Unusual presentation of the urogenital myiasis caused by Luciliasericata (Diptera: Calliphoridae)
Introduction and objective:
The case report describes the unusual presentation of the urogenital myiasis caused by Luciliasericata in two Slovakian men.
Material and methods:
The first patient, aged 66, who suffered from a locally advanced and inoperable urinary bladder dedifferentiated TCC with bilateral ureteral obstruction, chronic renal insufficiency and non-functioning left kidney. After surgical exploration the patient developed a malignant vesico-intestino-cutaneous fistula with stool leakage through the open wound. Because of very poor hygiene, and unsatisfactory attendance by staff, a fly deposited ova in the patient's necrotic wound. The patient died three months later of metastatic cancer disease. The second patient, a 43-year old homeless alcoholic male had gangrene of the scrotum and penis, urethro-cutaneous urinary fistula with numerous live and motile larvae on the surfaces. In both patients, some larvae were removed and sent to the lab for identification. The larvae were identified as maggots of the fly Luciliasericata. Antibiotic therapy, disinfection and debridement with sterile covering of the wound were used.
For both patients, complex treatment of myiasis was successful and patient recovered without parasitic consequences.
To our knowledge, this is the first report of the unusual presentation of the urogenital myiasis in Slovakian men with poor social habits and hygiene.

- "It is used to describe infestations, both obligatory and accidental, in vertebrate animals and humans by certain dipterous larvae (maggots), which feed upon the living, necrotic or dead tissues for at least a period of time (Robbins and Khachemoune 2010, Sotiraki and Hall 2012). Human myiasis is a rare clinical condition but more frequently seen in underdeveloped countries and tropical and subtropical areas, which are associated with poor hygiene, bad housing conditions, suppurative lesions, alcoholism and senility (Verettas et al. 2008, Bayindir et al. 2012, Nagy 2012). Moreover, unsatisfactory wound care contributes to the development of myiasis on humans. "

ABSTRACT: On examination of the wound of a patient who was treated previously with external fixation for a diaphysial fracture of the femur, we observed the presence of multiple living larvae (maggots) of dipterous flies. Treatment included removal of the maggots and use of antibiotic. The importance of hygiene and sanitation is discussed.

ABSTRACT: Auricular tumors constitute 6% of all head-neck tumors. Malignant tumors of the auricula are generally squamous or basal cell carcinomas. Myiasis rarely occurs in healthy individuals. In general, it is a parasite that is seen in patients with mental retardation or psychiatric disorders, elderly individuals, those with poor self-care and hygiene, and those with immune system disorders. In humans, it is mainly seen in tropical and subtropical regions; however, in rare instances, it may be seen in other regions of the world. In the literature, there are limited numbers of myiasis cases reported from Turkey. In this study, we aimed to present a myiasis case (Wohlfahrtia magnifica) involving cutaneous and subcutaneous tissues with an underlying head-neck cancer, which, to the best of our knowledge, has not been reported before in the literature.
