Chromoblastomycosis
In a 28-year old cattle breeder from the State Apure / Venezuela developed in the course of two years a small ulcer on his left ear lobe, which is itching and had a thin crust. After the failing of several treatments the patient consulted a dermatologist. On his left cheek did grow, further, a fluctuating abscess.

Contact dermatitis
In a 20-year old farmhand a very painful inflammation began to appear on his left ear after painting a wooden fence with Karbolineum (a phenol product used to protect wooden fences). The surface of the reddened ear was smooth, but on the inside started to grow hemorrhagic, vesicle-like skin thickenings blocking the auditory canal.

Chromoblastomycosis
In the histological slide of the biopsy taken from the left earlobe was found under the atrophic epidermis a microabscess containing several fungus cells with a thick brown capsule. This tumor with a proper colour belongs to the group of Dematiaceae. See also the fungi with yellow-brown hyphae in the phaeohyphomycosis.
