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.
毛发上皮瘤（马勒布钙化上皮瘤）是发生于真皮或皮下组织的良性软组织肿瘤；约40%见于10岁以下儿童。超过80%有镜下钙化和/或骨化。虽然X线可见钙化的发生率尚不清楚，但钙化严重的肿瘤有独特的X线表现。作者描述了2例毛发上皮瘤患儿的X线和病理表现。
