Danazol, an inhibitor of pituitary gonadotropin, has been proposed in the treatment of systemic lupus erythematosus (SLE). We report the case of a female patient with SLE in whom a hepatocellular carcinoma was discovered after 4 years of treatment with danazol. Except for 3 days of hypochondrium pain, there were neither clinical signs of liver tumor nor biological abnormalities. An ultrasonography showed 2 tumors of the liver. At histological examination after surgery, one of the tumors was found to be a benign adenoma, while the other was a well differentiated hepatocellular carcinoma. When longterm danazol therapy is required, ultrasonography may be useful for early tumor detection.

Reported is the case of a 60-year-old female who was referred to our rheumatology center because of a high titer of antinuclear antibodies (ANAs). Initially several lupus-like features suggested a diagnosis of undifferentiated connective tissue disease (UCTD). Immunofluorescence of the patient's serum showed a nuclear dot pattern. Counterimmunoelectrophoresis for antibodies to Sm, RNP, SS-A and SS-B were negative. Immunoblotting revealed a band at 53 kD which did not correspond to known autoantigens. Several months later the patient presented to the emergency room with symptoms due to a hypertensive crisis. Check-up finally revealed a cortisone-producing tumour of the right adrenal gland. The adenoma was removed by surgery and the patient did well again.

An EIA for measuring anti-TPO autoantibodies (rhTPO-EIA) was developed using recombinant human TPO expressed in CHO cells and was compared with MC-HA generally used in laboratory routine work. rhTPO-EIA showed a satisfactory reproducibility in the intra-assay test and did not have an accidental error of lots. Almost equal number of healthy females and males were measured for their IgG binding to TPO to define a normal range of anti-TPO autoantibodies. After setting 20 IU/ml as an upper limit of normal range, sera from patient with thyroid disorders were measured for their anti-TPO autoantibodies. Chronic thyroiditis and Graves' disease were highly positive, while adenoma, thyroid cancer, SLE, and RA were low in their positivity. The positive rate of anti-TPO autoantibodies was compatible to those of previous reports in each disorder. Seventy-two sera from patients with chronic thyroiditis or Graves' disease were measured for their autoantibodies by both rhTPO-EIA and MC-HA and the results were compared between both methods. A correlation coefficient was 0.486. Following absorption with thyroglobulin, sera were measured again and as the results, the correlation coefficient increased to 0.723. Therefore, MC-HA was thought to be influenced in the presence of anti-thyroglobulin autoantibodies. Since rhTPO-EIA is excellent in quality and not affected by anti-thyroglobulin antibodies, it is useful and applicable to clinical diagnosis and observation of thyroid disorders.

TPO is a major antigen corresponding to thyroid-microsomal autoantibodies. Anti-TPO autoantibodies are very important to diagnose autoimmune thyroid disease and to estimate its clinical course. An EIA for measuring anti-TPO autoantibodies (rhTPO-EIA) was developed using recombinant human TPO expressed in CHO cells and was compared with MCHA generally used in routine laboratory work. Sera from patients with various disorders were measured for their anti-TPO autoantibodies. Chronic thyroiditis and Graves' disease were highly positive, while thyroid cancer, adenoma, SLE, and RA were low in their positivity. The positive rate of anti-TPO autoantibodies were compatible with those of previous reports of each disorder. In the comparison between rhTPO-EIA and MCHA, the correlation coefficient was 0.486. Following absorption with thyroglobulin, sera were measured again and as a result, the correlation coefficient increased to 0.723. Therefore, MCHA was thought to be influenced in the presence of anti-thyroglobulin autoantibodies. The characteristics of TPO antigen and anti-TPO autoantibodies were also summarized.

Antihypoxic drug olifen has been studied for effect in 72-hour PHA-stimulated cultures of blood lymphocytes in 15 healthy donors and 35 patients with diseases accompanied by enhanced mutagenesis in lymphocytes (rheumatoid arthritis, systemic lupus erythematosus, hypophyseal adenoma, neoplasms, chronic intoxications). Olifen has no mutagenic effect on mutagenesis in lymphocytes in a wide dose range. In diseases with intensive mutagenesis in lymphocytes olifen exhibits antimutagenic effect without lymphopoiesis.

We describe a 43-year-old woman with systemic lupus erythematosus (SLE) who had complete resolution of all SLE symptoms as a result of hypercortisolemia induced by a glucocorticoid-producing adenoma of the left adrenal gland. After an adrenalectomy, she developed an SLE exacerbation, characterized by photosensitivity, polyarthralgia, and hemolytic anemia, which required intensive steroid therapy. This is the first report of a patient with SLE entering apparent remission due to excessive adrenal secretion of glucocorticoids.

Primary hyperparathyroidism (PHP) is a metabolic illness that results from autonomous secretion of parathyroid hormone and is one of the most common causes of hypercalcemia. We present the case of a 47-year-old female with a previous diagnosis of systemic lupus erythematosus (SLE) in whom clinical (diffuse bone pain, emotional lability, jaw tumor) and laboratory features (calcium= 13.5 mg/dL, phosphate= 1.8 mg/dL, alkaline phosphatase= 3028 U/L, PTH intact= 1472 pg/dL) prompted the diagnosis of PHP secondary to parathyroid adenoma as demonstrated by the anatomopathology. After treatment with calcitonin spray 400 UI per day, IV pamidronate 90 mg/week, and subtotal parathyroidectomy, the patient status improved with normal laboratory tests. This is the second report to describe the coexistence of these two disorders in a single patient. Although the pathophysiology of the association of PHP and SLE is not known, the recognition of this association has a practical implication since the therapeutical strategy is completely different.

Approximately 1 billion people worldwide have been identified as vitamin D deficient in the 21st century, and the number is on the rise; non-classical actions of vitamin D were initially recognized around 30 y ago when receptors for vitamin D were detected in neoplastic cells lines. The aim of this review is to provide a brief overview of the non-classical actions of vitamin D. Reports describing the associations of non skeletal actions of vitamin D, especially pertaining to the immune system, inflammatory disorders, cancers and cardiovascular disease have been summarized in this paper. Reports support a role for the active form of vitamin D in mediating normal function of both the innate and adaptive immune systems. Studies also suggest a link between vitamin D deficiency and autoimmune diseases, such as rheumatoid arthritis, systemic sclerosis, systemic lupus erythematosus and type 1 diabetes. There is believed to be an inverse association between serum 25-hydroxyvitamin D concentrations and the incidence of colorectal cancer, sporadic colorectal adenoma and breast cancer. Vitamin D deficiency has been linked with various cardiovascular diseases such as hypertension, myocardial infarction, and stroke. Several epidemiological and genetic studies suggest a strong association between vitamin D and non skeletal acute and chronic disorders. However, currently, robust clinical data are still lacking to support raising intake requirements and target vitamin D plasma levels. Nonetheless, the high prevalence of vitamin D deficiency is alarming and requires implementation of clear supplementation guidelines.

The hematoxylin-eosin (H&E) stain has stood the test of time as the standard stain for histologic examination of human tissues. This simple dye combination is capable of highlighting the fine structures of cells and tissues. Most cellular organelles and extracellular matrix are eosinophilic, while the nucleus, rough endoplasmic reticulum, and ribosomes are basophilic. This review discusses the spectrum, intensity, and texture of colors observed in H&E-stained slides to illustrate their value in surgical pathology diagnosis. Changes in color of the nuclei occur in the presence of nuclear pseudoinclusions (such as papillary thyroid carcinoma) or inclusions (such as viral infection, surfactant, immunoglobulin, and biotin). The color of the cytoplasm of spindly cells can provide clues to their nature, such as basophilic (fibroblast), eosinophilic (smooth muscle and others), and amphophilic (myofibroblast). Eosinophilic globules have diagnostic value for sclerosing polycystic adenosis of salivary gland, low-grade B-cell lymphoma, solid pseudopapillary tumor of pancreas, and inclusion body fibromatosis. Eosinophilic granules are characteristic of granular cells (lysosome-rich), oncocytic cells (mitochondria-rich), and cells with secretory products (including neuroendocrine cells). Eosinophilic crystals can be diagnostic of lymphoma/plasmacytoma and crystal-storing histiocytosis. Basophilic granules or inclusions are diagnostic of acinic cell carcinoma and malakoplakia (Michaelis-Gutmann bodies). Yellow or brown inclusions are characteristic of hyalinizing trabecular adenoma of thyroid (yellow bodies), brown bowel syndrome, and malignant melanoma. Extracellular eosinophilic deposits can be produced by many conditions, but amyloid and monoclonal immunoglobulin deposition disease are important considerations. Extracellular basophilic deposits may be seen in small cell carcinoma and systemic lupus erythematosus, but they differ in that the former is blue (nuclear material) while the latter is purple (nuclear material plus immunoglobulin).

Renal neoplasia occurring as a second malignancy following childhood cancer has been most closely associated with neuroblastoma and Wilms tumor. While some cases have been associated with a genetic predisposition, nearly all are thought to result from "late effects" of therapy-related toxicity that involves chemotherapy or radiation. It is unclear if these tumors are enriched for specific molecular or morphologic characteristics. A query of our institutional nephrectomy registry of 8295 patients for renal neoplasia occurring post-treatment for childhood cancer revealed 6 patients with Wilms tumor, 4 with neuroblastoma, and 1 with acute lymphoblastic leukemia (ALL). Three additional cases of MiT family translocation renal cell carcinoma (RCC), from 2 patients, following chemotherapy for neuroblastoma and systemic lupus erythematosus and another of clear cell RCC post-ALL were included. The most common tumor type was clear cell RCC: 9/19 cases (47.4%), followed by metanephric adenoma and MiT family translocation RCC (3/19, 15.8%). There were no characteristic features to indicate a unique renal neoplasia subtype. Potential syndromic renal neoplasia occurred in 2 patients, metanephric adenomas and oncocytoma in a patient with hyperparathyroidism-jaw tumor syndrome post-treatment of Wilms tumor and a fumarate hydratase-deficient RCC in a patient post-treatment for ALL. The mean age at diagnosis of childhood neoplasia or treatment with chemotherapy or radiation was 4.7 years, and the average time to subsequent renal neoplasia was 31 years. Five (of 14) patients developed metastatic RCC, and there were 2 RCC-related deaths. These results indicate the need for extended clinical follow-up of these patients.
