Histologic Tumour types.
Table 2 shows the histologic types of the tumours seen. The commonest
histologic tumour type was Rhabdomyosarcoma accounting for 73.2% of all
tumours while giant cell tumour of soft tissue and alveolar soft part
tumour were the least encountered (0.9% each). Among the 82 cases of
rhabdomyosarcomas, the embryonal variant was predominantly seen 67
(81.7%). Other variants documented were the alveolar 8(9.8%), and
pleomorphic 4(4.9%) variants, 3(3.7%) cases were classified as
rhabdomyosarcoma not otherwise specified (NOS). The vasoformative
sarcomas comprised 5 cases of Kaposi sarcoma and 1 case each of
angiosarcoma and haemangiopericytoma. Other types are as classified in
Table 2. There was no remarkable gender difference in the occurrence of
the tumour subtypes (Table 2). Males had 4 tumours more than the
females.
