The Contact Dermatitis Clinic evaluates and investigates patients who present with dermatitis that may have a suspected exogenous cause. Special investigations, like patch testing and prick testing, are performed in this clinic.

The Joint Occupational Dermatoses Clinic manages patients where the cause of exogenous dermatitis is thought to be occupationally related. It is a collaboration between the National Skin Centre and the Occupational Health Department, Ministry of Manpower. It convenes fortnightly and screens through patients from both the General Clinics of National Skin Centre and referrals from occupational physicians or private practitioners. Specific recommendations for the patients are made after complete evaluation and investigation at the clinic. Investigation includes patch testing, prick testing and sometimes, factory visits.
