Ak. Elnaggar et al., TRISOMY-5 AS THE SOLE CHROMOSOMAL ABNORMALITY IN A PRIMARY MUCOEPIDERMOID CARCINOMA OF THE MINOR SALIVARY-GLAND, Cancer genetics and cytogenetics, 76(2), 1994, pp. 96-99
We describe the cytogenetic findings in a moderately differentiated pr
imary mucoepidermoid carcinoma of the base of the tongue. The only kar
yotypic abnormality found in the primary culture of this neoplasm was
trisomy 5. This finding is remarkably different from previous cytogene
tic studies of mucoepidermoid carcinomas, which have shown heterogeneo
us and unrelated chromosomal aberrations. Our results suggest that tri
somy 5 may be an early aberration in the development of this neoplasm.
