Giant vascular eccrine spiradenomas (GVESs) are a rare variant of the eccrine spiradenoma that develops from the sweat gland. It is different from the eccrine spiradenoma in its larger size and greater degree of vascularity. Bleeding and/or ulceration are common clinical features of this tumor, and are the reason why it is often clinically confused with a vascular or malignant tumor. Here, a rare case of GVES without bleeding or ulceration is reported.

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.

BACKGROUND: The positive reactions of carcinoembryonic antigen(CEA) show varying degrees in the tissue of all sweat gland neoplasms by immunohistochemistry. The CEA secreted from sweat glands presents a high value, compared with that of serum. OBJECTIVE: The study was to evaluate the sweat CEA value in relation to serum CEA value by sex, smoking status and blood type in healthy subjects. METHOD: Fifty-two healthy subjects(M : 43, F :9) aged 21-30, participated in the study. 2ml sweat was collected from the face and chest after intense exercises and 3ml blood was collected from their antecubital veins. Roche Core CEA enzyme immunoassay was used for the measurement of sweat and serum CEA. RESULTS: Sweat CEA values were 102.0+4100.5ng/ml in males and 70.6+458.5ng/ml in females, with their mean valueof 96.6+/-94.9ng/ml. Sweat CEA values were 108.3+/-103.5ng/ml in 27 smokers and 83.9+/-84.8ng/ml in 25 nonsmokers(p>0.05, t-test). Sweat CEA values were higher among the males and the smokers. Serum CEA values were 2.5+/-1.7ng/ml in males and 1.6+/-0.8ng/ml in females, with its mean value of 2.4+/-1.6ng/ml. There was no difference between serum values of smokers and nonsmokers. Sweat CEA values were about 40 times higher than those of serum, with no correlation of sweat and serum CEA(correlation coefficient=-0.16, P>0.05). In the blood type study, sweat CEA values were 123.1+/-131.8ng/ml in A type and 66.1+/-55.0ng/ml in B type(P>0.05), whereas serum CEA values were higher in AB type and lower in O type(P<0.05, ANOVA). CONCLUSION: Sweat CEA values are extraordinarily high in contradistinction to serum. Sweat CEA values are not affected by sex, smoking status and blood type. There seems to be no association between CEA values of sweat and serum.

Primary epithelial-myoepithelial carcinoma (EMC) of the lung is an extremely rare neoplasm that originates from submucosal bronchial glands and has been found in the salivary glands, breast tissue, and sweat glands. However, only a few cases in the respiratory tract have been identified. In the literature, most pulmonary EMCs have been reported to have developed endobronchially although a few EMC cases have been presented as intraparenchymatous tumors. We have identified a case of primary EMC that developed in the peripheral lung parenchyma.

Clear cell hidradenoma is an uncommon benign skin appendageal tumor that typically involves the dermal layer of the head, face, and extremities. The breast is a rare site for this lesion, with only two documented cases, which were determined based on mammogram and sonogram findings. We present a case of clear cell hidradenoma of the axillary tail with radiological findings and a literature review.
