Eosinophilic angiocentric fibrosis is a rare fibro-inflammatory disorder of unknown etiology with only 40 cases reported in the literature. It primarily affects the sinonasal tract and more rarely the orbit, the larynx and the gums. This benign disorder is characterized by a slowly progressive process mimicking a tumor, with frequent recurrences after surgical excision and cortico-therapy. The typical histology consists of fibro-inflammatory lesion with numerous eosinophils, arranged in a perivascular pattern. As the lesion matures, inflammation becomes less intense and the fibrosis progresses with an onion-skin type perivascular fibrosis. A recent paper suggests that EAF is part of the spectrum of IgG4-related systemic disease. We report a case of orbital EAF in an 86-year-old woman which sustained this hypothesis.

We report the first case of an unusual sarcoidosic muscular involvement, complicated with radial nerve palsy. A 58-year-old woman suffering from a mediastinopulmonary sarcoidosis, was admitted for a driving deficit of the hands with a radially deviation during the wrist extension. She had been given a diagnosis of motor branch radial nerve entrapment syndrome. The patient had neurolysis with many muscle biopsies compatible with multiples sarcoidosic nodules, especially at the level of supinator muscle at the origin of the radial nerve compression.
