Congenital hemihypertrophy. Tendency to association with other abnormalities and/or tumors.
Nine cases of congenital hemihypertrophy of an entire half of the body ("true" hemihypertrophy) were investigated in relation to literature data. The left side was more often affected (7:2) and the abnormality was more frequent in females (5:4). Associated abnormalities were present in all cases: a single abnormality in 3 cases (mental retardation, iris heterochromia and, respectively, left foot gigantism) and 3 to 13 abnormalities in the other 6 cases. Prominent hemiface, asymmetric macroglossia on the affected side, unequally developed breasts, unilateral gigantism of the foot, iris heterochromia, duplication of the renal pelvis, were considered important signs which easily draw attention. Out of nine cases investigated, three presented associated tumors: two tumors, one cerebral (malignant ependymoma) and the other hepatic (cavernous hemangioma) in one case, hepatoblastoma in another case, and multiple skin angiomas in the affected side of the third one. The case presenting two tumors had also the greatest number (twelve) of associated abnormalities.
