[An unusual Wohlfahrtia magnifica myiasis case localized in cutaneous and subcutaneous tissues in a patient with head-neck cancer]. / Bas Boyun Kanserli Hastada Kutaneöz ve Subkutaneöz Yerlesimli Siradisi Wohlfahrtia magnifica Vakasi.

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.

[Maggots in the wound, debridement, disinfection and wound healing]. / Vliegenmaden in de wond: débridement, desinfectie en wondgenezing.

An 87-year-old man had a longstanding untreated large basosquamous carcinoma on his right ear. He was admitted to the emergency department at our hospital. A large portion of the auricle had perished, together with part of the tumour. Surgery was planned but two days before, the patient complained of an irritating loud noise in his ear. We discovered this was caused by maggots in his external acoustic meatus: myiasis. Dozens of maggots were removed. A striking finding was that the smell of the wound had disappeared and that the wound was much cleaner, with a reddish aspect and less necrosis. The surgical procedure was uneventful. Larval therapy has been known for centuries. In recent years it has gained renewed interest as it may enhance wound debridement, wound disinfection, and may promote wound healing.

Aural-pharyngeal polyps associated with Cryptosporidium infection in three iguanas (Iguana iguana).

Cryptosporidium spp. infection was associated with aural-pharyngeal polyps in three iguanas (Iguana iguana). All iguanas were presented for masses protruding from the ear canal, and the disease was characterized by a chronic clinical course. The masses consisted of nests of cystic glands surrounded by abundant fibrous connective tissue and lined by hyperplastic cuboidal to pseudostratified columnar epithelium that was moderately to heavily colonized by cryptosporidial organisms. Electron microscopy revealed that the majority of organisms were trophozoites.

Pneumocystis carinii in the temporal bone as a primary manifestation of the acquired immunodeficiency syndrome.

Extrapulmonary infection with Pneumocystis carinii is rare and is usually associated with severe systemic illness. We report, in two patients, the histologic, ultrastructural, and monoclonal cell surface antibody identification of P carinii in otic polyps. Both patients had serum antibody to human immunodeficiency virus. These P carinii infections in the temporal bone are unusual in their location and in the apparent absence of associated pulmonary infection. This otologic presentation was the primary manifestation of the acquired immunodeficiency syndrome.
