Botryoid rhabdomyosarcoma is an aggressive malignancy that arises from embryonal rhabdomyoblasts. Rhabdomyosarcoma (RMS) is a highly malignant neoplasm that arises from embryonal mesenchyme with the potential for differentiating into striated muscle. Sarcoma botryoides is a malignant tumor that arises from immature skeletal muscle cells (i.e., rhabdomyoblasts) lining the walls of hollow organs, including the vagina, bladder, and biliary tract. The The embryonal cell type represents more than half of all histological subtypes. Up to 10% of all childhood malignancies. Only sclerosing and pleomorphic types show significant adult incidence. The International Classification of Rhabdomyosarcoma (ICR) published in 1995 showed histology to be an important predictor of prognosis, forming the basis for risk stratification strategies adopted in subsequent Children's Oncology Group (COG) studies.

Rhabdomyosarcoma (RMS) is a rare oral malignant soft tissue tumor whose pathological features may influence the clinical behavior, treatment and prognosis of the lesion. The specimen shown here involved the nasopharynx. There is a bimodal age distribution, between 2-6 years and a second peak between 10-18 years; it is uncommon after 45 years. Although the cells show differentiation along rhabdomyoblastic lines, RMS is not limited to cells with recognizable muscle cross-striations ( 1 , 2 ). Departments of Obstetrics and Gynecology and Pathology and Pediatrics, University … 5-year failure free survival rate: 82%. Botryoid Rhabdomyosarcoma represent about 10% of all rhabdomyosarcoma and are embryonal tumors that arise under the mucosal surface of body orifices such as the vagina, bladder, nasopharynx, and biliary tract. Pleomorphic rhabdomyosarcoma is a rare variant that almost always arises in adults older than 45 years of age 1. Rhabdomyosarcoma (RMS) is a highly malignant neoplasm that arises from embryonal mesenchyme with the potential for differentiating into striated muscle. Due to the young age of affected patients, this malignancy poses a management challenge as the preservation of hormonal, sexual and reproductive function is essential. 1988 Vol. The most common histologic type is the embryonic rhabdomyosarcoma, with spindle cell or botryoid histology there is a good prognosis.

There are four major subtypes: embryonal, botryoid, alveolar and undifferentiated. In a 1997 comprehensive review from the Intergroup RMS studies of 264 patients with RMS of the orbit, conjunctiva, and eyelids, the 5-year survival was 94% for embryonal (including botryoid) and 74% for alveolar types. Rhabdomyosarcoma (RMS) belongs to the soft tissue sarcomas that have striated muscle differentiation. The histology of the resected polypoid tumor seemed compatible with a polyp; however, immunohistochemistry revealed a botryoid rhabdomyosarcoma. The head and neck region and in particular, the orbit, represent a major anatomic site for RMS. Botryoid rhabdomyosarcoma, the current name for sarcoma botryoides, now comprises a clinically and pathologically distinctive form of rhabdomyosarcomas.

It tends to occur in paediatric population, often between birth and 15 years of age 7. Rhabdomyosarcomas generally have a nonspecific infiltrative appearance, the botryoid variant is unusual in that it manifests as a polypoid or "grape-like lesion" beneath the mucosa. Nearly 80% of genitourinary tract (GU) RMS are embryonal in nature [5]. The tumor is histologically subdivided into the embryonal, alveolar, sclerosing, and pleomorphic types. Rhabdomyosarcomas are classified histomorphologically into 4 categories: alveolar, embriyonal, botryoid and pleomorphic type (Hulland, 1990).
