A benign posttraumatic spindle cell proliferation arising at a site of laceration in the buccal mucosa of a 19-year old man is described. This lesion, which histologically mimicked a leiomyosarcoma, appears to represent a reactive process similar to that described as postoperative spindle cell nodules of the genitourinary tract. Reexcision of the area 1 month after biopsy revealed only scar formation and mild chronic inflammation. Recognition of this type of benign spindle cell proliferation at traumatized sites in the oral cavity is important if misdiagnosis and subsequent aggressive therapy is to be avoided.
描述了一名19岁男性颊黏膜撕裂部位出现的良性创伤后梭形细胞增生。该病变在组织学上类似平滑肌肉瘤，似乎代表一种类似于泌尿生殖道术后梭形细胞结节所描述的反应性过程。活检后1个月对该区域再次切除，仅见瘢痕形成和轻度慢性炎症。如果要避免误诊和后续的积极治疗，认识口腔创伤部位的这种良性梭形细胞增生很重要。
