We report on a 57-year-old patient presenting with progressive malaise, joint pain and skin rashes one month after visiting Costa Rica. After exclusion of common tropical diseases empiric antibiotic therapy was initiated, however, the patient's symptoms did not improve.
CT scan of the chest demonstrated an intrapulmonary nodular lesion. Bronchoscopy revealed no pathological changes. Microbiologic analysis of the bronchoalveolar lavage fluids identified no pathogen. An abdominal ultrasound examination did not reveal pathological findings. Serological tests were positive for Histoplasma capsulatum.
Treatment with itraconazole resulted in a fast initial clinical improvement, but complete resolution of all symptoms only occurred after completion of a 6-months course of itraconazole. Serial CT scans demonstrated a continuous regression of the pulmonary lesion.
Histoplasmosis has a low incidence among travelers. However, histoplasmosis should be considered in patients with respiratory symptoms and history of travel to endemic countries, specifically when common traveler diseases have been excluded. Diagnosis is confirmed by serology, imaging and ultimately by biopsy for histological, cultural and molecular identification of the pathogen. Antimycotic drug therapy is the recommended treatment of choice for symptomatic cases.
我们报告一例57岁患者,在访问哥斯达黎加1个月后出现进行性不适、关节疼痛和皮疹。在排除常见热带疾病后开始经验性抗生素治疗,但患者症状未改善。
胸部CT扫描显示肺内结节性病变。支气管镜检查未发现病理变化。支气管肺泡灌洗液体的微生物学分析未发现病原体。腹部超声检查未发现病理结果。组织胞浆菌血清学检测呈阳性。
伊曲康唑治疗初期临床症状迅速改善,但所有症状在完成6个月伊曲康唑疗程后才完全缓解。系列CT扫描显示肺部病变持续消退。
组织胞浆菌病在旅行者中发病率较低。然而,有呼吸道症状且有前往流行国家旅行史的患者应考虑患组织胞浆菌病的可能,特别是在排除常见旅行者疾病之后。通过血清学、影像学检查,最终通过活检进行病原体的组织学、培养和分子鉴定来确诊。抗真菌药物治疗是有症状病例的推荐治疗方法。
