Spontaneous remission of cranial diabetes insipidus due to concomitant development of ADH-producing lung cancer--an autopsied case.
The very rare occurrence of an ADH-producing small cell carcinoma of the lung in a 52 year old male patient with cranial diabetes insipidus since childhood is described. In this case diabetes insipidus disappeared concomitantly with development of lung cancer and re-appeared with shrinkage of the lung tumour by radiation therapy. Further progressive expansion of the primary and metastatic tumours induced the syndrome of inappropriate ADH secretion once again (SIADH). This deterioration in the clinical course was reflected in the plasma levels of ADH and neurophysins. The existence of vasopressin in the tumour tissue was also demonstrated by means of an immunohistochemical staining technique combined with anti-vasopressin serum.
