title: Cytologic features of fibromatosis colli of infancy.
abstract: OBJECTIVE
  To present the characteristic cytologic features of fibromatosis colli in infancy.
  
  
  METHODS
  A series of 14 children with the typical clinical presentation of fibromatosis colli of infancy on whom fine needle aspiration had been performed.
  
  
  RESULTS
  The cytologic features were identical in all cases. All samples contained degenerated muscle cells in varying numbers, including multinucleated cells with abundant cytoplasm. Fibroblasts appeared mainly as single cells but with admixed clusters of varying sizes. The cells were slender, spindle shaped or somewhat rounded, with benign nuclear characteristics.
  
  
  CONCLUSIONS
  In the typical clinical setting and with the cytologic findings above, surgical biopsy of the lesion may be avoided.
