P. Chalem et al., Porphyria cutanea tarda affecting a rheumatoid arthritis patient treated with methotrexate: association or coincidence?, RHEUMATOLOG, 38(5), 1999, pp. 453-456
We describe the case of a 44-yr-old woman, suffering from rheumatoid arthri
tis for 15 yr, who developed porphyria cutanea tarda while being treated wi
th methotrexate. The cutaneous lesions healed and the metabolic anomalies i
mproved after a few months, despite continuing the treatment.
