Benign dermal Schwannoma with glandular elements-true heterology or a local 'organizer' effect?

A unique case of intradermal Schwannoma containing five morphologically distinct types of gland, which had arisen in the forearm of a 16‐year‐ald girl, is presented. The glandular elements have been investigated both histochemically and immunohistochemically. While some of these structures probably represent entrapped dermal appendages, it is argued that this tumour shows true heterologous glandular differentiation and, as such, is the second convincing reported example of benign glandular Schwannoma which has been reported. The literature with regard to glandular Schwarmomas is also reviewed.
