Purpose: The purpose of this study was to evaluate the soluble Apo-2L (sApo-2L) levels in the ascitic fluid and to study its potential in detecting malignant ascites and soluble CD200 (sCD200,sOX-2) levels so as to predict its clinical usage for detecting stage 4 metastatic endometrial, ovarian and breast cancer in serum samples. Methods: Ascitic fluid from 53 and blood from 25 subjects without known malignancy on admission were collected. There were 14 breast cancer (BC), 17 ovarian cancer (OC) and 19 endometrial cancer (EC) patients diagnosed later on. Blood samples for sApo-2L, sCD200, liver function tests and CEA, CA-19.9 and CA-125 were always taken and assayed in the morning. Results: Significantly low levels of sApo-2L were observed in peritoneal fluid from OC and EC patients compared to benign peritoneal fluid from control individuals. Positive sCD200, and creatinine and sCD200 and platelets in OC patients; also, sCD200 and CEA in EC patients and sCD200 and blood urea nitrogen (BUN) in healthy subjects. Conclusions: Our data indicate that low proteomics pattern of sApo-2L but not sCD200 is a good biochemical marker. Further decline in the level of sApo-2L was seen in EC compared to OC. Since higher levels of sApo-2L were seen with higher levels of AST, the liver might be involved in its metabolism. The positive correlation detected between sCD200 and creatinine, platelets, CEA and BUN needs to be elucidated.

Our objective was to evaluate the diagnostic yield of rapid on-site evaluation (ROSE) on the differential diagnosis of non–small cell lung carcinoma, not otherwise specified (NSCLC-NOS). Biopsied cases diagnosed as NSCLC-NOS with ROSE during 2004 through 2008 were retrieved. Diagnostic confirmation was done with immunohistochemistry (IHC) involving thyroid transcription factor-1 and p63 immunostains. For the study, 106 cases were available. The final diagnoses rendered were squamous cell carcinoma (SqCC) (n = 39) and adenocarcinoma (AC) (n = 67). Cytologic, histologic, and IHC concordance for these diagnoses occurred in 75 cases (70.8 %), of which 56 (52.8 %) were AC and 19 (17.9 %) were SqCC. Cytologic, histologic, and IHC discordance was found in 31 cases (29.2 %). Of these 31 cases, 11 NSCLC-NOS diagnoses histologically corresponded to 1 SqCC plus 4 ACs, and 4 favor SqCC plus 2 ACs; the former 5 NSCLC-NOS cases classified correctly through cytology, as well as IHC. However, IHC was not available for the latter 6 NSCLC-NOS cases that were also classified correctly through cytology. In addition, only 3 NSCLC-NOS diagnoses cytologically corresponded to 3 favor SqCC histologically, in which IHC was not available, and for 2 cases that both corresponded to favor SqCC and favor AC histologically and cytologically. In the other 15 cases, histology labeled 4 cases NSCLC-NOS and misclassified 2 cases; cytology labeled 1 case NSCLC-NOS and misclassified 13 cases. ROSE has high diagnostic yield over subclassification of NSCLC-NOS. We recommend allocating a cytotechnologist for specimen adequacy and a cytopathologist for cytologic diagnosis. © 2014, Arányi Lajos Foundation.

Breast Reduction (BR) is a common procedure around the world. Patients are screened for incidental carcinoma preoperatively by mammography or ultrasonography and BR specimens are sent for pathologic examination postoperatively. Since the incidence of incidental carcinoma is very low, no consensus exist regarding efficiency of pathologic examination. To assess the value of pathologic examination, we examined mammographically and ultrasonographically negative eighty BR specimens from 40 women. Twenty seven women had pathological lesions in their specimens (67,5%). This indicates that, even mammographically and ultrasonographically innocuous, BR specimens may reveal important pathological diagnosis that alters patient management. © 2013, CIC Edizioni Internazionali, Roma.

Extramedullary hematopoiesis (EMH) is a phenomenon in which hematopoietic cells are found in sites other than the bone marrow. It is usually observed in the liver and spleen but may occasionally be found within solid tumors. The current case report presents a 69-year-old female patient who presented with a renal cyst. Histopathological examination following surgical removal of the cyst revealed a lining of oncocytic- and chromophobe-type cells with capsular invasion and a mass forming EMH with evident bone trabeculae within the cyst wall. Circulating hematopoietic stem cells in the blood and their colonization within tissues is discussed in the present case report, emphasizing certain types of renal cell carcinoma.
