In a review of 61 consecutive autopsy cases with a hematologic malignancy, said cases extending from April, 1984 to August, 1989, 34 cases were documented to have had an invasive fungal infection. The highest rate of incidence was found in various leukemia cases (69 to 100%), followed by those who had had a malignant lymphoma (50%) and a multiple myeloma (33%). Cultures from autopsy materials that determined the presence of a fungus were positive in 21 cases, including 13 cases of candidiasis, 8 cases of aspergillosis, and 2 cases of geotrichosis. The most frequent site of the fungal infection was in the lungs (76%), followed by the GI tract, the kidneys, the liver, and the spleen. Of 36 cases that had been treated with an empiric antifungal therapy, an invasive fungal infection was documented in 22 cases, half of them being fatal. In contrast, of 20 cases that had not received any antifungal treatment prior to death, an invasive fungal infection was found in 8 cases and three of these were fatal.

It is interesting and useful to review the different mycoses which can affect oral and maxillofacial tissues. In this review, all mycoses which can involve these tissues are described, based on a simple classification into superficial and deep mycoses. The superficial mycoses described are the dermatophytoses, Tinea, the piedra, but also the candidiasis, which are superficial opportunistic infections. The deep mycoses are subdivided into subcutaneous, systemic, and opportunistic mycoses. Subcutaneous fungal infections are sporotrichosis, lobomycosis, rhinosporidiosis, entomophthoromycosis, and chromomycosis. Systemic fungal infections are paracoccidioidomycosis, blastomycosis, cryptococcosis, histoplasmosis, histoplasmosis duboisii, and coccidioidomycosis. Opportunistic mycoses are aspergillosis, mucormycosis, geotrichosis, torulopsosis (considered nowadays as a candidiasis), basidiomycosis, cephalosporiomycosis, alternariosis, cercosporomycosis, paecilomycosis, and fusariomycosis. Eumycotic mycetomas are also cited.

In a study of 450 Amazonian anurans, we isolated yeasts and yeast-like fungi from 54 animals (Bufo granulosus, B. marinus, Dendrophrynyscus sp., Hyla geographica, H. lanciformes, Ololygon rubra, Adenomera hylaedactyla, Eleutherodactylus fenestratus, Leptodactylus fuscus, L. ocellatus, L. pentadactylus). The internal organs of these animals did not show any macroscopic anomaly nor histopathology. We recovered 105 fungal isolates from the anuran liver, lung, kidney, spleen, heart and gonad. The isolates were made up of 30 fungal species, 9 of which (48 isolates, 46%) were fungi with known pathogenic potentials, namely: Candida guilliermondii, C. parapsilosis, C. tropicalis, C. glabrata, Geotrichum candidum, Aureobasidium pullulans, Wangiella dermatitidis, Trichosporon cutaneum and Exophiala werneckii. Eleven animals harbored identical fungi in more than one of their internal organs; seven animals had more than one fungal species colonizing a single organ. Our findings indicated probable natural subclinical infections of candidiasis, geotrichosis or phaeohyphomycosis, and also symbiotic presence of non-pathogenic fungi among neotropical anurans.

Lesions of candidiasis, mucormycosis (phycomycosis), entomophthoramycosis, geotrichosis, cryptococcosis, paracoccidioidomycosis and coccidioidomycosis have been reported in the alimentary tract of nonhuman primates. Candidiasis and mucormycosis were reported most often. Both Old and New World monkeys and great apes are susceptible; infection is rare in prosimians. Ulcers and necrosis of the mucosa of the alimentary tract are the principal gross lesions. A granulomatous inflammatory process occurs in which the fungi are visible histologically on hematoxylin and eosin (HE)-stained sections, but they are seen and characterized better when stained with periodic acid-Schiff (PAS) or Gomori methenamine silver (GMS) techniques. Cultural or immunofluorescence studies, or both, are necessary for specific identification of the fungi. Immunosuppression is suggested as a predisposing factor in certain mycotic diseases.

The type of fungal infection and the immunologic status of the patient determine whether drug therapy should be used. Amphotericin B is the single most important antifungal agent for the treatment of systemic mycoses. Flucytosine is given adjunctively with amphotericin B. Miconazole, a new parenteral agent, may be useful in treating candidiasis, cryptococcosis, paracoccidioidomycosis and coccidioidomycosis. Potassium iodide is used to treat lymphocutaneous sporotrichosis, bronchopulmonary geotrichosis and chromoblastomycosis. Nystatin, tolnaftate, clotrimazole and haloprogin are used for mucocutaneous infections. Griseofulvin is limited to the treatment of skin and nail infections caused by dermatophytes.

Geotrichosis affects mainly patients with systemic diseases like diabetes mellitus, leukoses, neoplasms etc. Clinically, it is similar to candidiasis and may occur as an oral, vaginal, skin, or systemic infection. Clinical specimens (98 sputa and 67 oral smears) were collected and studied using microscopic examination of Gram stained preparations and culture sampling between 1995 and 1997. Geotrichum candidum was isolated as a single pathogen in 8 sputum and 7 oral smear samples. Ten-day antifungal treatment with Nizoral was applied and resulted in relatively quick clinical improvement. The presented cases are the first cases of pulmonary and oral infections reported in our home practice in which Geotrichum candidum species was identified as a pathogen. The identification of Geotrichum candidum using combination of colonial and microscopic morphologic features increase the possibilities for diagnostic decision.

The mechanisms of immunity and allergy, at play in every infectious disease, must be comprehended before the pathogenesis of an infection can be appreciated.Immunity, allergy and serology are concerned with specific antigen-antibody reactions. In immunity the principal concern is with the final disposition of antigen (agglutination, lysis, and phagocytosis). In allergy attention is focused upon tissue damage resulting from antigen-antibody union. In serology interest is devoted to the presence of antibody as evaluated by certain visible in vitro reactions-precipitin, agglutination, opsonization and complement fixation tests. There are two types of allergic reaction-the immediate or anaphylactic type and the delayed type or the allergic disease of infection. Neither kind takes part in the mechanism of immunity. At this time the allergic antibody and the immune antibody must be considered as two different and distinct antibodies. Skin and serologic tests are important diagnostic aids in certain pulmonary mycotic infections-for example, coccidioidomycosis, blastomycosis, histoplasmosis and moniliasis. Clinical expressions of allergy may appear in coccidioidomycosis, histoplasmosis and moniliasis. Pulmonary mycoses are divided into three groups, that is, the endogenous mycoses (actinomycosis, moniliasis, geotrichosis), the endogenous-exogenous mycoses (cryptococcosis, aspergillosis, mucormycosis) and the exogenous mycoses (nocardiosis, coccidioidomycosis, histoplasmosis, North American blastomycosis). The diagnosis and treatment of the important mycotic infections that invade lung tissue are discussed.

Invasive fungal infection (IFI) causes morbidity and mortality among patients with hematological malignancies who receive cytotoxic chemotherapy or hematopoietic stem cell transplantation (HSCT). We evaluated the incidence and treatment outcomes of proven and probable IFI in 22 institutions between 2006 and 2008 following the recent European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) consensus criteria. We analyzed 2,821 patients with hematological malignancies, including 597 who had undergone HSCT; these included patients with acute leukemia (n = 697), myelodysplastic syndrome (n = 284), lymphoma (n = 1465), or multiple myeloma (n = 375). IFIs were diagnosed in 38 (1.3%) patients (18 proven and 20 probable), including 20 patients who underwent HSCT and 18 who received chemotherapy alone; these included patients with aspergillosis (n = 23), candidiasis (n = 6), mucormycosis (n = 6), trichosporonosis (n = 2), and geotrichosis (n = 1). The incidence of IFI was 5.4 % in allogeneic HSCT patients, 0.4 % in autologous HSCT patients, and 0.8 % in patients receiving chemotherapy alone. Eighteen patients with aspergillosis were diagnosed with probable pulmonary IFI as determined by computed tomography scan and positive galactomannan assay. Overall, antifungal targeted therapies resulted in successful outcomes in 60.0 % of patients. IFI-attributable mortality rate was higher in HSCT patients than in those receiving chemotherapy alone, but the difference was not statistically significant.

Opportunistic yeast infections are diseases caused by fungi which normally are saprophytic and do not cause disease in humans or animals. The prevalence of these diseases has been increasing due to immunosuppressive, corticosteroid, and long-term antibiotic treatment following organ transplantation or after serious metabolic, hematological, or immunological diseases. We review epidemiological, clinical, diagnostic, and therapeutic aspects of the four "big" opportunistic yeast infections: candidiasis, cryptococcosis, trichosporonosis, and geotrichosis.
