A case of renal lymphangioma with a karyotype 45,X,-X,i dic(7q).
Cytogenetic analysis of a polycystic unilateral renal lymphangioma was performed by short-term culture and banding methods. The tumor's cells showed an isochromosome of the long arm of chromosome #7 and monosomy of X chromosome, whereas the peripheral lymphocytes stimulated with phytohemagglutinin showed a normal female karyotype, 46,XX. These karyotypic anomalies suggest that lymphangioma, although clinically benign, may have malignant potential.
