Definition
(1) low grade fever, productive cough,
oral lesions appear as nodular, ulcerative or vegetative lesions on the buccal mucosa, gingiva, tongue, palate, and/or lips.

Definition
(1) resembles pneumonia:
high fever, chest pain, malaise, night sweats
(2) more common & may mimic TB.
cutaneous lesions - erythematous nodules that enlarge and ulcerate
oral - may resemble SCC
(3) acute and granulomatous inflammation,
8 to 20 microns, doubly refractile cell wall,
may see pseudoepitheliomatous hyperplasia |
