Originally considered muscle tumors, they have been identified as neural lesions, due to their close association with nerve and to their immunohystochemical characteristics.

• macrophagic myofasciitis
  21 December 2011

  A most unusual inflammatory myopathy, called "macrophagic myofasciitis", first described by the Groupe d’Etudes et Recherche sur les Maladies Musculaires Acquises et Dysimmunitaires (GERMMAD), a specific branch of the Association Française contre les Myopathies was recorded with an increasing frequency from 1993 in the main French myopathologic centers.
  In October 1999, 65 "macrophagic myofasciitis" cases were recorded since our first description.
