ABSTRACT
The cutaneous lymphadenoma is a recently described tumor with a distinctive histologic picture representing a basaloid epithelial proliferation and intraepithelial lymphocytic infiltration; it seems to be a benign adnexal neoplasm of uncertain histogenesis. We documented one example of cutaneous lymphadenoma showing typical histologic features. The tumor typically presented as a well circumscribed nodule with scant or no epidermal connections. The proliferating one consisted of multiple rounded lobules of basaloid cells with some degree of peripheral palisading. There was an intense infiltrate of small lymphocytes within the lobules but few in the stroma. No clear adnexal differentiation is noted. Immunohistochemically, the basaloid cells show weak immunoreactivity for high molecular weight keratin and carcinoembryonic antigen, small lymphocytes for T-cell marker and some dendritic cells for S-100 protein. After surgical resection, we found no evidence of local recurrence or distant metastasis for four years, so we considered this tumor as a benign one and diagnosed as cutaneous lymphadenoma by typical histologic features.
