This is an exceedingly difficult case and it is not really possible to come to a diagnosis on the basis of this one image. I included it to make you all aware of the various morphologies that tumors may have. This is in fact a metastasis from a clear cell sarcoma which Alex Lazar kindly shared with me. Although much of the tumor showed the features as seen in this field, there were areas of clear cell change and focal melanin pigment was present. I can very easily see how some of you thought of a hidradenoma. Phillip

Tough one... I think I favour an eccrine spiradenoma though.

I think I am seeing a polymoprphic lymphoid infiltrate, some plasma cells, few esinophils and may be some histiocytes. Admixed with the infiltrate, I think there are capillaries that look hyalinized or surrounded with esinophilic hyaline material. I am thinking of angioimmunoblastic lymphadenopathy. Less likely another case of hyaline vascular variant of Castleman's disease. The other possibility is that I am totally wrong and this might be as Dr Carr said an Esoteric Confusing Odd Mesmerising Entity!!!!!!!!!
