Abstract:
A 42-year-old female presented with a history of receiving PPD on right forearm intradermally before two days. Patient started having itching and irritation within a few hours and pain, oedema and vesicles formation by next day at the injection site. On examination, the whole right forearm was oedematous with induration of size 50 mm x 50 mm around the site of injection. Tubercular infection was suspected and the patient was subjected to further investigation but nothing, including physical examination, hemogram, fundus examination, chest X-ray, USG abdomen and CT thorax, was found suggestive of tuberculosis, leading to a diagnosis of LTBI.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
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 V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
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.
