Liposarcoma of the oral cavity--case reports of the pleomorphic and the dedifferentiated variants and a review of the literature.
No full textLiposarcoma is one of the commonest soft-tissue sarcomas, but very rare in the oral cavity. We present two cases of liposarcoma of the oral cavity, together with the related clinical, histopathological and immunohistochemical findings: one affecting the cheek of a 62-year-old man and the other the gingival maxillary tuber of a 41-year-old woman. At histological examination a diagnosis of liposarcoma was made in both cases. In the first case, immunohistochemical analysis revealed intense positivity for p53, MIB-1, MDM2, and focal positivity for S100 protein and CD34, but was negative for alpha-smooth muscle actin, desmin and CD68. The second case it was intensely positive for p53, MIB-1, S-100, and focal positive for MDM2, but negative for alpha smooth muscle actin, CD34, CD68 and desmin. Histological examination and immunohistochemical profiles in the first case were consistent with pleomorphic liposarcoma, whilst that in the second case with dedifferentiated liposarcoma. Both patients were subjected to surgical treatment with wide surgical margins, without adjuvant radio- or chemotherapy. The first case was lost at follow-up one year after surgery, while the second case has not undergone relapse after seven years. We discuss differential diagnosis, examining the histopathological and immunohistochemical features that are potentially useful for distinguishing this tumor from other malignant adipose tissue tumors
Mesenchymal chondrosarcoma of the left coronoid process: report of a unique case with clinical, histopathologic, and immunohistochemical findings, and a review of the literature.
No full textMesenchymal chondrosarcoma (MCS) is a rare malignant neoplasm of bone or soft tissue origin, locally aggressive, rare in the oral cavity, of which fewer than 100 cases have been reported in the English literature. This is the first case described of this type of tumor affecting the coronoid process. The report describes a unique case of MCS in a 64-year-old woman who presented with swelling and pain at the left preauricular area just anterior to the left tragus. An orthopantomograph showed a large mass in the temporomandibular joint involving the left coronoid process and extending to the left ramus of the mandible. Biopsy and histopathologic examination revealed a biphasic pattern, composed of an undifferentiated small round-cell component surrounding a myxoid of malignant cartilage; a focally pericytic vascular pattern resembling hemangiopericytoma was observed. Immunohistochemical studies were positive for CD99, S-100, and CD45 and negative for desmin, actin, chromogranin, epithelial membrane antigen (EMA), and cytokeratin. The tumor was treated by extensive hemimandibulectomy followed by reconstruction of the area. There was no evidence of disease at the 8-year follow-up. Previously reported cases are reviewed as well
