Late presentation of breast cancer is more likely to be complicated and fatal. Local invasion, tissue destruction, skin lose, and superadded infection/infestation make surgical intervention very challenging.

Review
Myiasis is a disease caused by fly larvae that grow in the tissues of animals and humans. It can cause a variety of local symptoms, like erythema or pain, depending on its location, and generalized symptomatology, such as fever and malaise. Myiasis can generate severe complications, for instance sepsis, or directly impact vital tissues. Its management varies depending on the location, and on the preferences of the doctor that faces this challenge. Myiasis usually occurs in tropical countries, and, in many places, it is not a rare condition. The cases are rarely reported, and there are no published management protocols. To review the literature regarding the most common agents, the predisposing factors and the treatment alternatives for otic myiasis, a rare form of human myiasis caused by the infestation of fly larvae in the ear cavities. We present a systematic review of the literature. The search in five databases (Medline, Embase, Cochrane Database of Systematic Reviews, LILACS and RedALyC) led to 63 published cases from 24 countries, in the 5 continents. The ages of the patients ranged from newborn to 65 years old. The most common agents belong to the or families. Chronic otitis media, previous otic surgical procedures, mental deficit, alcohol or drug abuse, sleeping outdoors, prostration, and malnutrition were predisposing factors. The treatment alternatives are herein discussed. The results highlight the need for monitoring, follow-up and standardization of medical approaches.

A traveler presented with a furuncular skin abscess and periorbital edema. A larva was surgically removed from the abscess and identified as a larva of . Myiasis caused by is called Lund's fly myiasis and only rarely is reported in humans. After disinfection, the remaining lesion healed without further intervention and the edema resolved.

Myiasis is a pathologic condition in humans occurring because of parasitic infestation. Parasites causing myiasis belong to the order Diptera. Oral myiasis is seen secondary to oral wounds, suppurative lesions, and extraction wounds, especially in individuals with neurological deficit. In such cases, neglected oral hygiene and halitosis attracts the flies to lay eggs in oral wounds resulting in oral myiasis. We present a case of oral myiasis in 40-year-old male patient with mental disability and history of epilepsy.

Review
Myiasis is an infestation caused by larvae of Diptera in humans and other vertebrates. In domestic cats, Felis silvestris catus L. (Carnivora: Felidae), four dipteran families have been reported as agents of obligatory and facultative myiasis: Oestridae, Calliphoridae, Sarcophagidae and Muscidae. Among agents of obligatory myiasis, the most frequent genus is Cuterebra Clark (Oestridae) and the most frequent species is Cochliomyia hominivorax (Coquerel) (Calliphoridae). Among the agents of facultative myiasis, the most frequent species is Lucilia sericata (Meigen) (Calliphoridae). A survey of myiasis in cats reported in literature shows that the cases are distributed worldwide and linked to the geographical range of the dipteran species. Factors favouring the occurrence of myiasis in cats are prowling in infested areas, poor hygiene conditions due to diseases and/or neglect, and wounds inflicted during territorial or reproductive competition. The aim of the review is to provide an extended survey of literature on myiasis in cats, as general information and possible development of guidelines for veterinarians, entomologists and other researchers interested in the field.

Observational Study
BACKGROUND
Cutaneous myiasis is a well-established diagnosis in returning travelers from tropical countries. The most common form of myiasis seen in this population is localized furuncular myiasis caused by Dermatobia hominis and Cordylobia anthropophaga. There are limited data on the disease course and outcome in travelers to tropical countries.
METHODS
A retrospective observational study of patients who presented with myiasis was conducted between 1999 and July 2014 in the post-travel clinics in Israel. Data regarding exposure history, travel duration, clinical presentation, treatment, and parasitological identification were collected and analyzed.
RESULTS
Among 6,867 ill returning Israeli travelers, 1,419 (21%) had a dermatologic complaint, 90 (6.3%) of them were diagnosed with myiasis. Myiasis was acquired in Latin America by 72 (80%) patients, mainly (54%) in the Madidi National Park, Amazonas Basin, Bolivia; 18 cases (20%) were acquired in Africa. In 76% of cases, manual extraction was sufficient to remove the larva; 24% required surgical intervention. Despite the fact that most patients did not receive antibiotic treatment, only one developed secondary infection, upon partial removal of the larva.
CONCLUSIONS
This is the largest myiasis case series in ill returning travelers. Myiasis is not a rare dermatologic complaint with most Israeli cases imported from Latin America and specifically the Madidi National Park in Bolivia. Treatment is based on full extraction of the larva after which no antibiotic treatment is needed. Myiasis is a preventable disease and travelers should be informed of the different preventive measures according to their travel destination.
