A rare case of simultaneous hypersecretion of thyroid stimulating hormone (TSH) and growth hormone (GH) in a pituitary adenoma is reported. A 59-year-old male complaining of general fatigue, dyspnea on exertion and finger tremor was admitted. Examination on admission, he revealed with hyperthyroidism and hypersecretion of TSH and thyroid hormones. Administration of TRH did not further increase serum TSH level, and administration of T3 also had no effect on TSH secretion. CT scan showed a pituitary macroadenoma 13mm in diameter. MRI demonstrated a homogenously hypointense mass with Gd-DTPA enhancement in the left side of the sella turcica. The entire chromophobic adenoma was removed by trans-sphenoidal surgery. Immunostaining of the specimen showed that the cytoplasm of the adenoma cells was positive for both TSH and GH. Double immunostaining using avidin-biotin-peroxidase complex (ABC) method and immunogold silver staining (IGSS) method, showed that the adenoma cells had been secreting both GH and TSH at the same time. After the adenomectomy, the hyperthyroidism disappeared, and all altered indicators of pituitary function returned to normal.

A 75-year-old-man who had been occupationally exposed to asbestos over several decades was admitted complaining of dry cough and mild exertional dyspnea. Chest X-ray films revealed the presence of bilateral infiltrates. An open biopsy showed the lung pathology to be desquamative interstitial pneumonitis (DIP), and detected a calcified plaque of the left parietal pleura at cost-phrenic sulcus, which on microscopic inspection demonstrated thin needle-like structures suggestive of asbestos particles. A hormonal examination showed decreased levels of tri-iodothyronine and tetraiodothyronine and an increased level of thyroid stimulating hormone. Additionally, a positive microsome test indicated autoimmune hypothyroidism. A serological study was positive for anti-nuclear antibody and direct Coombs, and showed heightened levels of IgG. The patient was placed on oral prednisolone therapy; one month later, his symptoms had subsided, and his lung function and chest x-ray findings had improved significantly. In addition, the abnormal values for autoimmune and thyroid function eventually returned to normal ranges. These findings suggest that DIP and humoral immune dysfunction were caused by asbestos exposure, and responded well to steroid treatment.
