Lymphoblastoma Localized on the Scalp for Thirty Years. Presented by Dr. Maximilian E. Obermayer and Dr. Ian Macdonald (by invitation).
A man, aged 56, was presented before this Society on June 13, 1944 (Arch. Dermat. & Syph. 53:64, 1946). Prior to that he had been studied by Dr. George C. Andrews, at the Vanderbilt Clinic, New York, in 1933-1934. In 1944 the presenter's diagnosis was that of lymphoblastoma of the leukemic or pseudoleukemic type, rather than true mycosis fungoides.
The patient was referred to Dr. Ian Macdonald for x-ray treatment. From 1944 to the present time the indurated plaques on his scalp responded promptly to the treatment but always recurred. The total dose administered during these 13 years was 25,200 r at 130 or 160 kv. and a half-value layer of 0.16 mm. Cu. The last series of treatment in 1957 was given at a H. V. L. of 0.23
