IX Myoblastoma of the Larynx

The first reference to a myoblastoma in general was made by Weber 1 in 1854 when he reported a tumor of the tongue with micro­ scopic features suggestive of myoblastoma. N o references are made of this again until 1926 when Abriskoff 2 described a peculiar group of tumors which he believed arose from the primitive myoblasts following muscle injury. In 1934, Klemperer 3 reviewed the world literature and was able to collect 50 cases of myoblastoma of all parts of the body. In this series, four cases originated in the larynx, and again in 1934 Kleinfeld 4 reported on a single case of myoblastoma of the larynx. Since 1934, one finds in the literature reports of occasional cases, seldom numbering more than one, as reported by Geschlein, 3 Bobbio, 6 Freckner, 7 Iglauer, 8 Keohane, 9 Crane , 1 0 and Hinton and Weinberger. 1 1 The largest series of 14 laryngeal cases has been reported by McNaughton and Fraser 1 2 in 1954.
