Subcutaneous Pseudosarcomatous Fibromatosis (Fasciitis)

Clinical Pathologic Conference Case 3: Nodular Fasciitis

“…Acute, severe pain or paresthesia are rare, but may occasionally occur when the rapidly growing nodule puts pressure on an adjacent peripheral nerve. Nodular fasciitis was first described by Konwaler in 1955 as a ''subcutaneous pseudosarcomatous fibromatosis [16].'' Because of its rapid growth, cellularity, and active mitotic rate, Weiss and Goldblum call it the most common benign mesenchymal lesion that is misdiagnosed as a sarcoma [13].…”

A Rare Nodular Fasciitis Involving the Finger: A Case Report

“…Nodular fasciitis, first reported by Konwaler in 1955, is a rapidly growing lesion of benign fibroblastic tissue [5]. The lesion has been often misdiagnosed as malignant neoplasm in clinical practice due to its rapid growth, rich cellularity, and high mitotic activity [2,3].…”

“…Although it is frequently found in the forearm, the lesion distal to the wrist, especially of the finger, is quite rare [3][4][5][6][7][8]. A case of nodular fasciitis involving the finger is reported with brief review of its clinicopathological features.…”

Nodular fasciitis: a rare case report type of article

“…1 It is a rare benign neoplasm most commonly afflicting the soft tissues of upper extremity followed by trunk, head, and neck. The upper extremity is the most common location (34%), followed by the head and neck region (24%), trunk (21%), and lower extremity (14%).…”
