Key result
Renal cell carcinoma rarely presents as isolated pulmonary lymphangitic carcinomatosis without nodules or mediastinal lymphadenopathy.
Why the study?

Case Report (n=1)
This case highlights a rare presentation of renal cell carcinoma as isolated pulmonary lymphangitic carcinomatosis without nodules or mediastinal lymphadenopathy.
Liu et al. (2026) conducted a case report in Pulmonary lymphangitic carcinomatosis from renal cell carcinoma (n=1). A 68-year-old man presented with a rare case of isolated pulmonary lymphangitic carcinomatosis without nodules or mediastinal lymphadenopathy as the initial manifestation of renal cell carcinoma.
