nodular fasciitis

(redirected from nodular pseudosarcomatous fasciits)

fasciitis

 [fas″e-i´tis]
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

an inflammation of the fascia that causes the formation of nodules.

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. 

DiffDx
Dermatofibroma, DFSP, other fasciitides (fibroma of tendon sheath, intravascular, parosteal), fibromatosis, fibrosarcoma, fibrous histiocytoma, inflammatory myofibroblastic tumour, leiomyosarcoma, myxoid tumours, spindle-cell sarcoma.

nodular

marked with, or resembling, nodules.

nodular dermatofibrosis
nodular episcleritis
see nodular fasciitis (below).
nodular fasciitis
a firm painless nodular swelling, 0.25 to 0.5 inch diameter, under the conjunctiva at the corneoscleral junction of the eye in dogs. Alternative sites for lesions are the nictitating membrane, and in the subcutis anywhere in the body and in deeper fascia and muscles of the head, face and eyelid. The lesion is an inflammation of fascia and not a neoplasm but acts in a similar manner and may require enucleation because of its size. Called also nodular episcleritis, collie granuloma and proliferative keratoconjunctivitis.
nodular hyperplasia
a characteristic lesion in nodular regeneration in the liver.
nodular infiltrates
cells aggregated in one site.
nodular intestinal worm disease
nodular liver regeneration
nodules covering the surface of the liver in patients subjected to persistent or repetitive poisoning, usually by poisonous plants.
nodular lungworm

nodular necrobiosis
multiple, cutaneous nodules of unknown etiology on the neck, withers and back of the horse. They are composed of degenerate collagen and an eosinophilic and granulomatous response. Called also equine nodular collagenolytic granuloma or eosinophilic granuloma.
