BACKGROUND
Cellular neurothekeoma is a benign lesion most commonly found on the face and upper extremities in the first two decades of life.
METHODS
Retrospective clinicopathologic review of 12 examples of cellular neurothekeoma typified by prominent stromal sclerosis, a distinctive variant that we
The histogenesis of cutaneous nerve sheath myxoma (NSM)/cellular neurothekeoma (CNT) is still controversial. In this study, we examined the ultrastructural features of 16 NSM (3 classical, 11 CNT, and 2 mixed NSM/CNT). We classified the cells into 4 groups ultrastructurally. Type I cells were
A patient presented with a frontal nodule of the scalp. Histopathological examination revealed a myxomatous multilobulate tumor composed of epithelioid cells with variable pleomorphism. Perineurium-like structures were seen but only around isolated lobules located at the tumor periphery. Electron
We report a case of cellular neurothekeoma showing unusual immunohistochemical findings and occurring on the left upper arm of a healthy 48-year-old woman. She presented with a 1 cm, red, asymptomatic, dermal nodule of 1 year duration. A biopsy showed dermal proliferation of plexiform fascicles of
We describe the clinical, histopathologic, and immunohistochemical characteristics of five examples of a distinctive subtype of neurothekeoma we term "cellular neurothekeoma" (CNT). These lesions are nondescript papules or nodules primarily involving the head and neck areas of young adults.
An 11-month-old girl presented with an erythematous nodule on the chest, which had been growing for 8 months. The tumor was composed of uniform polygonal and spindle-shaped cells, forming nodules and fascicles. The diagnosis of neurothekeoma was based upon the histology and immunohistochemistry.
