Background: Elderly giant retrosternal thyroid goiter is a rare yet significant medical condition, often presenting clinical symptoms that can be confused with other diseases, posing diagnostic and therapeutic challenges. This study aims to delve into the characteristics and potential mechanisms of this ailment through pathological diagnosis and immunohistochemical analysis, providing clinicians with more precise diagnostic and treatment strategies.
Case Summary: A 77-year-old male, was admitted to hospital with the chief complaint of finding a goiter in the semilunar month during physical examination, accompanied by dyspnea.
Background: Minute Pulmonary Meningothelial-like Nodules (MPMNs) are rare benign pulmonary nodules, which are more common in elderly women and have a higher detection rate in lung tissues of patients with lung malignant diseases.

Aim: To construct the fusion gene of Hsp65 of Mycobacterium tuberculosis H37Rv and enhanced green fluorescence protein (EGFP) and prepare dendritic cell (DC) vaccine.
Methods: Hsp65 DNA amplified by PCR was cloned into eukaryotic expression vector EGFP-C1. The recombinant plasmid pEGHsp65 was subsequently transfected into Hela cells, and the transfection rate was determined under confocal laser scanning fluorescence microscope at different times.
