Tumor List

Case Symptoms and Presentation
Osteoblastoma - Foot and Ankle
Osteochondroma

Clinically, osteochondromas present with pain due to mechanical irritation or a painless mass. A fracture can occur through the stalk of the lesion which also causes pain.

Osteochondromatosis

About 50% of affected children have identifiable lesions by age 5. Patients present with disfigurement or with pain induced by pressure on surrounding soft tissue structures. They may have short stature, limb-length discrepancies, valgus angulation of the knee and ankle, bowing of the radius with ulnar deviation of the wrist, and subluxation of the radiocapitellar joint. The ulna and fibula are more affected than the radius and the tibia. For this reason, differential growth of the paired bones it may lead to angular deformities of the forearm, wrist, leg, and ankle. Also, lesion clusters at the metaphyseal ends of the bones near the joint may lead to loss of motion, hip dysplasia, joint subluxation, nerve compression, vascular pseudo-aneurysm, cord compression, and pain.

Osteofibrous Dysplasia

The tumor presents clinically as a painless, enlarging mass.

Osteoid Osteoma

Osteoid osteoma has a distinct clinical picture of dull pain that is worse at night and disappears within 20 to 30 minutes of treatment with non-steroidal anti-inflammatory medication. Joint pain may be present with a periarticular lesion and synovitis can occur secondary to an intraarticular lesion. Local symptoms can include an increase in skin temperature, increased sweating and tenderness. Epiphyseal lesions can cause abnormal growth.

Osteoid osteoma - Foot and Ankle

Patients present with persistent pain and swelling, which is unrelated to activity. The pain may be more intense at night.

Osteoma

Osteomas are slow growing lesions that are normally completely asymptomatic. They only present if their location within the head and neck region is causing problems with breathing, vision, or hearing.

Osteomyelitis

In children Hematogenous spread of infection presents as a high fever, malaise, local pain and swelling. The clinical picture may be equivocal, and the concern about the possibility of a tumor may arise. The most common organism in patients over the age of three is coagulase positive staph aureus.In adults, the clinical presentation can be quite deceptive, since fever, elevated white count, and history of a possible source of infection are often lacking. IV drug users often have unusual organisms such as pseudomonas. Older patients may have gram negative bacteria in the spine secondary to organisms that originate as a urinary tract infection and travel through Batson's plexus. Spinal osteomyelitis may present as back pain with negative blood cultures.

Osteopoikilosis

Patients are asymptomatic, and laboratory exams are normal. Osteosarcoma has been reported to occur in affected bone. Associated conditions include: dermatofibrosis lenticularis disseminata, scleroderma, syndactyly, dwarfism, endocrine abnormalities, melorrheostosis, and cleft palate. Most patients have no other findings.

Osteosarcoma - conventional

The most common presentation is pain and a mass, which occurs near a joint. The pain may initially accompany activity, at gradually becomes more constant and may be severe at night. Patient otherwise may have few were no symptom.

Osteosarcoma - Foot and Ankle

The patient presents with insidious pain and, eventually, a mass. Initially, the pain may be intermittent and related to a minor injury or exercise activity, and thus the problem is misdiagnosed as a common sprain or strain.

The pain will become persistent with time and begin occurring at night.
