What's new in adrenal gland pathology: WHO 5th edition for adrenal cortex

Area of Science:

• Endocrinology
• Oncology
• Pathology

Background:

• The World Health Organization (WHO) classification of tumors is a critical resource for diagnosing and understanding neoplasms.
• The 5th edition (2022) represents a significant update to the classification of endocrine and neuroendocrine tumors.
• Adrenal cortex tumors require updated diagnostic criteria and understanding in light of new research.

Purpose of the Study:

• To summarize the key changes in the 5th edition of the WHO Classification of Endocrine and Neuroendocrine Tumors.
• To focus specifically on the diagnostic and classification updates pertaining to the adrenal cortex.
• To provide endocrinologists and pathologists with a concise overview of recent advancements.

Main Methods:

• Review of the 5th edition of the WHO Classification of Endocrine and Neuroendocrine Tumors (2022).
• Identification and synthesis of changes related to adrenal cortex neoplasms.
• Comparative analysis with previous classifications where relevant.

Main Results:

• The 5th edition introduces revised terminology and grading systems for adrenal cortex tumors.
• New insights into the molecular basis of certain adrenal tumors are incorporated.
• Updated diagnostic criteria aim to improve diagnostic accuracy and patient stratification.

Conclusions:

• The 5th edition of the WHO classification provides crucial updates for adrenal cortex tumors.
• These changes are essential for accurate diagnosis, prognosis, and clinical management in daily endocrine practice.
• Adherence to the new classification will enhance consistency and understanding in the field.
