An acral fibrochondromyxoid tumor is a newly described type of benign soft tissue neoplasm that presents as a single nodular lesion on a finger or toe. There has only been one previous report on this tumor, a case series that described the initial pathologic and clinical findings; however, details on clinical history, physical examination, and outcome are unknown. In this report, we describe a case of a 39-year-old male who presented with a painful enlarging mass involving the distal right 3rd finger and hyponychium. Punch biopsy was performed and the lesion was identified as an acral fibrochondromyxoid tumor on microscopic examination. X-ray showed no bony involvement. The tumor was successfully excised with complete resolution of pain symptoms. We discuss the clinical features and immunohistochemistry findings of our case in the context of the current limited knowledge about this very rare tumor.
肢端纤维软骨黏液样肿瘤是一种新描述的良性软组织肿瘤，表现为手指或脚趾上的单个结节性病变。此前仅有一篇关于该肿瘤的报道，是一个病例系列，描述了最初的病理和临床发现；然而，临床病史、体格检查及预后的细节尚不清楚。在本报告中，我们描述了一例39岁男性，其右手中指远端及甲下出现一个疼痛性增大的肿块。进行了穿刺活检，显微镜检查显示该病变为肢端纤维软骨黏液样肿瘤。X线检查未发现骨质受累。肿瘤成功切除，疼痛症状完全缓解。我们结合目前对这种非常罕见肿瘤的有限认识，讨论了我们病例的临床特征和免疫组化结果。
