Dermatopathic lymphadenitis characteristically presents as a single or multiple enlarged axillary or inguinal lymph nodes. The lymph nodes are usually discrete, superficial, nontender, firm, and freely movable.1 Presentation as an enlarged neck mass is exceedingly rare. The disease is typically associated with a benign pruritic skin disorder. It is frequently noted as one of many findings in a systemic disease (eg, chronic lymphocytic leukemia or AIDS). It may also be associated with a cutaneous neoplasm (eg, mycosis fungoides or Sézary syndrome) or discovered as an isolated finding.
