A desmoid tumor (DT) is a benign, locally invasive soft tissue tumor associated with a high recurrence rate but with no metastatic potential.

Osteopoikilosis is a benign, asymptomatic sclerotic dysplasia of the bones. It affects both male and female and may be seen at any age. Radiographically sclerotic circular or ovoid lesions are usually symmetrically distributed in a periarticular location. Lesions can increase or decrease in size and number in serial radiographs or even disappear and do not have increased bone radiotracer uptake.
