Goltz syndrome in males: A clinical report of a male patient carrying a novel variant and a review of the literature.

Here, we report a novel mosaic mutation in the gene in a male Goltz syndrome patient. We also compare the phenotypes of all reported males with a confirmed molecular diagnosis. This report serves to further clarify the phenotype of Goltz syndrome and suggests that expression in males varies.

Mastocytosis among elderly patients: A multicenter retrospective French study on 53 patients.

Mastocytosis is a heterogeneous group of diseases with a young median age at diagnosis. Usually indolent and self-limited in childhood, the disease can exhibit aggressive progression in mid-adulthood. Our objectives were to describe the characteristics of the disease when diagnosed among elderly patients, for which rare data are available.

Leukocyte telomere length in mastocytosis: correlations with depression and perceived stress.

Background: Mastocytosisis a rare disease associated with chronic symptoms related to mast cell mediator release. Patients with mastocytosis display high level of negative emotionality such as depression and stress sensibility. Brain mast cells are mainly localized in the diencephalon, which is linked to emotion regulatory systems.

Masitinib for the treatment of systemic and cutaneous mastocytosis with handicap: a phase 2a study.

Treatment options for patients suffering from indolent forms of mastocytosis remain inadequate with the hyperactivation of mast cells responsible for many of the disease's systemic manifestations. Masitinib is a potent and highly selective oral tyrosine kinase inhibitor. A combined inhibition of c-Kit and Lyn make it particularly efficient in controlling the activity of mast cells and therefore, of potential therapeutic benefit in mastocytosis.

Gastrointestinal involvement and manifestations in systemic mastocytosis.

Mastocytosis is a rare and heterogeneous disease characterized by various biological and clinical features with different prognosis and treatments. The disease is usually divided into 2 categories: a pure cutaneous and a systemic disease. Clinical features can be related to mast cells' mediators release or to pathological mast cells infiltration.

Pediatric mastocytosis is a clonal disease associated with D816V and other activating c-KIT mutations.

Adult mastocytosis is an incurable clonal disease associated with c-KIT mutations, mostly in exon 17 (D816V). In contrast, pediatric mastocytosis often spontaneously regresses and is considered a reactive disease. Previous studies on childhood mastocytosis assessed only a few patients and focused primarily on codon 816 mutations, with various results.
