The activity levels of a dynorphin converting enzyme (DCE), a substance P endopeptidase (SPE) and a substance P alpha-amidating enzyme (SP-GLYE) were measured in the cerebrospinal fluid (CSF) of 90 patients with chronic low back pain, sciatica and neurological signs of rhizopathy. The DCE activity was significantly higher in men than in women. Age was related to the DCE activity independent of sex, i.e., older patients had higher enzyme activity. The activities of two substance P converting enzymes were not related to sex or age. Self-reported pain experience and affective covariates (anxiety, depression, hostility, somatization) of pain, and myelography data were not found to be related to the enzyme activity levels once adjustment had been made for sex and age. The activity levels of the enzymes measured here had no predictive value for the long-term outcome of rehabilitation and therapy at the 5-year follow-up of the patients. The sex difference in DCE activity provides further evidence in favor of the role of gender in the psychoendocrine coping with pain distress.

A 73-year-old man was admitted into the hospital because of lumbago in October, 1986. Laboratory examination on admission showed anemia, an IgA-kappa Bence Jones proteinemia. The bone marrow picture disclosed a marked involvement by the neoplastic cells, followed by leukemic conversion 2 weeks later. The leukemic cells displayed a lymphoblastoid appearance on light microscopy, but rather compatible with plasma cells on electron microscopy, showing some strands of rough endoplasmic reticulum and a prominent Golgi apparatus in the cytoplasm. The cells expressed a wide spectrum of surface markers, including those of plasma cell (PCA-1, OKT10), B cell (B1, sIg) and CALLA. Reverse hemolytic plaque assay disclosed the immunoglobulin production of monoclonal kappa chain, but a heavy chain production was recognized only in a small proportion of the cells. Under the diagnosis of multiple myeloma, he was treated with vincristine, cyclophosphamide, and prednisolone. But he died of renal failure complicating hypercalcemia after only three months of the admission in accordance with previous reports that CALLA-positive myeloma was associated with poor prognosis. This case may also represent the clinical, morphological and phenotypic diversity in multiple myeloma.

A 73-year-old man was admitted to our hospital in July 1996 because of lymphoctyosis and lumbago. Physical examination revealed hepatomegaly and anemia. Hematologic examination showed a hemoglobin concentration of 9.6 g/dl and a leukocyte count of 32,700/microliter with 74% abnormal mononuclear cells. In Wright-Giemsa stained blood films, these cells had short villi arising from 1 or 2 poles. Immunophenotyping of peripheral mononuclear cells showed moderate to strong expression of CD10, CD24, CD38, and sIg lambda, but not of CD19, CD20, or CD25. Southern blot analysis of the peripheral mononuclear cells demonstrated rearranged monoclonal bands in the C lambda. Urine immunoelectrophoresis detected a monoclonal band identifiable as lambda-type Bence Jones protein. In addition, bone X-ray studies disclosed multiple osteolytic lesions. A diagnosis of plasma cell leukemia was made, and the patient was placed on chemotherapy consisting of cyclophosphamide and prednisolone. No notable improvement in laboratory findings was seen but the patient experienced an indolent clinical course. He died of pneumonia in January 1998. The morphological and clinical findings were unusual for a case of plasma cell leukemia. This case study suggested that signs of lymphocytosis require immunophenotypic and electron microscopic studies for the differential diagnosis of plasma cell leukemia.

A 42-year-old woman was admitted to the National Cancer Center Hospital in Tokyo, Japan, because of lumbago and bilateral leg pain. Clinical examination revealed a retroperitoneal bulky tumor, a breast tumor, and lymphoblasts in bone marrow. She did not have surface lymph node swelling or systemic symptoms such as weight loss and night sweats. Lymphoblasts in bone marrow were positive for CD10 and CD19 but negative for CD20, surface immunoglobulin, and T-cell antigens. Needle biopsy of a retroperitoneal mass revealed diffuse infiltration of lymphoblastic tumor cells. Because the cells were immunoreactive for CD79a, CD10, and terminal deoxynucleotidyl transferase, the patient was diagnosed as having precursor B-lymphoblastic lymphoma (which is rare in adults) with bone marrow involvement. The patient achieved complete remission by an induction therapy for acute lymphoblastic leukemia, underwent allogeneic bone marrow transplantation, and has remained in complete remission for more than 3 years.

Cutaneous metastasis of renal cell carcinoma (RCC) is very rare. The author herein report two cases of RCC with cutaneous metastasis. Case 1: is a 75-year-old man with right lumbago. Imaging modalities including CT and MRI revealed a right renal tumor. Nephrectomy was performed. Pathological diagnosis of the renal tumor was RCC of clear cell type (Fuhrman's grade II). He denied follow-up. Nine years later, he (at the age of 84 years), a neck skin tumor emerged. Clinical diagnosis was hemangioma. Imaging modalities including CT and MRI showed several tumors in both lungs. The resection of the neck tumor was performed. The tumor was composed of clear cell type arranged in a trabecular pattern. Immunohistochemically, the tumor cells were positive for pancytokeratins, cytokeratin 18, CD10, Ki-67 (labeling=13%), but negative for CD34, factor-VIII-related antigen, CEA, EMA, melanosome (HMB45), S100 protein, p53, and HepPar-1. Metastatic RCC was diagnosed. Despite interferon therapy, he died of 6 months after the second admission. Case 2 is a 66-year-old man with gross hematuria. Imaging modalities revealed left renal tumor. A nephrectomy was performed. The pathological diagnosis was RCC of clear cell type (grade II). The tumor was invasive into the renal pelvis. He was treated by chemoradiation, but metastases of lungs, skin (thigh), and lib emerged, and died of cachexia 9 months after the admission. Necropsy of the skin tumor was performed. The skin tumor was composed of clear cells arranged in a trabecular pattern. Immunohistochemically, the tumor cells were positive for pancytokeratins (AE1/3, CAM5.2), CD10, p53, and Ki-67 (labeling=20%), but negative for CD34, factor-VIII-related antigen, CEA, melanosome (HMB45), S100 protein, and HepPar-1. A diagnosis of RCC (grade II) was diagnosed.
