Abstract:

We report a case of a 42-year-old male chef who presented with a four-month progressive history of left breast swelling accompanied by recent-onset nipple pain and sanguineous discharge. Clinical examination and ultrasonographic imaging suggested benign gynecomastia with duct ectasia. However, histopathological examination of the surgically excised specimen revealed an unexpected diagnosis of invasive ductal carcinoma, Nottingham Grade 1, measuring 1.1 centimetre with extensive intraductal component. Immunohistochemical analysis demonstrated oestrogen receptor and progesterone receptor positivity with human epidermal growth factor receptor 2 negativity, corresponding to pT1N0M0 stage disease. Positron emission tomography imaging excluded distant metastasis. The patient proceeded to modified radical mastectomy with planned adjuvant chemotherapy. This case highlights the critical diagnostic imperative of maintaining elevated clinical suspicion for malignancy in male patients presenting with nipple discharge or atypical breast findings, emphasizes the essential role of tissue diagnosis in establishing pathological certainty, and underscores the importance of multidisciplinary team approach in optimizing treatment outcomes in this rare malignancy.
