Cases of patients developing lymphoma and cutaneous neoplasms after long-term methotrexate therapy are well documented in the literature; however, there are no reported cases of other neoplasms resulting from methotrexate therapy. A 52-year-old woman who had been on methotrexate for 9 years for psoriatic arthritis was found to have abnormal liver function tests on screening. Investigation with ultrasound, CT scanning and MRCP showed a hilar cholangiocarcinoma and a synchronous right renal tumour. A left hemi-hepatectomy extended to segments 5 and 8 with the formation of a hepaticojejunostomy was performed for a poorly differentiated infiltrative hilar cholangiocarcinoma. This was combined with a right radical nephrectomy for a T1 renal cell adenocarcinoma. Postoperative vomiting was subsequently found to be due to hypercalcaemia and primary hyperparathyroidism. A parathyroid adenoma was later excised. It seems likely that treatment with methotrexate was causal in the development of these three non-cutaneous neoplasms-two malignant and one benign.
