S. Oliwiecki et al., SUBUNGUAL KERATOACANTHOMA - A REPORT OF 4 CASES AND REVIEW OF THE LITERATURE, Clinical and experimental dermatology, 19(3), 1994, pp. 230-235
Subungual keratoacanthoma is a rare benign neoplasm which most commonl
y occurs in middle-aged Caucasians. It usually presents as a painful,
rapidly growing lesion of the terminal phalanx. Radiography consistent
ly demonstrates a well-defined cup-shaped erosion of the underlying bo
ne. Clinically, subungual keratoacanthoma must be distinguished from s
ubungual squamous carcinoma. We report four further cases and discuss
the literature.
