Epitheloid cells are characteristic of:
1. Chronic Infection
2. Granulation tissue
3. Granulomatous Inflammation
4. Only In tuberculosis

Pathology
In thalassemia the microscopic picture of RBCs is:
1. Microcytic, hypo chromic and target cells present
2. Macrocytic, hypochromic and target cell present
3. Microcytic. hypochromic and target cell absent
4. Macrocytic. hypochromic and target cells absent

📝 Explanation:

Mcroscopic picture of red blood cells (RBCs) in thalassemia, the following characteristics are typically observed:

  1. Microcytic: The RBCs are smaller than normal (microcytic) due to the reduced hemoglobin content.
  2. Hypochromic: The RBCs have a lower concentration of hemoglobin, leading to a paler appearance (hypochromic).
  3. Target cells: These are RBCs that have a bullseye appearance due to an abnormal distribution of hemoglobin within the cell. Target cells are often seen in thalassemia due to the imbalance of globin chains and the resultant membrane changes.
