摘要:
A case of painful eccrine angiomatous hamartoma of the wrist in a 10-year-old girl is presented. It was located in the reticular dermis and contained abnormal tubules resembling eccrine secretory coils and thin vascular channels dispersed in the collagenous tissue of the dermis. Some eccrine ducts showed dilatation. The noteworthy features of this case were the absence of hyperhidrosis over the lesion, and the presence of focal neural infiltration by the tubular structures. Electron microscopy showed mostly clear cells and occasional dark cells lining the tubular structures. This case supports the theory of abnormal induction of heterotypic dependency with resultant malformation of adnexal as well as mesenchymal elements.
