REYES, MT et al. Solitary mastocytoma: a propos of a case. Rev. argent. dermatol. [online]. 2013, vol.94, n.2. ISSN 1851-300X.

Solitary mastocytoma is the second most frequent disease within mastocytosis. It is characterized by a hyperplasia of the mastocitos tissue that affects only the skin. It is usually congenital though it can also appear in the first weeks of life, with unknown etiology; it has a good prognosis due to its spontaneous resolution in the adolescence. This paper presents case of a patient who, from birth, has had some plaque in his right forearm, with negative and asymptomatic Darier's sign. The skin biopsy has been performed with clinical data and personal history, thus confirming the diagnosis of solitary mastocytoma.
