Infantile myofibromatosis: multiple firm nodules in a premature newborn

Dermatol Online J. 2021 Nov 15;27(11). doi: 10.5070/D3271156092.

Abstract

Infantile myofibromatosis is a rare myofibroblastic proliferative disorder characterized by firm, skin-colored to red-purple cutaneous and subcutaneous nodules; these are the most prevalent fibrous tumors observed in infancy. A premature male infant presented at birth with multiple subcutaneous firm skin-colored nodules measuring about 1-2cm each. Full body MRI and excisional biopsy of the right chest nodule confirmed the diagnosis. We review the case of infantile myofibromatosis and discuss its highly heterogeneous presentation and clinical course, as well as histopathology, genetic testing, and approaches to management.
