Mast cell sarcomas, part of the systemic forms of mastocytosis, are very rare tumors characterized by a destructive growth of highly atypical mast cells, with secondary spread, poor prognosis, and low survival rates. [ncbi.nlm.nih.gov]

Most mastocytosis cases have a good overall prognosis and are characterized by low mast cell burden, particularly at the early stages of the disease with limited or no systemic involvement. [consultant360.com]

In SM-AHNMD, the prognosis depends on the course of the associated haematological disorder. Agressive systemic mastocytosis and mast cell leukaemia have a poorer prognosis. [patient.info]

In general, the prognosis of childhood mastocytosis is very good. [ecnm.net]

(Etiology) The cause of Mastocytosis is usually genetic. Specifically, it is a small change (mutation) in the region of DNA of a receptor called C-KIT. [dovemed.com]

Extracutaneous mastocytoma Mast cell sarcoma (MSS) Epidemiology Uncommon Affects males more than females Bimodal age; affects pediatric age groups and adults Bone marrow and bone involvement are present in up to 90% of SM cases, followed by other organs Etiology [pathologyoutlines.com]

Etiology The etiology of mastocytosis remains unknown. Children who develop this disease usually have a self-limited disorder, whih often resolves before adulthood. [sdominko.tripod.com]

Etiology Mastocytosis probably is a hyperplastic response to an abnormal stimulus. [emedicine.medscape.com]

This observation, along with clinical disease heterogeneity has long suggested that mastocytosis is a disease of complex etiology. [thedoctorsdoctor.com]

In addition to the age of onset, adult and pediatric forms of mastocytosis differ in their clinical course and pathophysiology. [sdominko.tripod.com]

However if these lesions are causing irritation, covering a mastocytoma with a special type of bandage (hydrocolloid dressing) will prevent rubbing of the lesion, stopping the release of the mast cell’s proteins and chemicals, ultimately preventing it [aocd.org]

In most cases, only yearly checkups are necessary, and no treatment is required; preventive recommendations are warranted in individuals with systemic disease and constitutional symptoms. 6 There is no cure for more severe forms of mastocytosis, but a [consultant360.com]

Treatment was continued with only a once a day application of topical tacrolimus for a month after clinical resolution to prevent further recurrence ( Figure 4 ). [f1000research.com]

Mast cell degranulation must be avoided in extensive cases to prevent possible anaphylaxis. Chemicals that induce mast cell degranulation include alcohol, aspirin, opiates, scopolamine, amphotericin B and tubocurarine, among others. [healio.com]
