Reticulum Cell Sarcoma

Reticulum cell sarcoma is still a distinct problem from the standpoint of pathological classification and treatment. It is generally classified as a lymphosarcoma or as a malignant lymphoma. It is usually treated by external irradiation, although for apparently accessible local disease surgery has some advocates. Despite a dramatic initial response to irradiation in many cases, ultimate prognosis is poor and the usual life expectancy is between 6 and 24 months from the time of the diagnosis.¹ The case reported here is one of a surgically inaccessible, highly malignant reticulum cell sarcoma, given only 1,000 r of external irradiation. Despite this limited treatment, the patient has for 13 years remained free of clinical recurrence, an extremely rare outcome for such a tumor. REPORT OF A CASE R.
