A 63 year-old male, who was first diagnosed as primary macroglobulinemia (IgM-kappa type) developed non-Hodgkin's lymphoma after 10 month clinical course. He had huge, multiple intrahepatic nodular lesions and had consciousness disturbance due to marked hypercalcemia. Since the treatment with gluco-corticoid and calcitonin was not effective for the improvement of patient's general condition, calcium-free hemodialysis was performed. After 2-hour dialysis, serum-Ca level was decreased from 15. 2mg/dl to 10.0mg/dl. Histology of the aspiration biopsy specimen obtained from the liver showed malignant lymphoma, diffuse, large cell type (B cell origin). Combined chemotherapy (CHOP) was started and was quite effective not only for the regression of the primary lesions but also for the normalization of the serum-Ca level. The existence of PTH-like substance produced by the tumor cell was suspected and may be related to the hypercalcemia in this case. Finally, our results demonstrated that calcium-free hemodialysis is safe and highly effective for the management of hypercalcemia caused by malignancy.

Molecular characterization of neuroendocrine (Merkel cell) carcinoma of the skin. Review of the literature and report of three cases. Although neuroendocrine carcinoma of the skin (NECS) is comparatively a rare clinical-histological entity, numerous morphological and ultrastructural studies have been carried out since the tumor was identificated by Toker (1972). Recently immunocytochemistry has allowed a better molecular characterization (immunophenotype) of this tumor and a more exact diagnosis. The main problem for the pathologist is the differential diagnosis between NECS and skin neoplasms--both primitive and metastatic--which require a more aggressive treatment. Often the classical morphological criteria do not distinguish NECS from non-Hodgkin's lymphoma, amelanotic melanomas, cutaneous metastases of lung small cell carcinoma or of neuroblastoma. The co-expression of cytokeratins and neurofilaments constantly found in NECS, is surely the best differential criterion from non-neuroendocrine carcinomas. Furthermore, the typical paranuclear location of both the intermediate filaments in NECS is a distinctive peculiarity as opposed to lung microcytoma, where cytokeratins and neurofilaments, when present, show widespread perinuclear positivity. Chromogranin A is found only in a small percentage of tumor cells, whilst synthesis of calcitonin, somatostatin, gastrin, ACTH, is very rare. Finally, the lack of common leukocyte antigen (CLA), S-100 protein and vimentin in NECS rules out the diagnoses of lymphoma, melanoma and sarcoma respectively.

The incidence of elevated serum levels of immunoreactive calcitonin (CT) in human myeloproliferative and lymphoproliferative disorders was investigated. On the basis of twice the normal range, about 45% of patients with acute leukemia and blast crisis of chronic myelocytic leukemia (CML) showed elevated serum levels of CT. Markedly elevated levels (greater than 1,000 pg/ml) were only found in this group. Since immunoreactive CT dropped to normal or only slightly elevated levels in remission and increased again before or during relapse, serum CT levels seem to reflect the activity of the disease. However, in patients with chronic leukemia, Hodgkin's and non-Hodgkin's lymphoma, a lower incidence and only slightly elevated serum levels were found. In addition, the molecular weight of the proteohormone in serum specimen and cell extracts was investigated by gel chromatography. Besides physiological CT, different high-molecular weight forms of the hormone could be demonstrated in serum and in cell extracts. Extracts of leukemic cells revealed higher molecular forms only. It is suggested that the proteohormone is ectopically produced by leukemic cells.
