Facial wrigglies: live extralymphatic filarial infestation in subcutaneous tissues of the head and neck

A rare case of ocular filariasis caused by Brugia malayi

Extra-lymphatic manifestation of filariasis is uncommon and may usually be clinically misdiagnosed. The extra lymphatic presentation of Brugia malayi may due to the site of entry of the infective larvae, and only a few cases have been proven for the causative species. We report here a 59-year-old woman presented with swollen right conjunctiva and complaint of migratory swelling at her eyelid, which has turned out to be ocular filariasis by B. malayi in Chantaburi province, Thailand. This report highlights the increasing cases of B. malayi as a causative agent of ocular filariasis in human.

Cervical Lymphatic Filariasis in a Pediatric Patient: Case Report and Database Analysis of Lymphatic Filariasis in the United States

Lymphatic filariasis is a mosquito-borne parasitic infection caused by Wuchereria bancrofti and Brugia spp. Commonly seen in tropical developing countries, lymphatic filariasis occurs when adult worms deposit in and obstruct lymphatics. Although not endemic to the United States, a few cases of lymphatic filariasis caused by zoonotic Brugia spp. have been reported. Here we present a case of an 11-year-old female with no travel history who was seen in our clinic for a 1-year history of painless left cervical lymphadenopathy secondary to lymphatic filariasis. We review the literature of this infection and discuss the management of our patient. Using the National Inpatient Sample (NIS), the largest publicly available all-payer inpatient care database in the United States, we also examine the demographics of this infection. Our results show that chronic lymphadenopathy in the head and neck is the most common presenting symptoms of domestic lymphatic filariasis. Diagnosis is often made after surgical lymph node excision. Examination of the NIS from 2000 to 2014 revealed 865 patients admitted with a diagnosis of lymphatic filariasis. Most patients are in the mid to late sixties and are located on the eastern seaboard. Eight hundred and twenty six cases (95.5%) were likely due to zoonotic Brugia spp. and 39 (4.5%) due to W. bancrofti. Despite being rare, these data highlight the need to consider filariasis in patients presenting with chronic lymphadenopathy in the United States.

Cutaneous Manifestations of Selected Parasitic Infections in Western Pacific and Southeast Asian Regions

Cutaneous manifestations of parasitic infections often result in discomfort, debilitation, and even stigmatization. Data on cutaneous manifestations of parasitic infections, however, are limited. This article provides updates on the cutaneous manifestations of parasitic infections which are known to occur in Western Pacific and Southeast Asian regions, such as scabies, pediculosis, cutaneous larva migrans, larva currens, cutaneous schistosomiasis, cutaneous enterobiasis, cutaneous cysticercosis, acute dermatolymphangioadenitis (lymphatic filariasis), and cutaneous amoebiasis. The lack of epidemiological data on these conditions suggests the need for improvements in recording and reporting of cases. Utilization of advance diagnostic modalities and capacity building of health workers are important for proper case management. Cutaneous manifestations of parasitic infections are a topic rarely studied and thus represent an opportunity for further research.

Ultrasound Visualization of Atypical Abscess Ultimately Containing Bot Fly Larva

BACKGROUND

Because of the rise in community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), presentations to the emergency department for the evaluation of cutaneous abscesses have risen dramatically over the past 2 decades. Soft tissue point of care ultrasound (POCUS) differentiates abscess from cellulitis, determines the size and shape, and characterizes the contents of the abscess. It has been shown to improve medical decision-making and therefore the emergency management of cutaneous abscesses over physical examination alone.

CASE REPORT

We report a case of an unusual nonhealing abscess in an 18-year-old woman with a recent history of foreign travel where soft tissue POCUS identified motion within the abscess pocket. This changed the management of the case, leading to the diagnosis of bot fly myiasis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should entertain a broader differential for an apparent abscess and consider liberal use of soft tissue POCUS in these cases.

Extra-lymphatic filariasis at reconstructive surgery flap site recurrence of head and neck cancer

Filarial infection is commonly encountered in the Indian subcontinent. Here we present a clinical image of filarial infestation at the site of recurrence of head and neck cancer.
