NCT07142473
Given the renewed focus on mastocytosis (recognized in Italy as a rare disease since 2018) and emerging clinical and immunogenetic knowledge, and considering the rarity of the disease and limited understanding of its progression, this observational study aims to analyze epidemiological, clinical, genetic, immunohistochemical, and laboratory characteristics of patients with mastocytosis. This will help expand knowledge about the disease and identify prognostic variables useful in developing a personalized therapeutic approach. This registry aims to collect retrospective and prospective data on patients with cutaneous and systemic mastocytosis attending the Dermatology Unit at the IRCCS Fondazione Policlinico San Matteo. This is a single-center longitudinal hospital registry including patients with cutaneous and systemic mastocytosis, collected retrospectively and prospectively to assess the clinical, serological, hematological, and molecular characteristics of patients with cutaneous and systemic mastocytosis and their correlation with specific outcomes such as disease variant (cutaneous or systemic), extent of skin involvement, and survival rate.
NCT04377828
Cutaneous mastocytosis can be isolated or associated with systemic involvement. Urticaria pigmentosa affects around 80 to 85% of adult patients with cutaneous mastocytosis. It is also frequently present in patients with mastocytosis associated with systemic involvement (80% of patients in our experience). This skin damage is one of the causes of deterioration in quality of life in patients with mastocytosis, through the loss of self-esteem, due to the appearance of lesions. However there are not treatment for urticaria pigmentosa. Skin involvement in mastocytosis is linked to the accumulation of abnormal mast cells in the dermis. However, the mast cells are not pigmented and the brown-brown color characteristic of Urticaria pigmentosa is explained by melanin pigmentation of the epidermal basal layer.
