Unresponsive eczematous dermatitis: a case of pancreatic cancer masquerading as cutaneous T cell lymphoma

Abstract

Skin diseases may be the presenting sign of malignancy, but strict criteria are required to make the diagnosis of a paraneoplastic syndrome. Common dermatoses may also herald an underlying malignancy without meeting these criteria. We report the case of an elderly man with an unresponsive eczematous dermatitis whose evaluation eventually revealed a pancreatic carcinoma. This case is presented to alert the clinician that a common dermatosis may be the first sign of an occult malignancy, especially if it behaves in an atypical or aggressive manner or is recalcitrant to standard therapies.
