Overview

Patients of all age groups may develop enchondromas. Enchondromas affect men and women equally. The male to female ratio is 1:1. Periosteal chondromas commonly affect individuals of 20-30 years of age. Males are more commonly affected with periosteal chondromas than females.

Epidemiology and Demographics

Incidence

• The incidence of otesochondromas is approximately 30,000 per 100,000 of all cartilage tumors and 2,000 per 100,000 of all bone tumors.

Prevalence

• The prevalence of benign cartilage tumors is approximately 27000 per 100,000 individuals of all bone tumors and 70,000 per 100,000 of all cartilage tumors.
• The prevalence of enchondromas is approximately 12,000-24,000 per 100,000 individuals of benign bone tumors and 3000-10,000 of all bone tumors.
• The prevalence of periostal chondromas is approximately 1000 per 100,000 individuals of all chondromas and 100 per 100,000 of all bone tumors.

Age

• Patients of all age groups may develop enchondromas.
• The incidence of enchondroma peaks in the third and fourth decades of life.
• Periosteal chondromas are frequently diagnosed in the second or third decades of life.
• Patients of all age groups may develop synovial chondromas, and fifth decade is a peak incidence.

Race

• There is no racial predilection to chondroma.

Gender

• Enchondroma affects men and women equally.
• Males are more commonly affected by periosteal chondromas than females.
• Male are more commonly affected by osteochondromas than female. The male to female ratio is approximately 1.8 to 1.
• Male are more commonly affected by synovial chondroma than female.The male to female ratio is approximately 2 to 1.
