What is Chondroid hamartoma?
Chondroid hamartomas are rare benign lesions of the lung comprising 8% of all lung tumors. They are usually small-sized, solitary, peripherally located, and asymptomatic lesions detected incidentally on chest X-ray or at autopsy. Rarely, they may be large in size and may clinically mimic malignancy.
Is a hamartoma benign?
A hamartoma is a local malformation made up of an abnormal mixture of cells and tissue. Although most hamartomas are benign, they cause morbidity by various mechanisms such as; infection, infarction, pressure/obstruction, hemorrhage/anemia, fracture, neoplastic transformation.
Is hamartoma malignant or benign?
A benign (not cancer) growth made up of an abnormal mixture of cells and tissues normally found in the area of the body where the growth occurs.
What is Chondroid?
Chondroid tumors are a heterogeneous group of neoplasms that all share the production of chondroid matrix. This ranges from a fetal type to mature hyaline cartilage and mirrors its imaging characteristics.
Is a hemangioma a hamartoma?
Hemangiomas, which are hamartomas composed of vascular tissue, may appear quite large at birth but are usually left untreated unless they threaten facial structures.
Are hamartomas rare?
General Discussion. Hypothalamic hamartomas (HH) are rare, tumor-like malformations that occur during fetal development and are present at birth. They are non-progressive lesions and do not expand, spread or metastasize to other locations.
Is hamartoma a tumor?

Do hamartomas cause pain?
Splenic hamartomas, while rare, trigger symptoms in more women than men. Hamartomas found on the spleen can cause pain and discomfort in the abdominal region.
How big can hamartoma get?
Pulmonary hamartomas grow slowly, and most of them are smaller than 4 cm, although they may reach 10 cm in diameter. The tumors are usually solitary, although multiple tumors in the Carney triad have been reported.
What is a benign Chondroid lesion?
Chondroid lesions are extremely common incidental findings on musculoskeletal MRI studies, since the femur and humerus are the most common location for chondroid tumors of the appendicular skeleton. Malignant degeneration of a solitary benign enchondroma is rare, but has been reported.
