Bullous and pustular cutaneous larva migrans: two case reports and a literature review

Abstract

AbstractsCutaneous larva migrans (CLM) is a common skin infestation in tropical countries. The classic presentation is a serpiginous, migratory track on the feet. Local and systemic reactions, as well as secondary bacterial infections, are rarely reported. The authors report two cases of CLM with a blister and pustular response on uncommon body locations. The patients were treated with anthelmintic therapy, and a topical corticosteroid was used to relieve their severe reactions. This report aims to describe an infrequent presentation of a common disease and review treatment plans.

Multiple itchy lesions after recent travel

“…CLM is a clinical diagnosis, presenting as pruritic serpiginous tracks that migrate 1-2 cm daily. Vesiculobullous lesions occur in 9-15% of cases and sometimes reach a large size (several centimetres in diameter) 234. Bacterial superinfection is possible (9-24% of cases in Brazil), commonly as a result of lesions being scratched 1…”

Bullous cutaneous larva migrans: an atypical case of creeping eruption

“…CLM is an endemic tropical disease caused mainly by the filariform strongyloid third-stage of Ancylostoma caninum, Ancylostoma braziliensis and Uncinaria stenocephala 6 . Skin manifestations of CLM are typically characterized by linear or snake-like, migratory eruptions, and may be pruritic, painless, or painful 5 . The swelling lesions caused by hookwormrelated cutaneous larva migrans subcutaneous can be mistaken by herpes zoster, scabies, loiasis, myiasis, cercarial dermatitis (schistosomiasis), tinea corporis, contact dermatitis, and myasis.…”

“…Generally, anthelmintic treatment (as oral albendazole or ivermectin, and topical thiabendazole) can reduce the symptoms and abbreviate the extent of disease without any development of complications 2,5 .…”

“…Occasionally, atypical presentations of CLM involves the development of blistering (Bullous cutaneous larva migrans -BCLM) and/or pustular (Pustular cutaneous larva migrans -PCLM) lesions 5 . Here a case of BCLM on a 2-year-old child is report.…”

Larva migrans cutanea – eine wichtige Blickdiagnose bei Reiserückkehrern

“…Hierbei sind die serpiginösen, erythematösen Gänge pathognomonisch; eine positive Reiseanamnese in endemische Gebiete und Kontakt zu potenziell infestiertem Boden, wie einem urbanen Strand stärken den Verdacht [1]. In seltenen Fällen kann es auch zu einer abweichenden klinischen Präsentation mit Blasen und Eiter kommen [8]. Klinisch kann vor allem bei einem ausgeprägten Mehrfachbefall wie dem hier beschriebenen Kasus, die Diagnose erschwert sein.…”
