Agminated cellular neurothekeoma

Abstract

Cellular neurothekeoma represents a benign, slow-growing neoplasm that typically occurs as a solitary lesion on the face, neck or arm. Reports of multiple lesions are rare. To our knowledge, multiple lesions occurring as eruptive clusters localized to a single anatomical site has not been previously reported. This report details a case of an agminated cellular neurothekeoma occurring on the nose of a 28-year-old man. Recognition of multiple localized eruptive lesions of cellular neurothekeoma is important in order to facilitate correct diagnosis and avoid unnecessary treatment.

Immunohistochemical analysis of KBA.62 in 18 neurothekeomas: a potential marker for differentiating neurothekeoma, but a marker that may lead to confusion with melanocytic tumors

“…Neurothekeoma typically presents as a solitary lesion, however, there are case reports of multiple neurothekeomas . Multiple lesions suggest the potential role for an underlying genetic factor in lesion pathogenesis.…”
