  1. 2. Stain positive for amyloid, showing apple-green birefringence under polarized light.
  2. 5. Stain that highlights acid-fast bacilli, used to diagnose tuberculosis.
  3. 6. Stain positive for iron, used in haemochromatosis.
  4. 9. Elevated in allergic reactions and parasitic infections, also seen in Hodgkin’s disease.
  5. 10. Stain that highlights cytoplasmic inclusions, useful for diagnosing Chlamydia psittaci.
  6. 15. Plasma cell malignancy linked to chronic inflammation.
  7. 16. Stain identical to Prussian blue, detects iron in haemochromatosis.
  8. 17. Stain used to detect copper, helpful in Wilson’s disease diagnosis.
  9. 20. Chronic inflammation and characteristic in lymphoma.
  10. 21. Technique using antibodies to detect specific antigens in tissue samples.
  11. 28. Key cells in chronic inflammation, also found in granulomas like Sarcoidosis.
  12. 29. Malignant tumour arising from epithelial cells.
  13. 30. Cancer of lymphoid tissues, often diagnosed with CD45 marker.

  1. 1. Marker for neuroendocrine tumours like insulinomas and pheochromocytomas.
  2. 3. Carcinoma type affecting the urinary tract, including bladder and kidney.
  3. 4. Pathogen detected using Gomori’s methenamine silver stain, causes pneumonia in immunocompromised patients.
  4. 7. First responders in acute inflammation, raised due to corticosteroid use.
  5. 8. Condition diagnosed using Congo Red staining, showing apple-green birefringence.
  6. 11. Aggressive skin cancer detected using Fontana stain.
  7. 12. Cancer originating from glandular epithelium, common in lung, breast, stomach, and colon.
  8. 13. Bacterium stained with Fite stain, causes leprosy.
  9. 14. Carcinoma type that produces keratin and forms intracellular bridges.
  10. 18. Stain used to detect melanin, useful in melanoma diagnosis.
  11. 19. Marker for epithelial cells, used to detect carcinomas.
  12. 22. Ink stain used to detect Cryptococcus neoformans, showing yeast cells with halos.
  13. 23. Marker for lymphoid cells in immunohistochemistry.
  14. 24. Cells associated with allergic reactions and parasitic infections.
  15. 25. Malignant tumour arising from connective tissues such as bone, muscle, and fat.
  16. 26. Cells involved in chronic inflammation and Myeloma.
  17. 27. Organised collection of epithelioid macrophages, found in conditions like tuberculosis and sarcoidosis.
