Multiple Myoblastomas in Children

Myoblastoma or granular cell myoblastoma is an unusual condition of the skin and internal organs. While its characteristic histopathology is agreed upon, its histogenesis is in dispute. It was first established as an entity by Abrikossoff in 1926 on the basis of five cases.¹Subsequently in 1931 Abrikossoff added seven more cases.²In 1952 Wen-Hsiang Ma³collected 287 cases from the literature. Of these, the ages of the patients were given in 68 cases. Whereas 62 were adults, only 4 were in the first decade of life and 2 in the second decade. These reported lesions in children all were solitary myoblastomas. As far as could be determined seven cases of multiple granular cell myoblastoma, all in adults, were previously recorded in the literature. Klemperer⁴reported a 23-year-old Negro woman who had two isolated myoblastomas. Powell⁵described a case
