The Unlikely Duo: Tuberculous Lymphadenitis Leading to Secondary Amyloidosis in a Young Patient.

Amyloidosis is an extremely rare condition with a variety of symptoms that, in extreme situations, can be fatal. Basically a protein misfolding disorder, it is characterized by deposition of insoluble polymeric protein fibrils in tissues and organs.
