Related to nodular fasciitis: fibromatosis, myositis ossificans


inflammation of a fascia.
necrotizing fasciitis a fulminating group A streptococcal infection beginning with severe or extensive cellulitis that spreads to involve the superficial and deep fascia, producing thrombosis of the subcutaneous vessels and gangrene of the underlying tissues. A cutaneous lesion usually serves as a portal of entry for the infection, but sometimes no such lesion is found.
nodular fasciitis (proliferative fasciitis) a benign, reactive proliferation of fibroblasts in the subcutaneous tissues and commonly associated with the deep fascia.
pseudosarcomatous fasciitis a benign soft tissue tumor occurring subcutaneously and sometimes arising from deep muscle and fascia.

nod·u·lar fas·ci·i·tis

a rapidly growing tumorlike proliferation of fibroblasts, not thought to be neoplastic, with mild inflammatory exudation occurring in fascia; the fibrosis may infiltrate surrounding tissue but does not progress indefinitely or metastasize.

nodular fasciitis

A benign, rapidly growing reactive proliferation of fibroblasts in the deep dermis/subcutis on the arms, trunk, or neck of young adults (mean age 34), usually measuring < 3 cm.

Nodular fasciitis is an uncommon tumor-like fibroblastic proliferation of the head and neck that is difficult to differentiate from its more malignant counterparts.
Exuberant, extensive scars, reactive spindle cell nodules, and nodular fasciitis are reactive entities that may mimic FLSCC.
The differential diagnosis for infantile myofibromatosis includes other types of fibromatosis, congenital infantile fibrosarcoma, infantile hemangiopericytoma, inflammatory myofibroblastic tumors, fibrohistiocytic tumors with a predominantly fibrous pattern, smooth muscle tumors such as leiomyomas and leiomyosarcomas, neurogenic tumors such as neurofibromas and low-grade malignant peripheral nerve sheath tumors, and nodular fasciitis.
Other cutaneous and subcutaneous lesions that are considered in the differential diagnosis include leiomyoma, hemangiopericytoma, fibrous hamartoma of infancy, cutaneous inflammatory pseudotumor, desmoid tumor, nodular fasciitis, plexiform fibrohistioeytic tumor, neurofibroma, and dermatomyofibroma.
Other breast lesions that may exhibit myxoid features include myxoid stromal change, myxoid fibroadenoma, myxoid nerve sheath tumors, myxoid dermatofibrosarcoma protuberans, myxomas, and myxoid foci in nodular fasciitis. Heterologous elements such as bone formation can be seen in the breast in hamartomas, calcified fibroadenoma, and osseous metaplasia in benign mesenchymal lesions such as lipoma or leiomyoma and in malignant lesions such as phyllodes tumor, metaplastic spindle cell carcinoma, matrix-producing carcinoma, sarcomas, and malignant adenomyoepithelioma with osteogenic differentiation.
