A young girl in her teens presented to
us for evaluation of well‑circumscribed,
irregularly shaped, mauve to tan colored,
smoothvelvetysurfacedplaquemeasuring
7 × 4.5 cm in a segmental conguration
extending from the zygomatico‑temporal
region up to the philtrum over the
left cheek [Figure 1a], progressively
increasing in size and coverage for the
past eight years. On a closer look at the
lesion, it was seen to be surmounted by
a solitary, irregular, verrucous growth
measuring 1 × 0.7 cm overlying the
plaque [Figure 1a], which she reported
having appeared a few months ago.
A meticulous inspection of the growth
revealeda coalescence of multiple conical
warty projections. The dermoscopic
evaluation revealed nger‑like
projections, thrombosed vessels, and
yellowish structureless areas [Figure 1b].

papillomatosis, hyperkeratosis, and large
lobules of immature sebaceous glands
in the dermis [Supplementary Figure 1].
A diagnosis of naevus sebaceus (NS),
along with the presence of verruca
vulgaris, was proered. The occurrence
of new‑onset verrucous growths overlying
NS presents a diagnostic dilemma, with
benign growths such as verruca and
syringocystadenoma papilliferum (SCAP)
overlying NS.[1] Dermoscopy guides the
dierentiation between SCAP, cutaneous
horn, and verruca vulgaris. Papillomatous
growth, nger‑like structures, dotted
vessels, and yellowish structureless
areas point toward verruca.[2] Erosions,
polymorphic, and hairpin vessels indicate
the occurrence of SCAP.[3] Cutaneous
horn is characterized dermoscopically
by horizontal structural contours, a dull
red background, and follicular scales,[4]

in our case was based on her clinical presentation of a
non‑eroded, verrucous growth, and the dermoscopic
assessment revealed nger‑like projections and dotted
vessels.
