The case is described of a 42-year-old man with urticaria pigmentosa and documented systemic mastocytosis who had 2 episodes of loss of consciousness, headache, nasal stuffiness and faecal incontinence, following a swim in a river. Under controlled conditions the patient was subjected to immersion
Although the prognosis of maculopapular cutaneous mastocytosis (MPCM), also referred to as urticaria pigmentosa, is often benign, clinicians lack evidence to reliably predict those at risk of associated systemic manifestations. We sought to elucidate clinical markers of disease severity to provide
The diagnosis of systemic mastocytosis without urticaria pigmentosa has been made with increasing frequency since modern methods of histamine assay have been used clinically. We examined the incidence of urticaria-angioedema and mastocytosis over a recent 12-month period. Of 490 new patients we saw,
A patient with urticaria pigmentosa and systemic mastocytosis developed hypotension following indomethacin administration. He then developed further episodes not related to indomethacin. Based upon the experience of others with the management of patients with systemic mastocytosis who showed
Mastocytosis is a rare disease of mast-cell proliferation with involvement of the reticuloendothelial systems including skin, bone, gastrointestinal tract, liver, lungs, spleen, and lymph nodes. Systemic mastocytosis is characterized by a combination of symptoms that relate to the mast cells'
Systemic mastocytosis (SM), as opposed to cutaneous-only mastocytosis, implies the presence of neoplastic mast cell infiltration in extracutaneous tissue. Mast cell disease in adults is often systemic and often involves the bone marrow. Typical clinical and laboratory features of SM include
Mastocytosis has a bimodal distribution often presenting in children from birth to 2 years of age and in those over the age of 15. Pediatric mastocytosis is due to the effects of mast-cell degranulation enzymes such as histamine and tryptase causing the presentation of pruritis, flushing, vesicles,
BACKGROUND
Systemic mastocytosis (SM) is a condition typically characterized by an increased number of mast cells in the bone marrow or in skin areas known as urticaria pigmentosa. Patients may present with flushing, itching, gastrointestinal symptoms, arrhythmias, headaches and osteoporosis. Some
