case_images: 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).
case_images: Seven days after biopsy, the lesion evolved with fistula formation and
  drainage of yellow-white exudate and lumpy material

case_images: Seven days after biopsy, the lesion evolved with fistula formation and drainage of yellow-white exudate and lumpy material (Figure 2).
case_images: 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

case_images: 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).
case_images: The direct examination of the lumpy material sent to medical mycology
  laboratory showed the presence of spiculated structures compatible with
  crystal deposits
