[A case of transitional cell carcinoma of renal pelvis with extremely high serum levels of CA19-9 and CEA].

We report a case of transitional cell carcinoma of the renal pelvis with extremely high serum levels of carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA). A 69-year-old woman was admitted with gross hematuria. Imaging diagnosis revealed a tumor in the left renal pelvis and multiple liver and bone metastases.

[A case of porocarcinoma arising on the penile shaft].

Background: Porocarcinoma is a rare eccrine sweat gland tumor, and a varied treatment is not yet determined for metastatic disease because of the chemo-resistant and radio-resistant nature of this tumor.

Case: This report describes a case of porocarcinoma arising on the penile shaft of 83-year-old man with extensive lymph node metastases. He was treated with emasculation and bilateral ilio-inguinal lymph node dissection.

[Establishment of two renal cancer cell lines].

Two renal cell carcinoma (RCC) cell lines, JMSU2 and JMSU3, derived from the primary sites of mixed cell type and spindle cell type RCC, respectively, have been established and maintained for 31 and 22 months. Karyotypic analysis revealed human karyotypes with modal numbers of 84 and 55, respectively. Consistent chromosomal abnormalities were 1p+, 3p-, 6q- or 8p- in the JMSU2 cells and 1p-, inv (5p + q-) or loss of sex chromosome in the JMSU3 cells.

[Role of serum E-selectin (ELAM-1) and inflammatory parameters in patients with renal cell carcinoma].

(BACKGROUND). E-selectin is an adhesion molecule expressed on IL-1 activated endothelial cells and it binds to carbohydrate ligands such as sialy Lewis A antigen (SLeA) or Lewis X antigen (SLeX) on cancer cells. This mechanism is supposed to play an important role during hematogenous metastasis.

[Primary adenocarcinoma of the tunica vaginalis testis expressing CA19-9 antigen].

A 47-year-old man presented with a 10-year history of left scrotal swelling. No solid mass detected on sonogram, dark-red colored fluid aspirated, equivocal cytology, and elevated serum CA19-9 level prompted surgical exploration. Frozen section reported no malignancy of thickening of the tunica vaginalis.
