A wild-caught subadult eastern yellowbelly racer (Coluber constrictor flaviventris) presented with three raised, circumscribed, freely moveable subcutaneous masses over the dorsal and right epaxial musculature. Microscopic examination and special staining of surgically excised masses were diagnostic for chromatophoroma. No metastases were apparent on whole-body plain film radiographs and computed tomography. Additional excisional biopsies of previously affected sites performed 13 wk later demonstrated normal skin and subcutis. The snake recovered uneventfully and continued to do well 18 mo later. Surgical excision of chromatophoromas remains the treatment of choice in snakes. Subcutaneous masses in snakes should be thoroughly investigated.
一条野生捕获的亚成年东部黄腹游蛇（Coluber constrictor flaviventris）在背部和右侧轴上肌肉处出现了三个凸起的、边界清晰的、可自由移动的皮下肿块。对手术切除肿块进行显微镜检查和特殊染色诊断为色素细胞瘤。全身平片和计算机断层扫描未发现转移迹象。13周后对先前受影响部位进行的额外切除活检显示皮肤和皮下组织正常。这条蛇顺利康复，18个月后状况依然良好。色素细胞瘤的手术切除仍是蛇类的首选治疗方法。蛇身上的皮下肿块应进行彻底检查。
