Background:
Bernard-Soulier Syndrome (BSS) is a rare congenital bleeding disorder characterized by thrombocytopenia. BSS causes bruising, epistaxis, gingival bleeding hemorrhage, post-partum bleeding, gastrointestinal bleeding and post-traumatic hemorrhage, but there is no report of hemoptysis in BSS.
Case Report:
A 14-year-old girl was referred to this center due to massive hemoptysis. Her chest X-ray revealed complete collapse of the left lung. Rigid bronchoscopy was performed and the intrabronchial clots were removed. Smear and culture of direct sputum was positive for Mycobacterium tuberculosis. She received anti-tuberculosis treatment. During treatment, she developed massive vaginal bleeding, because of drug interaction between rifampin and low dose contraceptive (LD), which she had been taking for control of massive menstrual bleeding. Her vaginal bleeding was controlled by platelet infusion and recombinant factor 7 infusion. After two months of anti-TB treatment, the sputum smear and culture examination became negative. One year after treatment, the pulmonary tuberculosis was completely cured and no hemoptysis occurred.
Conclusion:
When hemoptysis occurs in patients with BSS, other differential diagnoses should also be considered.

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 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.

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...
Pulmonary Tuberculosis IV
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
