Atypical Mycobacterial Lymphadenitis
September 14, 2005
After 3 months of seeing this painless mass at the angle of the 3-year-old's left jaw, his parents sought medical advice for their son. The youngster had no constitutional symptoms. A Mantoux test was performed, and an erythematous, indurated area measuring 15 mm in diameter was found at the test site 48 hours later.
