Resumen:
BACKGROUND: A variety of cutaneous smooth muscle neoplasms may arise in
the skin and are frequently unrecognized by clinicians. There is sparse
data relating to the dermoscopy of piloleiomyomas (PL), and nothing has
been published about the dermoscopy of angioleiomyomas (AL) and
leiomyosarcomas (LS).
OBJECTIVES: To evaluate the morphological findings of a large series of
cutaneous PL, AL and LS under dermoscopic observation, comparing these
findings among them.
METHODS: Digital dermoscopic images of 136 histopathologically confirmed
cases of cutaneous smooth muscle neoplasms (114 PL, 13 AL and 9 LS)
collected from 10 Hospitals in Spain, Austria and Italy were evaluated
for the presence of dermoscopic structures and patterns.
RESULTS: The pattern composed of a symmetric, total delicate pigment
network with the variable presence of multiple hypopigmented areas in a
painful lesion is the most common dermoscopic pattern associated with
PL. This pattern was found in 69.3% of PL and in no cases of AL and LS.
The most common and characteristic pattern associated with AL was the
one composed of symmetric pink-reddish tumour with vessels, white
structures and the absence of ulceration, which was found in 46.2% of
AL, but also in 3.5% of PL, and in 22.2% of LS. Finally, the most common
pattern associated with LS was the one composed of an asymmetric,
multilobulated tumour with linear-irregular or polymorphic-atypical
vessels and white structures, which was found in 44.4% of cases, but
also in 0.9% of PL and in 15.4% of AL.
CONCLUSION: Dermoscopy is helpful in improving the diagnostic accuracy
of PL. The dermoscopic patterns associated with AL and LS were more
variable and less specific.
