AbstractIn Parthenium dermatitis, photosensitivity is a common feature. We studied the minimal erythema dose to UVA (2-18J/cm2) and UVB (30-70mj/cm2). MED to UVB was lowered in 9 cases but not detected in 1 whilst MED to UVA was seen in only 1 case. Reduction of MED to UVB is a definite indicator of photosensitivity in Parthenium dermatitis.
