Purpose: Diffuse malignant peritoneal mesothelioma (DMPM) is a rare primary peritoneal malignancy. Its prognosis has been improved by an aggressive locoregional treatment combining extensive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Prognostic factors are currently poorly defined for this disease but are essential if treatment is to be standardized.
Methods: Twenty-eight patients with DMPM, who were considered preoperatively to be candidates for CRS and HIPEC between June 1998 and August 2010 at our institution, were selected for this study. Medical records and histopathological features were retrospectively reviewed and 24 clinical, histological, and immunohistochemical parameters were assessed for their association with overall survival by univariate and multivariate analyses.
Results: The following factors were significantly associated with overall survival by univariate analysis: predominant histological growth pattern in the epithelioid areas, nuclear grooves in the epithelioid areas, atypical mitoses, and calretinin and GLUT1 expression by immunohistochemistry in the epithelioid areas. Expression of the facilitative glucose transporter protein GLUT1 in the epithelioid areas was the only factor independently associated with overall survival by multivariate analysis.
Conclusions: GLUT1 expression appears to be an indicator of poor prognosis in DMPM. Standard histological classification of DMPM may not be adequate to select patients for aggressive locoregional treatments, such as CRS and HIPEC. Multicenter validation of the prognostic factors identified in this preliminary study is needed to refine patient selection for potential cure.

Introduction: Extraskeletal myxoid chondrosarcoma (EMC) is a rare sarcoma defined by NR4A3 gene rearrangements, typically featuring uniform cells with eosinophilic cytoplasm and mild atypia, arranged in cords or clusters within a chondromyxoid stroma. A cellular variant, characterized by increased cellular density and a solid growth pattern, has been recognized.
Methods: We encountered three cases of round cell sarcomas, diagnosed as EMC based on NR4A3 or NR4A2 rearrangements.

Composite hemangioendothelioma comprises permutations of different histological patterns few of which have been found to have specific genetic alteration and immunohistochemical expression. It comprises retiform or epithelioid hemangioendothelioma-like areas, with a variable proportion of hemangioma or low-grade angiosarcoma-like areas. It was found to express neuroendocrine markers and was seen to have a worse prognosis in recurrence or distant metastasis.

Introduction: Solitary fibrous tumor (SFT) represents an uncommon mesenchymal neoplasm affecting primarily the extremities and deep soft tissues with, overall, benign but locally aggressive biologic behavior and an underlying pathognomonic NAB2::STAT6 fusion. Intraosseous SFTs are infrequent, and involvement of the jawbones is exceedingly rare.
Case Presentation: A 54-year-old woman presented with an asymptomatic, well-demarcated, multilocular radiolucency of the left posterior mandible featuring focally irregular borders, root resorption and lingual cortex perforation.

Article Synopsis
- In a study of six EAPDC cases, histological features were similar to axial PDC, showing malignant cell characteristics, and genetic analysis revealed common loss of the SMARCB1 gene.
- Follow-up revealed significant clinical challenges, including local recurrences and metastasis within months of surgery, highlighting the aggressive nature and poor prognosis of these rare tumors.

SMARCA4-deficient undifferentiated carcinoma (SMARCA4-DUC) of the stomach is a rare gastric tumor that has been receiving increased attention in recent years. With its varied pathological presentations, accurate diagnosis can be challenging. In order to improve our understanding of this aggressive neoplasm, we have carefully documented and analyzed 4 patients with gastric SMARCA4-DUC, adding to the overall knowledge of this uncommon malignancy.
