However, his main complaint at that time was pain, volume increase, and severely swollen softened lesion on the side of the left foot, with a 6-month period evolution (Figure 1).

Seven days after biopsy, the lesion evolved with fistula formation and drainage of yellow-white exudate and lumpy material (Figure 2).
Histological examination with hematoxylin-eosin showed hyperkeratosis and
acanthosis in the epidermis. The dermis revealed thickened collagen with
infiltration of mononuclear cells around the vessels and the presence of
amorphous material, with a lightly eosinophilic appearance, surrounded
by coarse bands of collagen tissue

The dermis revealed thickened collagen with infiltration of mononuclear cells around the vessels and the presence of amorphous material, with a lightly eosinophilic appearance, surrounded by coarse bands of collagen tissue (Figure 3).
The direct examination of the lumpy material sent to medical mycology
laboratory showed the presence of spiculated structures compatible with
crystal deposits
