<unk> , also called<unk> coid (from the Greek 'sark' and 'oid' meaning "flesh-like")  or Besnier-Boeck disease, is an immune system disorder characterised by non-caseating granulomas (small inflammatory nodules) that most commonly arises in young adults. The cause of the disease is still unknown.  Virtually any organ can be affected; however, granulomas most often appear in the lungs (D86.0) or the lymph nodes (D86.1). Symptoms can occasionally appear suddenly but usually appear gradually. The clinical course varies and ranges from asymptomatic disease that resolves spontaneously to a debilitating chronic condition that may lead to death.
