Phyllodes tumors are breast tumors accounting for about 1% of all breast neoplasms in women and are rare in males. Reported here is a case of a 45-year-old male presenting with a rapidly enlarging right breast mass with invasion of the anterior chest wall. Core Needle Biopsy revealed Malignant Phyllodes Tumor. He underwent wide excision and chest wall resection. Reconstruction was performed using polyropelene mesh, a latissimus dorsi flap and split thickness skin grafting. Patient was discharged on the 33rd post-operative day due to delayed expansion of the right lung from splinting and subsequent near-complete loss of the split thickness skin graft over the latissimus muscle flap. On the recommendation of the plastic surgeon, the wound was allowed to heal by secondary intention. This report draws attention to the rarity of malignant phyllodes tumor in males, and the difficulty of recognizing a malignant pathology in males presenting with breast mass. It also highlights a cost-effective treatment option in the management of these tumors.
