Intramuscular Myxoma of the Tibialis Anterior Muscle
Intramuscular myxoma is a rare entity in itself, and while it has been described in several locations in the body, its presence in the tibialis anterior muscle has only been reported once in the literature. In this case report, we present, to our knowledge, the first case of an intramuscular myxoma in the tibialis anterior muscle in the English literature, which was successfully managed with wi...
متن کاملCellular/intramuscular myxoma and grade I myxofibrosarcoma are characterized by distinct genetic alterations and specific composition of their extracellular matrix
Cellular myxoma and grade I myxofibrosarcoma are mesenchymal tumours that are characterized by their abundant myxoid extracellular matrix (ECM). Despite their histological overlap, they differ clinically. Diagnosis is therefore difficult though important. We investigated their (cyto) genetics and ECM. GNAS1-activating mutations have been described in intramuscular myxoma, and lead to downstream...
متن کاملFDG PET/CT and MR imaging of intramuscular myxoma in the gluteus maximus
Intramuscular myxoma is a rare benign soft tissue tumor which may be mistaken for other benign and low-grade malignant myxoid neoplasms. We present the case of a 63-year-old woman with an asymptomatic intramuscular myxoma discovered incidentally on a whole-body F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography. PET images showed a mild FDG uptake (maximum stan...

BACKGROUND Intramuscular myxoma is a benign intramuscular neoplasm. However, sometimes it is difficult to distinguish it from soft-tissue sarcomas that underwent myxomatous degeneration. To the best of our knowledge, only 2 cases of i...
متن کاملAn Interesting Case of Intramuscular Myxoma with Scapular Bone Lysis
Introduction. Intramuscular myxoma is a rare benign primitive tumor of the mesenchyme founded at the skeletal muscle level; it presents itself like an unpainful, slow-growing mass. Myxomas with bone lysis are even more rare; only 7 cases have been reported in the English literature, but never at the shoulder level. Case Presentation. We describe an 83-year-old patient with a growing mass in the...
متن کاملIntramuscular myxoma associated with an increased carbohydrate antigen 19.9 level in a woman: a case report
INTRODUCTION Intramuscular myxoma is a rare benign soft tissue tumor. The lack of specific symptoms and widely used laboratory tests makes the diagnosis quite difficult. We present a case of an Intramuscular myxoma associated with an increased carbohydrate antigen 19.9 level. To the best of our knowledge, there have not been any reported cases of an association of Intramuscular myxoma with tumo...
