@entity28045 of Gallager and Helwig ( XXXX variant): report of a case with electron microscopic and immunohistochemical studies.

@entity1 @entity2610 @entity28045 @entity5
A @entity1 presented with a frontal nodule of the scalp. Histopathological examination revealed a myxomatous multilobulate @entity5 composed of epithelioid cells with variable pleomorphism. Perineurium-like structures were seen but only around isolated lobules located at the @entity5 periphery. Electron microscopy revealed polygonal cells and cells with elongated cytoplasmic processes. Many cells had myelinoid figures. A basement membrane-like lamina was noted around some cells. Some of the @entity5 cells were immunoreactive for @entity2610 . This finding suggests that the @entity5 cells are of schwannian type. @entity28045 of Gallager and Helwig is a rare, probably @entity5 with fairly distinctive histopathologic characteristics. It appears to be a variant of @entity28045 .
