Dermatofibrosarcoma Protuberance of Male Breast: A Rare Case Presentation

We report a case of a 50-year-old man who is a chronic smoker, referred to our IBCC (Integrated Breast Care Centre) department, in AIIMS, Rishikesh with complaints of a lump in his left breast for 6 years. A 3×2 cm, ill-defined, firm to hard, non-mobile lump located in the upper and outer quadrant of the left breast which is beneath the previous surgical scar with skin infiltration is noted. Histological characteristics of DFSP are the arrangement of monomorphic spindle cells in a storiform pattern. It was staged as T4b N0 M0 and left wide local excisional biopsy of the tumor with a macroscopically free margin of 3 cm and sent for frozen section which revealed a dendritic differentiation with free margins and further confirmed on final histopathological examination. The postoperative recovery of the patient was uneventful. No loco-regional recurrence or distant metastasis was noted for 6 months of regular follow-up.
