Minocycline-induced Sweet's syndrome.
This is the second reported case of minocycline-induced Sweet's syndrome (and the first such case to appear in the American literature). The syndrome developed in a 32-year-old man 10 days after minocycline therapy for acne was begun and resolved rapidly after discontinuation of the medication and start of oral prednisone therapy.

Hemothorax and hemopericardium in a patient with Bean's blue rubber bleb nevus syndrome.
A patient with Bean's blue rubber bleb nevus syndrome presented with a hemothorax, and 18 years earlier had presented with "idiopathic" hemopercardium and tamponade. Typical hemangiomas were found in the pleura and skin. This is the first report of intrathoracic bleeding with this disorder.

Familial lichen planus.
We observed the simultaneous occurrence of generalized lichen planus in a woman and her mother. Both patients improved after therapy with topical steroid and salicylic acid ointment. Of the eighty-one cases of familial lichen planus previously reported, the vast majority (89 percent) occurred in blood relatives. The intervals of onset between familial cases were long, ranging from six weeks to thirty years (mean 73.4 months). These observations suggest that familial lichen planus may result from genetic predisposition, rather than from an infectious cause.

Eruptive vascular tumors associated with chronic graft-versus-host disease.
We report the occurrence of benign angiomatous and mesenchymal tumors following chronic graft-versus-host disease. Our patient is a 23-year-old man who had undergone allogenic bone marrow transplantation for chronic myelogenous leukemia in 1978. Over the past 3 years he has developed poikiloderma and sclerodermatous tightening of the upper and lower extremities. From 1981 until the present time, violaceous to black friable tumors have erupted on the lower extremities. Histopathologic findings show an active mesenchymal and vascular tumorous response of variable-sized channels.

Dedifferentiation of a transplantable papillary thyroid carcinoma over a 15-year period.
Fischer 344 rats on a prolonged low-iodine diet developed thyroid nodules which were transplanted subcutaneously into 33 thyroidectomized rats. One graft took and gave a papillary carcinoma. Serially transplanted syngeneically at 3- to 4-month intervals, it became autonomous in third generation hosts. With electron microscopy examination it was microfollicular in year 8 and anaplastic, with totally unpolarized epithelial cells, in year 15. Basement membrane present in year 1 was no longer visible in specimens of years 8 and 15. Tight and gap junctions still present in year 8 were absent in year 15, although a few desmosomes persisted. From years 8 to 15, free ribosomes and microfilaments became more frequent, whereas the number of mitochondria and the development of the Golgi complex declined.
