Hypercalcemia and human nature.

Patients on hemodialysis may develop severe and symptomatic hypercalcemia if skeletal buffering is ineffective. We report a case of persistent hypercalcemia with apparent extrarenal vitamin D synthesis. Associated aluminium intoxication was suggested on desferrioxamine challenge and adynamic uremic osteodystrophy confirmed on bone biopsy. Plasma calcitriol did not suppress with corticosteroids but did with ketoconazole. No other evidence for underlying granulomatous disease was found. We discuss our approach to less usual causes of hypercalcemia, and emphasise the pitfalls associated with factitious disorders.

Membranous nephropathy resolving with treatment of bronchial carcinoid tumor.

The nephrotic syndrome and membranous nephropathy is well recognized in association with solid tumors, although less is understood of the process that links them. We report a 27-year-old man presenting with the nephrotic syndrome and stage I membranous glomerulonephritis on biopsy. A bilar mass with regional lymphadenopathy was found simultaneously, the histology of which was shown to be an infiltrative atypical bronchial carcinoid tumor. The neoplasm was successfully treated with combined chemotherapy and radiotherapy, and over this period his nephrotic-range proteinuria resolved. As has been described with other malignancies, membranous nephropathy associated with a bronchial carcinoid tumor may resolve with treatment of the underlying condition.
