Abstract:

Objective

To investigate the clinical manifestations, imaging features and pathological characteristics of primary pulmonary mucinous adenocarcinoma (PPMA) and improve the understanding of the disease.

Methods

Through the clinical diagnosis and treatment of 3 cases of primary mucinous lung adenocarcinoma from June 2022 to October 2022 was analyzed. All of them were female, aged 73 to 85 old. Combined with literature analysis and literature review, to strengthen clinicians′understanding of the clinical manifestations, imaging characteristics and pathological characteristics of this disease, improve the level of diagnosis and treatment.

Results

The primary mucinous adenocarcinoma of the lung was mainly invasive mucinous adenocarcinoma. The clinical manifestations were not specific, and it was easy to be misdiagnosed. The diagnosis mainly depended on pathology, and the treatment was mainly early operation.

Conclusion

PPMA is a special subtype of lung adenocarcinoma with low incidence and poor prognosis. The lack of specificity in clinical diagnosis mainly depends on biopsy.

Key words: Primary mucinous lung adenocarcinoma, Invasive mucinous adenocarcinoma, Literature review
