Laryngeal botryoid rhabdomyosarcoma in an adult. Report of a case with electron microscopic study.
Light and electron microscopic studies of botryoid rhabdomyosarcoma of the larynx in an adult are presented. Differences in cellular composition of the central and peripheral regions of the tumor are described. The ultrastructure of the rhabdomyoblasts is discussed on the basis of criteria recently described. The findings support the hypothesis that botryoid rhabdomyosarcoma is a special subtype of rhabdomyosarcoma with low grade malignancy.
