Case Report
17 years old male presented to our OPD with history of whitening of his
finger and toenails. The nail changes started as ill-defined white
discoloration on few finger and toenails which gradually and
synchronously progressed to almost total whitening of all the twenty
nails over 3 years. The growth of the nails was otherwise normal. He was
born out of a non-consanguineous marriage. His developmental milestones
were normal. He had no previous medical or surgical history. He denied
history of any medications, exposure to chemicals or mechanical trauma
to the nails. There was no history of leukonychia or other dermatologic
diseases in family.
On physical examination, partial to total leukonychia of all finger and
toenails was observed. Few nails had a totally white discoloration. Most
of the nails had a pink transverse band about 2- 3 mm wide at the distal
edge. The nail folds and cuticles were normal. The nail surface was
smooth with no pitting, crumbling or nail thickening (Figure
1). On applying pressure on the nail plate, white color did not
disappear. Thorough systemic examinations did not reveal any
abnormalities.
