Dermatofibrosarcoma protuberans is a low-grade cutaneous sarcoma typically located on the trunk or proximal extremities. Less common locations include the head, face, and neck area. This tumour is slow growing with variable clinical appearance. It is known for its locally invasive nature and low metastatic propensity. Because imaging findings are rather nonspecific, biopsy is needed for definite diagnosis. This case describes an unusually large example of dermatofibrosarcoma protuberans in the less common preauricular region.
隆突性皮肤纤维肉瘤是一种低度恶性的皮肤肉瘤，通常位于躯干或四肢近端。较少见的部位包括头、面和颈部区域。这种肿瘤生长缓慢，临床表现多样。它以局部侵袭性和低转移倾向而闻名。由于影像学表现相当不具特异性，因此需要进行活检以明确诊断。本病例描述了一例罕见的位于耳前区域的巨大隆突性皮肤纤维肉瘤。
