A 76-year old patient from the State Apure/ Venezuela refers that the dark tumor in his face grew slowly for several years. It was considered a birth mark, was painless and not itching.

Chromoblastomycosis
The biopsy shows a pseudoepitheliomatous hyperplasia of the epidermis and a non-specific inflammation with giant cells and microabscesses. Fungal cells are very difficult to see at this magnification and in this HE stained slide.

Basalioma
The pigmentation may be detected clearly with the microscope.

Fig.30-A3
Chromoblastomycosis
With higher power small clusters of fungus cells were observed which had a brownish capsule. The multiplication of these fungi in tissues occurs by septation and not by budding as it is seen in the yeast-like cells in other mycoses. Septa are not well seen in this.
