Correct Answer-D
The lines of Blaschko are defined by a pattern determined by nevoid
representing non random lines on the human skin or mucosa
Blaschko lines or the lines of Blaschko are thought to represent
pathways of epidermal cell migration and proliferation during the
development of the fetus.
Lines of Blaschko represent non-random developmental lines of the
skin fundamentally differing from the system of
dermatomes. They follow a'V' shape over the back, 'S' shaped
whorls over the chest, stomach, and sides, and wary shapes on the
head. The lines are belived to trace the migration of embryonic
epidermal cells. The stripes are a type of genetic mosaicism
These lines characteristically do not follow the underlying nervous
Vascular, muscular or lymplatic structures in the
skin. Lines of Blaschko are not ordinarily visibk, but are recognized
in several cutaneous disorders that follow these arallel streaks.

Correct Answer-D
Ans. D. i.e. Tzanck smear from the floor of bulla
Correct Answer-D
Pulsed dye Laser REF: Roxburgh's common Skin Diseases 17th
edition page 194 & 205, Clinical Dermatology by John Hunter, John
Savin & Mark Dahl 3' edition page 275
"Selective Photothermolysis or Pulsed dye laser is the treatment of
choice for Portwine hemangioma"
Port-wine stains are crimson blotches in which there is marked
capillary dilatation compared to a capillary angioma, which is a red
nodule or plaque containing proliferating endothelial cells. The latter
tend to flatten and disappear at puberty. Larger ones may cause
problems from bleeding and/or erosion. Cavernous haemangiomata
are larger and compressible, containing large vascular spaces
Occasionally a port-wine stain of the trigeminal area is associated
with a vascular malformation of the leptomeninges on the same side
which may cause epilepsy or hemiparesis (the SturgeWeber
syndrome), or with glaucoma.
Excellent results have been obtained with careful and time-
consuming treatment with a 585-nm flashlamp-pumped pulsed dye
laser. Treatment sessions can begin in babies and anaesthesia is
not always necessary. If a trial patch is satisfactory, 40-50 pulses
can be delivered in a session and the procedure can be repeated at
3-monthly intervals.
