Essential thrombocythemia is a kind of myeloproliferative disorder characterized by primary elevation in the number of platelet and by multiple episodes of bleeding or thrombotic complications. Rarely, thrombocythemia itself causes coronary arterial occlusion and leads to ischemic heart disease. Fewer than twenty cases of coronary artery occlusive disease in thrombocythemia have been reported since Cheitlin et al had included thrombocythemia in their review of rare causes of myocardial infarction. We experienced a case of coronary artery disease in a 53-year-old woman with thrombocythemia, who had not coronary artery disese risk factors at all. Presence of multiple thrombus in the coronary artery was suggested in coronary angiography.

BACKGROUND AND OBJECTIVES: Various surgical approaches have been employed for the complete resection of inverted papilloma (IP) of the nose and paranasal sinus. Sacrificing the inferior turbinate (IT) and nasolacrimal duct (NLD) is often unavoidable due to the anatomy of maxillary sinus. However, the prelacrimal recess approach (PLRA) provides a wider entrance to the maxillary sinus without the ablation of NLD and IT. We present seven cases of IP successfully treated by the PLRA. SUBJECTS AND METHOD: We collected data from seven different cases involving patients who underwent resection of IP by means of the PLRA from 2016 to 2017. If the lesion could not be removed first via middle meatal antrostomy (MMA), then PLRA was attempted. The surgical specimens were all confirmed to be IP. RESULTS: Preoperative imaging studies demonstrated that the lesions of IP were located mainly in the maxillary sinus. All of the seven patients had unilateral lesions and all tumors were completely resected via PLRA. The follow-up ranged from 3 to 24 months, during which no recurrence or complications were observed in any of the seven patients. CONCLUSION: PLRA provides an adequate operation field without unfavorable scars. It allows the preservation of sinus structure and function. PLRA is feasible and can be used for the diffuse maxillary sinus IP.
