RETROMOLAR TRIGONE SQUAMOUS CELL CARCINOMA: CASE REPORT

Abstract

Squamous cell carcinoma accounts for more than 90 % of malignant tumours of the oral cavity. It is most likely to appear in males over the age of 40. Smoking, alcohol consumption, chronic irritation and poor oral hygiene are identified as the most common etiological factors. The first clinical sign is asymptomatic ulceration. The most frequent involved sites are tongue, followed by mouth floor, alveolar ridge, and hard palate. Retromolar trigone region involvement is rare. Retromolar trigoneis a region that triangulary shaped of which base of the trigone extends from distal surface of the last molar tooth to the posterior mandibular alveolus and the apex of trigone is maxillary alveoler tuberosity. The lateral border of this triangle is coronoid process, medial border is limited to the anterior tonsillar pillars. The carcinomas of this region are invaded to the mandibular periosteum because in retromolar trigone, mucous membrane is firmly connected to the ramus of mandible. In this case report; the clinical, radiological and pathological findings are presented of a 75-yearsold male patient that is diagnosed with squamous cell carcinoma which is widely involved and started with painless swelling in the retromolar trigone

RETROMOLAR TRİGON SKUAMÖZ HÜCRELİ KARSİNOM:

Abstract

Skuamöz hücreli karsinom oral kavitede görülen malign tümörlerin % 90’ından fazlasını oluşturmaktadır. Sıklıkla 40 yaş üzerindeki erkeklerde görülür. Tütün, alkol kullanımı, kötü ağız hijyeni ve kronik irritasyon en önemli etyolojik faktörlerdendir. Klinik olarak ilk bulgu ağrısız ülserlerin varlığıdır. En sık tutulum bölgeleri; dil, ağız tabanı, alveolar ark ve sert damaktır. Retromolar trigon bölgesinde ise tutulum nadirdir. Retromolar trigon; üçgen şeklinde, tabanı son molar dişin distal yüzeyinden posterior mandibular alveolusa kadar uzanan ve apeksi tüber maksillada olan bir bölgedir. Lateral sınırı koronoid proses, medial sınırı ise anterior tonsiller plikalardır. Mukoza ile mandibular ramus arasındaki sıkı bağlantıdan dolayı bu bölge karsinomları periosta sıklıkla invaze olur.

Bu olgu sunumunda; retromolar trigon bölgesinde ağrısız şişlik şeklinde başlayan, çok geniş tutulum gösteren skuamöz hücreli karsinom tanısı konulan 75 yaşındaki erkek hastanın klinik, radyolojik ve patolojik bulguları sunulmaktadır.
