- BACKGROUND
Decay accelerating factor (DAF/CD55), regulates the complement system by accelerating decay of the C3 convertase, has been described in several malignancies, however, the clinicopathologic significance of CD55 and its receptor CD97 has not been fully investigated. We examined the expression patterns of both CD55 and CD97 and their association with clinicopathologic parameters in colorectal cancers (CRCs).
METHODS
Expression patterns of CD55 and CD97 in the stroma and tumor cells at tumor center and invasive front were examined in 130 CRCs, and their significance was statistically evaluated.
RESULTS
CD55-high stroma was correlated with tumor border (p=0.006) and invasion depth (p=0.013). CD55-high tumor cells at tumor center and invasive front were correlated with histologic grade, and CD55-high tumor cells at invasive front with tumor, node and metastasis (TNM) stage (p<0.05).
CD97-high stroma was correlated with lymph node metastasis (p=0.016) and TNM stage (p=0.030). CD97-high tumor cells at tumor center and invasive front were correlated with tumor size and CD97-high tumor cells at tumor center with tumor border (p<0.05). Patients with CD55-high stroma showed poor overall and recurrence-free survival (p<0.05) in univariate analysis, and were independently associated with short recurrence-free survival (p=0.025) in multivariate analysis.
CONCLUSIONS
Stromal CD55 overexpression would be an indicator of adverse clinical outcome and a useful prognostic factor.

Abstract

- We report a case of Langerhans cell sarcoma presented as a solitary mass in the left supraclavicular area in a 31-year-old woman. Computed tomography revealed a relatively well-defined and lightly enhancing mass in the left supraclavicular area, measuring 5.5x4.5x3.2 cm. Excision was subsequently performed. Microscopically, the specimen consisted of an enlarged and partially effaced lymph node.
Nests of different size composed of atypical tumor cells were located in the paracortex and the medulla of the lymph node. The tumor cells exhibited abundant eosinophilic or clear cytoplasm and displayed marked nuclear atypia and increased mitotic figures. Infiltration of many eosinophils was identified in the periphery and between the tumor cells.
The tumor cells were reactive for CD1a and S100 protein.
Ultrastructually, they were found to have Birbeck granules in the cytoplasm.

Abstract
PDF
- Synovial sarcoma is a rare renal neoplasm that is not easy to diagnose unless SYT-SSX fusion transcripts are identified. We report here on a case of primary renal synovial sarcoma in a 35-year-old woman. A mass was discovered by accident in the lower part of the right kidney when ultrasonography was performed, and it was removed via radical nephrectomy. Grossly, the tumor was a homogeneously tan-brown soft mass that measured 4.5x3.2x3.0 cm, and it was encircled by a well-defined cystic space. The lesion exhibited hypercellularity of the oval or short spindle cells that were arranged in various solid sheets or intersecting fascicles. Immunohistochemically, the tumor showed diffuse positivity for vimentin, bcl-2 and CD99, and it showed focal positivity for epithelial membrane antigen.
The SYT-SSX fusion transcripts were detected by reverse transcription-polymerase chain reaction (RT-PCR). Synovial sarcoma should be considered in the differential diagnosis when a spindle cell neoplasm is encountered in the kidney.
