Retrospective study on 515 cases misdiagnosed as neuroendocrine neoplasms from a pathologic consultation center

#3434

Introduction: Recent progress in the diagnosis and classification of Neuroendocrine Neoplasms (NENs) is achieved. However, the histological morphology and immunohistochemistry of NENs overlap with other lesions, and the differential diagnosis in clinical practice faces many challenges.

Aim(s): We re-evaluated the consultation cases misdiagnosed as NENs, attempted to highlight the diagnostic pitfalls of NENs.

Materials and methods: A total of 515 misdiagnosed cases were collected in FDSCC pathologic consultation center from 2013 to 2021. The pathological and immunochemistry features were reviewed.
