Key result
MRI effectively delineates tumor extent and atypical cystic changes in dermatofibrosarcoma protuberans.
Why the study?
Magnetic resonance imaging features of dermatofibrosarcoma protuberans (DFSP) are not well characterized to guide surgeons in diagnosis and management.

Deep DFSP without dermal involvement warrants diagnostic consideration; leaves open optimal management strategies pending larger series.
SUMMARY: Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing, spindle cell neoplasm with low to intermediate grade malignant potential, commonly found in young and middle-aged adults, more in males than females. DFSP mostly originates in the dermis; rarely, it may be located in the deeper tissues without dermal involvement. Typically, DFSP appears as a multinodular mass, which then spreads into the subcutaneous tissues and muscle; it rarely dedifferentiates to high-grade fibrosarcoma, and more rarely, it may metastasise. We describe magnetic resonance imaging (MRI) features in three female patients with histologically proven DFSP and review the literature.

Sitela et al. (2021) conducted a case report in Dermatofibrosarcoma protuberans (n=3). Magnetic resonance imaging was evaluated on MRI features and tumor extent. Magnetic resonance imaging effectively delineated tumor extent and depth in three patients with dermatofibrosarcoma protuberans, revealing both typical features and atypical presentations such as cystic changes.
