Laryngitis sicca (1 of 1)
Standard light view almost into the subglottis, showing that the yellow mucus crusts here are adherent primarily to the immediate under-surface of the cords, just below their free margins.
Pachyderma (1 of 3)
Pachyderma, here referring to the heaped up mucosa in the interarytenoid area, in a patient with laryngitis sicca.
Pachyderma (2 of 3)
Adducted (voicing) position. Note that the pachyderma does not interfere with closure of the cords. In this case, the pachyderma does not directly affect the patient’s voice, which is typical, but the more generalized inflammatory condition (see the redness of the cords) does.
Pachyderma (3 of 3)
Narrow-band lighting. This shows some stippled vascular markings, often seen with chronic inflammation or HPV infection.
