A 24-year-old woman was seen in consultation for a painless tumor of 6 cm in diameter of the vulva. The excised oval tumor was situated in the lower part of the dermis and encapsulated (〈link href="#f1"〉Fig. 1A). It was completely composed of multiple adjacent cell complexes, each containing 5–20 laminar cells and resembling Wagner–Meissner touch corpuscles (〈link href="#f1"〉Fig 1B and 1C). The nuclei of the laminar cells were located at the periphery of the corpuscles or were arranged transversely to the long axis of these structures along the lamellae. The nuclei were oval or showed one or several nuclear invaginations. Mitoses were not observed. These corpuscles showed a positive immunohistochemical reaction for S-100 (〈link href="#f1"〉Fig. 1D), vimentin, and neuron-specific endase (NSE) (not shown), but were negative for CD-68, desmin, and α-actin. The gross and microscopic morphology and the immunohistochemical findings were compatible with a diagnosis of Wagner–Meissner neurilemmoma of the vulva. The patient remained disease free for 2 years after surgery.〈figure xml:id="f1"〉1〈mediaResource alt="image" href="urn:x-wiley:00119059:IJD1756_1:IJD_1756_f1"/〉(A) Gross appearance of the excised oval tumor of the vulva, situated in the lower part of the dermis and encapsulated.
