Tumor-induced hypercalcemia is a frequent complication of advanced cancers, but it has been rarely reported in patients with sarcoma. We report a 16 year-old boy presenting with polyuria, polydipsia and severe dehydration. Laboratory examination revealed severe hypercalcemia (serum calcium 23 mg/dl) which caused emaciation and was accompanied by low serum phosphorus and suppressed parathyroid hormone. Diagnostic imaging revealed a huge anterior mediastinal mass. Hypercalcemia was successfully treated with pamidronate, a bisphosphonate, and the patient underwent surgical resection. Pathological and immunohistochemical analyses confirmed a diagnosis of biphasic synovial sarcoma. To our knowledge, this is the first case of mediastinal synovial sarcoma presenting with hypercalcemia.

The present study was undertaken to investigate the toxic effects of higher doses (1,00,000 IU i.e. 2.5 mg/kg body weight (BW)) of vitamin D3, concomitantly with bacterial endotoxins (lipopolysaccharides: LPS) to study the immunomodulatory potential of vitamin D3 in IBL-80 broiler chicks. The chicks were divided into four groups [group I (NSS), group II (LPS), group III (Vit. D3 + NSS), and group IV (Vit. D3 + LPS)] containing eight chicks in each group, treated accordingly for 21 days. Birds were kept under close observation for apparent clinical signs and symptoms. Clinically, vitamin D3 treated chicks were dull, off feed, showed polydipsia, polyuria, watery faeces, rigidity of limbs, severe dehydration, weakness and significant progressive emaciation. Grossly, the bones were soft whereas most organs revealed congestion and hemorrhages in visceral organs. Histopathologically, renal tubular epithelium showed coagulative necrosis and metastatic calcification. The lung parenchyma and bronchi showed hemorrhages, congestion with diffuse heterophilic cell infiltration in inter-alveolar septa and infiltration of heterophils in alveoli along with proteinacious fluid in LPS treated chicks of treatment group, suggesting immunomodulatory action of vitamin D3. Vitamin D3 treated chicks showed strong expression of Calbindin D28k in intestine and kidney but weak expression in lung, which can be linked to nephrocalcinosis seen in kidney and from its prospective role in cellular calcium homeostasis.
