To the Editor:—
Oral lesions in pityriasis rosea have been described previously although they are relatively uncommon and few dermatologists have had the opportunity to see them. Oral involvement may occur more often in children than adults.1 The eruption in the mouth, when it does occur, follows a course similar to that of the cutaneous involvement. In addition to areas of dermatitis, several instances of hemorrhagic lesions have been reported.2-4 This report illustrates a typical example of this lesion, and describes the microscopic findings of the oral lesions.
Report of a Case:—
This 18-year-old Negro male experienced, a localized scaling area on the side of the neck followed one week later by smaller, similar lesions on the neck, lower face, chest, back, abdomen, and arms. Most of them were oval shaped, located in the lines of cleavage, and ranged from a few millimeters to several centimeters in diameter.
