Lymphoepithelioma-like carcinoma and simultaneous marginal zone lymphoma of the skin: a case report

Am J Dermatopathol. 2014 Feb;36(2):e26-9. doi: 10.1097/DAD.0b013e318297caef.

Abstract

Lymphoepithelioma-like carcinoma (LELC) of the skin is a rare malignant epithelial neoplasm, which shows histological resemblance of nasopharyngeal carcinoma (Schmincke-Regaud tumor). Similar tumors have been reported at a variety of sites, including salivary gland, tonsil, thymus, stomach, and uterus. Extracutaneous LELC shows frequently an association with Epstein-Barr virus, whereas Epstein-Barr virus in LELC of the skin has been described only once till now. LELC of the skin usually presents as a papulonodular lesion on the head or neck of patients above 50 years of age. Here, we describe a collision tumor with an LELC and a marginal zone lymphoma of the skin in a 75-year-old female patient. To our knowledge, this is the first reported case of an association between these 2 malignancies, and the possibility of a causal relationship is discussed.
