A Case of Eccrine Carcinoma with Lung Metastasis / 대한피부과학회지

ABSTRACT

Eccrine carcinoma does not have a characteristic clinical appreranc, but does have a high incidence of metastatic spread. It may arise anywhere in the skin. The microscopic patterns that of an adenocarcinoma, which may be confused with metastatic adenocarcinoma. In the classical type the histologic features varies from fairy well-differentiated tubular structures in some areaslo anaplastic carcinoma in other areas. The patient was a 51-year-old man who showed a painful, tender, right red-calored, 4 x 5crn-sized tumor mass on the right angle of the lower lip for ten years. In the diological examinations multiple metastatic foci were seen on both lung fields, Histopathologic findings of the skin and lung biopsy specimens revealed that of the classic type of eccrine carcinoma like the bove descriptions. Immunocytochemical studies showed a positive reactivity to anti-cytokeratin anti-ibody, anti-CEA antibody, and anti-S-100 protein on the skin and lung biopsy specimens and no he reactivity to anti-S-100 protein on the lung mass. Electronrnicroscopic findings revealed eccrine glaidlar structures such as nunierous mitochondria and dense core granules in the cytoplasm of neoplastic cells. We report a case of eccririe carcinoma with lung metastases baed on the clinical, radiological and histologic findings.
