Insights

Pulmonary Langerhans

Area of Science:

  • Pulmonary pathology
  • Histopathology
  • Immunohistochemistry

Context:

  • Pulmonary Langerhans' cell histiocytosis (PLCH) is a rare lung disease.
  • Accurate diagnosis is crucial for patient management.

Purpose:

  • To analyze morphologic findings of PLCH.
  • To identify key diagnostic features.

Summary:

  • H&E staining and immunohistochemistry were performed on 7 PLCH cases.
  • Langerhan's cell infiltration was observed in all cases.
  • Immunohistochemistry revealed S-100, CD68, and CD1a expression.

Impact:

  • Definitive diagnosis of PLCH requires pulmonary biopsy.
  • S-100 and CD1a immunostaining aids in PLCH diagnosis.

Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
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...
