    Area of Science:

    • Histopathology
    • Biochemistry

    Background:

    • Melanin and hemosiderin are crucial pigments with distinct roles in biological systems.
    • Simultaneous or sequential visualization of these pigments aids in understanding pathological processes.

    Purpose of the Study:

    • To describe a novel histological procedure for the sequential staining of tissue sections.
    • To enable the combined detection of melanin and hemosiderin within the same tissue sample.

    Main Methods:

    • The study details a sequential staining protocol.
    • This involves applying the Fontana-Masson technique for melanin detection.
    • Followed by Perls' technique for hemosiderin identification.

    Main Results:

    • The described procedure allows for the successful successive staining of tissue sections.

  • Both melanin and hemosiderin can be visualized within the same specimen.
  • This confirms the feasibility of the sequential staining approach.

    • Conclusions:

    • A reliable method for sequential Fontana-Masson and Perls' staining has been established.
    • This technique offers a valuable tool for histopathological analysis.
    • It facilitates the differential diagnosis of conditions involving pigment accumulation.
