Summary
This study presents a rare case of atypical lung carcinoid with a unique three-cell type composition and immunohistochemical profile. Notably, it describes the first instance of atypical carcinoid cells expressing glial fibrillary acidic protein (GFAP).
Area of Science:
- Oncology
- Pathology
- Cell Biology
Background:
- Atypical carcinoid tumors are rare neuroendocrine neoplasms.
- Understanding their cellular heterogeneity and molecular markers is crucial for diagnosis and treatment.
- Previous studies have not extensively detailed cases with complex cellular compositions and unusual protein expression.
