Bile emboli: a complication of PTD.

Bile emboli in the kidneys and lungs were present at autopsy in a patient who had undergone percutaneous trans-hepatic drainage for pancreatic carcinoma obstructing the common bile duct. The patient also developed hemobilia and bile peritonitis.

Pilomatrixoma (calcifying epithelioma of Malherbe): radiographic features.

Pilomatrixomas (calcifying epitheliomas of Malherbe) are benign soft-tissue tumors that occur in the dermis or subcutaneous tissues; about 40% are found in children under 10 years of age. More than 80% have microscopic calcification and/or ossification. Although the incidence of radiographically visible calcification is not known, heavily calcified tumors have a distinctive radiographic appearance. The authors describe the radiographic and pathologic findings in 2 children with pilomatrixomas.
