Pathologists face challenges diagnosing melanoma due to complex features and unreliable markers. Gene expression analysis offers a promising, objective alternative for diagnosing malignant and melanocytic neoplasms.

Area of Science:

  • Oncology
  • Pathology
  • Molecular Biology

Background:

  • Melanoma diagnosis is challenging for pathologists due to overlapping morphological features.
  • Current immunohistochemical markers show insufficient effectiveness for accurate diagnosis and differential diagnosis.
  • Histopathology faces limitations in distinguishing certain malignant neoplasms, including melanocytic ones.

Purpose of the Study:

  • To review modern alternative diagnostic methods for malignant tumors.
  • To explore gene expression assessment as a potential diagnostic tool.
  • To evaluate the future clinical application of molecular diagnostic tests in pathology.

Main Methods:

  • Review of current literature on diagnostic methods for malignant neoplasms.
  • Analysis of gene expression assessment techniques.
Keywords:
