Although often linked to autoimmune diseases, its association with spondyloarthropathy (SpA) is rare and poorly documented. A 33\u2010year\u2010old man with longstanding diarrhea and polyarthralgia was initially misdiagnosed with irritable bowel syndrome and fibromyalgia. After developing palmoplantar pustulosis and worsening musculoskeletal pain, repeat colonoscopy with biopsies confirmed CC. Imaging revealed sternal erosions and metatarsophalangeal effusions, supporting a diagnosis of SpA. Treatment with budesonide, mesalazine, and methotrexate provided partial improvement. A TNF\u2010\u03b1 inhibitor is being considered to target both intestinal and joint involvement. This case underscores the diagnostic complexity of CC and its potential association with SpA. Shared immune mechanisms suggest a common pathogenesis, highlighting the importance of multidisciplinary management for optimal care.<\/jats:p>","DOI":"10.1002\/ccr3.72580","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T14:37:52Z","timestamp":1777041472000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spondyloarthritis
