title: [Neuroectodermal tumors of the skin (a normative study)].
abstract: A group of bioptically examined neuroectodermal tumours of the skin and soft tissues consisting, in particular, of 170 Schwannomas and 350 tumours has been reevaluated in a retrospective study. The following common classification of these tumours has been recommended: I. Tumours of Schwann's cells: 1. neurilemmoma [A and B], 2. neurofibroma [with the following variants v. Recklinghausen's type, plexiform, pigmented, Paccinian, with Meissner-Wagner's bodies and meningiomatous], 3. amputation neuroma, 4. neurosarcoma, 5. others. II. Melanogenic tumours: A. pigmented naevi (junction, mixed, intradermal, epithelioid, clear cell, halo, neurocutaneous, fibrous, blue, proliferating blue, melanotic progonoma, others). -B. praecancerous melanosis. -C. malignant melanoblastoma (common type, from praecancerosis). III. Tumours of ganglion cells: 1. ganglioneuroma, 2. neuroblastoma, 3. paragangliomas (with granules, without granules, alveolar soft part sarcoma).
