| Lyell's disease | <syndrome> A disease of infants due to group 2 phage type 17 staphylococci that produce an epidermolytic exotoxin. Superficial fine vesicles and bullae form and rupture easily, resulting in loss of large sheets of epidermis. (12 Dec 1998) |
| Lyell's syndrome | A syndrome in which a large portion of the skin becomes intensely erythematous with epidermal necrosis, and peels off in the manner of a second-degree burn, often simultaneous with the formation of flaccid bullae, resulting from drug sensitivity or of unknown cause; the level of separation is subepidermal, unlike staphylococcal scalded skin syndrome in which there is subcorneal change.
