Progressive macular hypomelanosis (PMH) presents as asymptomatic, ill-defined hypopigmented
macules and patches on the trunk and back.

lichen striatus with minimal papules has been termed "lichen striatus albus." Nail lichen striatus may present as onycholysis or Assuring of nails, present as an isolated finding, or more commonly in association with concurrent affected skin.
Since our case had multiple cardiac rhabdomyomas, hypopigmented

Neuroimaging revealed a ring enhancing lesion in the right parietal lobe, while a fundus examination showed a hypopigmented
area in the left retina halfway between the fovea and optic disc.
to depigmented macules present over fingertips (Figure 2), forearms, groins and penis.

On his back, some hypopigmented
lesions from scarring remained, but these are expected to improve over time.
There was a significant association between scar length [odds ratio (OR): 1.54, 95% confidence interval (CI): 1.1-2.2; p=0.02], depressed scar (OR: 9.3, 95% CI: 3.2-27.2; p<0.001), hypopigmented
scar (OR: 0.01, 95% CI: 0.003-0.11; p<0.001) and the amount of intraabdominal adhesions.
His physical examination showed that he had a large number of hypopigmented
, round, smoothly contoured, and not raised lesions in his neck and back and flat warts on his dorsum of the hand bilaterally.
