Chondrome

Chondrome is a benign (non-cancerous) tumor that arises from cartilage-producing cells, known as chondrocytes. These tumors are typically found in the bones, most commonly in the hands and feet. While chondromas are benign, they can sometimes cause local pain or discomfort due to their size or location, and may rarely lead to pathological fractures if the bone becomes weakened.

There are two main types of chondromas: enchondromas and periosteal chondromas. Enchondromas develop within the medullary cavity of a bone, meaning inside the bone itself. Periosteal chondromas, in contrast, grow on the outer surface of the bone, beneath the periosteum. Multiple enchondromas can occur in a condition called enchondromatosis, which may be associated with certain syndromes like Ollier disease or Maffucci syndrome.

Diagnosis of a chondrome is usually made through imaging studies such as X-rays, CT scans, or MRI. Radiographically, they often appear as well-defined, radiolucent lesions within the bone, sometimes with calcifications. Treatment is generally not required for asymptomatic chondromas. However, if a chondrome causes significant pain, interferes with function, or shows signs of potential malignancy (which is rare), surgical removal may be recommended. This can involve curettage (scraping out the tumor) or en bloc resection (surgical removal of the tumor with a margin of healthy tissue).
