Abstract

Granüler hücreli tümör (GHT), nadir görülen mezenkimal bir neoplazmdır. Çoğunlukla baş-boyun bölgesinde özellikle de dilde yerleşim göstermekte olup nadiren rekürrens gösterir. Bu çalışmada 6 ay içerisinde nüks eden bir GHT olgusu sunduk. 53 yaşında erkek hastada sırtta yavaş büyüyen kitle GHT olarak rapor edilmiş olup tümörde pleomorfizim, mitoz, nekroz ve atipi mevcut değildi. Olgunun 6 aylık takibinde lezyon nüks etmiş ve tekrar eksize edilmiştir. Nüks lezyon eskisi ile aynı özelliklere sahipti ancak daha düzensiz sınırlı, etraf dokuya infiltratif görünümde ve yüksek Ki- 67 oranına (%10) sahipti. Belirsiz davranışlı kabul edilen olgumuzun 3 yıllık takiplerinde lokal-uzak yayılım saptanmadı. GHT genellikle benign gidişli stromal bir tümör olmakla beraber öngörülemeyen agresiv davranma potansiyeli nedeniyle tüm olgular takip altında tutulmalıdır.

Atypical granular cell tumour: case report

Abstract

Granular cell tumour (GHT) is a rare mesenchymal neoplasm. It is mostly located in the head and neck region, especially in the tongue, and it rarely recurs. In this study, we present a case of GHT recurring within 6 months. A slow-growing mass on the back in a 53-year-old male patient was reported as GHT, and the tumour did not have pleomorphism, mitosis, necrosis or atypia. During the 6-month follow-up of the case, the lesion recurred and was excised again. The recurrent lesion had the same features as before, but with a more irregular border, infiltrative appearance to surrounding tissue, and a high Ki-67 ratio (10%). No local-distant spread was detected in the 3-year follow-up of our case, which was considered to have uncertain behaviour. Although GHT is generally a benign stromal tumour, all cases should be followed up because of its unpredictable potential for aggressive behaviour.
