Apocrine adenomyoepithelioma--a rare but distinctive primary sweat gland neoplasm.

abstract：:Recently, T-cell lymphoma localized to the subcutaneous tissue has been reported. We report the clinical, histologic, immunohistochemical, and molecular genetic findings in 6 patients who we believe had this peculiar T-cell lymphoma with its unique morphologic and clinical features. All patients presented with deep-se...
