Epidemiology and Demographics
Non-ossifying Fibroma
Prevalence
The prevalence of fibroma is estimated to be [number] cases annually.
Incidence
Age
Non-ossifying fibromas are the most common fibrous bony lesions in children and adolescents, with a peak incidence at 10-15 years old. Non-ossifying fibromas are not seen beyond the age of 30 years, as they spontaneously heal.
Gender
Males are more commonly affected with non-ossifying fibromas than females. The male to female ratio is approximately 2 to 1.
Race
Desmoplastic Fibroma
Incidence
The incidence of fibroma is approximately .3% per 100,000 individuals worldwide.
Age
The median age at presentation is 21 years.
Gender
Desmoplastic fibromas affects men and women equally.
Ovarian Fibroma
Age
Patients of all age groups may develop ovarian fibroma. However, they are most frequently seen in middle-aged women.
Ossifying Fibroma
Age
Ossifying fibromas most frequently occur in young children (less than 10 years of age).
Chondromyxoid Fibroma
Gender
Chondromyxoid fibromas affects men and women equally.
Age
Patients of all age groups may develop chondromyxoid fibroma. However, they are most frequently seen in second and third decades. Approximately 75% of cases occur before the age of 30 years.
