Aspergillus spp. are widely distributed throughout the environment. They are opportunistic pathogens causing infection at various sites in the body such as lungs, sinuses, eyes, skin, central nervous system etc., Primary cutaneous aspergillosis is an uncommon disease entity. Primary infections usually occur at sites having disruption of the skin and usually occur in burn patients, trauma and surgical patients. A 4-year-old girl who was run over by a truck and suffered extensive de-gloving injury to bilateral lower limbs developed greenish discharge and scaly lesions around the wound margins after 50 days of hospital stay. The skin biopsy demonstrated the presence of thin septate hyphae branching at acute angles and culture demonstrated growth of Aspergillus flavus and Aspergillus terreus. The child was started on voriconazole therapy for 3 weeks and the lesion healed satisfactorily. Subsequent skin biopsy culture was negative for fungi. Prompt diagnosis and management of such cases can salvage the limbs in severe trauma cases.
曲霉属广泛分布于整个环境中。它们是机会性病原体,可在身体的各个部位引起感染,如肺部、鼻窦、眼睛、皮肤、中枢神经系统等。原发性皮肤曲霉病是一种罕见的疾病实体。原发性感染通常发生在皮肤有破损的部位,常见于烧伤患者、外伤患者和外科手术患者。一名4岁女童被卡车碾压,双侧下肢遭受大面积脱套伤,住院50天后伤口边缘出现绿色分泌物和鳞屑性病变。皮肤活检显示存在呈锐角分支的细分隔菌丝,培养显示有黄曲霉和土曲霉生长。该患儿开始接受伏立康唑治疗3周,病变愈合良好。随后的皮肤活检培养真菌结果为阴性。对此类病例进行及时诊断和处理可在严重创伤病例中挽救肢体。
