Signs of systemic lesions include impaired blood coagulation, as well as gastric and duodenal ulcers. Forecast depends on localization of mastocytoma, isolation from the surrounding tissues, tumor growth rate, its size, consistence, differentiate type (determined after a biopsy and cytology). Cytology is a sensitive method of diagnosis “mastocytoma” thanks metachromatic.
