Penile myiasis as a differential diagnosis for genital ulcer: a case report

SUMMARY Myiasis is defined as the infestation of live vertebrates (humans and/or animals) with dipterous larvae. In mammals (including humans), dipterous larvae can feed on the host's living or dead tissue, liquid body substance, or ingested food and cause a broad range of infestations depending on the body location and the relationship of the larvae with the host. In this review, we deeply discuss myiasis as a worldwide infestation with different agents and with its broad scenario of clinical manifestations as well as diagnosis techniques and treatment.

“…Cases of vulvar myiasis had been reported from Brazil due to W. magnifica (Delir et al 1999) and by C. hominivorax (Passos et al 2002). A case of penile myiasis by D. hominis was reported in a 62-year-old male patient, who was a retired military official from Rio de Janeiro state, Brazil (Passos et al 2008), and a 41-year-old male patient from Brazil with advanced epidermoid carcinoma of the penis, in which urgent partial penectomy was performed (Tavares et al 2007). Two case of urinogenital myiasis caused by L. sericata and W. magnifica (Salimi et al 2010b) and a case of vaginal myiasis due to Fannia scalaris (Hezarjaribi et al 2014) had been reported from Iran.…”

Myiasis, the infestation of tissues of live humans and other vertebrate animals with dipteran larvae (maggots), is a phenomenon of widespread occurrence throughout the tropical regions of the world. It is commonly seen in domestic and wild animals but occurs rarely in man also. The tissue invasion in man by maggots is generally a well-recognized complication of neglected wounds. The condition may be asymptomatic but occasionally results in more or less severe problems and even death when larvae invade body cavities or areas that forbid their direct visual examination. Many cases of myiasis, however, usually do not reach the attention of medical practitioners because of the tendency of the mature larvae to migrate out of the lesion for pupation. In the present study, the authors reviewed the past literature describing the cases of human myiasis, causative fly species and predisposing factors for the onset of the same. The aim of the present manuscript is to provide a database for the future reference of medical entomologists, medical practitioners and veterinarians. Review of literature revealed that 37 fly species belonging to ten families were responsible worldwide for the onset of human myiasis. The incidence of myiasis among humans can be correlated to increasing fly populations, poor hygienic conditions and presence of domestic animals in the close vicinity. Other factors responsible for myiasis include neglected open wounds and foul-smelling discharge from natural body openings. Moreover, ignorance plays a key role in its occurrence since people are generally unaware about the actual cause and often correlate the condition to their superstitious beliefs. It is emphasized that the patients should not neglect their wounds and should take proper medical care; otherwise, myiasis may supervene.

“…Almost all cases are present on scalp, limbs and back although infestations of the eye, the breast and the genitalia have been observed. 3,7,[9][10][11][12][13][14][15][16][17][18][19] A case of an erysipelas-like lesion resulting from an unusual infestation with nine larvae of Dermatobia hominis was described. In this case local application of petroleum jelly allowed the exit all larvae.…”

Background: Myiasis is defined as invasion of tissues by Diptera flies. The condition is endemic in the forested areas of Mexico, Central and South America.Main Observations: A 61-year old woman presented with two boil-like inflammatory and painful lesions on her back. She had been travelling in Central America. Biopsies revealed a myiasis with mature third instar larvae of Dermatobia hominis, a diptera fly endemic in this region. Complete surgical excision and systemic antibiosis led to a delayed but complete healing. Conclusion:We presented a patient with a double infestation by Dermatobia hominis. Dermatologists should be aware of this disease, which has become increasingly common in travellers and is seen now also in unusual regions, other than Central and South America.
