J Am Acad Dermatol. 2006 May;54(5):745-62; quiz 763-6. doi: 10.1016/j.jaad.2004.06.051.


Paraneoplastic dermatoses comprise a heterogeneous group of noninherited skin conditions that manifest internal malignancy. Familiarity with paraneoplastic dermatoses is important to both clinician and pathologist alike, as recognition of such a condition offers opportunity for early diagnosis and treatment of internal malignancy; monitoring for tumor recurrence; and insight into pathophysiology which may yield possible clues to treatment. Herein are reviewed 16 of the best established paraneoplastic dermatoses that display distinctive clinical and pathologic findings.

Learning objective: At the conclusion of this leaning activity, participants should be able to recognize, diagnose, and describe the clinical and pathologic findings of paraneoplastic dermatoses.
