[Three unusual cases of mastocytosis].

A unique opportunity arose to introduce the rare disease called mastocytosis as we had three patients with radically different clinical signs and disease progression. The authors would like to draw attention to the diagnostic problems that may emerge with this disease, as well as the diagnostic procedures are detailed. These problems, however, are dwarfed by the therapeutic difficulties faced by the clinicians. Complete remission with the present treatment opportunities may not be achieved, nevertheless, there are options to improve quality of life and to alleviate the symptoms that cause suffering to patients.
