INTRODUCTION Cutaneous eccrine porocarcinomas are uncommon malignant tumors of the sweat gland. CASE PRESENTATION A 76-year-old Caucasian man presented to our hospital with a left temporal mass. We describe a case of eccrine porocarcinoma with metastasis to the parotid gland with special emphasis on the role of surgical resection and adjuvant radiation therapy. CONCLUSION Besides surgical r...

BACKGROUND Eccrine porocarcinoma is a rare malignant tumor of the sweat gland, characterized by a broad spectrum of clinicopathologic presentations. Surprisingly, unlike its benign counterpart eccrine poroma, eccrine porocarcinoma is seldom found in areas with a high density of eccrine sweat glands, like the palms or soles. Instead, eccrine porocarcinoma frequently occurs on the lower extremiti...

Eccrine poromas and porocarcinomas are adnexal tumors derived from the sweat duct epithelium. However, eccrine poroma is benign in nature, whilst eccrine porocarcinoma is regarded as its malignant counterpart. We report the case of a man who presented simultaneously with an eccrine poroma and eccrine porocarcinoma. Both lesions had no clear distinctive features, enhancing the need of high-level...

eccrine porocarcinoma is a rare malignant adnexal tumor of ductal portion of eccrine sweat gland. it occurs commonly in the lower extremities and rarely in scalp, face, ear, trunk and upper extremities. this survey presents a classic case of eccrine porocarcinoma of scalp in a 58 yr old male patient, presenting as cauliflower like growth over parietal aspect of scalp.

Apocrine-eccrine carcinomas are rare and associated with poor prognosis. Currently there is no uniform treatment guideline. Chemotherapeutic drugs that selectively target cancer-promoting pathways may complement conventional therapeutic approaches. However, studies on genetic alterations and EGFR and Her2 status of apocrine-eccrine carcinomas are few in number. In addition, hormonal studies hav...

BACKGROUND Increasing evidences support the role of Merkel cell polyomavirus (MCPyV) and human papillomavirus (HPV) in non-cutaneous and cutaneous tumours. Porocarcinoma is a rare malignant neoplasm that arises from the intraepidermal ductal portion of the eccrine sweat glands. The aetiology of porocarcinoma is largely unknown and no systematic studies have been done to investigate the implicat...

KIT (CD117, c-kit) is a receptor tyrosine kinase involved in the tumorigenesis of several neoplasms. KIT is expressed by the secretory cells of normal sweat glands. We studied the KIT expression and KIT mutational status in various benign and malignant tumors of eccrine and apocrine glands. We included a total of 108 cases comprising 10 benign and 6 malignant sweat gland tumors, and KIT express...

Eccrine poroma is a benign adnexal tumour of the uppermost portion of the intraepidermal eccrine sweat gland duct and acrosyringium. Eccrine porocarcinoma is the malignant phenotype arising from the intraepidermal portion of the eccrine sweat gland duct epithelium or from pre-existing eccrine poroma. Both commonly occur in the palms or sides of the feet; these areas have a high concentration of...

Eccrine poroma is a benign neoplasm thought to originate from the eccrine sweat glands. The majority of eccrine poroma occur on the hairless acral surface, and cases of eccrine poroma on the scalp are rare. Moreover, all these case reports describe only the histopathological, not radiological, features of eccrine poroma. Here, we first report the magnetic resonance (MR) findings in a rare case ...
