The term "myiasis" refers to the parasitic infestation by fly maggots in human tissue. Although cutaneous involvement is well documented, anorectal myiasis is exceedingly rare, particularly when caused by , The New World screwworm fly. We present the case of a 55-year-old male septic tank worker from a rural northern community of Honduras. The patient presented with hyperglycemia, perianal pain, discharge, and prolapsed hemorrhoids. Upon admission, an early evaluation led to a new diagnosis of diabetes type II. We arranged a surgical exploration in the operating theater under general anesthesia. During debridement and exploration, we found numerous larvas invading the anal mucosa and second-/third-degree hemorrhoids. The treatment included submucosal hemorrhoidectomy, larval extraction, systemic antibiotics, outpatient wound care, glycemic control, and a dose of ivermectin, all of which led to a full recovery. This case highlights the diagnostic and therapeutic challenges of myiasis in atypical anatomical sites, impaired wound healing in diabetic patients, and emphasizes occupational risk in low-sanitation environments.
“蝇蛆病”一词指蝇蛆在人体组织中的寄生感染。虽然皮肤受累已有充分记录，但肛门直肠蝇蛆病极为罕见，尤其是由新大陆螺旋蝇引起时。我们报告一例来自洪都拉斯北部农村社区的55岁男性化粪池工人的病例。患者表现为高血糖、肛周疼痛、分泌物及内痔脱垂。入院时，早期评估得出新诊断为II型糖尿病。我们安排在全身麻醉下于手术室进行手术探查。在清创和探查过程中，我们发现大量幼虫侵入肛门黏膜及二度/三度内痔。治疗包括黏膜下痔切除术、幼虫取出、全身使用抗生素、门诊伤口护理、血糖控制以及一剂伊维菌素，所有这些措施使患者完全康复。该病例凸显了非典型解剖部位蝇蛆病的诊断和治疗挑战、糖尿病患者伤口愈合受损，并强调了低卫生环境中的职业风险。
