We present details of nine patients who developed morphoea after radiotherapy. In every patient morphoea began within the irradiated area and in four spread beyond it. We believe the irradiation triggered the morphoea despite the absence of any clear-cut relationship to dosage or severity of the acute reaction. Dermatologists and radiation oncologists should be aware that this condition may lead to the mistaken diagnosis of a local tumour recurrence.

Fifteen patients with a variety of itching skin diseases (atopic eczema, dermatitis herpetiformis, lichen planus, urticaria and psoriasis) have been studied in the sleep laboratory. Recordings were made of all-night electroencephalogram, electro-oculogram, submental electromyogram, and muscle potentials from both forearms. Bouts of scratching during orthodox (NREM) sleep occurred more frequently in stages 1 and 2 than in stages 3 and 4. The frequency in paradoxial (REM) sleep was close to that in stage 2 sleep. This pattern was similar for all the diseases studied and seems to be related to the physiology of the sleep stages rather than to the skin diseases themselves. The mean duration of the bouts of scratching was not related to the sleep stage in which they started.
