Misdiagnosed Cancer Turned Out to Be Curable Lymphoma
12 Mar
Summary
- A rare bile duct cancer diagnosis was a misdiagnosis.
- The actual tumor was a rare type of lymphoma.
- The lymphoma was successfully treated, offering a cure.

A misdiagnosis of cholangiocarcinoma led to a failed liver transplant evaluation for a 42-year-old man. Initial tests suggested a grim prognosis with a very low survival rate for bile duct cancer. The situation was dire, prompting discussions about end-of-life care and the possibility of palliative chemotherapy.
Further investigation and a biopsy at the Mayo Clinic revealed a surprising truth: the tumor was not bile duct cancer but a rare type of non-Hodgkin lymphoma. This discovery offered a critical shift, as lymphoma, unlike cholangiocarcinoma, was curable with available treatments.
The patient underwent six rounds of chemotherapy over four months. By early 2025, he had passed the two-year post-treatment milestone with no signs of recurrence, marking a successful recovery and the obliteration of the tumor.
