Background . Subcutaneous ependymomas have been reported rarely in dermatologic reviews and, apparently, were never associated with other cutaneous malformations. Methods . A 60‐year‐old woman with a retrolumbar subcutaneous ependymoma and a giant bathing‐trunk nevocellular nevus submitted to thorough dermatologic and neurologic investigation. The surgical material was extensively analyzed with light and electron microscope. The literature was reviewed. Results . The tumor fits exactly the classical prerequisites of the clinical and pathologic diagnosis. In contrast with the literature, it developed at 53 years, apparently after a trauma, within a congenital giant nevocellular nevus, at the retrolumbar level; it proved unrelated to any spinal cord alteration and so far appeared quite benign. Conclusions . The observation of a retrolumbar subcutaneous ependymoma is reported with detail; this tumor exceptionally recognized by dermatologists must be included in the differential diagnosis of lumps arising in the retro‐lumbar‐retrosacral area. The most peculiar feature was its development within a giant bathing‐trunk nevocellular nevus; such a fascinating association of two neurectodermal defects, as far as known, is presented for the first time.
