1 . An epileptic patient with Dupuytren's contracture of the palms, severe plantar fibromatosis, prominent knuckle pads, periarthritis of the shoulders and hyperplasia of the gums is described.

2. The plantar lesions recurred despite radical excision. The knuckle pads on one hand disappeared after radiotherapy.

3. The association of each of these conditions with epilepsy and with Dupuytren's contracture is reviewed, and it is suggested that the hyperplasia of the gums may be a hitherto unrecognised feature.

4. The characteristic histological appearances of the plantar lesions are described and the risk of confusion with fibrosarcoma is emphasised.
