We aimed at evaluating the impact of the activity of the Interdisciplinary Group for Study of Mastocytosis (GISM) of Verona on the prevalence and incidence of CMD. We examined the data of 502 adult patients diagnosed with CMD and residing in the Veneto Region, consecutively referred to GISM between 2006 and 2020. SM was diagnosed in 431 cases, while 71 patients had cutaneous mastocytosis or other CMD. Indolent SM represented the most frequent SM variant (91.0%), mainly with the characteristics of bone marrow mastocytosis (54.8%). The prevalence of SM in the adult population of the Veneto region and of the Verona province was 10.2 and 17.2\/100,000 inhabitants, respectively. The mean incidence of new SM cases in Verona was 1.09\/100,000 inhabitants\/year. Hymenoptera venom allergy was the main reason (50%) leading to the CMD diagnosis. Osteoporosis, often complicated by fragility fractures, was present in 35% of cases, even in young patients, especially males. Our data show a higher prevalence and incidence of SM than previously reported, confirming that reference centers with multidisciplinary approach are essential for the recognition and early diagnosis of CMD.<\/jats:p>","DOI":"10.3390\/cancers13246380","type":"journal-article","created":{"date-parts":[[2021,12,20]],"date-time":"2021-12-20T08:43:32Z","timestamp":1639989812000},"page":"6380","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["A Multidisciplinary Diagnostic Approach Reveals a Higher Prevalence of Indolent Systemic Mastocytosis: 15-Years\u2019 Experience of the GISM Network"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2871-9730","authenticated-orcid":false,"given":"Roberta","family":"Zanotti","sequence":"first","affiliation":[{"name":"Hematology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0716-1686","authenticated-orcid":false,"given":"Massimiliano","family":"Bonifacio","sequence":"additional","affiliation":[{"name":"Hematology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Isolan","sequence":"additional","affiliation":[{"name":"Hematology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8177-374X","authenticated-orcid":false,"given":"Ilaria","family":"Tanasi","sequence":"additional","affiliation":[{"name":"Hematology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lara","family":"Crosera","sequence":"additional","affiliation":[{"name":"Hematology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7854-3900","authenticated-orcid":false,"given":"Francesco","family":"Olivieri","sequence":"additional","affiliation":[{"name":"Allergy Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Orsolini","sequence":"additional","affiliation":[{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Rheumatology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donatella","family":"Schena","sequence":"additional","affiliation":[{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Dermatology Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrizia","family":"Bonadonna","sequence":"additional","affiliation":[{"name":"Gruppo Interdisciplinare per lo Studio Della Mastocitosi (GISM), Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"},{"name":"Allergy Unit, Department of Medicine, Azienda Ospedaliera Universitaria Integrata di Verona, 37134 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"435","DOI":"10.1111\/j.1365-2362.2007.01807.x","article-title":"Standards and Standardization in Mastocytosis: Consensus Statements on Diagnostics, Treatment Recommendations and Response Criteria","volume":"37","author":"Valent","year":"2007","journal-title":"Eur.
