Vascular leiomyoma and geniculate ganglion.

Magliulo G, Iannella G, Valente M, Greco A, Ciniglio Appiani M - J Neurol Surg Rep (2013)

Bottom Line: Participants A 45-year-old man with a grade III facial paralysis according to the House-Brackmann scale of evaluation.Postoperative histology and immunohistochemical studies revealed features indicative of solid vascular leiomyoma.Optimal postoperative facial function is possible only by preserving the anatomical and functional integrity of the facial nerve.

ABSTRACT
Objectives Discussion of a rare case of angioleiomyoma involving the geniculate ganglion and the intratemporal facial nerve segment and its surgical treatment. Design Case report. Setting Presence of an expansive lesion englobing the geniculate ganglion without any lesion to the cerebellopontine angle. Participants A 45-year-old man with a grade III facial paralysis according to the House-Brackmann scale of evaluation. Main Outcomes Measure Surgical pathology, radiologic appearance, histological features, and postoperative facial function. Results Removal of the entire lesion was achieved, preserving the anatomic integrity of the nerve; no nerve graft was necessary. Postoperative histology and immunohistochemical studies revealed features indicative of solid vascular leiomyoma. Conclusion Angioleiomyoma should be considered in the differential diagnosis of geniculate ganglion lesions. Optimal postoperative facial function is possible only by preserving the anatomical and functional integrity of the facial nerve.

FI120059-4: Geniculate ganglion tumor; the arrowheads indicate the presence of cells with elongated nucleus, eosinophilic cytoplasm organized in small bundles; positivity for smooth muscle actin (Immunohistochemical, 10 ×).

Mentions: Postoperative histology showed cells of medium size with an elongated nucleus and irregular eosinophilic cytoplasm, organized in small bundles. In the context of this lesion, numerous vascular spaces were evident with flat endothelium that were compressed by the lesion. Immunohistochemical studies showed abundant positivity of tumor cells for smooth muscle actin and negativity for S100. These aspects were indicative of solid VL (Fig. 4).
