B87.1
Wound myiasis
Clinical Classification Guidelines
Inclusion Terms
- Traumatic myiasis
Medical Intelligence & Overview
Wound myiasis, classified under ICD-10 code B87.1, is a parasitic infestation involving the invasion of open wounds by fly larvae, commonly known as maggots. This condition, sometimes called traumatic myiasis, occurs when certain fly species lay eggs in wounds or necrotic tissue, leading to larval development that can complicate healing and cause additional tissue damage. Recognizing the signs and understanding how it occurs are crucial for effective management and prevention.
Causes & Symptoms
Clinical Causes: Infection by specific fly species, such as the botfly (Dermatobia hominis) or blowflies (Calliphoridae family), which lay eggs on wounded or decaying tissue. Presence of open wounds, ulcers, or necrotic tissue that provide an attractive environment for egg deposition. Poor hygiene or inadequate wound care, increasing the risk of fly contact and oviposition. Harsh environmental conditions or living in areas where these flies are prevalent, such as tropical or subtropical regions. Limited mobility or inability to maintain proper wound hygiene due to underlying health conditions.
Key Symptoms: Visible movement or presence of maggots in the wound. Severe itching or discomfort at the infestation site. Swelling, redness, or inflammation surrounding the wound. Foul odor emanating from the wound area. Increased pain and possible tissue destruction if the infestation progresses. Secondary bacterial infection signs, such as pus or increased swelling. Skin discoloration around the wound border.
Diagnostic & Treatment
Diagnosis Path: Diagnosing wound myiasis involves a physical examination of the affected area, often revealing live larvae within the wound. Healthcare providers may gently extract visible maggots for identification. Additional diagnostic steps include:
Treatment Protocols: Managing wound myiasis generally requires prompt removal of all maggots and treating the wound to promote healing. Typical approaches include:
