Abstract
Background: Osteochondroma is a common benign bone tumour, but its spontaneous regression is a rare occurrence. The first case was reported by Hunter in 1786. And only 30 cases were found in literature to date. Spontaneous regression of osteochondroma usually occurs in paediatric age group prior to skeletal maturation without any sequelae. The exact pathophysiology of its spontaneous regression is still not fully understood. We report a case of spontaneous regression of osteochondroma in a child after a 6-year period of follow up without needing any surgical intervention.International Journal of Human and Health Sciences Vol. 05 No. 03 July’21 Page: 372-374

Summary
Osteochondroma is a common benign bone tumour that typically develops during childhood with very low malignant potential. It is characterised by a bony protuberance with a cartilage cap.[1]. A pedunculated cauliflower-like osteochondroma at the medial part of the distal femur was confirmed on plain radiograph and MRI with a thin fibrous cartilage cap. She was managed conservatively with yearly follow up with radiograph for over six years, which she only complained of minimal discomfort on pressure without any significant pain
