Adult-onset recalcitrant eczema: a marker of noncutaneous lymphoma or leukemia.
BACKGROUND
Generalized eczema or erythroderma may be the presenting sign of cutaneous T-cell lymphoma. Additionally, intractable pruritus has been associated with Hodgkin's lymphoma. However, reports of adult-onset eczematous dermatitis has rarely been linked to noncutaneous lymphoproliferative disorders.


METHODS
We observed one patient in 1993 who had the onset of intractable dermatitis characterized by prurigo nodularis-like lesions and widespread erythematous plaques. After 18 months of cutaneous symptoms he experienced dyspnea. At this time Hodgkin's disease was diagnosed. This observation prompted us to evaluate subsequent patients with adult-onset eczema who were poorly responsive to therapy and in whom an obvious cause could not be determined. Over the next 24 months we identified an additional 2 patients with lymphoma who met this criteria.


CONCLUSIONS
Unexplained eczema of adult onset may be associated with an underlying lymphoproliferative malignancy. When a readily identifiable cause (eg, contactants, drugs, or atopy) is not found, a systematic evaluation should be pursued. Patients should be evaluated with a careful physical examination, complete blood cell counts, peripheral blood smears, chest roentgenography, computed tomography of the chest and abdomen, and serum protein electrophoresis.
