Abstract

Acquired digital fibrokeratoma is an uncommon, benign fibrous tumor which usually occurs in adults as a solitary lesion. The most frequent locations are fingers and toes and the size of the tumor is generally small, around 3~5 mm. An 18-year-old female presented with a solitary, skin-colored, round and protruded nodule of the left great toe. The size of nodule was 2.5x1.6x1.4 cm. Histopathologic examination revealed typical findings of acquired digital fibrokeratoma. Herein, we report a giant acquired digital fibrokeratoma.

Figure

  • Fig. 1 Skin-colored, 2.5×1.6×1.4 cm sized, solitary, round and protruded nodule on the lateral side of the left great toe.

  • Fig. 2 (A) Histopathologic examination demonstrated a dome-shaped tumor consisting of a thick core lesion and peripheral lesion (H&E, ×4). (B) The core of tumor showed thick dermal collagen bundles oriented along the longitudinal axis of the lesion (H&E, ×40). (C) The peripheral lesion of tumor showed irregular acanthosis, thickening of rete ridges and increased capillaries (H&E, ×40). (D) The close-up view of the peripheral lesion showed thin walled dilated capillaries and thick collagen bundles in dermis (H&E, ×100).
