Sclerosing rhabdomyosarcoma presenting in the masseter muscle: a case report
UNLABELLED Sclerosing rhabdomyosarcoma (SRMS) is exceedingly rare, and may cause a great diagnostic confusion. Histologically, it is characterized by abundant extracellular hyalinized matrix mimicking primitive chondroid or osteoid tissue. So, it may be easily misdiagnosed as chondrosarcoma, osteosarcoma, angiosarcoma and so on. Herein, we report a case of SRMS occurring in the masseter muscle ...
متن کاملSclerosing rhabdomyosarcoma: a clinicopathologic and immunohistochemical study of five cases.
We report 5 cases of sclerosing rhabdomyosarcoma. The patients included 4 adults and 1 adolescent. In the 5 cases, 3 tumors occurred in the head and neck region and 2 in an extremity. Histologically, all 5 tumors were characterized by the presence of abundant extracellular hyaline matrix, mimicking osteoid or chondroid tissue. They were composed mostly of primitive small round cells that displa...
متن کاملTesticular fusocellular rhabdomyosarcoma as a metastasis of elbow sclerosing rhabdomyosarcoma: A clinicopathologic, immunohistochemical and molecular study of one case
Sclerosing rhabdomyosarcoma (SRMS) is an infrequent variant of rhabdomyosarcoma characterized by extensive intercellular hyaline fibrosis. We report the case of a 37 year-old male with a 9 x 6 cm SRMS on the right elbow. Histologically, the tumor showed an abundant extracellular hyaline matrix with extratumoral vascular emboli and microscopic foci of fusocellular embryonal rhabdomyosarcoma (FRM...
متن کاملMDM2 Amplification and PI3KCA Mutation in a Case of Sclerosing Rhabdomyosarcoma
A rare sclerosing variant of rhabdomyosarcoma characterized by prominent hyalinization and pseudovascular pattern has recently been described as a subtype biologically distinct from embryonal, alveolar, and pleomorphic forms. We present cytogenetic and molecular findings as well as experimental studies of an unusual case of sclerosing rhabdomyosarcoma. The primary lesion arose within the planta...
متن کاملRhabdomyosarcoma.
WHAT IS RHABDOMYOSARCOMA? There are two kinds of muscle cells in the body: smooth muscle cells and skeletal muscle cells. Smooth muscles control involuntary activities; skeletal muscles control voluntary activities. Rhabdomyosarcoma (RMS) is a malignant tumor ("cancer") that arises from a normal skeletal muscle cell. Not very much is known about why normal skeletal muscle cells become cancerous...
