, fixed, budding and haemorrhagic-ulcerated mass of the right axilla, with long axis measuring about 15 cm. There was as wella supernumerary breast on the left, but without particularity. A soft tissue ultrasound showed a large hypoechoicmass in the right axillary region of 116 mm with areas of central necrobiosis. Morphologically, the breasts were normal. A breast MRI revealed a subcutaneous mass in the right axillary cavity with skin ulceration and satellite lymphadenopathy. The extension assessment revealed liver metastases, and a biopsy of the mass revealed a breast adenocarcinoma. The case was the subject of a multidisciplinary consultation meeting following which a wide excision of the mass was indicated. The histo-pathology analysis results of the surgical specimen were in favour of a triple negative How to cite this paper:
