Plaque-Like Myofibroblastic Tumor of Infancy: A New Case Report and Literature Review.

Plaque-like myofibroblastic tumor of infancy is a rare entity, with only a few reports described in the literature. Herein we present a new case of a nodular plaque-like lesion of the left lower back in an 18-month-old boy. The lesion might initially be thought to be a dermatofibroma, but the overall characteristics suggested the diagnosis of plaque-like myofibroblastic tumor of infancy. We also provide a summary of previous reports in the literature about this exceptional tumor.
