This presentation is of interest because of the occurrence of cerebellar tumors in twins that were apparently of the monozygotic or identical type. The illustrations are those of tissue from the first twin who died. It was impossible to obtain the consent of the parents for the necropsy on the second twin. However, there is little doubt that the diagnosis of the lesion in the second twin was cerebellar tumor. The exact location and histopathologic type of this tumor is, of course, not known.
The first twin died in December, 1924, at the age of 61/2 years. The second died in March, 1927, when 81/2 years of age. At the time of the death of the first twin the second had not shown any symptoms of the illness; because of this, it was impossible to obtain measurements of the twin, particularly the patterns of their palms and soles.
