1/5. liposarcoma involving the periodontal tissues. A case report.Liposarcomas constitute 15 to 20% of all soft tissue tumors. They are extremely rare in the head and neck and in the oral cavity. A 30-year-old patient was seen for a soft, painless mass in the right palate. Through panoramic radiography it was possible to observe a radiolucent area with sharp margins in the right upper quadrant. The lesion, after an incisional biopsy, was diagnosed as a "myxoid liposarcoma." The patient underwent a wide excision of the lesion with bone laminectomy and he is well at a 4-year follow-up. The differential diagnosis included salivary gland tumors and palatal abscess.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/5. Myxoid liposarcoma of the oral cavity with involvement of the periodontal tissues.BACKGROUND, AIMS: liposarcoma is the 2nd most frequent soft tissue sarcoma in adults, but it is extremely rare in the head and neck and, particularly, in the oral cavity. We report on a 25-year-old female who presented with a periodontal mass, extended from the right upper 3rd molar to the right upper 2nd premolar, covered by intact oral mucosa. The clinical differential diagnosis included peripheral giant cell granuloma, salivary gland neoplasms, squamous cell carcinoma of the gingiva, sarcoma and malignant lymphoma. methods: To accurately plan subsequent treatment, an excisional biopsy was performed and a myxoid liposarcoma was diagnosed. Consequently, the patient underwent wide excision of the neoplasm with maxillary en-block resection. RESULTS: The post-operative course was uneventful and the patient is alive and well 8 years after the original diagnosis. The authors stress the importance of considering soft tissue sarcomas in the diagnostic approach to patients with unusual periodontal neoplasms and to plan adequate surgical sampling of the lesion (i.e. excisional biopsy). CONCLUSIONS: This appears of pivotal importance as more limited specimens may result in inaccurate pre-operative diagnosis.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
3/5. liposarcoma of the thyroid gland mimicking retrosternal goiter.Primary liposarcoma of the thyroid gland is extremely rare with only two previous reports in the literature. We report two further cases, both patients presenting with rapid airways compression. Patient 1 had clinical, radiographic, and biopsy appearances suggesting benign goiter. Patient 2 had a long-term history of benign goiter, a previous partial thyroidectomy, and more recent biopsies showing liposarcoma. The management of such rare conditions is always challenging.- - - - - - - - - - ranking = 5keywords = gland (Clic here for more details about this article) |
4/5. Myxoid liposarcoma metastatic to the thyroid gland: a case report and literature review.We present the second reported case of a myxoid liposarcoma metastatic to the thyroid gland in a 51-year-old gentleman with previous liposarcoma of the right thigh. Myxoid liposarcoma has a relatively good prognosis but tends to recur locally. Metastases affecting the thyroid gland are a rare entity and most commonly arise from the kidney, lung or breast. Clinical presentation, patterns of recurrence and prognosis of myxoid liposarcoma and metastases to the thyroid gland are discussed.- - - - - - - - - - ranking = 7keywords = gland (Clic here for more details about this article) |
5/5. A case of liposarcoma originating in the chest wall.We encountered and reported one such rare case of liposarcoma which originated in the chest wall. A 60-year-old man came to our hospital with the chief complaint of a phyma in the right anterior chest wall. On palpation, a hard and non-mobile phyma measuring 3 x 3 cm was felt in the chest wall. Chest CT showed a phyma measuring 2.2 x 1.5 cm in the right anterior chest. The periphery of the phyma was smooth, and had a well-defined boundary with the surrounding tissues. Ultrasonic examination revealed that the tumor existed between the major and minor pectoral muscles. The inside of the tumor was nearly uniform, and showed low echo. Punctured cytological examination revealed scattered atypical cells with spindle, foamy or vacuolar sporophores on the mucoid matrix. A fat staining examination revealed lipoblasts with oil red-positive granules. Based on these findings, the patient was diagnosed as having myxoid type liposarcoma. Operation consisted of resection of the skin, subcutaneous tissues, mammary gland, part of major and minor pectoral muscles, the fourth and fifth ribs and pleura. The Reconstruction of the chest wall was performed for defects in the ribs and pleura using Marlex Mesh. Histopathological findings revealed that the tumor was myxoid type liposarcoma.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
