Pityriasis rosea-like eruptions due to mustard oil application

Indian J Dermatol Venereol Leprol. Jul-Aug 2005;71(4):282-4. doi: 10.4103/0378-6323.16625.


A young man employed in a construction company, presented with cutaneous lesions clinically simulating pityriasis rosea. Satisfactory and complete response to corticosteroids and antihistamines was followed by recurrence. Multiple recurrences within a short span of time arose a suspicion of alternative diagnosis. Site visit helped us to rule out occupational contact dermatitis. Further history taking revealed that he was recently using mustard oil for body massage. Subsequent patch testing confirmed contact hypersensitivity to mustard oil. Avoidance of the contact with mustard oil arrested appearance of further skin lesions. We stress the importance of taking a good history in clinical practice in disclosing a possible contactant.
