Abstract

Ungual alterations in Hansen's disease may be observed in over 60% of the
patients and are characterized by subungual keratosis, onychogryphosis, mycronychia, anonychia, onychorrhexis, Beau's lines and ungual pterygium. Such alterations may be the consequent to the anesthesia caused by Hansen's disease peripheral neuropathy, repetitive trauma, peripheral vascular insufficiency, infections, and associated factors. The authors presented 4 lepromatous patients without previous treatment with diffuse infiltration in the fingers and toes, hiperplasia of the nail bed, thinned nail plate and onychorrhexis. Biopsy of the nail bed showed lepromatous infiltration with numerous acid fast bacilli. The authors suggested that the nail distrophies may be caused by pressure of the specific infiltration on the nail matrix.
