larva migrans

BACKGROUND: Cutaneous larva migrans (CLM) is a helminthic infection found in tropical areas. It is commonly seen in patients in contact with soil contaminated by cat and dog hookworm larvae. CLM manifests as an erythematous, serpiginous, and pruritic cutaneous eruption. We present a case of a 27-year-old female with a serpiginous lesion on the plantar surface of the right foot. METHODS AND RESULTS: The patient was prescribed Albendazole at 400 mg twice a day for three days...

Human infection by Baylisascaris procyonis can result in larva migrans syndromes, which can cause severe neurological sequelae and fatal cases. The raccoon serves as the definitive host of the nematode, harboring adult worms in its intestine and excreting millions of eggs into the environment via its feces. Transmission to paratenic hosts (such as rodents, birds and rabbits) or to humans occurs by accidental ingestion of eggs. The occurrence of B. procyonis in wild raccoons has been reported in several Western European countries...

Visceral larva migrans (VLM) occurs due to migration of the second stage of larvae of nematodes through human viscera. It is an underdiagnosed entity which commonly affects the liver as eosinophilic abscesses and appears as coalescing, conglomerated cavities on imaging. This case report details the sonographic and CT features of an 8 year old female patient with right upper quadrant pain and peripheral eosinophilia on laboratory reports, diagnosed as a case of VLM on biopsy. Imaging of VLM shows overlap with neoplastic lesions and other infective pathologies hence this case aims to highlight the clinical, laboratory, and radiological features to help narrow the differential diagnosis...

Toxocariasis is the parasitic infection caused by the larvae of Toxocara roundworms species: Toxocara canis from dogs and, less frequently, Toxocara cati from cats. The high proportion of asymptomatic cases of toxocariasis and the uncharacteristic clinical manifestations mimicking other medical conditions make diagnosis challenging. The main clinical presentations of toxocariasis are visceral and ocular larva migrans. Migration to the central nervous system (neurotoxocariasis) is rare and can cause meningitis, encephalitis, myelitis, cerebral vasculitis, seizures, headache or asymptomatic CNS infection...

BACKGROUND Ancylostoma spp., including A. duodenale, A. braziliense, A. caninum, and A. ceylanicum, are hookworms that are transmitted from infected soil and by contact with domestic animals and rodent hosts, and can cause systemic disease and cutaneous larva migrans. The objective of this study was to describe the ecoepidemiology of Ancylostoma caninum and Ancylostoma spp. in urban-marginal sectors and in rural sectors located in Ecuador. MATERIAL AND METHODS Through addressed sampling, a total of 498 domestic dogs and 40 synanthropic rodents were analyzed via the following coproparasitic methods: direct, flotation, sedimentation with centrifugation using saline (egg identification), modified Baermann (larval identification), and morphometric methods (confirmation)...

BACKGROUND: The raccoon roundworm, Baylisascaris procyonis, can cause a meningoencephalitis as neural larva migrans which is known in avian species, including rainbow lorikeets in North America, but has not been described in Old World parrots in Germany yet. CASE PRESENTATION: A 2-month-old, male rainbow lorikeet from a zoo in Germany was submitted for necropsy. Prior to death the animal had progressive neurological signs like apathy and torticollis. In the cerebrum a focally extensive severe granulomatous to necrotizing encephalitis with an intralesional larval nematode was diagnosed...

Follicular larva migrans (FLM) is a rare and atypical clinical presentation of hookworm-related cutaneous larva migrans (HrCLM). FLM is characterized clinically by follicular, round, small, erythematous papules that are sometimes topped by vesicles or pustules. These lesions are usually located on the abdomen, back, buttocks and thighs and are accompanied by more or less severe pruritus. Some typical and/or short and fragmented tracks may also be visible. FLM is more resistant to anti-helminthic drugs than classical HrCLM: this is likely due to the deep location of larvae in hair follicles...

INTRODUCTION: Cutaneous larva migrans (CLM) is a dermatitis caused by the invasion and migration of parasitic larvae of hookworms, primarily affecting tropical and subtropical regions. This report presents a case of CLM in a Nepali child and provides an overview of the literature on this condition. CASE REPORT: A 4-year-old boy from a rural area in Nepal presented with a pruritic skin lesion on his left foot, initially misdiagnosed as fungal infection. The lesion gradually expanded, forming a serpiginous erythema, and became intensely pruritic...

Dermatological disorders are among the most common complaints of patients seeking medical assistance after returning from trips to tropical countries. Among exotic dermatoses, one of the frequently encountered diagnoses is Cutaneous Larva Migrans (CLM), primarily caused by the nematodes Ancylostoma braziliense and A. caninum. Cats and dogs, which serve as the definitive hosts for these nematodes, excrete with their stool parasite eggs into the environment, where they transform into larvae. Human infection occurs through the invasive form of the larvae, which penetrate the skin, causing itching and the characteristic serpiginous, slightly raised, and enlarging lesion at the site of invasion...

Cutaneous larva migrans (CLM) is a dermatosis caused by accidental infestation with animal hookworms and is widely distributed in tropical and subtropical regions. Humans become infected when their skin comes into contact with soil contaminated with dog faeces. The filariform larvae penetrate and burrow into human skin, causing a condition known as "creeping eruption". We describe a case, well-documented by photos, of CLM infection in a family of three who returned from Thailand.

This molecular-epidemiological study was conducted in several locations in Cairo and Giza Governorates in domestic cats ( Felis catus ) to detect the most common intestinal helminths in feces and molecularly characterize this nematode. So, three hundred domestic cats were admitted to different clinics around Cairo and Giza Governorates with severe diarrhea, even watery, between January 2023 and April 2023. The ages of the cats ranged from 1 to 2.5 years old. Blood, sera, and urine samples were collected for further investigation of the health condition of the animals ...

The raccoon roundworm (Baylisascaris procyonis), a gastrointestinal nematode of the raccoon (Procyon lotor), may cause a severe form of larva migrans in humans, which can lead to death or permanent neurological damage. Although roundworms were inadvertently introduced to Europe alongside their raccoon hosts, the parasite is not present in every raccoon population. It is important to understand the geographic distribution of B. procyonis, as early and rapid treatment can prevent severe pathologies in humans...

Toxocariasis remains an important neglected parasitic infection representing one of the most common zoonotic infections caused by the parasite Toxocara canis or, less frequently, by Toxocara cati . The epidemiology of the disease is complex due to its transmission route by accidental ingestion of embryonated Toxocara eggs or larvae from tissues from domestic or wild paratenic hosts. Even though the World Health Organization and Centers for Disease Control classified toxocariasis amongst the top six parasitic infections of priority to public health, global epidemiological data regarding the relationship between seropositivity and toxocariasis is limited...

Cutaneous larva migrans (CLM), results from hookworm larvae infestation, mainly A. braziliense or A. caninum. It is common in Sub-Saharan Africa, often acquired through soil contact, especially in sandy beaches, manifesting as serpiginous, erythematous, and intensely pruritic tracts within the epidermis and presenting with diverse clinical appearances. Diagnosis is mostly clinical, however, dermoscopy can enhance diagnostic accuracy and distinction from mimics. The current body of literature is deficient in its representation of dermoscopic data for CLM in blacks...

Cutaneous larva migrans (CLM) is a dermo-epidermal parasitic infection with a disproportionate incidence in developing countries, particularly in, and near tropical areas. It is characterized by erythematous, twisting, and linear plaques that can migrate to adjacent skin. Herein, we present an otherwise healthy 45-year-old woman who acquired a pruritic, erythematous, and serpiginous rash localized to her right medial ankle during a trip to New England. Oral ivermectin, the preferred first-line treatment for cutaneous larva migrans, was administered in combination with triamcinolone...
