    Description / Table of Contents: Summary Despite the availability of modern antimycotics, which produce high cure rates in early infections, the therapy of advanced chromoblastomycosis is still unsatisfactory. An initial chromoblastomycosis caused by a hitherto unidentified species of the genus Phialophora was diagnosed in a 46-year-old teacher. The organism was isolated twice at an interval of 6 weeks from a partly psoriasiform, partly verrucous lesion on the 4th toe. The infection was apparently acquired 4 years ago during a holiday at Cape Verde. Treatment with itraconazole (Sempera), 200 mg/day, and amphotericin B (Ampho-Moronal) cream for 6 weeks initially resulted in rapid regression. However, 4 weeks after cessation of therapy, the Phialophora species was cultured again from skin scrapings. Complete healing was achieved after re-treatment with itraconazole for 20 weeks at the same dosage in combination with topical amorolfine and local hyperthermia. Until now, no relapse has occured. The present case demonstrates that this rare disease, which mainly occurs as a traumatic mycosis in the rural population of tropical regions, must be included in the differential diagnosis of psoriasiform or verrucous skin lesions and also included in the list of diseases which may be acquired while on vacation in exotic locations.
    Notes: Zusammenfassung Die Therapie der fortgeschrittenen Chromoblastomykose ist trotz moderner Antimykotika immer noch unbefriedigend, während die Behandlung im Frühstadium hohe Heilungsraten erwarten läßt. Bei einem 46 Jahre alten Lehrer konnte eine initiale Chromoblastomykose durch eine noch unbekannte Spezies der Gattung Phialophora diagnostiziert werden. Der Erreger wurde 2mal im Abstand von 6 Wochen aus einem teils psoriasiformen, teils verrukösen Herd an der 4. Zehe isoliert, die Infektion ist vermutlich im Rahmen eines Badeurlaubs 4 Jahre zuvor auf Cap Verde acquiriert worden. Unter 6wöchiger Therapie mit Itraconazol (Sempera) 200 mg/Tag und einer Amphotericin-B-haltigen Zubereitung (Ampho-Moronal-Creme) kam es bei guter Verträglichkeit zunächst zu einer raschen Rückbildung des Hautbefunds. Vier Wochen nach Therapieende ließ sich der Erreger jedoch erneut aus Schuppenmaterial anzüchten. Eine nochmalige, nun 20wöchige Itraconazoltherapie in obiger Dosierung führte in Kombination mit topischem Amorolfin und lokaler Hyperthermie zu einer nun vollständigen, rezidivfreien Abheilung. Der vorliegende Fall zeigt, daß diese seltene Erkrankung – als Verletzungsmykose vornehmlich bei der Landbevölkerung tropischer Regionen auftretend – auch als sog. Urlaubsdermatose im Zug des Ferntourismus in die Differentialdiagnostik psoriasiformer oder verruköser Hautveränderungen einbezogen werden muß.

    Notes: Abstract Depending on the aggressiveness of the pathogen and a patient’s immunocompetence, fungal polypoid pansinusitis or allergic fungal sinusitis (AFS) may be a life-threatening disease. Apart from the clinical findings, its diagnosis is based on the demonstration of mucinous material with abundant eosinophils in the paranasal sinuses (indicating an allergic process), cultivation of the causative pathogen and immunocompetence of the patient. In a 20-year-old immigrant Sudanese woman, AFS due to Bipolaris (Drechslera) hawaiiensis was diagnosed. Because of intracranial extension, the disease had led to erosion of the cranial base and orbit with amaurosis on the right side and focal epilepsy. In addition to endonasal microsurgical pansinus operations, local irrigation therapy with amphothericin B was accompanied by systemic treatment with itraconazole after in vitro cultivation of the pathogen and determination of its sensitivities. Interdisciplinary management included a combination of endonasal surgery with debridement of infected tissues and wide drainage of the sinuses without removal of skull bone or the dural lesion in addition to specific antimycotic treatment. Injury to adjacent anatomical structures must be avoided in any case to prevent systemic or possibly lethal dissemination of infection.

    Notes: Abstract A 13-year-old Moroccan boy in The Netherlands developed fever and a lesion resembling ecthyma gangrenosum on the abdomen during cytostatic drug treatment for a lymphoblastic B-cell lymphoma.Scytalidium dimidiatum was cultured from blood and the abdominal skin lesion. The patient was successfully treated with amphotericin B. The fungusScytalidium dimidiatum is a fairly common plant pathogen in tropical and subtropical countries and is known to cause dermatomycoses in humans in these areas. This case demonstrates that it is necessary to be aware that immigrants from these areas can import their own fungal flora, some members of which may cause life-threatening disease in the case of patients with immune suppression.

    Notes: Abstract The case is described of a 42-year-old patient with acute myeloid leukemia who received two courses of chemotherapy complicated by prolonged bone marrow depression. He was admitted to hospital with fever, hepatosplenomegaly and bilateral nodular pulmonary infiltrates. After admission diffuse cutaneous skin nodules, and hypodense lesions in the hemispheres and cerebellum developed. Cultures of cerebrospinal fluid, bronchoalveolar lavage fluid, skin biopsy specimens and blood revealedScedosporium prolificans, indicative of disseminated mycosis. Treatment with amphotericin B and fluconazole was unsuccessful and the patient died within five days after admission. Features that may enhance early recognition ofScedosporium prolificans infection by both clinicians and microbiologists, as well as options in the treatment of infection with this fungal agent are discussed.

    Notes: Abstract Mycelial development of seventy-three strains of black yeasts and related fungi were studied, and numbers of nuclei per hyphal cell were counted. Two main patterns were apparent in expanding hyphae, viz. (1) uninucleate expanding hyphal cells, septum formation strictly following mitosis, and (2) multinucleate, branched, aseptate hyphal tips, septa being formed in a later stage, leading to oligo- or uninucleate mature cells. Characteristic genera in the two groups areExophiala andAureobasidium, respectively. InZasmidium and in someRamichloridium species all mycelial cells are oligonucleate. The character is indicative for relationships at the family level in black yeasts.

    Notes: Abstract The anamorph life cycle of the black yeastExophiala (Wangiella) dermatitidis is described. The fungus is dimorphic, yeast cells being the prevalent form of propagation. The fungus is strongly hydrophilic, probably completing its anamorph life cycle in submersion. Adaptation to dry conditions is slow. Types of conidiogenesis comprise annellidic, phialidic and sympodial reproduction, in addition to isotropic development. Phialoconidia fail to germinate under the conditions tested, and thus may have a function other than dispersal. Sterile, multicellular bodies resembling aCapronia teleomorph are described.

    Notes: Abstract Freeze-fracturing of outer wall layers ofCladosporium conidia revealed two types of ultrastructure, coinciding with taxonomic characteristics. The outer conidial layers were essentially smooth in the human pathogenic species,C. bantianum, C. carrionii, andC. trichoides. In contrast, mosaic arrays of rodlets on conidia were observed with freeze-fracturing in the saprobic species,C. cladosporioides, C. coralloides, C. herbarum, C. sphaerospermum, andC. variabile. Conidia ofC. elatum were an exception among the saprobic species as they had smooth surfaces. The present study supports the suggestion that the human pathogenicCladosporium species should be transferred to another genus.

    Notes: Abstract Taxonomic markers for differentiation of the anamorph genera Aureobasidium, Hormonema and Kabatiella were developed using PCR-ribotyping with the primers 5.8S-R and LR7 for amplification and the restriction enzymes Alul, DdeI, Hhal, MspI and RsaI for digestion. Aureobasidium and Hormonema are optimally differentiated with MspI; DdeI is particularly useful to distinguish aureobasidium, Kabatiella and Selenophoma. Relationships of the anamorph genera Aureobasidium, Hormoneng and Kabatiella with the teleomorph genera Pringsheimia and Dothiora are discussed.

    Notes: Abstract Trimmatostroma abietis from the needles of conifers and from stone, mostly in Germany, is described. On the natural substrate it is characterized by stromatic conidiomata. Conidia are mostly two-celled, are arranged in long chains, and originate by intercalary dilatation of fertile hyphae. The wide morphological plasticity of the fungus and its physiological profile are described. Its occurrence as a saprophyte and possibly opportunistic pathogen on plants and as an invader of environments with low water activity, particularly stone surfaces, are discussed. Relationships with other taxa are outlined.
