Spontaneous osteochondroma resolution in a young female: imaging and histopathological findings

ABSTRACT

To report the first operated and histopathologically studied case of spontaneously resolving solitary osteochondroma. An 18-year-old girl presented with leg pain of 2 months' duration. She had been diagnosed to have a proximal tibial osteochondroma since the age of 9 years. Excision biopsy of the tumor remnant and its surrounding tissue was done after CT and MRI imaging. The spontaneous resolution of this case could have been due to simultaneous interruption of blood supply to the tumor and its cartilaginous cap or hyperemia around the tumor
