ABSTRACT

El linfadenoma cutáneo se caracteriza por ser una neoplasia intradérmica formada por lóbulos de células basalioides con empalizada periférica, con un estroma fibrocítico y un infiltrado linfoide prominente. Típicamente afecta a personas de edad media o avanzada y se localiza principalmente en la cara, como sucede con los 2 casos que presentamos. Creemos que, pese a su histogénesis controvertida, nuestros casos evidencian una clara diferenciación folicular Y una peculiar reacción inmunológica, con presencia de linfocitos T y células dendríticas dentro de los lóbulos, lo que ayuda a llevar a cabo el diagnóstico diferencial con neoplasias como el tricoblastoma, el tricoepitelioma desmoplásico, los carcinomas basocelulares o los siringomas (AU)


The cutaneous Iymphadenoma is a cutaneous neoplasm formed by lobes of basaloid cells, with peripheral palisading, with a fibrous stroma, and a prominent Iymphoid infiltrate. Typically it affects people of middle or advanced age and it is located mainly in the face. We think that in spite of their controversial histogenesis our cases show a clear follicular differentiation. These tumours show a peculiar immunologic reaction with the presence of T-Iymphocytes and dendritic cells inside the lobes which help us to carry out the differential diagnoses of neoplasms like the trichoblastoma, desmoplastic trichoepitheloma, basal cell carcinomas or syringomas (AU)
