XXXX of the cranial vault: case report.

@entity1712 @entity4890 @entity1 @entity82 @entity13626 @entity20393 @entity2695 @entity5 @entity75 @entity1222 @entity4034 @entity1492 @entity79 @entity1653 @entity14972 @entity3 @entity361
@entity14972 is a @entity361 of early childhood characterized by the formation of @entity5 in the skin, muscle, viscera, bone, and subcutaneous tissue. Although relatively rare overall, it represents the most common @entity5 of infancy. The etiology of this disorder is unknown. @entity14972 can present as a solitary or multicentric form. With the multicentric form, bone is often involved, but solitary @entity79 account for only 10% of the cases. Imaging findings are not pathognomonic, and the differential diagnosis usually includes @entity1712 ( @entity1222 ), @entity4034 , @entity3 , @entity13626 , @entity4890 , @entity2695 , @entity82 , @entity1492 , and @entity1653 . A histological pattern is typical, but there are no histopathological differences between the solitary and multicentric forms. @entity75 generally have a favorable prognosis if totally removed, with a 10% recurrence rate; incompletely resected lesions recur. We report the case of a 9-year-old @entity1 who came to our attention with a solitary infantile @entity20393 of the calvarium, appearing as a tight-elastic, lightly tender mass in the left frontal area, eroding both the inner and the outer tables. Histopathologically, the specimens showed a spindle-cell @entity5 with dense reticulin fiber network and expression of smooth muscle actin. Fifty-eight months MR follow-up after total removal showed no residual or relapse.
