“…This is followed by the development of sharp pain, ulcers, oozing fluid, and crusting on the disease base, which is recurrent, difficult to heal, and severe during winter. In addition, the long-term recurrence leaves ivory-white or yellow-white atrophic scars, which are stellate, punctate, or irregular in shape, accompanied by telangiectasia and pigmentation ( 13 ), leading to delayed wound healing, microbial infection, and further development into edema and thrombosis ( 14 ). It is necessary to distinguish AB from allergic vasculitis, cutaneous nodular polyarteritis, and allergic purpura.…”

Atrophie blanche complicated with lower limb infection and maggot growth: A case report

BackgroundAtrophie blanche (AB) is a thrombotic vascular disease, also known as venous vasculitis or segmental hyaline vasculitis, characterized by chronic recurring painful ulcers on the lower legs, especially the ankles. AB is a clinically rare condition, affecting 1%–5% of the population, specifically middle-aged women with an average age of 45 years, and cases of AB in children are rare. Following recovery, ivory-white atrophy spots accompanied by pigmentation and telangiectasia remain in patients. One of the complications of AB is the parasitic growth of microorganisms infecting the ischemic soft tissue undergoing necrosis in the lower limbs. Furthermore, although infection combined with microbial parasitism is a type of surgical site infection, myiasis is particularly rare, which may warrant limb amputation or may even be life-threatening. Understanding the complications of AB may help in early and timely surgical debridement as well as wound repair. Summarizing the knowledge and treatment strategies of AB and formulating clinical strategies and guidelines for AB management with insights from relevant cases are important.Case summaryA 59-year-old woman was hospitalized due to repeated ulceration of the skin of the right lower leg for 3 years, aggravation, and maggot growth for 3 days. In the previous 3 years, the skin and soft tissue of the right calf had become ischemic, necrotic, and infected, but the patient did not seek any medical treatment. Subsequently, 2 years ago, she was diagnosed with AB at the dermatology department of our hospital. After hormone treatment, her right leg improved. However, 1 year ago, the skin and soft tissue of the right leg again became ischemic, necrotic, and infected. This time, the patient did not seek medical treatment and applied musk on her wound. The wound deepened, resulting in the exposure of the tendon and some bones. In addition, a large number of maggots and microorganisms grew in and infested the wound for 3 days before the patient came to our department for treatment. Debridement of the necrotizing infected site on the right lower leg combined with negative pressure vacuum sealing drainage were performed twice within 16 days after admission. Simultaneously, antibiotics were given systemically. On the 17th day after admission, the wound appeared clean, myiasis had resolved, and the growth and coverage of the granulation tissue on the wound were satisfactory. Subsequently, debridement of the infected site on the right leg, removal of skin of the right thigh, and autologous free skin grafting were performed. After 10 days, the wound was clean, all skin grafts had survived, and wound repair was satisfactory. Finally, the patient was discharged after 38 days of hospitalization.ConclusionAlthough AB is rare, leukodystrophy requires specialized treatment and regular follow-up. If lower limb infection and maggot growth occur simultaneously, self-treatment should be avoided and medical attention must be sought immediately. Early implementation of wound debridement and anti-infective treatment combined with wound repair, which should be performed after cleaning the wound, is advised.

Flies and maggots are of medical importance, and it is often necessary to identify them at species level. Conventionally, this is carried out based on morphological features using taxonomic keys. However, identification of maggots based on morphology is difficult and required entomological expertise is often lacking in many clinical settings. Molecular methods can be an alternative to morphology based identification. We explored the utility of mitochondrial COI gene based molecular method, as a tool for identifying field collected maggots in Puducherry, India. Maggots were collected from different locations in Puducherry using rotten fish and kitchen waste as baits and a segment of the COI gene was amplified and phylogenetic analysis was performed. The identified maggots belonged to Sarcophaga peregrina, Hemipyrellia ligurriensand Chrysomya megacephala. We highlight the usefulness of molecular methods in precise identification of maggots in certain settings is highlighted.
