Where in the body are enchondromas most often found?

• A. Skull and spine
• B. Bones of the hand and feet
• C. Pelvic bones
• D. Rib cage

Answer: (B)

Enchondromas are benign cartilaginous tumors that primarily arise within the medullary cavity of the bone. They are most commonly located in the bones of the hands and feet. This is due to the high prevalence of cartilaginous tissue in the phalanges, metacarpals, and metatarsals, making these areas susceptible to the development of enchondromas.

The nature of enchondromas is that they often remain asymptomatic, and when they do cause issues, it may be linked to mechanical symptoms or pathologic fractures rather than any systemic manifestations. While enchondromas can potentially occur in other locations, such as the pelvis or rib cage, their occurrence is notably higher in the small bones of the hands and feet. This characteristic localization fits with the typical understanding of enchondroma distribution in the body.
