Tehran University of Medical Sciences Acta Medica Iranica 0044-6025 39 4 2001 12 15 222 225 Hashemi HM 2015 09 28 A case of pleomorphic adenoma in sweat gland is reported here. The histopathologic report confirmed the diagnosis. Pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. Pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. Upon closer examination, the tumor contained areas of apocrine decapitation secretory activity , and primitive hair follicles indicating cutaneous rather than mucosal origin. One year follow-up examination has revealed no evidence of recurrence. https://acta.tums.ac.ir/index.php/acta/article/view/2481 https://acta.tums.ac.ir/index.php/acta/article/download/2481/2469
