AbstractAbstract PDF

Myxoid liposarcoma is a subtype of liposarcoma. This specific subtype can be identified based on its characteristic histological and cytogenetical features. The tumor has a fusion transcript of the CHOP and TLS genes, which is caused by t(12;16)(q13;p11). Most of the fusion transcripts that have been identified fall into three categories, specifically type I (exons 7-2), type II (exons 5-2), and type III (exons 8-2). A total of seven myxoid liposarcomas associated with the rare phenomenon of cartilaginous differentiation have been documented in the literature. Currently, only one of these cases has been cytogenetically analyzed, and the analysis indicated that it was a type II TLS-CHOP fusion transcript in both the typical myxoid liposarcoma and cartilaginous areas. This study presents a second report of myxoid liposarcoma with cartilaginous differentiation, and includes a cytogenetical analysis of both the myxoid and cartilaginous areas.

AbstractAbstract PDF

Primary liposarcoma of the lung is an extremely rare disease. To date, only 14 cases have been reported in the literature. We experienced a case of myxoid liposarcoma of the lung treated by surgery. The tumor was well-defined, solid, lobulated mass measuring 3.5×2 cm, involving the bronchus of the left lower lobe. Microscopically, myxoid liposarcoma was identified. The fluorescence in situ hybridization confirmed the presence of a reciprocal translocation involving DNA damage-inducible transcript 3 (DDIT3) and fused in sarcoma (FUS) genes. The patient is still alive with no recurrence or metastasis at the time of writing this report (on 20 months postoperatively). To our knowledge, this is the first cytogenetic case report of pulmonary myxoid liposarcoma.

AbstractAbstract PDF
Background

The amplification of murine double minutes (MDM2) is the primary feature of well-differentiated liposarcomas (WDLPS) and dedifferentiated liposarcomas (DDLPS), while DDIT3 rearrangement is the main one of myxoid liposarcomas (MLPS). Our aim was to evaluate the added value of MDM2 amplification and DDIT3 rearrangement in making a diagnosis and classifying lipogenic tumors.

Methods

Eighty-two cases of liposarcoma and 60 lipomas diagnosed between 1995 and 2010 were analysed for MDM2 amplification and DDIT3 rearrangement using a fluorescence in situ hybridization (FISH). The subtypes of liposarcoma were reclassified according to the molecular results, whose results were reviewed with an analysis of the relevant histologic and immunohistochemical findings.

Results

One case of lipoma (1.67%) was reclassified as a WDLPS. Of the liposarcomas, 13.4% (16/82) were reclassified after the molecular testing. Five cases of MLPS were reclassified as four cases of DDLPS and one case of myxoid lipoma. Two cases of WDLPS were reclassified as one case of spindle cell lipoma and another case of myxofibrosarcoma. Four cases of DDLPS were reclassified as two cases of leiomyosarcoma, one case of angiomyolipoma and another case of fibroinflammatory lesion. Of the six cases of pleomorphic liposarcoma, five were reclassified as DDLPS.

Conclusions

In our series, a critical revision of diagnosis was found at a rate of 3.5% (5/142) after a review of the lipomatous lesions. The uses of molecular testing by MDM2 and DDIT3 FISH were valuable to make an accurate subtyping of liposarcomas as well as to differentiate WDLPS from benign lipomatous tumor.

AbstractAbstract
Phyllodes tumors are an uncommon mammary tumors composed of benign epithelial elements and cellular, spindle cell stroma. Adipose differentiation is an uncommon stromal alteration in phyllodes tumors. Herein, a case of recurrent phyllodes tumors with liposarcomatous stroma is described. A 30-year-old female presented with a left breast mass. Histologic examination showed a phyllodes tumor with low-grade malignant potential exhibiting a few mitoses and moderate cellularity. It also contained mature adipose tissue as well as a well-differentiated liposarcomatous area. This tumor recurred 43 months later. The recurrent tumor had a higher cellular density and more mitoses than the primary tumor.

AbstractAbstract PDF
The application of fine needle aspiration (FNA) cytology to the soft tissue tumors had been neglected. In recent years, however, FNA has been used increasingly in the preoperative diagnosis of these tumors due to its usefulness and accuracy. We present 3 cases of liposarcoma, myxoid, myxoid with round cell, and pleomorphic, diagnosed by FNA cytology with histologic confirmation. Good correlation between histologic and FNA cytologic findings was found. Although the cytologic appearances of liposarcomas varied with histologic type, the main criterion was the presence of atypical multivacuolated lipoblast with characteristically scalloped nuclei.

AbstractAbstract PDF
The cytologic findings in fine needle aspiration of a case of myxoid liposarcoma of the mediastinum are described. The smear and cell block of the aspirate revealed solid clusters with background of amorphous material and scattered single tumor cells. The clusters were moderately cellular and consisted of atypical lipoblasts in varying stages of differentiation and delicate plexiform capillaries. Good correlation was found between the histologic and cytologic findings in the fine needle aspirates. The differential diagnosis between myxoid liposarcoma and other myxoid soft tissue tumors is discussed.

AbstractAbstract PDF
BACKGROUND
Ezrin has been reported to be involved in the metastasis of solid tumors in both an animal model and clinical trials. However, questions remains as to whether an ezrin expression is an independent predictor of the event-free survival of liposarcoma patients. METHODS: We analyzed 85 liposarcoma patients without metastasis at the time of presentation. We performed immunohistochemistry with anti-ezrin antibody, and we analyzed the association of an ezrin expression with the clinicopathological variables and event-free survival. RESULTS: Twenty-nine patients (34.1%) showed an ezrin expression. Among the 30 low-grade liposarcoma patients, only one patient showed ezrin positivity. The patients who had an ezrin expression were found to be at a significantly increased risk for metastasis compared with the patients who had no ezrin expression (risk ratio: 3.4, 95% confidence interval: 1.3-9.1). The 10-year metastasis-free survival rate was 26.9% for the patients with an ezrin expression and 86.7% for the patients without an ezrin expression. The ezrin expression rate increased with an advanced tumor grade and stage. CONCLUSION: An ezrin expression is an independent predictor of distant metastasis for liposarcoma. Thus, ezrin has the potential to provide additional prognostic information and to be a novel target for the development of new adjuvant therapies for treating the patients who suffer from liposarcoma.

AbstractAbstract PDF
Extrarenal retroperitoneal angiomyolipomas (AML) are extremely rare, therefore they may present a diagnostic challenge. In this paper, the authors describe a case of a huge retroperitoneal AML in a 49-year-old woman who presented with sudden abdominal pain. Computed tomography revealed the presence of a large, round, fatty mass in the retroperitoneal space, which was easily removed by surgery. The mass was well encapsulated and dark yellow on the cut surface. Microscopically, the tumor was exclusively composed of adipose tissue with frequent multivacuolated, lipoblast-like cells masquerading as well differentiated liposarcoma. In addition, there were many clear, epithelioid cells present, especially around the small blood vessels, which were reactive for HMB-45 and smooth muscle actin.

AbstractAbstract PDF
True mixed liposarcomas are extremely rare tumors. We report here on a case of mixed liposarcoma that was composed of well differentiated and pleomorphic liposarcoma. A 76-year-old man presented to us with a mass in his left upper arm. This lesion had been there for twenty years, it was recently growing rapidly and had doubled in size during the recent 2 months. The MR image showed a mass composed of a fat component and a soft tissue component with necrosis. The old fat component was revealed as well differentiated liposarcoma, and the recent growing soft tissue component was revealed as pleomorphic liposarcoma. The two components showed different immunohistochemical results for MDM2.

AbstractAbstract PDF
Primary ovarian myxoid tumor such as myxoma, myxoid liposarcoma and myxoid leiomyosarcoma is extremely rare neoplasm. We experienced a case of unusual myxoid tumor of the ovary in a 25 year-old woman. She was admitted for an incidentally found ovarian mass during antenatal check. Radiologic studies revealed a 5.5x5 cm-sized solid mass in left ovary and she was undertaken left oophorectomy. Grossly, the round ovarian mass was measuring 8x6x5 cm, and the cut surface was predominantly solid with myxoid appearance. Microscopically, the tumor was surrounded by thick collagenous capsule and had moderate cellularity and rich vascularity. The tumor cells were stellate-shaped with abundant extracellular myxoid material without atypia. We initially thought this lesion as myxoma, but the cellularity was too high as an ordinary myxoma. Myxoid liposarcoma could also be considered as the differential diagnosis, however there was no convincing lipoblast. So, we diagnosed that tumor as myxoma with uncertain malignant potential.

AbstractAbstract PDF
A dedifferentiated liposarcoma is a uncommon neoplasm characterized by the coexistence of a well-differentiated liposarcoma and non-lipogenic sarcomas. A peculiar neural-like or meningothelial-like whorling pattern of dedifferentiation has recently been reported. We report a case of dedifferentiated liposarcoma with a peculiar whorling pattern in the scrotum of a 76-year-old man. Histologically, the tumor consisted of areas of a well differentiated liposarcoma admixed with areas of a morphologically non-lipogenic sarcoma. The whorls were scattered throughout the tumor. The cells in the whorls and dedifferentiated area showed a significant nuclear PCNA and p53 protein reactivity.

AbstractAbstract PDF
We report a case of dedifferentiated liposarcoma of retroperitoneum as a recurrent form in a 41 year old male. The patient received a extirpation for retroperitoneal mass and diagnosed as myxoid liosarcoma 4 years ago. The patient experienced 3 recurrences over a period of 4 years and diagnosed as myxoid liposarcoma in the second, third recurrence also. Histologically, the mass was composed of several clearly distinct elements : well differentiated liposarcoma, myxoid liposarcoma, myxoid malignant fibrous histiocytoma, poorly differntiated sarcoma, and fibrosarcoma. Immunohistochemically, S-100 protein was expressed in the area of spindle cell sarcoma, well differentiated liposarcoma, and malignant fibrous histiocytoma but alpha-1-antichymotrypsin was only expressed in the area of myxoid malignant fibrous histiocytoma.

AbstractAbstract PDF
Liposarcoma of the male breast is rare. In English literature, nearly 90 tumors of this type can be found, but the majority of citation is female without detail descriptions of gross or microscopic features. Recently, we experienced a case with pleomorphic liposarcoma of the breast. This 62-year-old male patient presented with tumorous mass of right breast for 3 months ago. He underwent radical mastectomy under the impression of breast cancer. Received specimen was a breast and attached nodular bulging mass. The serial section reveal a relatively defined nodular mass consists of yellowish and glistened bulging tumorous lesion, measuring 5x4.5x5cm. Microscopically, there were multiple pleomorphic giant cells composed of plump esoinophilic or microvesiculated cytoplasm and bizarre nuclei with prominent nucleoli. These cells were positive staining for oil-red O. Ultrastructurally, variable sized numerous fatty vacuoles in the cytoplasm were seen.
