Ulcerative colitis associated mononeuritis multiplex in 75-year-old patient: Rare case report.

Inflammatory bowel disease (IBD) refers to a collection of chronic, idiopathic inflammatory/autoimmune disorders of the gastrointestinal tract characterized by relapsing and remitting episodes. In this case report, we will report a patient who has encountered ulcerative colitis related to mononeuritis multiplex as a rare clinical scenario. A 75-year-old male patient, with a prior medical history including long-standing hypertension, recurring episodes of peripheral joint arthritis, leg skin lesions reminiscent of erythema nodosum, and persistent chronic diarrhea over the past 2 years, was recently hospitalized at the rheumatology department of Imam Reza Hospital in Tabriz.
