Parameningeal rhabdomyosarcomas: case report

Abstract

Rhabdomyosarcomas are rare malignant tumors of the head and neck region. They originate from the mesenchymal cells and look like embryonal fetal muscle fibers. Rhabdomyosarcomas as morphologically in four main groups are classified embriyonal, botrioid, alveoler and pleomorphic. Head and neck area in three anatomical regions are defined in the placement of rhabdomyosarcomas. These region are orbital, parameningeal and nonparameningeal- nonorbital. Most common site is the orbital region. Other sites are the nasopharynx, middle ear, paranasal sinuses, nasal cavity, neck and larynx. Rhabdomyosarcoma generally has a poor prognosis. To improve the survey of the patients an interdisciplinary approach is necessary. Rhabdomyosarcoma is the most common soft tissue tumor in children. Majority of cases are seen first decade. It is a rare pathology, we evaluated in the literature of two parameningeal cases, which we diagnosed and operated in our clinic.
