Abstract

Collision tumors in the paranasal region are extremely rare with limited literature data. To the best of our knowledge, this is the first report of associations of squamous cell carcinoma-esthesioneuroblastoma and lymphoma-hemangiopericytoma in the paranasal region. Preoperatively, radiological and clinical findings should be evaluated carefully for the diagnosis and two or more biopsy specimens should be taken from different morphological parts of the lesions. Adjuvant therapy should be planned according to two different histologies and special importance should be given to the tumor which indicates the prognosis of the patient. A multidisciplinary approach is required for the management of synchronous malignancies.

Özet

Paranazal bölgenin çarpışma tümörleri, sınırlı literatür bilgisi ile birlikte çok nadir görülmektedir. Bilgimiz dahilinde, bu paranazal bölgede skuamöz hücreli karsinom-estezionöroblastom ve lenfoma-hemanjioperistoma birlikteliğini bildiren ilk yazıdır. Tanı için ameliyat öncesi radyolojik ve klinik bulgular dikkatlice değerlendirilmeli ve lezyonun farklı morfolojik kısım- larından bir veya daha fazla biyopsi örneği alınmalıdır. Adjuvan tedavi iki değişik histoloji için planlanmalı ve hastanın prog- nozunu gösteren tümöre özel önem verilmelidir. Senkron tümörlerin yönetiminde multidisipliner yaklaşım gerekmektedir
