Introduction
Nodular fasciitis is a
self-limited benign clonal process, clinically occurring in the
subcutis, composed of fibroblasts and myofibroblasts in a disorganized
tissue culture-like array (WHO classification of Skin Tumors, 2018). The
most common locations for the disease are the trunk, upper extremities,
head, and neck. [1]. Stewart FW first mentioned this disorder in
1944, but Konwaler et al. provided the first details described in 1955
[2]. It has since been described in multiple locations and can be
confused with leiomyosarcoma and nerve sheath tumors, so accurate
diagnosis is essentially independent of anatomic location.
