title: Benign hidradenoma: magnetic resonance and ultrasound features of two cases.
abstract: Tumors of sweat gland origin are rare in the hand but should be considered in the differential diagnosis when certain imaging features are present. We present a case of nodular hidradenoma of the hand, with previously unreported magnetic resonance imaging features, and a further case in the thigh, both with ultrasound and histopathological correlation. The imaging literature of this tumor is reviewed, and its significance is discussed with respect to the current understanding of its malignant potential.
