Abstract

BackgroundDysplasia epiphysealis hemimelica (DEH) is a rare benign overgrowth generally affecting the epiphyses and short bones of the lower limbs. DEH in the elbow joint is extremely rare, and to date, only three cases of DEH have been reported in the radial head.Case presentationIn this study, we report a case of DEH located in the radial head of the right elbow of a 10-year-old boy, which was presented with elbow pain and limited range of motion. In clinical examination, an asymmetrical enlargement was observed over the elbow. The lesion was resected surgically, and the patient’s symptoms resolved afterward. The histologic analysis of the lesion confirmed the diagnosis of DEH.ConclusionThis report highlights the role of DEH in the differential diagnosis of elbow pathologies, particularly its differentiation from osteochondroma.

Summary

Introduction

Dysplasia epiphysealis hemimelica (DEH) is a rare benign overgrowth generally affecting the epiphyses and short bones of the lower limbs. We report a case of DEH located in the radial head of a 10-year-old boy, which was presented with pain and limited elbow range of motion. Case presentation A 10-year-old boy was referred to our center with a painful right elbow. With suspecting a diagnosis of DEH, the decision was made for resecting the lesion surgically.
