title: Cellular Neurothekeoma in a Female with Guillain-Barré Syndrome: A Case Report and Review of the Literature.
abstract: Cellular neurothekeoma is a rare cutaneous tumor that occurs more frequently in women. A 68-year-old female with a history of left nasal alar basal cell carcinoma and Guillain-Barré syndrome presented to the clinic with a 3-mm firm skin-colored papule with scattered telangiectasias. Histopathologic examination with immunochemistry of the lesion was consistent with cellular neurothekeoma. It stained positive for microphthalmia transcription factor and NKI-C3 and negative for HMB-45 and S-100. The lesion was excised with 3-mm margins, and no recurrence was noted within 1 year of follow-up. We present a case of cellular neurothekeoma in a patient with a history of Guillain-Barré syndrome as well as a review of the literature. Our case report is unique in that no prior association has been found in the literature between cellular neurothekeoma and Guillain-Barré syndrome.
