Metastatic eccrine carcinoma with stomach and pericardial involvement

Skin adnexal tumors (SAT) are rare tumors that make up about 1%-2% of all cutaneous malignancies. ey represent a various group of benign and malignant tumors that arise from skin adnexal epithelial structures: hair follicle, pilosebaceous unit, and apocrine or eccrine sweat glands. Although this derivation provides a practical basis for classi€cation, some tumors may exhibit a mixed or more than one line of di‚erentiation, rendering precise classi€cation of those neoplasms diƒcult, and such cases should be categorized according to prevailing phenotype. In this report, we present a patient with metastatic eccrine carcinoma. Clinical experience for metastatic disease treatment is derived from a few reports, and there are no universal treatment guidelines. Given the few reported cases and the absence of randomized clinical trials for these patients, it is important to collect clinical experiences.
