SANGUINEOUS   CYSTS.  411

Occasionally,  one  meets  with  sanguineous  cysts,  -vvliicli  derive  a
peculiar  aspect  from  a  columnar  or  fasciculated  structure  of  their  in-
terior, making  them  look  like  the  right  auricle  of  a  heart.  This  "was
singularly  the  case  in  one  which  I  assisted  Mr.  Macilwain  in  removing
from  over  the  lower  angle  of  the  scapula  of  a  lad  fifteen  years  old.  It
had  existed  more  than  eight  years,  and  grew  rapidly,  while,  in  the  last
year,  he  was  actively  at  work.  It  was  now  also  painful.  It  felt  like  a
fatty  tumour,  but  proved  to  be  a  cyst  thus  fasciculated  like  an  auricle,
with  a  finely  polished  internal  surface,  and  containing  about  an  ounce
and  a  half  of  liquid  blood.  Its  walls  were  from  one  to  two  lines  in
thickness,  and  seemed  in  great  part  made  up  of  small  cells,  such  as
one  sees  in  a  bronchocele,  full  of  serous  and  bloody  fluids.  No  trouble
followed  the  operation,  and  the  patient  remained  well  twelve  years
after  it.^

A  cyst  presenting  the  same  peculiarity  of  internal  surface  was  re-
moved by  Mr.  Stanley,  in  October  1848,  from  over  the  pubes  of  a  boy
thirteen  years  old.  It  was  observed  increasing  for  nine  months,  and
part  of  it,  consisting  of  a  simple  thin-wsiled  serous  cyst,  was  trans-
parent ;  but  behind,  and  projecting  into  this.  Was  a  more  thickly- walled
cyst,  containing  about  a  drachm  of  dark  liquid  blood,  and  on  its  sur-
face fasciculated  and  polished  like  an  auricle.  Its  Walls  were  well  de-
fined, formed  of  connective  tissue  imperfectly  filamentous  and  nucleated,
and  I  could  find  no  epithelium  lining  it.     The  operation  was  successful.
