title: Sweat gland tumor with glandular and spindle cell features.
abstract: We studied a sweat gland tumor by light and electron microscopy that displayed both well-differentiated glandular areas and an anaplastic spindle cell component suggestive of neuroendocrine differentiation. The Merkel cell or a primitive pleuropotential cell is considered to be the most likely cell of origin for this tumor.
