[Mycotic disease of the mucous membranes of the head and neck].
BACKGROUND
Candidiasis is usually a superficial infection of the moist areas of the body and is generally caused by Candida albicans. Visceral infections occur in diabetes, lymphomas and leukemias, malnutrition, avitaminosis and they are associated with antibiotic, corticosteroid and immunosuppressive therapy. Candida albicans was isolated from middle ear inflammation. The diagnosis is made on the basis of microscopic appearance of colonies and characteristic smell. Candidiasis is successfully treated with nystatin, imidazol derivatives (fluconazole, ketoconazole and intraconazole), amphotericin B, 5-fluorocystosine and 1% iodine solution.


METHODS
This is a case report of a 46-year-old patient with a persistent nasal, sinus and ear infection of unknown origin. The patient first received antibiotic and steroid therapy and trepanation of the right maxillary sinus was performed. As the patient's condition aggravated with increase of temperature and bad laboratory findings, he was hospitalized. Radiography revealed a pathological process in both maxillary sinuses and both mastoids, so mastoidectomy and left maxillary sinus trepanation were performed. Histopathological examination of the right mastoid revealed a mould infection. The immunologic status pointed to hypogammaglobulinemia IgG. The following diseases were excluded: systemic diseases, blood diseases, Reiter's syndrome, AIDS, Hepatitis B, other viral diseases, toxoplasmosis, trichinellosis, borreliosis, typhus, paratyphus and exanthematous typhus. The diagnosis of candidiasis caused by Candida crusei and Candida kefyr was made on the basis of macroscopic and microscopic findings and biochemical identification. Ketoconazole was introduced (400 mg/per day) as well as high doses of vitamins and povidone-iodine locally. After a period of remission the patient died due to myocarditis, sepsis, acute kidney failure associated with severe mucosal necrosis of the mouth, esophagus and throat. Differential diagnosis in fever of unknown origin must include the possibility of mycotic infection, whereas the therapy of mycotic diseases must include two antimycotics at the same time.


CONCLUSIONS
Candida albicans is often found in the oral cavity and skin as well as in intestines of 18% of healthy subjects. It is unknown why it causes clinical illness. Antibiotic therapy of bacterial infections enables candida colonization especially in immunosuppressed patients. In our patient two types were found: Candida krusei and Candida kefyr. It is of special importance to perform differential diagnosis in cases with fever of unknown origin in order to include the possibility of mycotic infections, whereas treatment of systemic fungal infections requires a team of physicians.
