Figure

  • Fig. 1 (A) Greenish brown chromonychia was seen on the proximal and lateral nail plate on the right middle finger. (B) The nail plate was extracted and two 2 mm punch biopsies were performed on the proximal nail fold and distal nail matrix (arrow). (C) The extracted nail plate showed green to brown-colored pigmentation.

  • Fig. 2 (A) Histopathologic findings of the proximal nail fold revealed no significant inflammation suggesting paryonychia (Hematoxylin and eosin, ×40). (B) The biopsy specimen from the distal nail matrix showed dilated capillary proliferation in the papillary dermis (Hematoxylin and eosin, ×40). (C) The endothelial layer was positivity for CD34 (CD34, ×200). (D) Small granules were positive for Prussian blue stain (Prussian blue, ×200).
