[A case of rhinofacial entomophthoromycosis in Soudano-Sahelian tropical climate in Burkina Faso]. / Un cas d'entomophthoromycose rhinofaciale en climat tropical soudano-sahélien au Burkina Faso.

We describe a rhinofacial entomophthoramycosis case in a sexagenarian (65 years old) housewife. She was immunocompetent and resident of Burkina Faso. She consulted both the service of dermatology and the service of stomatology of the Teaching Hospital of Bobo-Dioulasso in February 2016 for a diffuse facial tumefaction evolving over six months. This tumefaction was associated with headaches and a left nasal obstruction. Histological examination of the lesion showed an important and polymorphic inflammatory reaction. Also, a filamentous fungus with wide non-septated hyphae and right-angled fungal branching, consistent with mucormycosis was isolated. Mycological diagnosis based on fungal culture with Sabouraud medium without any antibiotic and cyclohexemide after incubation at 27°C and at 30°C was negative. Furthermore, it was not possible to amplify the DNA extracted from biopsy. Antifungal therapy based on the administration of fluconazole per os at 800mg/day was started allowing clinical improvement. This is the first case of a rhinofacial entomophtharomycosis documented in Bobo-Dioulasso. Rhinofacial entomophthoromycosis is largely unknown, even in tropical regions such as Burkina Faso. This lack of knowledge results in a delay in the diagnosis, and subsequently a bad prognosis. It is therefore urgent to improve knowledge on this disease to guide diagnostic steps, prognosis of outcome, and antifungal therapy.

Invasive aspergillosis in a user of inhaled cocaine: rhinosinusitis with bone and cartilage destruction.

Aspergillosis is an infection caused by saprophytic fungi of the genus Aspergillus, which typically occurs in immunosuppressed individuals, but has also been reported in immunocompetent patients. The main routes of entry are the respiratory tract, skin, cornea, and ear, and the infection may be localized or disseminated by contiguity or vascular invasion. We report a severe case of rhinosinusitis with cutaneous involvement, caused by invasive aspergillosis, in an immunocompetent user of inhaled cocaine. Invasive aspergillosis related to cocaine abuse has not yet been reported in the literature. After itraconazole treatment and surgical debridement, complete clinical remission was achieved. Nasal reconstruction with a skin graft over a silicone prosthesis resulted in a satisfactory esthetic outcome.

Case for diagnosis.

Hansen's disease is a chronic infecto-contagious disease caused by Mycobacterium leprae. The bacillus prefers low-temperature areas and the nose is usually the initial site of lesions. Transmission of the bacilli occurs by nasal and oropharyngeal secretions, and through solutions of continuity of the skin and/or mucosae. Nasal manifestations are found in the later stages of the disease.

Mucocutaneous entomophthoramycosis acquired by conjunctival inoculation of the fungus.

Entomophthoramycoses are classified into subcutaneous, mucocutaneous, and primary visceral forms. The mucocutaneous form, also known as rhinoentomophthoramycosis, involves the mucosa and subcutaneous tissues of the nose and is caused by Conidiobolus coronatus (Entomophthora coronata). In this report, we describe the first case of mucocutaneous entomophthoramycosis acquired by introduction of the fungus through the conjunctival mucosa as a consequence of trauma involving contamination with soil. The patient was a 37-year-old man with no other complaints. The lesion was tumoral and extended into the ethmoidal and maxillary sinuses. The histopathologic appearance of the lesion was characteristic of this infection with a granulomatous process rich in eosinophils and with hyphae surrounded by an eosinophilic, periodic acid-Schiff stain-positive halo (Splendore-Hoeppli phenomenon). To the best of our knowledge, this case constitutes the first report of mucocutaneous entomophthoramycosis acquired by ocular contamination.

[Entomophthoramycosis (zygomycosis) caused by Conidiobolus coronatus in Mato Grosso (Brazil): case report]. / Entomoftoromicose (zigomicose) causada por Conidiobolus coronatus em Mato Grosso (Brasil): relato de caso.

Zygomycosis is a subcutaneous mycosis caused by soil fungi, such as Conidiobolus coronatus. In general, the main clinical manifestation is a chronic rhinofacial tumor. We report the first case of zygomycosis (entomophthoramycosis) caused by Conidiobolus coronatus, occurring in Mato Grosso, West Brazil.

Entomoftoromicose (zigomicose) causada por Conidiobolus coronatus em Mato Grosso (Brasil): relato de caso / Entomophthoramycosis (zygomycosis) caused by Conidiobolus coronatus in Mato Grosso (Brazil): case report

Zigomicoses são micoses subcutâneas causadas por fungos do solo, que geralmente manifestam-se como uma infiltração granulomatosa crônica da submucosa nasal, estendendo-se para o tecido subcutâneo e pele da face. Descreve-se aqui o primeiro caso de zigomicose nasofacial causada pelo Conidiobolus coronatus, ocorrendo em Mato Grosso, Brasil.

Entomophthoramycosis by Conidiobolus coronatus. Report of a case successfully treated with the combination of itraconazole and fluconazole.

Rhinoentomophthoramycosis caused by Conidiobolus coronatus in a 61-year old woman was unsuccessfully treated during 8 years with all the antifungals available in the Brazilian market, including potassium iodide for 1 month, sulfamethoxazole plus trimethoprim for 2 months, amphotericin B, total dose of 1130 mg, cetoconazole, 400 mg/day for 6 months, fluconazole, 200 mg/day, for at least 2 months and, itraconazole, 400 mg/day for 2 months, followed by 200 mg/day for 4 more months. Complete clinical and mycological cure was achieved using itraconazol 400 mg/day in association with fluconazol 200 mg/day during 24 months. After cure she was submitted to plastic surgery to repair her facial deformation. Today she remains clinically and mycologically cured after 59/60 months (5 years!) without any specific antifungal. We thus suggest the use of the combination of itraconazole and fluconazole as an additional option for the treatment of this mycosis.

Rhinofacial zygomycosis caused by Conidiobolus coronatus: a case report including in vitro sensitivity to antimycotic agents.

A case of zygomycosis caused by Conidiobolus coronatus, occurring in a 31-year-old priest from the Ivory Coast, is reported. Lesions eventually resolved after 2 1/2 years, during which the patient was variously treated with intravenous amphotericin B and miconazole as well as surgical resection. It is difficult to be certain which, if any, of these treatments contributed to resolution of lesions. A report of in vitro sensitivity data to a variety of antifungal agents is included.

[Rhinoentomophthoramycoses. Report of 4 cases]. / Rinoentomoftoramicose. Apresentaçao de quatro casos.

Four cases of rhynoentomophthoramycosis are reported from urban areas of the states of Bahia and Maranhão, Brazil. The lesions presented with infiltration, redness and heat of the skin of the nose and infraorbital areas and accompanying nasal stuffiness. In on case the infiltration also involved the lips and mandibular area causing severe facial deformity. Microscopically, granulomatous reactions with small abcesses, fibrosis and a dense infiltration of eosinophils were found. Hyphae were seen frequently, always associated with the Splendore phenomenon. Three cases were treated completely with iodine. The one case resistant to iodine was cured with prolonged administration of sulphona. In two cases, plastic surgery was performed for facial reconstruction and nasal-unblocking respectively. Including the cases presented here, only 8 cases of rhynoentomophthoramycosis have been reported in Brazil, but the authors believe that this pathology muta occur more frequently. The lack of knowledge of its clinico-pathological aspects may be responsible for the delay or lack of diagnosis of this entity which occurred in two of the cases reported here.
