In a search of the recent available literature I found no reported instance of contact sensitivity to beef fat. Sulzberger and Morse1 and Ramirez and Eller2 reported cases of contact sensitivity to wool fat. Strictly speaking, hydrous wool fat is a wax consisting of the esters of various fatty acids and various monohydric solid alcohols called sterols. Other closely related lipins that have been shown to cause contact sensitivity are stearic acid, listed by Weber,3 and oleic acid, in a case reported by Hailey.4 The latter case is open to question, as the material that produced the dermatitis, turkey red oil, is usually sulphonated castor oil and contains numerous substances other than oleic acid.
The following instance is deemed worthy of report since the condition represents an industrial dermatosis apparently not hitherto recorded and probably not rare.
