Psoriasis is a common inflammatory dermatosis that may be associated with a number of diseases. Recent studies provide evidence that there is a greater frequency of autoimmune diseases, but association with autoimmune connective tissue diseases is uncommon. The coexistence of psoriasis and lupus erythematosus is rare. Besides, the occurrence of morphea has rarely been reported in patients with lupus or psoriasis. We report a woman with cutaneous lupus and morphea profunda associated with psoriasis, with an excellent response to methotrexate, and review the literature.
