title: Congenital infiltrative lipomas in a calf.
abstract: The current report describes a case of congenital subcutaneous and intramuscular tumors of the neck and tail base in a 4-week-old female Angus-Charolais crossbred calf. Results of clinical and ultrasound examination are summarized. Biopsy and necropsy findings indicated an infiltrative lipoma. Congenital lipomas are uncommon tumors in bovids. Clinical and morphologic differentials, as well as classification and the possible pathogenesis of congenital neoplasms, are discussed.
