ABSTRACT
Abstract In some cases, keratoacanthomas can be indistinguishable from squamous cell carcinoma, making the gold standard treatment surgical excision with histopathological evaluation. The surgical defects created on the back of the hand can be challenging to repair. We describe the use of bilateral rotation flap as an option in this area, and discuss the indications and contraindications of some of the possible surgical techniques for reconstruction of the dorsum of the hand.

Subcutaneous phaeohyphomycosis is an infection caused by dematiaceous fungi which mainly affects immunosuppressed patients. We report a case of subcutaneous phaeohyphomycosis on the back of the left hand in a kidney transplant patient who had been taking prednisone, tacrolimus, and azathioprine daily for 3 years.

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.
