Introduction: Dermatofibrosarcoma protuberans is an extremely rare subtype of soft tissue neoplasm. Although DFSP typically manifests in the trunk and extremities, it rarely occurs in the breast, and is often misdiagnosed as benign or malignant breast lesions. Data regarding DFSP in the breast is scarce in existing literature. Only 13 cases in men have been documented. Here, we present a case diagnosed with breast DFSP in a young male patient who underwent surgical excision at our facility.

Case Report: A 24 years old male patient presented to the surgical clinic complaining of painless right breast lump for 8 months. The patient denied any nipple discharge. No history of hormonal or steroids medications use. Upon examination there was non-tender 1cm mass felt at lower outer quadrant of the right breast, with no changes in the overlying skin. At the contralateral side, the left breast was normal. Bilateral axilla was unremarkable.

Discussion: Dermatofibrosarcoma was first described as progressive recurrent dermatofibroma in 1924 by Darier and Ferrand. Subsequently, in 1925 Hoffmann referred to the disease as dermatofibrosarcoma protuberans DFSP.

Conclusion: Dermato Fibrosarcoma Protuberans (DFSP) of the breast is extremely rare. We reported a rare case of breast DFSP in a male patient discovered after 8 months with unusual presentation as a breast lump and not a skin lesion, with nonspecific radiological features. Due to the rarity of breast DFSP cases, surgeons need to be aware of breast DFSP to avoid misdiagnosis with a benign breast lesion and keep a high index of suspicion in male breast lesions.
