Lipomas of the Gastrointestinal Tract: Retrospective Analysis of 19 Cases

Abstract

Abstract In this descriptive study, we aimed to present lipoma cases diagnosed in the gastrointestinal tract and to evaluate the clinicopathological features of these tumors based on literature review. In this study, patient files of 19 cases diagnosed with lipoma of the gastrointestinal tract between 2006 and 2018 were retrospectively reviewed from the archives of the Department of Pathology of Faculty of Medicine. Seventeen cases with lipoma of the gastrointestinal tract were diagnosed between 2006 and 2018. Eleven of the cases were female (%57,9), and eight (42,1%) were male. The mean age of the patients was 62,3 years (range: 36-78 years). Of the 17 cases, 14 were located in the colon, 3 in the small intestine and 1 in the stomach. The classical morphology of lipoma was seen in all cases except one case that was diagnosed with angiolipoma located in the descending colon. Generally, incidentally detected lipomas, which can be accompanied by adenocarcinomas, are tumors that can lead to gastrointestinal symptoms such as obstruction, intussusception and bleeding, and differential diagnosis of malignancies is required. All cases should be examined by appropriate radiological and endoscopic methods before operation and the most appropriate treatment option should be evaluated for each case.

Gastrointestinal Yerleşimli Lipomalar: 19 Olgunun Retrospektif Analizi

Abstract

Özet Bu tanımlayıcı çalışmada gastrointestinal sistem yerleşimli lipoma tanılı olgularının sunulması ve bu tümörlerin klinikopatolojik özelliklerinin literatür bilgileri eşliğinde değerlendirilmesini amaçlanmıştır. Çalışmamızda Tıbbi Patoloji Anabilim Dalı arşivi taranarak gastrointestinal sistem yerleşimli lipoma tanılı 19 olgu retrospektif olarak incelendi. Gastrointestinal sistem yerleşimli lipoma tanısı almış toplam 19 olgu tespit edildi. Olguların 11'i kadın (%57,9), 8'i erkekti (%42,1). Olguların yaş dağılımı 36-78 yaş arasında değişmekte olup, ortalama yaş değeri 62,3+9 yaş olarak saptandı. 19 olgunun 1'i mide, 3'ü ince barsak, 14’ü kolon ve 1'i rektum yerleşimliydi. Angiolipoma tanısı alan inen kolon yerleşimli tek olgu dışında kalan tüm olgular klasik lipoma morfolojsindeydi. Genellikle insidental olarak saptanan lipomalar, obtrüksiyon, intrususepsiyon ve kanama gibi ciddid gastrointestinal semptomlara yol açabilen, adenokarsinomalara eşlik edebilen ve malignitelerle ayırıcı tanısı yapılması gereken tümörlerdir. Tüm olgular operasyon öncesinde uygun radyolojik ve endoskopik yöntemlerle incelenmeli ve her olgu için en uygun tedavi seçeneği değerlendirilmelidir.
