1/16. Cordylobia anthropophaga mastitis mimicking breast cancer: case report.A case of furuncular myiasis of the breast due to infestation by the larva of Cordylobia anthropophaga in a young lady is presented. Some of the physical presentations of Cordylobia anthropophaga mastitis are similar to those of carcinoma of the breast. High index of suspicion in endemic areas, including patients who had visited such areas, the characteristic intense itching of the affected breast, the use of the magnifying hand lens and subsequent extraction of the offending maggots are the invaluable aids to diagnosis and treatment. The ulcer left on the breast after extraction of the maggot should be biopsied and the associated ill defined mass and skin changes must be seen to resolve completely before carcinoma of the breast can be safely ruled out. The various methods of extraction and the preventive measures are highlighted. Though furuncular myiasis has been reported to involve every part of domestic animals, this is the first reported case in literature involving the human breast.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
2/16. Vulvar myiasis due to Wohlfahrtia magnifica.myiasis is a condition resulting from the invasion of tissues or organs of man or animals by the larvae of dipterous flies. The distribution of myiasis is worldwide, with more cases being reported from tropical, subtropical, and warm temperate areas. The various forms of myiasis may be classified from an entomological or a clinical point of view. This report describes a rare case of vulvar myiasis due to Wohlfahrtia magnifica in an otherwise healthy 20-year-old Iranian female. To our knowledge, this is the first report of cutaneous myiasis of the vulva due to W. magnifica from iran and the middle east region.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
3/16. Neonatal myiasis.This case involves an orphan female neonate-abandoned in a dustbin in Poona, india-who was infected by the larval forms of the blowfly. The blowfly causing this infestation belonged to the family Calliphoridae and genus Calliphora. The fly of this genus is of importance in Indian veterinary science and is found abundantly around decaying matter in Poona. The larvae occurring in carrion, flesh, etc, usually infest open wounds of animals and rarely infest humans.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
4/16. Are cutaneous reactions to fly larvae mediated by CD4 , TIA NK1.1 T cells?BACKGROUND: Although there have been reports of fly larvae in wounds and as isolated primary infestations, there have been only rare reports documenting reactions to the larvae within the skin in humans and animals. There have been no reports documenting the histopathologic and immunohistochemical characteristics of the inflammatory infiltrate. OBJECTIVE: We present a patient who developed local pruritus, erythema, and swelling approximately three weeks after infestation by a fly larva within the scalp. Histopathologically the biopsy site showed a mixed infiltrate containing lymphoid cells and numerous eosinophils. Immunohistochemical stains showed predominantly CD4 T cells expressing an ab T-cell receptor (TCR) of which approximately 30% coexpressed T-cell intracellular antigen (TIA) and CD56. In addition, there were approximately 5% of these CD4 T cells which coexpressed CD30. CONCLUSIONS: Histopathologic and immunohistochemical findings are consistent with an effector cell population of cytotoxic CD4 T cells that produce a T-helper 2 cytokine pattern. The phenotype of this subset of T cells is unique and among its characteristics is that antigens--usually nonprotein antigens--are presented to these CD4 ,TIA natural killer (NK)1.1T cells by CD1d molecules.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
5/16. Case report: ophthalmomyiasis externa in Dallas County, texas.Ophthalmomyiasis externa is an uncommon condition in north america. If not recognized and managed accordingly, it can be complicated by the potentially fatal condition ophthalmomyiasis interna. Ophthalmomyiasis externa is mainly caused by the sheep bot fly Oestrus ovis; thus, it is more common in farming communities. We report a case of ophthalmomyiasis externa in a young woman from Dallas County, texas, who had no known history of contact with farm animals.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
6/16. Intestinal myiasis due to Musca domestica: a report of two cases.myiasis is the infestation of live human and vertebrate animals with dipterous larvae, which, at least for a certain period, feed on the host's dead or living tissue, liquid body substances, or ingested food. Intestinal myiasis is usually an accidental phenomenon, which occurs due to the ingestion of eggs or larvae present in food. Usually the patient is asymptomatic and the larvae are excreted harmlessly in the feces. In some cases, however, the passage of larvae may be associated with symptoms. The present paper describes two such cases.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
7/16. myiasis with Lund's fly (Cordylobia rodhaini) in travelers.myiasis is an infestation of human tissue by the larvae of certain flies. There are many forms of myiasis, including localized furuncular myiasis, creeping dermal myiasis and wound and body cavity myiasis.1 Cordylobia anthropophaga (the Tumbu fly) and Dermatobia hominis (the human botfly) are the most common causes of myiasis in africa and tropical America respectively. The genus Cordylobia also contains two less common species, C. ruandae and C. rodhaini. The usual hosts of C. rodhaini are various mammals (particularly rodents), and and humans are accidentally infested. Figure 1 shows the life cycle of C. rodhaini, which occurs over 55 to -67 days.3 The female fly deposits her eggs on dry sand polluted with the excrement of animals or on human clothing. In about 3 days, the larva is activated by the warm body of the host, hatches and invades the skin. As the larva matures, it induces a furuncular swelling. In 12 to -15 days, the larva reaches a length of about 23 mm, exits the skin and falls to the ground to pupate. The adult fly emerges in 23 to -26 days, and the life cycle resumes. In humans, the skin lesion starts as a red papule that gradually enlarges and develops into a furuncle. In the center of the lesion an opening forms, through which the larva breaths and discharges its serosanguinous feces. The lesion is associated with increasing pain until the larva exits the skin. The disease is usually uncomplicated and self-limiting.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
8/16. Furuncular myiasis caused by Dermatobia hominis, the human botfly.myiasis is a common travel-associated dermatosis. Travelers to many parts of Central and south america are susceptible to infestation by Dermatobia hominis. Despite the common name of human botfly, D hominis infests a broad range of mammals and is a severe pest to economically important farm animals in endemic regions. The adult female does not lay the eggs on the host. Instead, the adult female infests hosts indirectly by using blood-feeding arthropods to serve as phoretic vectors to transport the eggs. We present a patient who acquired Dermatobia when bitten by a day-active mosquito during a visit to guatemala. He had a locally painful, firm furuncular lesion with a central pore that drained serosanguineous exudates. The patient applied an occlusive ointment and recovered the larva after it emerged. In this report we discuss the life cycle of D hominis, the differential diagnosis, and therapeutic approaches.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
9/16. Unusual botfly skin infestation.myiasis, the infestation of humans and animals with fly larvae, is observed in tropical, lowland areas. Dermatobia hominis is a common cause of cutaneous human infestation in these areas. patients often present with a furuncular lesion on the extremities, back, or scalp. We report a case of furuncular myiasis in a patient returning from a trip to south america. We will discuss the life-cycle of D. hominis and the clinical findings important in the diagnosis of myiasis.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
10/16. A case of cutaneous myiasis caused by Wohlfahrtia magnifica.myiasis is caused by the invasion of tissues or organs of man or animals by dipterous larvae. The disease is infrequent in turkey; it is observed particularly in people with some predisposing factors. A 46-year-old male farmer with nevoid basal cell carcinoma syndrome (NBCCS) presented with the complaint of a blood-tinged discharge and pain in the left frontal-temporal region for three days. physical examination revealed live maggots in the ulcerous wound resulting from basal cell carcinoma. The larvae were removed with forceps, and the wound was locally dressed with povidone-iodine. The maggots were identified as the third instar larvae of Wohlfahrtia magnifica.- - - - - - - - - - ranking = 1keywords = animal (Clic here for more details about this article) |
