Geschickter, in classifying sarcomas of the nasopharynx, listed two cases as myosarcomas.1 One of these was a rhabdomyosarcoma, and he has illustrated this tumor. The second case, which is listed as being myosarcoma, has no further explanation.

Boyd feels the muscular walls of blood vessels are immune to myoma formation.4 This is difficult to understand in that myomatous tumors have been found in areas of the body which are normally devoid
