A patient from Barinas / Venezuela came to a doctor presenting a small red nodule on her upper arm. She reported to have been bitten some weeks ago by an insect. She remembered well this incident, because it was very painful. On this spot developed then this slowly growing nodule.

This skin tumor was found in a patient on his upper arm. It was growing very slowly.

The skin nodule was completely resected and examined histologically. A so called mixed inflammatory reaction was found. A granuloma with a giant cell is seen in this picture.

Quite a few slides were examined histologically and roundish cells with a thick, yellow-brownish capsule were detected, i.e. a fungal infection was present. Especially it is of interest, that the patient was inmunologically suppressed, because she had a malignant tumor. Probably this is the reason that an opportunistic infection took place so easily. Neither in the literature nor during our long activity in the tropics did we find a case of this fungal infection after an insect bite.
