MEN1 Syndrome and Hibernoma: An Uncommonly Recognised Association?

Area of Science:

• Endocrinology
• Oncology
• Genetics

Background:

• Multiple endocrine neoplasia type 1 (MEN1) syndrome classically involves parathyroid, pituitary, and pancreatic tumors.
• The association of MEN1 syndrome with hibernoma, a benign brown fat tumor, is less recognized.
• Both MEN1 syndrome and hibernoma share a genetic link to MEN1 gene deletion.

Purpose of the Study:

• To describe a rare case of MEN1 syndrome associated with hibernoma.
• To detail the radiological and pathological findings of this association.
• To enhance understanding of the less common manifestations of MEN1 syndrome.

Main Methods:

• Case report detailing clinical presentation.
• Review of radiological imaging.
• Pathological examination of tumor tissue.

Main Results:

• The case presented key radiological and pathological features supporting the association.
• Genetic analysis confirmed the link via MEN1 gene deletion.
• Hibernoma was identified as a potential, albeit rare, manifestation.

Conclusions:

• MEN1 syndrome may be associated with hibernomas, expanding the spectrum of known MEN1-related tumors.
• The shared genetic basis involving the MEN1 gene underscores this connection.
• Further research is warranted to elucidate the mechanisms and prevalence.
