Two cases of subungual myiasis in predisposed patients

Myiasis of open great toe fracture wound: a rare case report

Introduction and importance

Myiasis of an open fracture wound is very rare but can occur due to neglect of wound care.

Case presentation

A 12-year-old boy from a low socio-economic background, following an impact injury in his right great toe 10 days back presented with complaints of pain, swelling, and a foul-smelling odor from his right great toe. On examination, a swollen, tender puncture wound was noted over the dorsal aspect of the great toe revealing part of live larvae and serosanguinous discharge. Management was done with the complete removal of maggots, wound debridement, wound lavage, administration of systemic antibiotics, and toe guard slab application.

Clinical discussion

Wound myiasis results from a facultative or obligatory parasite that is initiated when flies oviposit in hemorrhagic, necrotic, or pus-filled lesions. The possible complications of myiasis include local destruction, invasion into deep tissues, and secondary infection, which could result in amputation of the affected area, especially where obligatory parasites are concerned.

Conclusion

Myiasis commonly occurs due to poor hygiene and neglect of wound care along with many other risk factors. Early proper wound care prevents the development of wound myiasis and early diagnosis and treatment of myiasis prevent complication of local tissue destruction and amputation of affected parts.

Ingrown nail with subungual myiasis on the same toe: A rare case presentation

We report an extremely rare case of an ingrown nail with subungual myiasis on the same toe (was documented with videos) in a female patient with no previous history of travel, trauma, contact with animals, immunosuppressive treatment, or psychiatric disorders.

Parasites causing cutaneous wounds: Theory and practice from a dermatological point of view

A wide range of parasites can infest open wounds, or cause wounds due to the effects of the infestation. Parasitic infestations can involve the skin and subcutaneous tissues, with various clinical manifestations. In case of cutaneous wounds related to infestations, protozoa, helminths and arthropods are the main groups of parasites involved and emerging new aspects have been recently reported. Treating the wound correctly is fundamental in these patients in order to reduce the development of pathological scars and prevent complications. In particular, a gentle debridement for devitalized/infested tissue removal, the appropriate use of topical antiseptics and dressings such as hydrogel, hydrocolloids and antimicrobial dressings can be useful to control superinfections, moisture balance, inflammation and to promote edge proliferation.
