Abstract:
Recurrent respiratory papillomatosis is the most common neoplasm of the larynx in childhood. Extension into lung parenchyma occurs in less than 1% of patients and has a low risk of malignant transformation. Treatment options for intrapulmonary spread have shown limited success. We describe a case of recurrent respiratory papillomatosis with extensive parenchymal involvement and adenosquamous carcinoma in a 14-year-old girl.

Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
