Figure 1. A 79-year-old gentleman was admitted to the hospital following a reaction to a CT scan dye. He was having the CT scan because of a 2-week history of profuse diarrhoea and had become mildly anaemic and mildly neutropenic. (Hb-102 g/L, WBC-3.2*10^9/L, Neu 1.6*10^9/L, Platelet 292*10^9/L). Normal renal and liver function. S.Tryptase was greater than 200.0 ug/L (<15.0). The CT-Scan revealed multiple osteolytic lesions in the spinal region. A bone scan revealed diffuse with irregular uptake in the axial bones, humerus, and the femur along the long shaft, upper tibial shafts, and forearm bones. The scanner view of the trephine demonstrates areas of normal haemopoietic tissue along with areas of mast cells with marked fibrosis. The bony trabeculae are increased in volume with evidence of increased bony turnover.
