@entity1 @entity738 @entity79 @entity3061 @entity292 @entity158 @entity370
BACKGROUND: @entity370 is a @entity738 that may affect any organ of the body. The most frequent loci of manifestation are the lungs. However, there are individual cases where bones are affected. The literature describes cases in which swelling or @entity292 were the first findings of a @entity79 . This is the first case reporting an @entity3061 in both angles of the mandibles which led to the diagnosis of @entity370 with multi-organ involvement. CASE PRESENTATION: The authors present a 74  years old European female @entity1 without previous diagnosis of @entity370 who presented with @entity158 in the area of the jaw angles. There were no further clinical symptoms. Bone biopsy following radiological investigation demonstrated non-caseating @entity738 consistent with @entity370 of the bone. Further evaluation confirmed multi-organ disease with involvement of lungs, intrathoracic lymph nodes, and the central nervous system. CONCLUSION: This case report shows that diagnosis of a severe disease can be missed if systematic clinical signs are not given. Furthermore, an accurate anamnesis and examination is required to receive an early diagnosis which often needs an interdisciplinary approach.
