Detailed explanation-1: -Productive lesions or tubercles are granulomas, especially caseating granulomas. Exudative lesions are tuberculous pneumonia. Each occurred in multiple variations and progressed through a series of stages.
Detailed explanation-2: -Conclusion: why active TB takes place Exudative lesions are those which are able to form quickly enough to overcome the protective mechanism of the interlobular septae, which is the local structure that can stop both the local generation of new lesions and their coalescence into larger lesions.
Detailed explanation-3: -These are of two types; exudative lesions and productive lesions. Exudative lesions occur when the bacilli are many and virulent. Productive lesions are cellular in nature. Depending on the time of illness, tuberculosis may be classified as ‘primary’ and ‘post-primary’.
Detailed explanation-4: -Cutaneous involvement is a relatively uncommon manifestation of TB. The clinical findings vary and include papules, verrucous plaques, suppurative nodules, chronic ulcers, and other lesions.
Detailed explanation-5: -Histopathology remains one of the most important methods for diagnosing tuberculosis, especially in TB prevalent areas. It should be considered in the differential diagnosis of all respiratory diseases because of its varied clinical presentations and manifestations.
