Lymphangitis carcinomatosa: An unusual manifestation of transitional cell carcinoma: A case report

Uroepithelial TCC most commonly presents with painless gross or microscopic hematuria or less commonly with ureteral obstruction and pain secondary to clots in pelviureteric tumors and dysuria, frequency and pelvic pain in bladder tumos. Metastasis occurs later in the course of disease. Discrete nodular form of metastasis to lungs is known to occur in TCC however an isolated lymphangitis carcinomatosa type picture in lungs is being reported for the first time. In our case it changed the clinical presentation dramatically making it difficult to reach the primary diagnosis.
