Tubular apocrine adenoma and papillary eccrine adenoma are rare sweat gland neoplasms that appear as a small solitary lesion on the scalp or extremities, respectively. Although these lesions are thought to be distinct entities, there are enough similarities between them to group them under the term tubulopapillary hidradenoma or papillary tubular adenoma. We describe a case showing many tubular structures with papillary projection, syringocystadenoma-like structures, and eccrine hirocystoma-like structures in the axillary area. The term of papillary tubular adenoma or tubulopapillary hidradenoma may be prefered in this case.

Papillary eccrine adenoma is a rare benign sweat gland neoplasm. It occurs most often as a solitary nodule in women and is located predominantly on the distal portion of the extremities. This tumor is similar to tubular apocrine adenoma in histological and clinical aspects, so distinction of these tumors is still controversial. We report a case of two papillary eccrine adenomas developed on the left popliteal and calf area of a 58-year-old-man, this is the first report of the multiple papillary eccrine adenomas in Korea.

The papillary eccrine adenoma is a rare benign sweat gland neoplasm charscterized by potentislly locally aggressive clinical course. We report herein a case of papillsry eccrine adenoma in a 28-year-old female who presented single intradermal tumor on the right postauricular ares. Histopathological findings showed dilated ducts containing eosinophilic or keratinous materials and intraluminal papillary rowths.

Tumors occurring in the external auditory canal (EAC) are rare. In particular, tubular adenoma (TA) is an extremely rare sweat gland neoplasm occurring in the EAC and is generally considered as benign. Up to now, less than one hundred cases of TA have been reported in the English literature. In fact, a comprehensive review of literature shows that TA in the EAC has seldom been reported. Herein, we report a case of a 35-year-old man with TA that occured in the EAC, together with characteristic histopathological findings.

Biliary cystadenoma is a rare tumor that arises in the liver or, less frequently, in the extrahepatic ducts. Jaundice in patients with biliary cyst adenoma is not uncomon, but it is very rare that the jaundice is caused by tumor compression of the bile duct. A 43-year-old woman who had a huge biliary cystadenoma occupying the left liver developed deep jaundice. Endoscopic retrograde cholangiopancreatograpy demontrated that this tumor compressed the common hepatic ducts extrinsically which caused the deep jaundice.

40 patients diagnosed as cholangiome of which 9 patients diagnosed by biliary cell, 13 patients diagnosed by CT scanner, and 18 patients diagnosed by operation. The biliary obstruction in the general hepatic tube occurred in 95% of patients in which the lesion involved in the 2 branches of liver was 75%. The image of cholangiome in the film of cholangiography found that biliary fair stenosid (62,5%).

The papillary eccrine adenoma is a rare benign sweat gland neoplasm, first described by Rulon and Helwig in 1977. It is usually present as a solitary dermal nodule on the distal extremities. Histological examination revealed a well circumscribed, non capsulated dermal nodule consisting of multiple ducts with various size. These ducts were composed of double layered epithelial cells mostly and intraluminal papillation with eosinophilic luminal materials was seen. We report a case of papillary eccrine adenoma in 52-year-old male who presented single nodule on the right midback, uncommon area.
