An unusual case of glandular schwannoma.
Glandular differentiation is exceedingly rare in peripheral nerve sheath tumors. In this report, an exceptional case of retroperitoneal glandular schwannoma is described in which the glandular element is markedly atypical, whereas the schwannian component is benign by morphologic analysis. To the best of our knowledge, the biologic behavior for such a lesion is unknown because similar cases have not yet been described in the literature.
