Ankle neurothekeoma: A case report
2013, Journal of Foot and Ankle SurgeryCitation Excerpt :It thus was suggested that the type of neurothekeoma should be determined from the immunohistochemical expression rather than the morphologic aspects. Because cellular neurothekeoma has greatly variable and inconsistent staining patterns, some have postulated that the myxoid type is the end stage of cellular neurothekeoma (10). To date, no consensus has been reached on whether neurothekeomas derive from Schwann cells, perineural cells, or fibroblasts (11).
Neurothekeoma of the median nerve: Case report
2012, Journal of Hand SurgeryCitation Excerpt :Longer follow-up periods are necessary before definitive conclusions can be reached regarding the potential for malignant transformation. Barnhill et al6 presented clinical, light microscopic, immunohistochemical, and ultrastructural observations on 11 cases of neurothekeoma. They classified 8 cases as cellular neurothekeoma and 3 as myxomatous neurothekeoma.

2008, Journal of Plastic, Reconstructive and Aesthetic SurgeryCitation Excerpt :Cellular neurothekeomas (CNT) generally present more of a diagnostic challenge in that they bare resemblance to other dermal tumours, notably melanocytic lesions, and lack distinct immunophenotype.1,4,10 S-100 expression is usually absent and helps to exclude a melanocytic lesion – an important differential to exclude and hence prevent overly aggressive treatment of a CNT.4 Histology of the reported tumour differed from a CNT in that it showed prominent features of cellular atypia and mitotic activity, thus raising concerns regarding malignant potential.
