Fig. 1 (A) The initial lesion is a subungual hyperkeratotic nodule on the right little fingertip. (B) A hyperkeratotic and crusted nodule is seen after laser treatment. (C) An erythematous swollen nodule is seen after wide excision.
Fig. 2 (A) Ultrasonography, (B) radiography, (C) magnetic resonance imaging, and (D) three-dimensional?밹omputed tomography images showing osteolysis at the distal edge of the distal phalanx. (E, F) Histopathological images of the wide excision specimen showing a large and bulbous hypertrophic epidermis with downward proliferation that is compressing the dermis without atypia (H&E; E: ×10, F: ×100). (G) An image from immunohistochemical analysis showing that positivity in basal layer and suprabasal cells for Ki-67 (Ki-67, ×100). (H, I) Histopathological images of the amputation specimen showing atypical squamous cell proliferation and osteolysis (H&E; H: ×10, I: ×100).
