Key result
Right lower lobectomy treats rare primary pulmonary low-grade fibromyxoid sarcoma diagnosed via MUC4 expression.
Why the study?
Primary pulmonary low-grade fibromyxoid sarcoma is a rare diagnostic entity requiring careful differentiation from metastatic disease and integration of multiple diagnostic modalities.
Population
70-year-old woman with a slowly enlarging right lower lobe pulmonary mass

MUC4 staining may aid diagnosis of rare pulmonary sarcomas; leaves open whether this alters management in broader populations.
Case Report (n=1)
This case highlights the diagnostic utility of diffuse MUC4 expression in identifying rare primary pulmonary low-grade fibromyxoid sarcoma and distinguishing it from metastatic disease.
Do et al. (2026) conducted a case report in Primary pulmonary low-grade fibromyxoid sarcoma (n=1). Right lower lobectomy and immunohistochemical evaluation was evaluated. A 70-year-old woman with a slowly enlarging pulmonary mass was diagnosed with rare primary pulmonary low-grade fibromyxoid sarcoma using MUC4 expression and treated with a right lower lobectomy.
