1/28. A case of large cell calcifying sertoli cell tumor in a child with a history of nasal myxoid tumor in infancy.A case of an 8-year-old Japanese boy with a testicular large cell calcifying sertoli cell tumor (LCCSCT) is presented. This report appears to be the first Japanese case of LCCSCT. The patient presented with left testicular swelling and gynecomastia. His family history was not contributory; however, his past history was remarkable for a benign myxoid tumor in the nasal cavity, which was removed at the age of 2 months. After removal of the testicular tumor, the gynecomastia disappeared gradually and no recurrence or metastasis developed during a 15 month follow-up period. Although the tumor was initially interpreted as a leydig cell tumor, a review of the slides after the patient's past history of nasal myxoid tumor was revealed led us to the diagnosis of LCCSCT. An accurate diagnosis of LCCSCT is crucial because this tumor is occasionally associated with carney complex, which can comprise various pathological conditions, including cardiac myxoma, that may be life-threatening. myxoma of carney complex has been described to occur in the heart, skin, oral cavity and breast in a wide age range, but there have been no reports referring to nasal myxoid tumor associated with carney complex.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/28. Soft tissue myxoma of the gingiva: report of a case and review of the literature of soft tissue myxoma in the oral region.Soft tissue myxoma of the oral cavity is extremely rare. We present a case of soft tissue myxoma arising from a mandibular anterior gingiva in a 51-year-old male patient. Histological examination showed islands of odontogenic epithelium scattered in the mucinous stroma. This lesion was supposed to have a odontogenic origin. The clinical differences between soft tissue myxoma with bone destruction and those without bone destruction are also discussed by a review of the literature.- - - - - - - - - - ranking = 0.79594172208763keywords = oral cavity, cavity (Clic here for more details about this article) |
3/28. Malignant odontogenic myxoma of the maxilla: case with cytogenetic confirmation.An odontogenic myxoma of the maxilla with an aggressive clinical course is presented. The tumour arose in a 53-year-old patient, recurred two times after extended maxillectomy and ultimately caused the patient's death by uncontrollable local disease with infiltration of the cranial cavity. Microscopically, the tumour showed histological features of a low grade malignant myxosarcoma with cellular areas, enhanced mitotic activity and nuclear pleomorphism. cytogenetic analysis revealed an unexpectedly aberrant hypertetraploid chromosome complement, that was considered as incompatible with the usual karyotypic patterns of benign tumours.- - - - - - - - - - ranking = 0.20405827791237keywords = cavity (Clic here for more details about this article) |
4/28. Aggressive angiomyxoma presenting as polyp of uterine cavity.Aggressive angiomyxoma is a distinctive, locally aggressive tumor associated with a high risk of local recurrences that lacks metastatic potential. This tumor occurs mostly in the soft tissues of the pelvis and the perineum of adult women. It may rarely occur at less common sites, such as the vagina, urinary bladder, and soft tissue of the perineum and the perianal region in men, particularly the scrotum. We report a case of aggressive angiomyxoma presenting as an endometrial uterine polyp. To the best of our knowledge, the primary location of aggressive angiomyxoma within the uterine cavity has never been described. Immunohistochemical and ultrastructural findings support the conclusion that the progenitor cell displays myofibroblastic and fibroblastic features, with a capacity for smooth muscle differentiation.- - - - - - - - - - ranking = 1.0202913895619keywords = cavity (Clic here for more details about this article) |
5/28. Left ventricular myxoma: report of a case.Although recent advances in echocardiography have made it easier to detect cardiac tumors, left ventricular myxomas are still rare and often not found until the patient presents with a history of syncopal episodes or systemic embolization. Left ventricular myxomas are usually benign and curable; however, unreliable excision of the myxoma due to poor visualization of the left ventricular cavity can result in recurrence. To prevent recurrence, it is necessary to select the most appropriate surgical approach to excise the myxoma completely. We report herein the case of a patient in whom surgical excision of a left ventricular myxoma arising from the posterior wall of the left ventricle was successfully performed.- - - - - - - - - - ranking = 0.20405827791237keywords = cavity (Clic here for more details about this article) |
6/28. Chest wall myxoma protruding into the thoracic cavity.myxoma protruding from the chest wall into the thoracic cavity is very rare. We report our experience in treating a 42-year-old man admitted for a painless mass on the anterior chest wall. magnetic resonance imaging showed a sharply defined 5 x 4 x 4 cm mass protruding from the chest wall into the thoracic cavity, which we excised surgically. Histologically, the tumor proved to be a myxoma.- - - - - - - - - - ranking = 1.2243496674742keywords = cavity (Clic here for more details about this article) |
7/28. Echocardiographic diagnosis of a mobile, pedunculated tumor in the left ventricular cavity.A mobile left ventricular tumor was detected by echocardiography. The tracing showed a cluster of echoes in the left ventricular cavity corresponding to the location of the tumor as seen in angiograms. At surgery the tumor was attached to the interventricular septum by a thin fibrous stalk.- - - - - - - - - - ranking = 1.0202913895619keywords = cavity (Clic here for more details about this article) |
8/28. myxoma of the nasal cavity and paranasal sinuses: report of a case.Myxomas are benign connective tissue tumors composed of stellate and spindle-shaped cells with benign-appearing nuclei lying in a myxoid stroma. They are usually found in the heart, soft tissues, and bones. Myxomas of the nasal cavity and paranasal sinuses are very rare. They are benign but of a locally invasive nature. Recurrent rate is high because of the difficulty to excise them completely. This article presents a case of myxoma of the nasal cavity and paranasal sinuses that extensively invaded the brain and orbits causing blindness. After three resections, also with a transbasal craniotomy in the second operation, the patient remains free from the disease.- - - - - - - - - - ranking = 1.2243496674742keywords = cavity (Clic here for more details about this article) |
9/28. Intramural cardiac myxoma in left ventricular wall: an unusual location.A 27-year-old asymptomatic woman was investigated for an abnormal finding in the cardiac contour on routine chest radiography. echocardiography revealed a heterogeneous mass in the anterolateral left ventricular wall. Excision of the tumor disclosed an absence of communication between the residual cavity and the left ventricular endocardium. Histological features of the tumor indicated an intramural myxoma.- - - - - - - - - - ranking = 0.20405827791237keywords = cavity (Clic here for more details about this article) |
10/28. Echocardiographic diagnosis of left atrial myxoma. Usefulness of suprasternal approach.Three cases of left atrial myxoma were studied by echocardiography. In one case the atrial tumour was prolapsing through the mitral orifice into the left ventricular cavity; in the other two cases it was not. The angiocardiographic and operative findings correlated well with those from echocardiography. A systematic echocardiographic study is important; the suprasternal approach is useful in the echocardiographic exploration of the left atriu, especially for nonprolapsing tumours.- - - - - - - - - - ranking = 0.20405827791237keywords = cavity (Clic here for more details about this article) |
