Oral and maxillofacial myiasis associated with epidermoid carcinoma: a case report

Abstract

Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions, alcoholism and senility. Its diagnosis is made basically by the presence of larvae. This paper reports a case of oral and maxillofacial myiasis involving 273 larvae in a patient with epidermoid carcinoma without physical or neurological deficiency. The patient's management was antisepsis, larval removal and general care, before death after three months.

Myiasis Associated with Oral Squamous Cell Carcinoma - A Literature Review

“…Extensive myiasis infestations associated with oral SCC have been reported in the literature, though they are very few (Gopalakrishnan et al, 2008;Carvalho et al 2008;Pessoa L, Galvão 2011;Gabriel et al, 2008;Biradar et al, 2015). It is possible that this condition is underreported, as oral cancer is a common malignancy.…”

“…It has been seen more often in association with cutaneous cancer (Wollina et al, 2014). Although a rare, many oral myiasis cases associated with squamous cell carcinoma have been reported in the literature (Carvalho et al, 2008;Gabriel et al, 2008;Pessoa and Galvão, 2011;Biradar et al, 2015). Some reports have documented the occurrence of myiasis in association with skin cancer including the head and neck region (Sesterhenn et al, 2009;Wollina et al, 2014).…”

Insurgence of Maggots Around Colostomy: An Unusual Presentation

“…Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae [11][12][13][14][15]. Myiasis was defined by Zumpt as the infestation of live human and vertebrate animals by dipterous larva, which at least for a certain period feed on host's dead or living tissue, liquid body substances or ingested food [16].…”

Oral myiasis: A case report in a child with cerebral palsy

“…Oral myiasis is a rare condition observed in growing children and in healthy adults; however, this infection has frequently been reported in patients with mental deficiencies (5,(7)(8)(9). In addition, alcoholism, senility, hemiplegia and an open mouth during sleep may facilitate the development of oral myiasis (5).…”

“…Recently, ivermectin, a semi-synthetic macrolide antibiotic used in veterinary medicine, has been applied to the treatment of oral myiasis. This medication activates the release of gamma-aminobutyric acid which induces the death of the larvae and their spontaneous elimination (7,9). In view of the systemic conditions of the present patient, complete removal of the larvae and abundant irrigation with saline solution were adopted as treatment (6) without administration of additional medication since the patient was treated for severe anemia and pneumonia and already received medication.…”
