Abstract
Secondary thrombocytopenia was defined as a decrease in the platelet count to less than 3×104 mm3 and it was induced by Latamoxef (LMOX) administration. A 21 year-old male received a segmental resection of the mandible and a reconstructive surgery due to the calcifying odontogenic cyst. The patient was given totally 23 g of LMOX during 8 days after operation, which was intravenous administrated 2 to 3 g per day. The platelet cout was markedly decreased at 8th day after operation to 0.4-0.7×103/mm3, and petechia and ecchymosis were noticed in skin. The patient was cut off the administration of LMOX, and he was recovered platelet count 2 days after giving predonin.
