Introducción: Las mastocitosis cutáneas son patologías de baja frecuencia poblacional. En la mayoría de los pacientes pediátricos presentan buen pronóstico asociado a remisión espontánea de la enfermedad antes de la pubertad.

Introduction: Cutaneous mastocytosis are pathologies of low population frequency. Most pediatric patients have a good prognosis associated with spontaneous remission of the disease before puberty. There are few cases in which the disease persists into adulthood, evolving into systemic mastocytosis. Three clinical forms are differentiated: mastocytoma, polymorphic variant of maculo-papular mastocytosis (the most frequent and associated with a favorable prognosis) and monomorphic variant of maculo-papular mastocytosis (associated with a poor prognosis). A series of factors must be taken into account to establish the prognosis of cutaneous mastocytosis: clinical, histological and analytical.
Objectives: To describe data on the epidemiological and clinical characteristics, therapeutic management and evolution of pediatric cutaneous mastocytosis. Material and methods: Descriptive, observational and retrospective study, framed in the health area of the General Universitary Hospital Dr. Balmis (Alicante), of pediatric patients (0 - 15 years), diagnosed with cutaneous mastocytosis and included in databases of the hospital (period 2002-2022).
Results: 58 patients were analyzed, of which 62.1% were men and the most predominant clinical form was mastocytoma (65.5%). Likewise, the mean age at diagnosis was 10.1 months; presenting exclusively local symptoms in 96.5% of cases. Serum tryptase values at diagnosis were normal in 37.9% of patients; being above 20 μg/L in 3.5% of the cases. Topical treatment was the most prescribed (86.1%), especially corticosteroids (68.9%). Systemic treatment was used in 63.8% of the patients: type 1 antihistamines were the most used (60.3%). The skin lesions of mastocytosis resolved spontaneously, before reaching puberty, in most of the patients included in the study (86.2%). Follow-up was lost in 10.3% of cases and progressed to systemic mastocytosis in 3.5% of patients. Statistically significant differences were found between the clinical forms and the evolution of the disease (p value = 0.003).
Conclusions: In most of the patients included in the study, cutaneous mastocytosis was diagnosed at an age of less than 12 months, being more frequent in males; Mastocytoma was the most frequent histopathologically confirmed diagnostic form; and the serum tryptase values were normal, predominantly the exclusively local symptoms and the use of topical treatment. The prognosis was favorable in most cases, with spontaneous remission of the disease before puberty. Only two cases with monomorphic maculo-papular mastocytosis, systemic symptoms and elevated tryptase values evolved into systemic mastocytosis.
