Abstract:
The clinicopathological and
immunohistochemical features of 7 cases of
peripheral neuroectodermal tumour were
documented. Children and adults were affected.
The tumours were found in both bone and soft
tissue. All tumours were positive for neurone
specific enolase. Some were positive for PGP 9.5
neurofilaments and O-13, in addition.
Cytoplasmic glycogen was variable. Some
tumours showed good neural differentiation. In
general the tumours had an aggressive
behaviour.
