Abstract
Elastofibroma dorsi is a rare, benign, slowly-growing connective-tissue tumor that occurs most often in the infrascapular area in elderly people. It can be detected with various imaging modalities, like CT, MRI, USG and PET. Somatostatin is an endogenous hormone known by its inhibitory and neurotransmitter effects. Ga-68 DOTATATE which is a radiolabeled somatostatin analogue may show various uptake in physiological structures and also in tumor cells. Here in this case report, we describe the receptor expression of ED and present a case whose Ga-68 DOTATATE PET-CT scan revealed bilateral infrascapular soft tissue lesions, consistent with elastofibroma dorsi. According to our knowledge, this is the second case report in the literature, showing somatostatin receptor expression in elastofibroma dorsi

Abstract
Elastofibroma dorsi sıklıkla yaşlı popülasyonda gözlenen, yavaş büyüyen bir infraskapuler bölge yerleşimli konnektif doku tümörüdür. Sıklıkla BT, MR, USG ve PET gibi çeşitli yöntemler ile saptanırlar. Somatostatin inhibitör ve nörotransmitter özellikleri ile bilinen endojen bir hormondur. Radyoaktif işaretli bir somatostatin analoğu olan Ga-68 DOTATATE pek çok doku ve tümörde değişen oranlarda tutum gösterebilir. Bu olgu sunumunda, elastofibroma dorsinin reseptör ekspresyonları anlatılmakta ve ED ile uyumlu yumuşak doku lezyonlarında Ga-68 DOTATE PET-BT ile gösterilen somatostatin reseptör ekspresyonu anlatılmaktadır. Bilgimize göre bu olgu sunumu, elastofibroma dorsideki somatostatin ekspresyonun gösterildiği literatürdeki ikinci bildiridir
