Tumor List

It can have an indolent clinical course without symptoms or change for years.

The tumor presents as a painless subcutaneous mass of months or years duration.

The site 90% of the time in the diaphysis of the tibia with the remaining lesions found in the fibula and long tubular bones. There is often a history of trauma associated with adamantinoma but its role in the development of this lesion remains unclear. The patient usually has swelling that may be painful. The duration of symptoms can vary from a few weeks to years.

An 9-year-old boy has right knee pain after falling during a soccer game. Radiographs are shown in Figures 13a and 13b. The injury occurred two weeks ago, and the pain has improved significantly. What is the next most appropriate step in this patient's care?

There may be a history of trauma and some have postulated a causative link between trauma and this lesion. Patients complain of pain and a slow growing mass.

Gradually increasing pain, a mass, or with a pathological fracture through the lesion. Rapid increase is lesion size has been reported in a few cases.

High grade angiosarcoma seems to have two distinct clinical presentations. First, the lesion can present as multiple lesions in a single bone, two or more adjacent bones, or perhaps all the bones of a limb. These lesions seem to have an indolent course and the prognosis remains good. The second presentation is that of single or multiple rapidly progressive lesions that metastasize to other bones or to the lung this form of the disease has a very poor prognosis. This case illustrated the later type.

Patients present with knee pain and a bone lesion. One or both sides may be symptomatic.

A palpable mass with local pain, or a slowly growing painless mass.

Clinically, patients report pain from the lesion, often of months or years duration. Pain may be associated with pathological fracture. There may be some local tenderness, but no swelling or mass is seen, and there are no systemic symptoms. There is normally no impairment of the function of the nearby joint. Spinal lesions may cause neurologic defect by pressing on the spinal cord. In some cases there is a primary underlying disorder of cholesterol metabolism or other lipid abnormalities. In these cases the lytic bone lesions are analogous to those seen in storage diseases such as Gaucher's disease. These multiple lesions are termed "xanthoma disseminatum". One reported case is of a 10 year old boy with lytic lesions in the pelvis, femur, and humerus, as well as yellow and brown papules and plaques on the face and trunk. This patient also had polyuria and polydipsia, and was found to have diabetes insipidus. (Khandpur) Radiographically, the lesion occur commonly in the ribs, pelvis, including the sacrum and ilium, or in the epiphysis or diaphysis of tubular bones. These tumors have been reported in the jaw and associated soft tissues. In another report this tumor occurred commonly around the knee.

There is a history of a mildly painful mass that seems to increase in size over many weeks or a few months. There is usually no history of trauma. There may be stiffness of a nearby joint, or other mechanical symptoms.

The tumor is a slow growing lesion that has a predeliction for the epiphysis of major long bones. Therefore, gradual onset of joint-related pain in the hip or shoulder is a typical presentation. Sometimes a pathological fracture will force the patient to see treatment for the lesion, even though there has been minor to moderate aching pain for years. The overall presentation of this lesion mimics that of a benign bone tumor.
