An 18-year-old Malay lady was treated with high dose steroids for three and a half years for idiopathic thrombocytopaenic purpura. At 21 years, after a series of relapses, a splenectomy was carried out. In addition, two nodules at the hilum of the spleen were also removed. Histological examination of these nodules revealed features of Kaposi's sarcoma. Kaposi's sarcoma resulting from immunosuppression by corticosteroids is rare. Our patient is the first such case reported in Malaysia.
In this part of Malaysia, consent of splenectomy is virtually unobtainable, so we studied the outcome of ITP without this treatment option. Thirty-two adult patients were seen, but 7 defaulted before therapy evaluation. Of the remaining 25, 17 achieved a complete remission with prednisolone, but in only 8 was this prolonged. Twelve patients, who failed to respond to prednisolone or who required > 15 mg/day as maintenance, were offered splenectomy, but all fused. Of these 12: one has died from an intracranial haemorrhage; three others have defaulted while on no treatment with platelet counts of < 16 x 10(9)/1; one has had a baby who died from intracranial bleeding. The other seven patients have platelet counts ranging from 4 - 202 x 10(9)/1 with moderate bleeding on doses of prednisolone of 0-60 mg/day: long-term corticosteroid side-effect are evident in all but one of them. This study demonstrates that ITP patients who refuse splenectomy have a high morbidity.
