TWO RARE CASES OF NEOPLASMS OF THE NOSE AND PARANASAL SINUSES

Purpose: To present the diagnostic approach and treatment of two rare neoplasms, hemangiopericytoma and hemangioleiomyoma, treated in the ENT Dept. of Chania General Hospital. description of the cases: A female, 65 years old, with severe nasal congestion, diplopia and exophthalmos and an 82 years old male with unilateral, recurrent, moderate epistaxis were admitted in the ENT Dept. In both cases assessment included full ENT examination, laboratory tests and imaging with CT and MRI scans. For the first patient, due to extension of the lesion in the right maxillary sinus and orbit, excision biopsy with combined Caldwell-Luc and endoscopic approach was decided. Five months after initial intervention she had local recurrence and distance metastasis and underwent adjuvant chemotherapy. She is on follow up without any indication of expansion of the preexisting disease. For the second patient, specimen from the lesion in the left nostril was sent for histology and he denied any further intervention. The patient is on regular follow up without any change from the initial diagnosis. Conclusion: While clinical examination raises the suspicion, diagnosis is confirmed by histology, and extent of disease is evaluated with CT-MRI scans. Imaging should precede biopsy because of high vascularity of these tumors. Appropriate treatment is extensive removal of the lesion. keywords: hemangiopericytoma, hemangioleiomyoma, nose-paranasal sinuses.
