Picture of the Month Quiz

A 15-year-old girl had red spots on her tongue. The spots had been present for approximately 1 year and bled a few times each month. The bleeding generally lasted for 10 to 15 minutes and stopped with minimal pressure on the lesion. The lesions had not changed color or size. They blanched with pressure. Figure 1 shows the lesions on her tongue. She had several similar lesions on her lips.

Her medical history was significant for frequent nosebleeds. They occurred spontaneously several times a week and sometimes lasted 20 to 30 minutes. She had no other history of bleeding problems. There was a history of recurrent nosebleeds and fatal internal hemorrhage in her father's family. Examination of the patient's father showed similar lesions on his nasal mucosa (Figure 2).
