## TL;DR

A 13-year-old girl was diagnosed with rare mid-clavicular Ewing sarcoma and treated with total claviculectomy, followed by a literature review on treatment outcomes.

## Contribution

Presents a rare case of Ewing sarcoma and provides a literature review on claviculectomy outcomes.

## Key findings

- The patient was initially misdiagnosed with a benign lipoma before being correctly diagnosed with Ewing sarcoma.
- Total claviculectomy was performed as part of the treatment plan.
- Literature review highlights limited evidence and outcomes of claviculectomy procedures.

## Abstract

Ewing sarcoma of the clavicle is an extremely rare tumor. The currently available evidence is limited to a small number of case reports. We present a case of a 13-year-old female patient referred to our tertiary care center with a progressively growing lump over the mid-clavicular, mystically diagnosed as a benign lipoma in a rural hospital. Radiological investigations and histopathological examination confirmed the diagnosis of metastatic Ewing sarcoma of the mid-clavicle. We outlined the management plan done for this patient followed by a description of the surgical technique of the total claviculectomy performed. Furthermore, we conducted a literature review on the available evidence on this topic and the functional outcomes of partial and total claviculectomy with or without reconstruction.
