Should patients always seek a secondary tissue confirmation after receiving a concerning medical imaging result?
Doctors in South Korea reported a case where a 79-year-old man was diagnosed with diffuse pulmonary lymphangiomatosis (DPL) after initial scans suggested lung cancer. Published on July 8, 2026, the report highlights an unusual presentation of this rare condition in an older adult.
Why it matters
Distinguishing between rare lymphatic disorders and malignancy is critical to avoid unnecessary interventions, as this case demonstrates that some diagnoses may improve without targeted therapy.
A case report from Jeonbuk National University Hospital detailed a 79-year-old man whose DPL diagnosis was confirmed via surgical biopsy and tissue staining. While DPL typically presents in youth, this patient remained stable for one year without disease recurrence.
The players
Jeonbuk National University Hospital
A medical facility in South Korea where the clinical team diagnosed and managed the patient.
BMC Pulmonary Medicine
A peer-reviewed journal that published the findings regarding the patient's unusual clinical course.
The details
The diagnosis was confirmed using video-assisted thoracoscopic surgery with wedge resection, which allowed for tissue analysis after needle aspirations failed to provide results. Staining for D2-40 and CD31 proteins proved essential to identify the lymphatic proliferation that mimics lung nodules and pleural effusions seen in cancer cases.
Timeline
2019 report noted DPL typically presents in youth.
2025 case report described DPL in a 17-year-old.

Health Landscape
Diffuse pulmonary lymphangiomatosis is a rare disorder historically associated with younger populations. This case marks a departure from established clinical expectations by documenting the condition in an elderly patient.
When facing complex lung findings that remain inconclusive after initial biopsies, patients should consult with specialists regarding whether additional surgical tissue sampling is appropriate. Understanding that symptoms may occasionally resolve without aggressive treatment underscores the importance of thorough diagnostic confirmation.
The takeaway
This case highlights the importance of precise tissue diagnosis when imaging findings are ambiguous, as not all lung nodule presentations require aggressive treatment. Always discuss the results of biopsy procedures with a pulmonologist to ensure the diagnosis aligns with the full clinical picture.
