Linear IgA bullous dermatosis (LABD) in adults is characterized by sub
epidermal bullae associated with a linear deposition of IgA at the bas
ement membrane zone. Its cause is unclear, although it appears to have
an immune-mediated basis. The development of LABD in a cancer patient
undergoing immunotherapy has been described in the French literature.
We describe a similar case of LABD arising in a patient while undergo
ing interleukin-2 immunotherapy for renal cell carcinoma.
