Tubular apocrine adenoma (TAA) is a very rare sweat gland tumor. TAA and syringocystadenoma papilliferum (SCAP) rarely develop together in a nevus sebaceus (NS). Herein, we report on a 40-year-old Korean woman with TAA associated with SCAP that developed in a NS located on the scalp.

Clear cell hydroadenocarcinoma is a very rare sweat gland tumor. It has an aggressive course and high recurrence rate. Wide excision the first option in treatment of this tumor with rate metastasis. Subsequent radiotherapy chemotherapy are still controversial. In case, we presented patient who was operated on lipoma-like appearance scalp. The pathology result hidradenocarcinoma. We emphasized t...

The characteristic clinical and histological features of three cases of malignant eccrine poroma are discussed, in addition to the metastatic disease that had occurred in two cases. These cases were compared with previously reported cases of malignant eccrine poroma that had metastasised, and it is suggested that a strict classification of malignant eccrine sweat gland tumours should be made.

Trabecular carcinoma has been renamed as Merkel cell carcinoma because, ultrastructurally, tumour cells resemble Merkel cells of the skin. Recently, evidence of exocrine (sweat gland) differentiation in some trabecular carcinomas has been reported. These findings raise two possibilities: (1) trabecular carcinomas are a heterogeneous group of lesions; or (2) that trabecular carcinomas are glandu...

This issue features articles on the presence of specific “epigenetic” etiology associated with increased risk of developing comorbid dysexecutive and social anxiety symptoms in premutation women carrying the FMR1 gene and on fingolimod treatment andCSF neurofilament light chain levels in relapsing-remitting multiple sclerosis. Another featured article focuses on the factors influencing sweat gl...

Primary cutaneous mucinous adenocarcinoma is a rare sweat gland malignancy that most commonly occurs in the head and neck region. The histopathological similarities between primary cutaneous and metastasis from primary visceral tumors allow for both an interesting diagnostic dilemma as well as important management considerations with these patients.

UNLABELLED Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) have higher proliferation potency and lower immune resistance than human bone marrow MSCs and can differentiate into various functional cells. Many regulatory factors, including keratinocyte growth factor (KGF), are involved in the development of skin and cutaneous appendages. Although KGF is important in wound healing, t...

Attempts were made by Yen, and more successfully by Takahara (see 5, 6) to observe continuously the discharge of sweat from a single human sweat gland. A capillary glass tube was inserted into a sweat pore and the movement of the sweat column therein accumulated was recorded. This method is very difficult because the sweat duct runs through the epidermis in cork-screw fashion. Furthermore, the ...

Hidrocystomas, eccrine or apocrine, are rare ductal cystic benign lesions of sweat gland. They are mainly found on the head and neck region. These uncommon cystic lesions are extremely rare in external ear. We describe the second case in English literature of an eccrine hidrocystoma inside the external auditory canal and discuss its origin. Submitted : 12 August 2011 Accepted : 21 February 2012
