Über das eingekapselte intraneurale granuläre Neurom (Feyrter)

Abstract

Two cutaneously and subcutaneously localized nodules of the left mamma from a 66-year-old patient were excised. The lesions were flesh-colored, firm and well circumscribed. Sections of the tumors show the typical aspects of granular cell tumor. The lesions were both surrounded by a condensation of fibrous tissue which formed a capsule. This condensation of fibrous tissue resembled and on some sections was in continuity with the perineurium of a nerve. In addition to that is the finding of granular cells situated within a nerve fascicle and apparently replacing several, or all, of the nerve fibres.
