Sixty-eight patients with plasmacytic neoplasia and osteosclerotic lesions were analyzed. Men predominated in this series. Mean age was 55.3 years and 26 patients were younger than 51 years at diagnosis. Early onset of disease was statistically different from multiple myeloma in general. Thirty patients had peripheral polyneuropathy and often neurological manifestations preceded other symptoms. Skeletal pain was less common, whereas hepatomegaly, splenomegaly, and lymphadenopathy were more common than in myeloma in general. Incidence of azotemia, hypercalcemia, high ESR, and anemia was lower than in myeloma. In one fourth of the patients, the number of skeletal lesions did not exceed three. Mean survival was less than 20 months from first symptom and 12 months from diagnosis. Mortality was related sometimes to polyneuropathy. Thus, in several aspects, plasmacytic neoplasia with osteosclerotic lesions is different from the classical multiple myeloma.

Sarcoidosis of bone has been observed in 29 patients for up to 43 years. It was present in the hands and/or feet in 26 patients, in the nasal bone in three and once each in the hard palate and temporal bones. There were three types of bone lesion: (a) lytic in 25 patients; rounded cortical or medullary lesions ranging in size from 1 mm to 1 cm in diameter, which on healing left a residual punched-out 'cyst'; (b) permeative in nine patients; these showed progressive cortical 'tunnelling' with remodelling of trabecular and cortical architecture; (c) destructive in three patients: rapidly progressive with pathological fractures and secondary joint surface involvement. Soft tissue swelling preceded the radiological abnormality for up to four yearts in 10 patients, accompanied it twice, followed it once and was absent on 16 (55 percent) occasions. Bone involvement was usually an incidental finding when sarcoidosis presented elsewhere. Other features included intrathoracic sarcoid (86 per cent), lupus pernio (48 per cent), skin plaques (41 per cent), ocular inflammation (48 per cent), nasal mucosal disease (24 per cent), lymphadenopathy (24 per cent), hepatomegaly (13 per cent), splenomegaly (10 per cent), and parotid enlargement (10 per cent). Pulmonary infiltration with or without lymphadenopathy was observed in three fifths and hilar adenopathy alone in one third of patients. Abnormalities in chest radiographs of patients with bone sarcoid resolved in only 20 per cent. Hypercalciuria was noted in one and hypercalcaemia in the other two patients with bone distruction.

In 82 patients, a preoperative diagnosis of primary hyperparathyroidism has been established by means of transfemoral neck vein catheterization and measurement of serum immunoreactive parathyroid hormone (iPTH). Twenty-five of these patients have had cancer in other parts of the body but with no evidence of recurrence or metastasis. One patient had carcinoma of the colon with metastases, and four were members of families with multiple endocrine adenomatosis (MEA, Types I and II). In six other hypercalcemic patients, high levels of iPTH were found also in the effluent blood from cancer sites other than the parathyroid gland, secondary to ectopic hormone production or pseudohyperparathyroidism. In addition, a high serum level of iPTH was found in the superior vena cava of a seventh patient who had carcinoma of the breast but no clinical or radiological signs of recurrence or metastasis with the exception of an enlarged liver. This iPTH finding was interpreted as being, probably, the result of parathyroid adenoma in either the neck or the mediastinum. At the time of operation, a transcervical mediastinal search was made. Four normal cervical parathyroid glands were found; three were removed. Hypercalcemia persisted after operation, and the patient died. At postmortem examination, microscopic study revealed that the disease had metastasized to lungs and hilar lymph nodes. There was massive metastasis in the liver; the liver contained a large amount of iPTH. The results of these investigations suggest that (1) venous catheterization of the neck veins and the effluent blood from extraparathyroid tumors aid in identifying and localizing iPTH production; (2) primary benign hyperparathyroidism is not uncommon in patients with cancer, and its co-existence must be recognized; (3) high serum iPTH level in the superior vena cava may be found in patients with metastatic or primary cancer of the thoracic cavity; and (4) hyperparathyroidism may be the first hint of a familial multiple endocrine syndrome.

This report deals with an unusual case of primary macroglobulinemia with hypercalcemia, chronic renal failure and systemic amyloidosis. In May 1990, a 63-year-old male was transferred to our hospital because of hypercalcemia (13.5 mg/dl) and renal failure. Clinical examinations showed anemia, macroglossia, lymph node swellings and hepatomegaly. Laboratory findings included Bence-Jones (kappa type) proteinuria (0.8 g/day), a monoclonal gammopathy of the IgM-kappa type (2.8 g/dl), a proliferation of lymphoid cells in the peripheral blood (5%) and the bone marrow (59.6%), and lymphomatous involvement of an inguinal lymph node. Serum creatinine concentration was 8.5 mg/dl. The serum levels of parathormone and vitamin D3 metabolites were normal. The roentgenogram of bones showed a compression fracture of the lumbar spine and systemic osteoporosis. The treatment included eel calcitonin, prednisolone and the CHOP regimen, followed by hemodialysis and plasmapheresis. The serum level of IgM increased to 4.6 g/dl. The patient died three months later and postmortem examination demonstrated marked systemic amyloidosis.

Sarcoidosis is being increasingly recognised in Kuwait. Twenty patients were studied over three years and the clinical, biochemical and radiological data were analysed. The clinical profile revealed thoracic involvement in all the patients as well as constitutional symptoms (50%), arthralgia (55%), arthritis (15%), chest infection (35%), tuberculosis (10%), hypercalcaemia (5%), angina (15%) and hypertension (20%). None had central nervous system manifestations. Other clinical signs were erythema nodosum (25%), hepatomegaly (30%) splenomegaly (15%) and chest signs (25%), together with salivary gland (15%), skin (15%), eye (15%), and cardiac involvement (5%). The tuberculin test was negative in all those tested. The patients were classified radiologically into stage I (55%), stage II (40%) and stage III (5%) of the disease. The clinical profile was similar to the Western pattern of the disease, but there were several differences including an older age group, more frequent constitutional symptoms, the rarity of ocular and central nervous system involvement, and initial presentation as a chest infection. Therapy with steroids alone or steroids and azathioprine was used when appropriate and the response to therapy monitored.

A 60-year-old man born in Okinawa was admitted to our hospital because of epigastralgia. Physical examination revealed general lymphadenopathy, mild hepatomegaly and skin eruption. The peripheral blood leukocyte count was 168,600/microliters, with 93% abnormal lymphocytes showing convoluted or lobulated nuclei. Anti HTLV-1 antibody was positive with titer of 1: 1280 (PA). Leukemic cells had typical ATL cells' surface markers (OKT3; 97.2%, T4; 93.3%, T8; 2.8%, OKIA1; 39.6%, IL-2R; 41.8%) and complete monoclonal HTLV-1 provirus DNA. Endoscopic examination with biopsy revealed massive involvement of ATL cells into gastric mucosa. In the course of the treatment, he had extremely massive melena, and was saved by emergency operation. Multiple ulcers were found in the resected colon. Histological examination showed the marked infiltration of the ATL cells into the mucous or submucous membrane. Thereafter, he was treated well with ALG (Anti Lymphocyte Globulin), until hypercalcemia occurred. He died of acute renal failure after hypercalcemia.

The increasing incidence of vitamin A toxicity is related to vitamin A supplementation for unfounded reasons. This article describes the common symptomatology of vitamin A toxicity, including hypercalcemia, hepatomegaly, and dermatological and neurological effects. Retinol supplements, but not carotene supplements, become toxic when free retinol circulates. Responsibilities of health professionals include questioning vitamin use when taking health histories, educating themselves with scientifically based nutritional studies and applying RDAs (recommended daily allowances) when advising clients.

The retrovirus-associated adult T-cell leukemia/lymphoma (ATL) has not been previously documented in Taiwan. Five cases identified recently by the authors are reported. Three of the patients were women, and their ages ranged from 36 to 60 years. The most important diagnostic clue was the observation of polylobated lymphoid cells in the peripheral blood. Other variably observed significant features included hypercalcemia, cutaneous eruptions, osteolytic bone lesion, hepatomegaly, and lymphadenopathy. Surface marker studies revealed that the leukemic or lymphoma cells were T-helper cells. Histopathologic examination revealed one case of pleomorphic type and three cases of medium-sized cell type. No tissue was available for study in one case. The diagnosis of ATL was confirmed by the indirect immunofluorescence test on MT-1 cell for antibodies to adult T-cell leukemia virus-associated antigen (ATLA). Three patients were dead within 6 months, and two patients had been in clinical remission for 7 and 10 months, respectively. These two latter cases were similar to the so-called smoldering type of ATL. Two descendents among nine relatives of the patients were also positive for anti-ATLA (22%). Two husbands were negative. Four of the five patients lived in the same county in northeastern coastal Taiwan, which suggested a possible clustering of ATL in that region.

Virus associated adult T-cell leukemia/lymphoma (ATLL), which includes both adult T-cell leukemia (ATL) and its non-leukemic counterpart (NLATL) was studied clinically, histologically, and immunologically. The disease usually occurred in the sixth decade in both sexes equally. The patients had a rapid clinical course with frequent leukemic changes, lymphadenopathy, hepatomegaly, and occasional skin rash. Bone marrow involvement with mild infiltration and hypercalcemia were more frequent in ATL than in NLATL. Histologically the disease was categorized as malignant lymphoma, diffuse pleomorphic type with cerebriform nuclear giant cells. The lymphoma was characterized by diffuse proliferation of tumor cells with irregular nuclear configurations, varying in size and shape, and the presence of giant cells with highly convoluted cerebriform nuclei. The giant cells seemed to be a diagnostic marker. Immunologically, the tumor cells usually possessed the surface antigens recognized by OKT 3, 4, Leu 8 and anti-Tac antibodies, indicating that they were lymphomas of helper/inducer peripheral T-cells with the receptor for interleukin 2, but they demonstrated no helper/inducer functions. The patients often died of opportunistic infections due to T-cell dysfunction caused by the disease itself and strong chemotherapy.

We report a case of an erythrophagocytic T-cell lymphoma with autoimmune hemolytic anemia, osteolytic lesions, hypercalcemia, hepatomegaly, and marrow invasion without evident lymph node, skin or peripheral blood involvement. The malignant cells were large immunoblastic cells with pleomorphic nuclei and occasional phagocytic vacuoles containing erythrocytes. Immunologic studies showed the tumor cells to have the phenotype of activated T-cells of the cytotoxic/suppressor subclass (HLA- Dr-positive, CD8 positive) with surface receptors for IgG Fc but lacking functional activity in assays of natural killer activity and antibody-dependent cytotoxicity. The tumor cells appeared to express receptors for T-cell growth factor (Tac). Cytogenetic study of marrow mononuclear cells revealed complex but non-random karyotypic abnormalities (45 XX, +11, -12, -16, 17 p+). The clinical and laboratory features indicate that erythrophagocytic T-cell lymphoma represents a true clonal malignancy of the CD8-positive subclass of T-lymphocytes.
