The course of lymphocytic hypophysitis.

A 27-year-old woman presented to our institution in her seventh month of pregnancy with complaints of headache and visual field disturbance. Workup revealed bitemporal hemianopia, a markedly enlarged pituitary gland on computed tomography scan, and biochemical evidence of partial hypopituitarism. At surgery, a biopsy specimen of the pituitary gland was taken revealing lymphocytic hypophysitis. The patient was treated with steroids and replacement doses of thyroid hormone. Visual fields improved postoperatively. A repeat computed tomography scan obtained 2 months after an uneventful pregnancy showed that her pituitary had regained normal size and contour. Over the next 9 months she had gradual recovery of all pituitary function. This case allowed us to follow and document the course of lymphocytic hypophysitis from its presentation as a macroadenoma with partial hypopituitarism to full recovery of both size and hormonal function of the pituitary. Lymphocytic hypophysitis should be considered in the differential diagnosis of a pituitary mass or pituitary dysfunction presenting in pregnancy. In patients with suspected lymphocytic hypophysitis and a pituitary mass, a trial of steroids may be therapeutic.

Kearns-Sayre syndrome presenting as renal tubular acidosis.

Renal tubular acidosis and tetany were the 1st manifestations of Kearns-Sayre syndrome in a 5-year-old child. Subsequently, he developed progressive external ophthalmoplegia, ptosis, retinopathy, heart block, and endocrinopathy. There was a 7.5-kb deletion of mitochondrial DNA documented in muscle, kidney, skin fibroblasts, and leukocytes, providing evidence for a multisystem mitochondrial cytopathy.

Transplantation of mouse plasmacytoma to the hamster's cheek pouch. I. Changes in tumour size and paraprotein concentration in the serum of the host.

Mouse myeloma cells (MPC-11) secreting gamma-2-b globulin were shown to proliferate into solid tumours after transplantation into the hamster cheek pouch. The implanted tumours continued to grow during the first 2 weeks; thereafter they diminished in size and disappeared completely a month after transplantation. The specific MPC-11 gammaglobulin could be detected in the serum of the hosts within 2 days after the transplantation and the changes in its concentration roughly correlated with the tumour size. The estimated half-life of the MPC-11 gammaglobulin in the circulation of the tumour-bearing hamsters was 4-6 days. Host resistance was demonstrated in tumour-bearing hamsters by their failure to develop tumours on second challenge with MPC-11 cells.

Optic atrophy.

A young woman became suddenly aware of visual loss in her left eye. She was found to have optic atrophy giving chronicity to the disease process. A hypopigmented macule on her face along with neuroimaging studies suggested an inflammatory process. A biopsy of the skin lesion was compatible with sarcoidosis. The patient responded to corticosteroid therapy.
