An Unusual Presentation of Osteochondroma in a Sexagenarian

Abstract

Osteochondroma is the most commonly-found benign bone tumour. It is a benign, cartilaginous-capped bony projection. They are usually present on the bony surfaces of the long bones in adolescents and young adults. The risk of malignant transformation is <1% with solitary osteochondroma. We present a rare case of an osteochondroma in a patient with advanced age and an unusual location.

Superficial peroneal nerve neuroma after syndesmotic stabilisation surgery

“…While syndesmotic injuries are associated with ankle fractures (especially Weber C), they can also be limited to ligamentous injuries. The superficial peroneal nerve (SPN) is a branch of the common peroneal nerve which bifurcates into a deep peroneal branch and a superficial peroneal branch at the level of the fibular head 2 3. The sensory branch of the SPN supplies the lateral ankle and dorsum of the foot.…”

Sessile Pelvic Osteochondroma: A Rare Case That Required Abdominal Wall Reconstruction After Excision

“…1 These are more frequently encountered in the first two decades of life although clinical presentation in later age groups is also not atypical. 2 Morphologically these tumours can be either sessile or pedunculated with more predominance of the latter. Commonly found at the metaphyseal regions of long bones 1 , Osteochondromas have been described at various atypical sites such as pelvis, feet, scapula and spine [3][4][5] .…”

Osteochondroma of acromioclavicular joint

“…The pathophysiology is a peripheral chondroblast grows outward from the metaphysis, acting as an ectopic growth plate, and ceases growth at skeletal maturation. Therefore, there is an excrescence of trabecular bone capped by a thin zone of proliferating cartilage 2 3. Solitary osteochondromas can arise because of a Salter-Harris fracture in the paediatric age group, postsurgery or postradiation 3.…”

“…Therefore, there is an excrescence of trabecular bone capped by a thin zone of proliferating cartilage 2 3. Solitary osteochondromas can arise because of a Salter-Harris fracture in the paediatric age group, postsurgery or postradiation 3. Clinically, osteochondroma presents as a firm, non-tender, immovable mass arising near the end of the long bone.…”
