A 61-year-old immunosuppressed renal transplant patient with inflammatory bowel disease presented with tender pink nodules on the trunk and extremities. An initial biopsy was suggestive of metastatic Crohn disease, but after disease persistence, a second biopsy revealed disseminated Mycobacterium haemophilum. Atypical mycobacterial infections should be considered in immunosuppressed patients. This case highlights the complexities of diagnosing such infections in patients with an underlying granulomatous condition and the particular growth requirements of M. haemophilum.
一名61岁的免疫抑制肾移植患者，患有炎症性肠病，躯干和四肢出现压痛性粉红色结节。初次活检提示为转移性克罗恩病，但病情持续存在后，二次活检显示为播散性嗜血性分枝杆菌。免疫抑制患者应考虑非典型分枝杆菌感染。该病例凸显了在患有潜在肉芽肿性疾病的患者中诊断此类感染的复杂性以及嗜血性分枝杆菌特殊的生长需求。
