ABSTRACT
Abstract Pseudomycetoma is an extremely rare deep mycosis, caused by dermatophytic fungi that penetrate the tissue from infected follicles of tinea capitis. Both clinically and histopathology are similar to eumycetoma, being distinguished through the isolation of the fungus, which in the case of pseudomycetoma can be Microsporum spp. or Trichophyton spp. genre. We present a 24-year-old man with an exuberant tumor in the occipital region with fistula, whose histopathological examination evidenced grains composed of hyaline hyphae and the culture for fungi isolated the agent Microsporum canis. Combined treatment of surgical excision followed by oral griseofulvin for two years was performed, with resolution of the condition.

Acremonium infection is rare and associated with immunosuppression. A case of recurrent cutaneous Acremonium infection after short term voriconazole use is described. Surgical resection was the definitive therapy. Oral voriconazole was used in the treatment of Acremonium infection, but recurrence was associated with short therapy. Prolonged antifungal therapy and surgical resection are discussed for the treatment of localized lesions.
Infecção por Acremonium é rara e pode estar associada com imunossupressão. Descrevemos um caso de infecção recorrente de pele por Acremonium após tratamento breve com voriconazol. Ressecção cirúrgica foi o tratamento definitivo. Terapia prolongada com antifúngicos e ressecção cirúrgica são discutidas para o tratamento de doenças fúngicas localizadas.

A case of subcutaneous phaeohyphomycosis caused by Cladophialophora sp. is reported. The patient, an immunosuppressed host presented a nodule on the dorsum of the right hand which relapsed four months after excision. Dematiaceous septate hyphal and yeast like elements were seen in mycological and histological examination. The isolated fungus was identified on the basis of micro-macromorphological and physiologic characteristics.
É descrito caso de feohifomicose subcutânea causada por Cladophialophora sp. O paciente, imunossuprimido, apresentou nódulo no dorso da mão direita que recidivou quatro meses após excisão. Os exames micológico e histopatológico evidenciaram hifas septadas demácias e células leveduriformes. O fungo foi identificado com base no estudo micro-macromorfológico e fisiológico.

Sao descritos três casos de feo-hifomicose subcutânea, os primeiros encontrados no Estado do Pará, todos oriundos de localidades situadas a leste de Belém, nas microrregioes do Salgado e Bragantina. O diagnóstico teve por base o reconhecimento dos parasitos em cortes histológicos, sem identificaçao de espécie, uma vez que todo o material disponível para exame - compreendendo as lesoes completamente excisadas -, ao ser recebido, já estava fixado em formol e imprestável, portanto, para qualquer tentativa de estudo micológico. A abundância de elementos fúngicos verificada nos tecidos, após impregnaçao pela prata (métodos de Grocott e de Fontana-Masson), contrastava com a dificuldade para visualizá-los em cortes nao-corados ou corados por hematoxilina-eosina, fato devido certamente ao aspecto das hifas neles existentes: delgadas, de paredes finas e cor quase imperceptível.
