Abstract

In cancer patient neurological symptoms are mostly due to direct tumor effect or paraneoplastic syndromes. The diagnosis of rare diseases causing neurological symptoms is challenging, especially in a metastatic cancer patient. Here we discussed a metastatic lung cancer patient who presented with red urine and neurological symptoms. After exclusion of metastasis and paraneoplastic pathologies, the findings were associated with the diagnosis of porphyria. While our experience is giving clinical clues about a rare pathology, it also reminds us the importance of work up in the face of neurological symptoms in oncology patients.
