ABSTRACT
INTRODUCTION As many as 10% of patients seek dermatologic care for a nail disorder and it is essential that a knowledge of nail anatomy be clearly understood. Approximately, half of all nail problems are due to fungal infection and the remainder to psoriasis, lichen planus, tumors, ingrown nails, and a large miscellaneous group. Unlike the skin, where diagnoses are facilitated by changes in color, size, and shape, the spectrum of clinical expression for nail conditions is limited. Consequently, a number of diagnostic procedures must be performed more frequently on the nail than on the skin. It is important therefore that the dermatologist be familiar with nail surgery. In addition, the important functions of the nails must be taken into account when one considers performing nail surgical procedures: protection of the distal digit, facilitation of manual dexterity, and cosmesis.
