Case Report: Ophthalmomyiasis Externa Caused by Cordylobia anthropophaga Masquerading as a Lid Abscess.

Myiasis is a neglected tropical disease caused by the larvae of dipterous flies. Cutaneous infestation is the predominant type documented in sub-Saharan Africa, and ocular involvement is uncommon. We report the rare occurrence of a case of eyelid ophthalmomyiasis caused by Cordylobia anthropophaga in a Nigerian female to raise awareness among practitioners in both tropical and nonendemic areas.

Unusual case of lagochilascariasis with breast involvement: the first case report in pregnancy.

Lagochilascariasis is a neglected neotropical helminthiasis, responsible for human infections through the ingestion of raw or undercooked meat from wild animals infected by larvae encysted in their tissues. It is characterized by a chronic evolution with periods of remission and recurrences, affecting mainly the head and neck regions. It can progress to death by invasion of the central nervous system. It is caused by the Lagochilascaris minor nematode, first described in 1909 and mainly found in the Brazilian Amazon ecosystem, notably in Para State. In May 2010, a 15-year-old female, born in the city of Aveiro, Para State, was hospitalized in the city of Santarem, Para State, presenting with cervical and spinal abscesses and osteolytic lesions at T3-T5 level. During hospitalization, white larvae identified as L. minor were observed in a cervical subcutaneous fistula. After the surgical drainage of abscesses, albendazole 400 mg/day was started, with improvement of symptoms. The patient abandoned the follow-up and in January 2016, during the 20th week of pregnancy, she was readmitted to the Santarem Municipal Hospital with new cervical abscesses in the infra-mammary region, with numerous larvae exiting by subcutaneous left breast fistulas. The antiparasitic treatment was restarted due to possible reactivation of the infection in the spine and dissemination to the central nervous system. Ten weeks after hospital discharge, the patient had resolution of the fistulas and decreased abscesses, without gestational complications. This is the first case report of lagochilascariasis during pregnancy, as well as of involvement of mammary glands.

Sporotrichoid Abscesses: A Rare Form of Recurrent Cutaneous Leishmaniasis in an Infant's Face.

An 8-month-old infant presented with a 3-month history of two swellings on her left cheek. Past history revealed cutaneous leishmaniasis (CL) of the same site 8 months earlier; the patient was treated with intralesional infiltrations of meglumine antimoniate over 4 months, leaving behind an atrophic scar. The current lesions started 1 month after the healing of the initial ones and gradually increased in size and later became fluctuant. She had been treated with several antimicrobial agents, without any improvement. Her examination revealed two subcutaneous inflammatory and renitent nodules of 2-3 cm in diameter on the left cheek, associated with a cribriform scar under the external angle of the left eye, corresponding with the CL. The abscesses were aspirated, revealing yellowish pus. Culture was negative for bacterial growth. Smears for Leishmania bodies performed, using Leishman and Giemsa stains and taken from both the subcutaneous abscesses and the dystrophic scar; were positive. The diagnosis of a lymphatic dissemination was established based on the previous history of CL treated with local therapy. The patient was started on intramuscular injections of meglumine antimoniate (60 mg/kg/day) for 21 days, and she responded well to the treatment, with complete disappearance of the lesions. Repeat skin smears were negative for Leishmania bodies.

Swine multifocal ulcerative colitis and crypt abscesses associated with Entamoeba polecki subtype 3 and Salmonella Typhimurium.

Piglets aged approximately 50 days exhibited diarrhea and wasting. Multiple white foci were detected in the colon of a dead piglet; histopathological findings revealed multifocal ulcers and crypt abscesses with Entamoeba trophozoites and gram-negative bacilli in the piglet. These pathogens were identified as Entamoeba polecki subtype 3 and Salmonella enterica serovar Typhimurium, respectively. Numerous E. polecki subtype 3 trophozoites were located on the edge of the ulcerative and necrotic lesions in the lamina propria. Crypt abscesses were associated with S. Typhimurium. These results suggest that E. polecki subtype 3 caused multifocal ulcerative colitis accompanied by crypt abscesses with S. Typhimurium in the piglet. This study is the first report of colitis with E. polecki subtype 3 and S. Typhimurium coinfection.

Guinea-worm (Dracunculus medinensis) infection presenting as a diabetic foot abscess: A case report from Kerala.

Dracunculiasis or guinea-worm infection is a water-borne, parasitic disease that can cause major morbidity. Dracunculiasis in patients with diabetes can be misdiagnosed as a diabetic foot abscess, which is a common complication of poorly controlled diabetes. This is a report of guinea-worm disease (GWD) in a 57-year-old man with diabetes from a rural area of Kerala. There is need for awareness among physicians about the occurrence of GWD in people with diabetes and the need to ensure supply of safe drinking water to prevent its re- emergence. Though WHO has declared India free of GWD, a few cases have been reported from the country.

Splenic abscess is extremely rare after amoebic dysentery. A case report and review of the literature.

Splenic abscess is a rare condition, which is often asymptomatic in the absence of comorbidity and is associated with high mortality rates. Given the importance of the differential diagnosis of patients who present to the emergency department with fever or septic shock, we report the case of a patient with amoebic splenic abscess who presented to our clinic with widespread skin rash and signs of septic shock following amoebic dysentery caused by Entamoeba histolytica, which is rarely reported in the literature. KEY WORDS: Amoebic Spleen Abscess, Amoebic Abscess, Entamoeba Histolytica, Splenic Abscess.

An exotic abscess within the United Kingdom from The Gambia: a case report.

BACKGROUND: Furuncular myiasis is a parasitic infection of a live mammal by fly larvae commonly seen in Africa. However, with an increase in international tourism, there is a significant rise in exotic infection in non-endemic areas which can pose a diagnostic challenge to doctors and potentially lead to delay in treatment. From the current literature, only 12 cases were reported in the UK. CASE PRESENTATION: We report an unusual case of multiple abscesses in a 32-year-old white British woman presenting to our Emergency department in the UK after returning from a holiday in The Gambia, West Africa. She did not complain of systemic symptoms and was otherwise fit and healthy with no significant past medical history. During examination, two maggots were expressed from the abscesses by applying lateral pressure to each lesion. The larvae were found to be Cordylobia anthropophaga. She was discharged with antibiotics to prevent secondary infection with no further follow-up. CONCLUSION: With globalization, the need for increasing awareness of tropical diseases has become important to win the battle against future epidemics.

Splenic Abscess in Immunocompetent Patients Managed Primarily without Splenectomy: A Series of 7 Cases.

INTRODUCTION: Splenic abscesses are rare in immunocompetent adults. Despite advances in diagnosis and treatment, these abscesses are still potentially life threatening. Various factors have been reported to predispose otherwise immunocompetent adults to splenic abscesses. Splenectomy was once considered the "gold standard" treatment. However, the trend is shifting to a conservative approach. CASE DESCRIPTION: We describe seven cases of splenic abscess in immunocompetent adults, the cause of which ranged from tuberculosis to salmonella and was as rare as Plasmodium vivax. All the patients presented with fever (median duration = one month; range = one week to six years) and abdominal pain, and most also had weight loss. All patients were in their third to fifth decades of life. The patients were successfully treated with appropriate antibiotic therapy, after which they were clinically normal. DISCUSSION: A microbiological diagnosis of splenic abscess is of utmost importance. In this series, all patients underwent percutaneous aspiration. This was performed under radiologic guidance (either ultrasonography or computed tomography). Only one patient required diagnostic splenectomy. Irrespective of whatever surgical or nonsurgical drainage measures are employed, appropriate antibiotic therapy is the cornerstone of management. The dose and duration of antibiotic therapy depend on the causative organism and its sensitivity pattern.

Enterobius vermicularis in tubo-ovarian abscess: A rare and interesting incidental finding - A case Report.

Enterobius vermicularis is a common intestinal nematode; however, rare extraintestinal Enterobius infections have been reported from different parts of the world. Here, we present a case of tubo-ovarian abscess in an otherwise healthy young sexually active female with no known comorbids with history of on and off lower abdominal pain for one year and high grade fever for one month. On the basis of further workup and radiological evaluation, a preoperative diagnosis of right sided tubo-ovarian abscess was made and salpingo-oophorectomy was performed laproscopically in July 2015. Histopathology of the resected tissue revealed necrosis and in one area Enterobius vermicularis was identified surrounded by neutrophils and eosinophil rich abscess. A final diagnosis of severe acute and chronic salpingo-oophoritis with abscess formation, secondary to Enterobius vermicularis was made. Signs and symptoms of parasitic involvement in tubo-ovarian abscesses are not much different than usual presentations of pelvic inflammatory diseases and identification of a parasite in a tubo-ovarian tissue sample is a rare clinical finding. A high index of suspicion on the part of histopathologist as well as clinician is important for timely diagnosis and effective management of such cases.

HEPATIC LYMPHOMA AND SPLENIC ASPERGILLOSIS MIMICKING HEPATOSPLENIC ABSCESSES FROM MELIOIDOSIS IN THAILAND.

We report here a case of hepatic lymphoma and splenic aspergillosis in an elderly patient with diabetes mellitus, exhibiting hepatosplenic abscesses mimicking melioidosis. Immunohistochemistry confirmed the diagnosis of a diffuse hepatic large B-cell lymphoma. Biopsy of the spleen revealed a clump of fungus with a slender shape and dichotomous branching, morphologically consistent with aspergillosis. Hepatosplenic abscesses are a common presentation in melioidosis, but this case reveals this assumption can lead to misdiagnosis. Histological and microbiological confirmation are required, especially in patients with hepatosplenic lesions.

A Case of Lagochilascariasis in Suriname with the Involvement of the ENT System and the Skull Base.

We describe a case of human lagochilascariasis, with skull-base involvement and a chronic and relapsing course after treatment. This rare parasitic infection is usually manifested in the head and neck area, characterized by progressive granulomatous inflammation and the formation of abscesses. Transmission to humans most likely occurs by the consumption of undercooked meat of wild rodents. On the basis of literature studies, we propose the most likely life cycle of the parasite that involves wild feline and rodent species, with humans as accidental hosts. Even in endemic areas, it is very difficult to recognize the disease at an early stage. Progression will eventually lead to involvement of the (central) nervous system, as described in our case. Treatment is often difficult and involves resection and prolonged treatment with anthelmintic drugs. Recurrences are not uncommon and at present, long-term oral administration of ivermectin seems to be the most effective treatment.

[Furuncular myiasis: Case report of a cutaneous parasitosis usually considered as an abscess]. / La myiase furonculeuse: Cas clinique d'une parasitose cutanée souvent confondue avec un abcès.

Furuncular myiasis is a wel l established cutaneous parasitosis in tropical area. In Europe, most of cases have been described in patients returning from risk areas. We report a case of a 4-year old child with a furuncular lesion on his left thigh considered as an abscess and who was send to emergency department for surgical drainage.

La myiase furonculeuse est une parasitose cutanée bien connue dans les régions tropicales. En Europe, des cas rares ont été décrits chez des patients ayant séjourné dans les zones à risque. Nous rapportons le cas d'un enfant de 4 ans présentant un furoncle au niveau de la cuisse gauche considéré à tort comme un abcès et envoyé aux urgences pour drainage.

A 29-year-old man with an unusual cause of an abscess.

A 29-year-old man with no medical history presented with a left scalp abscess and left temporal oedema. He was initially started on treatment for community acquired Methicillin-resistant Staphylococcus aureus with sulfamethoxazole and trimethoprim. Over the next 2 weeks, his swelling improved; however, he continued to have localised swelling and drainage from the area. Eventually, larvae of a botfly were removed from his scalp, and his symptoms resolved.

Amoebic anal fistula: new insight into an old disease.

A 67-year-old gentleman underwent fistulectomy for low trans-sphincteric anal fistula along with curettage for an associated abscess extending proximally for half a centimeter into the intersphincteric plane. The roof of the cavity became clearly visible after satisfactory culmination of the surgical procedure. Histopathological examination of the fistulous tract and the curetted granulation tissue revealed presence of multiple trophozoites of Entamoeba histolytica exhibiting erythrophagocytosis in the background of mixed inflammatory infiltrate. This case report provides the outlook that yields the novel insight into the possible role of Entamoeba histolytica in the pathogenesis and persistence of the fistulous tract.

Enterobius vermicularis: Can it be a possible pathogen in Bartholin gland abscess formation?

The most frequent disorders of the Bartholin glands are cysts or abscesses. Bartholin gland abscesses occur generally as a result of polymicrobial infections or agents that cause sexually transmitted diseases. But as far as we know, no parasite has been previously reported among the infectious agents that are detected from the abscesses of the Bartholin gland. Here, we report a 45-year-old woman, in the Bartholin abscess aspirate of whom Enterobius vermicularis eggs were detected in between the inflammatory infiltrate by cytological examination.

The first genetically confirmed case of Dioctophyme renale (Nematoda: Dioctophymatida) in a patient with a subcutaneous nodule.

We describe a nematode larva in a subcutaneous nodule excised from a 44-year-old Chinese male who had been living in Japan for 15 years. Morphological features suggested that the worm was a dioctophimatid nematode. PCR amplification and sequencing of small subunit ribosomal DNA and mitochondrial cytochrome subunit c oxidase genes allowed us to identify the larva as the giant kidney worm, Dioctophyme renale (Goeze, 1972). This is the first molecularly confirmed human case of a dermal D. renale infection.

Dirofilaria repens infection in a ten-year-old boy from the Istria Peninsula: case report.

Dirofilariasis is a zoonotic infection caused by worms belonging to the genus Dirofilaria. The disease is transmitted by mosquitoes and the hosts are usually dogs. Infections in humans are rare and they usually manifest as a subcutaneous nodule or a conjunctival form. We present a 10-year-old boy with a subcutaneous nodule on his left forearm, who was admitted to the hospital. On examination, the only significant findings were high levels of eosinophils. The pediatrician suspected dirofilariasis and the boy was referred to pediatric surgery. The whole lesion was surgically removed and histopathologic examination confirmed parasitic infection by Dirofilaria repens. Although human dirofilariasis is a rare disease, the number of reported cases has recently increased worldwide. The disease mainly occurs in southern European countries, but has also been described in eastern Europe, Central Asia and Sri Lanka. Croatia is one of the endemic areas for dirofilariasis, especially in the region of the Istria Peninsula. The case presented highlights the requirement for further monitoring of endemic areas in order to establish effective preventive measures.

Dermoscopy: Ex vivo visualization of fleas head and bag of eggs confirms the diagnosis of Tungiasis.

Tungiasis, caused by the impregnated female sand flea Tunga penetrans, is increasingly common in returned travellers from endemic areas. Clinical suspicion is raised by the clinicodermoscopic correlation, leading to rapid treatment which involves extraction of the intact flea. Ex vivo dermoscopy demonstrates the parasite's head and distended abdomen full of eggs, confirming the diagnosis.
