Nodular fasciitis

ALK-1 may be seen In leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma, but is negative in nodular fasciitis, desmoid tumor, infantile myofibroma-tosis, and infantile fibrosarcoma.

Diffuse fasciitis with eosinophilia (a variant of scleroderma) (42), reversible nodular cutaneous pseudoljm-phoma, acromelanosis (43), hypertrophic retroauricular folds, and severe forms of erythema multiforme (Stevens-Johnson sjmdrome and toxic epidermal necrolysis) (44,45) are all rare (SED-13, 144) (SEDA-22, 90) (33). 

Plantar fascia tears are located at the posterior insertion of the fascia. This condition is most often observed in sportsmen who have sustained forceful plantar flexions. The US appearance of plantar fascia rupture is similar to that of plantar fasciitis and the diagnosis relies mainly on clinical and US findings, including focal nodular swelling and a hypoechoic appearance of the fascia (Fig. 17.33e,f). Surgical fasciotomy exhibits similar characteristics (Yu et al. 1999 Yu 2000). The fascia remains markedly thickened with indistinct superficial and deep margins, probably representing perifascial fibrosis (Fig. 17.35).
