XXXX and autoimmunity markers in an adolescent with @entity12692 .

@entity1 @entity32 @entity650 @entity417 @entity419 @entity12692 @entity5506 @entity68
We describe herein the case of an adolescent @entity1 with @entity417 non-responsive to oral @entity68 , associated with low-grade fever, diminished appetite and fatigue. A palpable mass below the xiphoid was noted. Laboratory findings were consistent with @entity417 of @entity32 . Direct antiglobulin test was positive without any other evidence of @entity5506 . Other autoantibodies, such as anti-thyroid and anti-nuclear antibodies, were also positive. After thorough investigation, @entity12692 was the most likely diagnosis on the basis of high serum @entity650 and the magnetic resonance imaging findings. @entity419 positron emission tomography-computed tomography showed a localized hypermetabolic mass, which was resected. @entity12692 of plasma type was identified on histology. Hemogloblin and @entity650 gradually returned to normal, whereas positive autoantibodies became negative. This case emphasizes the need to investigate thoroughly for the underlying cause of @entity417 of @entity32 and to include @entity12692 in the differential diagnosis, on the measurement of @entity650 .
