1066                GUMMATA OF LIVER (HEPAR LOBATUM)

No clinical information is available for this old specimen.  It is known that there was a patch of syphilitic aortitis at necropsy.

The specimen consists of several portions of liver and one of spleen.  Large stellate scars are present, producing irregular puckering of the surface.  They are also visible on the cut surface.  The liver substance itself appears approximately normal.  In the spleen an area of gummatous necrosis is visible as an opaque grey area measuring about 2 cm x 1 cm.  Histology shows central gummatous necrosis with a thick surrounding zone of chronic granulation tissue in which plasma cells are conspicuous and small and medium sized vessels show endarteritis.
