[A case of nodular pseudosarcomatous fasciitis treated with "presuture" technique].

This paper reviews a case of nodular (pseudosarcomatous) fasciitis. It consists of a rare benign lesion of the soft tissues. The rapidity of its growth and the cellular features represent a diagnostic challenge when compared with that of a sarcoma. The patient, a 36 year old female, 20 days before surgical treatment, noticed the growth of a nodular lesion on the left forearm skin. After echotomography and ultrasound guided needle biopsy diagnosis of nodular pseudosarcomatous fasciitis was established and the patient underwent surgical treatment. The nodular lesion, noncapsulated, (diameter 2.5 x 1.2 cm) greyish-white colored, with slimy consistency, and myxoid character, was microscopically composed by atypical fibroblasts, with myxoid ground substance. The nodular lesion was removed using the "pressure" technique by Serge Baux of Rothschild Hospital in Paris using two Kirschner threads pulling the skin surrounding the biopsy wound. By this technique was possible to achieve a rapid skin expansion. The nodular pseudosarcomatous fasciitis remains a very difficult lesion to recognise unless the aid of a biopsy.
