Nodular fasciitis (NF) shows a cellular proliferation which leads to widening of the fascia. Frequently unilateral or more often bilateral disruption of the fascia, with an infiltrative pattern is present. Subcutaneous fascia and surrounding fat are involved. Superficially the cellular proliferation may extend into dermal connective tissue. Deeper muscular tissue may be involved, with transitional forms or purely intramuscular changes, compatible with proliferative myositis. Proliferative myositis is considered to be a deep-seated variant of NF with muscular involvement. Intramuscular myxoma may be thought of as an intramuscular and mucoid variant of NF. A bilateral infiltrative pattern was most frequently found at all levels; in cases with muscular involvement it was always present.
结节性筋膜炎（NF）表现为细胞增殖，导致筋膜增宽。常出现单侧或更常见的双侧筋膜破坏，并呈浸润性模式。皮下筋膜和周围脂肪受累。表面上，细胞增殖可延伸至真皮结缔组织。更深层的肌肉组织可能受累，出现过渡形式或纯粹的肌内改变，与增生性肌炎相符。增生性肌炎被认为是NF累及肌肉的深部变体。肌内黏液瘤可被视为NF的肌内和黏液样变体。双侧浸润性模式在各个层面最常出现；在累及肌肉的病例中总是存在。
