Dermatopathic lymphadenopathy is a distinctive form of paracortical lymph node hyperplasia that usually occurs in the setting of chronic dermatologic disorders. The aim of this study is to update our understanding of the clinicopathologic and immunophenotypic features of dermatopathic lymphadenopathy. The study cohort was 50 lymph node samples from 42 patients diagnosed with dermatopathic lymphadenopathy. The patients included 29 women and 13 men with a median age of 49 years (range, 12-79). Twenty-two (52%) patients had a dermatologic disorder, including mycosis fungoides (n = 6), chronic inflammatory dermatoses (n = 13), melanoma (n = 1), squamous cell carcinoma (n = 1), and Kaposi sarcoma in the context of human immunodeficiency virus infection (n = 1). Twenty (48%) patients did not have dermatologic manifestations. Lymph node biopsy specimens were axillary (n = 22), inguinal (n = 21), cervical (n = 4), and intramammary (n = 3). All lymph nodes showed paracortical areas expanded by lymphocytes; dendritic cells, including interdigitating dendritic cells and Langerhans cells; and macrophages. Melanophages were detected in 48 (98%) lymph nodes. Immunohistochemical analysis provided results that are somewhat different from those previously reported in the literature. In the paracortical areas of lymph node, S100 protein was expressed in virtually all dendritic cells, and CD1a was expressed in a significantly greater percentage of cells than langerin (80 vs. 35%, p < 0.0001). These results suggest that the paracortical regions of dermatopathic lymphadenopathy harbor at least three immunophenotypic subsets of dendritic cells: Langerhans cells (S100⁺, CD1a^+(high), langerin⁺), interdigitating dendritic cells (S100⁺, CD1a^+(low), langerin^-), and a third (S100⁺, CD1a^-, langerin^-) minor population of dendritic cells. Furthermore, in more than 60% of dermatopathic lymph nodes, langerin highlighted trabecular and medullary sinuses and cords, showing a linear and reticular staining pattern, which could be a pitfall in the differential diagnosis with Langerhans cell histiocytosis involving lymph nodes.
