Eccrine spiradenoma: A rare adnexal tumor.

Indian J Cancer 2017 Oct-Dec;54(4):695-696

Department of Pathology, 166 Military Hospital, Jammu, Jammu and Kashmir, India.

Eccrine spiradenoma is one of the rare adnexal tumors with eccrine differentiation; however, it is considered to have apocrine differentiation. Around 50 cases of eccrine spiradenoma have been reported in the literature. Due to vascularity and painful symptoms, it is often confused with the painful lesions of skin such as glomus tumor and angioleiomyoma. Read More

Surgical Neurology Branch, National Institute of Neurological Disorders and Stroke, National Institutes of Health.

Diagnosing and treating patients with persistent neuropathic pain associated with peripheral nerve lesions can be challenging. The authors report the rare case of a painful eccrine spiradenoma treated as a traumatic neuroma for many years because of a history of acute trauma, the presence of a tender palpable mass, and symptoms of allodynia. Surgical excision of the neoplasm completely relieved the pain and hypersensitivity that 2 prior surgeries and other nonsurgical treatments failed to resolve. Read More

J Cutan Pathol 2016 Nov 5;43(11):974-983. Epub 2016 Sep 5.

Department of Diagnostic Pathology, Kainan Hospital, Yatomi, Japan.

Background: This study was designed to evaluate the immunoexpression of DOG1, a specific marker expressed in gastrointestinal stromal tumors, in normal skin tissues and cutaneous epithelial tumors.

Methods: DOG1 immunostaining extent, intensity and pattern were evaluated in 69 cutaneous apocrine/eccrine tumors, 11 sebaceous tumors, 46 follicular tumors, 52 keratinocytic tumors and perilesional normal tissues.

Results: In normal tissues, DOG1 was expressed strongly in the intercellular canaliculi of eccrine glands, moderately in the myoepithelial cells of mammary and anogenital mammary-like glands, and weakly or not at all in the periphery of sebaceous lobules and the lower layer of epidermis and follicular infundibulum.

Brooke-Spiegler syndrome (BSS) is an inherited autosomal dominant disease characterized by the development of multiple adnexal cutaneous neoplasms most commonly spiradenoma, cylindroma, spiradenocylindroma, and trichoepithelioma. Multiple familial trichoepithelioma (MFT) is a phenotypic variant of the disease characterized by the development of numerous trichoepitheliomas (cribriform trichoblastoma) only. Malignant tumors arise in association with preexisting benign cutaneous neoplasms in about 5-10% of the patients . Read More

The intercellular bridges are essential structures in maintaining the histologic organization of the epithelium, while providing a very efficient way to exchange molecules between cells and transduction of the cell-to-cell and matrix-to-cell signals. Derangement in those important structures' physical integrity and/or function, which can be assessed by the presence or absence of several intercellular bridge proteins including claudin-4, E-cadherin, and β-catenin, was found to be related to several phenomena in the path to the neoplastic transformation. However, these proteins have not been studied in the wide variety of the skin neoplasms, in detail. Read More
