Results of laboratory testing including mast cell mediator levels, and clinical symptoms on presentation and during follow-up were analyzed. [ncbi.nlm.nih.gov]

Infectious workup was negative and shave biopsy revealed a dense, diffuse dermal infiltrate of mast cells, consistent with diffuse cutaneous bullous mastocytosis-a rare variant of cutaneous mastocytosis. [ncbi.nlm.nih.gov]

A bone scan, GI workup, and identification of the D816V c-kit mutation can also be helpful in cases where the diagnosis requires confirmation. [merckmanuals.com]

Treatment was started with oral dimethindine maleate. At the age of 18 months, oral sodium cromoglicate (SCG) was introduced. At the age of 23 months, additional treatment was started with a cutaneous emulsion containing 4% SCG. [ncbi.nlm.nih.gov]

Although our results suggest generally favourable prognosis, the review of the literature indicate that SM may occur. Therefore, more guarded prognosis should be given in DCM patients. [ncbi.nlm.nih.gov]

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]

Etiology in many patients involves an activating mutation (D816V) in the gene coding for the stem cell factor receptor c-kit, which is present on mast cells. [merckmanuals.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]

A mutation of the oncogene C-KIT D816V is found in many (but not all) cases. [ 9 ] Epidemiology [ 10 ] This is a rare and heterogeneous group of disorders, of which urticaria pigmentosa is the most common manifestation. [patient.info]

Epidemiology cutaneous mastocytosis (CM): accounts for 80% of cases of mastocytosis. It most commonly seen in children, 80% of whom are less than 6 months old. [e-immunohistochemistry.info]

Epidemiology: Mastocytosis is seen in all ethnic backgrounds. Estimated incidence is approximately 1:20,000 (4). It occurs in males and females in approximately equal ratios. [worldallergy.org]

Pathophysiology Mastocytosis is now classified with the myeloproliferative neoplasms. [5] Increased local concentrations of soluble mast cell growth factor in lesions of cutaneous mastocytosis are believed to stimulate mast cell proliferation, melanocyte [emedicine.medscape.com]

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

Pathophysiology Mast cells originate from bone marrow progenitor cells and are distributed throughout the connective tissues. They are concentrated in the skin around the peripheral nerves and adjacent to blood and lymphatic vessels. [aafp.org]

PREVENTION The following “triggers” may influence a mast cell response: drug abuse, excessive alcoho consumption, preservatives, stress, sunlight, environmental toxins, bacteria/fungi/mold, artificial colors or flavorings, heat/cold, etc. [knowcancer.com]
