RESUMO
A case of hereditary hemorrhagic telangiectasia with prominent nodular transformation of the liver is described. The presence of enlarged arteries was documented morphometrically. Artery-to-portal vein shunts were also found. The association of abnormal vessels with hepatic nodules supports the hypothesis that abnormalities of blood flow cause nodular transformation. Nodular transformation may be the lesion that has heretofore been termed cirrhosis hepatis telangiectasia or atypical cirrhosis.

Although odontogenic keratocysts are benign they are often locally destructive and tend to recur after conservative surgical treatment. They must therefore be distinguished from other cysts of the jaw. Keratocysts possess outpouchings and microscopic daughter cysts from which recurrences may arise. Histologic examination is essential for diagnosis since the appearances on roentgenograms and at operation usually do not reveal the true nature of the lesion. Since many nondental surgeons and pathologists are unaware of odontogenic keratocysts a case is presented in which surgical treatment was originally conservative and finally relatively radical.

This article presents a young girl who developed jaundice while on oral contraceptives. A most significant feature in this particular patient's history was the severe pruritus she developed during a previous gestation. This combination of events should alert physicians to the possible diagnosis. Oral contraceptives should be prescribed to such a patient with great caution.
