Abstract
Background:
The diagnosis of solitary cutaneous mastocytoma is mainly clinical, based
on lesion morphology, the presence of a positive Darier sign, and the absence of systemic involvement.
Knowledge of this condition is important so that an accurate diagnosis can be made.
Objective:
To familiarize physicians with the clinical manifestations, diagnosis, evaluation, and
management of a solitary cutaneous mastocytoma.
Methods:
A PubMed search was completed in Clinical Queries using the key term "solitary cutaneous
mastocytoma". The search strategy included meta-analyses, randomized controlled trials,
clinical trials, observational studies, and reviews. Only papers published in English language were
included. The information retrieved from the above search was used in the compilation of the present
article.
Results:
Typically, a solitary cutaneous mastocytoma presents as an indurated, erythematous, yellow-
brown or reddish-brown macule, papule, plaque or nodule, usually measuring up to 5 cm in
diameter. The lesion often has a peau d'orange appearance and a leathery or rubbery consistency. A
solitary cutaneous mastocytoma may urticate spontaneously or when stroked or rubbed (Darier
sign). Organomegaly and lymphadenopathy are characteristically absent. The majority of patients
with skin lesions that erupt within the first two years of life have spontaneous resolution of the lesions
before puberty. Treatment is mainly symptomatic. Reassurance and avoidance of triggering
factors suffice in most cases.
Conclusion:
The diagnosis is mainly clinical, based on the morphology of the lesion, the presence
of a positive Darier sign, and the absence of systemic involvement. A skin biopsy is usually not
necessary unless the diagnosis is in doubt.
