Introduction: Chondroblastoma is a benign, epiphyseal bone tumor. It makes for approximately 1% of all bone tumors. In 1931, it was suggested to be a chondromatous variant of giant cell tumor by Codman. He reported these lesions in the region of proximal part of humerus. It is more common in second decade of life with male-to-female ratio of 2:1. It preferentially affectes the proximal part of tibia, distal part of femur, proximal humerus, and flat bones like the iliac bones.

Case report: We report case of a 15 year-old male who presented with pain over the right shoulder. Pre-operative radiograph showed a large lytic tumor arising from proximal humerus interspersed with areas of calcification which was indicative of chondroblastoma on MRI and biopsy done later.

Conclusions: This patient had chondroblastoma with minimal symptoms of pain with no other abnormality. Chondroblastomas are typically benign, but progress locally or metastatise rarely. Early diagnosis and apt primary management prevents further surgeries and recurrences.
