Clear cell sarcoma (CCS) is a rare malignant soft tissue tumor originating from neural crest cells. Histologically resembling malignant melanoma but lacking cutaneous precursor lesions, CCS is characterized by a specific chromosomal translocation (t[12;22][q13;q12]). Primarily affecting young adults, this tumor typically arises in the extremities, especially the knee, foot, and ankle. To our knowledge, distal toe involvement is uncommon. Herein, we present a case initially diagnosed on magnetic resonance imaging as a superficial soft tissue tumor resembling malignant melanoma but subsequently confirmed as CCS of the great toe.
透明细胞肉瘤（CCS）是一种起源于神经嵴细胞的罕见恶性软组织肿瘤。在组织学上类似于恶性黑色素瘤，但缺乏皮肤前驱病变，CCS的特征是特定的染色体易位（t[12;22][q13;q12]）。该肿瘤主要影响年轻人，通常发生在四肢，尤其是膝盖、足部和脚踝。据我们所知，远端趾受累并不常见。在此，我们报告一例最初在磁共振成像上被诊断为类似恶性黑色素瘤的浅表软组织肿瘤，但随后被确诊为拇趾CCS的病例。
