Pilomatrixoma in the Parotid Region: A Case Report

Abstract

Pilomatrixoma, which is also called calcifying epithelioma of Malherbe, tricholemmal cyst, trichomatrixoma is a benign, cutaneous, calcifying tumor originating from pluripotential precursors of hair matrix cells. It is known to occur in children but it can be seen at any age. Pilomatrixomas are most commonly found in the head and neck area. Correct preoperative diagnosis varies from 11 to 50%, so it is a diagnostic pitfall clinically and on cytology. The risk of misdiagnosis of pilomatrixoma as a malignant tumor can cause extensive surgery. In this report a patient with a mass at her parotid region, which was thought as pilomatrixoma after a magnetic resonance imaging and fine needle aspiration cytology, was presented through researching the literature. She was treated surgically.

Parotis Bölgesinde Pilomatriksoma: Vaka Sunumu

Öz

Trikomatriksoma, trikolemmal kist, Malherbe'nin kalsifiye epitelyoması olarak da adlandırılan pilomatriksoma, kıl foliküllerinin pluripotent öncülerinden köken alan benign, kutanöz, kalsifiye bir tümördür. Genellikle çocuklarda görülmekle beraber her yaşta rastlanabilinir. Pilomatriksomalar çoğunlukla baş boyun bölgesinde bulunurlar. Klinik ve sitolojik olarak tanısal zorluğu olan bir tümördür ve preoperatif olarak %11-50 oranında doğru tanı alabilmektedir. Pilomariksomanın yanlış tanı alması ise gereksiz geniş cerrahilerin yaplmasına neden olabilmektedir. Bu yazıda sağ parotis bölgesinde şişlik ile başvuran, magnetik rezonans iceleme ve ince aspirasyon biyopsisi sonucunda pilomatriksoma ön tanısı alarak, cerrahi olarak tedavi edilen olgu literatür gözden geçirilerek sunulmuştur.
