BACKGROUND: Lower legs and feet eczema may be due to exogenous causes such as allergic contact dermatitis (ACD) or endogenous cause such as atopy. Currently, patch testing is the only scientific proof of contact allergy. AIMS: The aim was to study the clinicodemographic profile and to evaluate the role of patch testing in lower leg and feet eczema. MATERIALS AND METHODS: This was a cross-sectional study conducted among 60 patients with lower leg and feet eczema. They were subjected to patch testing with Indian standard series and readings were interpreted according to the International Contact Dermatitis Research Group scoring system. RESULTS: Our study included 32 (53.3%) males and 28 (46.7%) females (M: F = 1.1:1). The mean age was 42.61 ± 13.40 years corresponding to occupationally active age group. Construction workers (10 [31.25%]) were the most common occupational group affected among males (P = 0.007). Among females, most commonly affected were housewives (10 [35.71%]) (P = 0.0002). The most common pattern of eczema seen was ACD (22 [36.7%]). Positive patch test response was recorded in 17 (28.3%) patients and the most common allergen found to be positive was potassium dichromate (6 [35.3%]). Correlating the morphology with patch test results, ACD (13 [59.1%]) was significantly positive when compared to other eczemas (4 [10.53%]) (P = 0.000). CONCLUSION: Patch testing is a valuable diagnostic aid in lower leg and feet eczema. It plays a pivotal role in identifying causative allergens associated with ACD from which allergen avoidance can be advised for a better clinical outcome and quality of life.
