Malignant lymphoma of bone.
OBJECTIVE
To evaluate the diagnosis and management of patients with malignant lymphoma of bone.


METHODS
A case series review in which the minimum follow-up was 24 months and the mean follow-up was 49 months.


METHODS
All patients were managed at a tertiary care centre, although initial biopsies were often done in community centres.


METHODS
Selected for review were 15 of 18 consecutive patients who were referred to the Musculoskeletal Oncology Unit at the Mount Sinai Hospital, Toronto, between 1984 and 1989, with a bone lesion as the presenting symptom of lymphoma. The three excluded patients included two with diffuse nodal disease at presentation and one who had a second, unrelated malignant tumour.


METHODS
Staging studies (hematologic investigations, radiography, technetium bone scanning and computed tomography), surgical biopsies of the lesion, chemotherapy, radiotherapy and in some cases surgical resection of the lesion.


METHODS
The number of biopsies required for diagnosis and the incidence of complications that required operative intervention.


RESULTS
Seven of the 15 patients required more than one biopsy to establish the diagnosis. Five patients required surgical procedures for late complications that included pathologic fractures, wound infection and osteonecrosis. At 24 months' follow-up, 13 patients were disease free and 2 had died.


CONCLUSIONS
Proper biopsy and pathological evaluation are crucial in the diagnosis of lymphoma of bone. These measures will decrease the necessity for repeat biopsies. Lymphoma is best managed medically. Surgery should be reserved for biopsy and for treatment of the complications of therapy.
