Zosteriform Lymphoblastoma? Presented by Dr. Paul K. Weichselbaum.
The patient is an 11-year-old boy born in Germany. About two months ago he noticed a "bumpy patch" on his left shoulder. When this patch began to extend he showed it to his parents who took him to the family doctor. He was brought for dermatologic examination on March 10, 1959.At first glance the eruption resembled herpes zoster. It extended from the midline of the upper back over the left scapular area to the deltoid and posterior axillary fold. The border was irregular and firm infiltrating bands could be palpated along the edges. The lesion was indurated and the consistency was doughy in some areas. There was a bluish cast to the eruption with erythematous and edematous zones superimposed in grouped fashion.No glands could be palpated. The blood count showed 8,300 white cells, with 50% polymorphonuclears, 47% lymphocytes, 3% eosinophils.
