We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

Advanced oral squamous cell carcinoma (SCC) is a possible risk factor for myiasis, a parasitic infestation of vital tissue of humans or other mammals by dipterous larvae (maggots). Oral myiasis is a rare entity, and is mostly associated with various medical and anatomical conditions, such as neglected mandibular fracture, lip incompetence, cerebral palsy, poor oral hygiene, suppurative lesions, and cancerous wounds. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threating hemorrhage. The aim of the present article was to highlight the occurrence of oral myiasis in association with squamous cell carcinoma and also to highlight the treatment and preventive approaches for such cases. A literature search was performed using MEDLINE for articles published in English relating to the occurrence of oral myiasis in oral SCC. Our search revealed 6 reports on myiasis associated with oral SCC. The surgical debridement of infected tissue with the removal of maggots is the treatment of choice in most cases of oral myiasis.

A 71-year old male patient was admitted in Inha hospital due to right facial palsy, quadriplegia and aphasia. This patient was operated to replace his heart valves 7 years ago and has been treated with Coumarin. an anti-coagulant drug. to prevent the formation of thrombus in the hpart. A number of fly maggots continuoully crawled out from the nasogastric tube set up for supplying a liquid diet and patient's mouth for 2 days until his death in the intensive care unit of hospital. These maggots were about 11.5 mm long on the average and identified as genus Lucilio belonging to family Calliphoridae. The lesion of this myiasis case might be regarded in the castro-intestinal . System of patient. This is the first report of an internal myiasis case in Korea.

Four cases of gastric or intestinal myiasis are reported. The cases contain 2 males (1 child 10 years old, and 1 adult 40 years old) and 2 females (1 girl 18 years old, and 1 adult 50 years old) from Minia Governorate, Southern Egypt. Three of them, including cases no. 1, 3, and 4, were gastric myiasis, and complained of offensive hematemesis of bright red blood. Minute moving worms, larvae of the fly, were found in the vomitus. On the other hand, case no. 2 had intestinal myiasis, and complained of abdominal distention, nausea, vomiting, and diarrhea. The stool of case 2 was mixed with blood, and minute moving worms were observed in the stool. Endoscopy was performed to explore any pathological changes in the stomach of the patients. The larvae were collected and studied macroscopically, microscopically, and using a scanning electron microscope (SEM) to identify their species. Three different types of larvae were identified. The larvae isolated from case 1 were diagnosed as the second stage larvae of Sarcophaga species, and the larvae isolated from case 2 were the third stage larvae of Sarcophaga species. On the other hand, the larvae isolated from cases 3 and 4 were diagnosed as the third stage larvae of Oestrus species.

Internal myiasis is a rare disease, which has not been reported in Korea, yet. This case report describes a patient with pneumonia associated with internal myiasis. She was 84-year old female who was admitted to the emergency department, Konyang University Hospital as a result of dyspnea and fever and a drowsy mental state. Approximately twenty fly maggots continuously crawled out from the nose at the third hospital day in the intensive care unit. These maggots were almost 7.2mm long and were identified as the genus lucilia belonging to the family Calliphoridae. In addition, a bronchial washing study showed eggs of the dipterous larvae. A lesion of this myiasis case might have been located in the respiratory system of patient. This case is the first internal myiasis of the respiratory system reported in Korea. This cases is discussed with a review of the relevant literature.

Myiasis is the parasitic infestation of the body of a live animal by fly larvae that grow inside the host while feeding on its tissue. Necrotic tissue is a favorable environment for larvae to thrive, which can be seen easily in patients with a diabetic foot. Myiasis in a diabetic foot is rare but is constantly being reported. The common larvae genera causing myiasis are Calliphoridae, Sarcophagidae, and Muscidae. This paper reports a rare case of sarcophaga myiasis in a diabetic foot. To the best of the author's knowledge, this is the first case report in Korea regarding human myiasis with the sarcophaga genus.

The cutaneous myiasis has been rarely reported in the Republic of Korea. We intended to describe here a case of furuncular cutaneous myiasis caused by Cordylobia anthropophaga larvae in a Korean traveler returned from Central Africa. A patient, 55-year-old man, had traveled to Equatorial Guinea, in Central Africa for a month and just returned to Korea. Physical examinations showed 2 tender erythematous nodules with small central ulceration on the left buttock and thigh. During skin biopsy, 2 larvae came out from the lesion. C. anthropophaga was identified by paired mouth hooks (toothed, spade-like, oral hooklets) and 2 posterior spiracles, which lack a distinct chitinous rim. Although rarely described in Korea until now, cutaneous myiasis may be encountered more frequently with increasing international travel and exchange workers to tropical areas.

A fly larva was recovered from a boil-like lesion on the left leg of a 33-year-old male on 21 November 2016. He has worked in an endemic area of myiasis, Uganda, for 8 months and returned to Korea on 11 November 2016. The larva was identified as Cordylobia anthropophaga by morphological features, including the body shape, size, anterior end, posterior spiracles, and pattern of spines on the body. Subsequent 28S rRNA gene sequencing showed 99.9% similarity (916/917 bp) with the partial 28S rRNA gene of C. anthropophaga. This is the first imported case of furuncular myiasis caused by C. anthropophaga in a Korean overseas traveler.

Megaselia scalaris (Diptera: Phoridae) is one of the medically important insects. Maggots from a urine sample of a 5-year-old Saudi girl were examined microscopically for identification. These maggots were cultured to become adult flies. Larvae and adults were identified using standard keys. Protozoan flagellates were obtained from the gut of the larvae. This is the first report of M. scalaris as a causative agent of urinary human myiasis in Saudi Arabia.

We report a case of myiasis on the left submandibular area after radiation therapy for squamous cell carcinoma. A 77-year-old man visited our hospital, 7 weeks after complicating a course of radiation therapy, had a 7cm diameter necrotic ulcer on the left submandible. The margin of the lesion were undermined by numerous interlinking passages containing 20 maggots. The maggots were removed by simple extraction and were identified as Calliphoridae Lucilia. The probable origin of the myiasis in this case was attributed to poor environmental condition and general weakness of the patient. Oppotunistic cutaneous myiasis can be prevented by protecting open wounds from flies, wound should not be left without a covering capable of excluding flies, especially in the summer month.
