title: [Internal findings in mastocytosis].
abstract: 45 patients with urticaria pigmentosa were thoroughly investigated and a systemic involvement concerning the bone marrow, the skeletal system, liver, spleen, and coagulation was often encountered. This systemization is no sign of malignancy. Benign systemic mastocytosis should be differentiated from malignant mastcell-reticulosis.
