Introduction: Tinea corporis and tinea cruris are skin infections caused by dermatophyte fungus and may be characterized by the serpiginous plaque with scales along the edges of an active erythematous lesion accompanied by central healing in the center of the lesion. Blood type is thought to play a role in the incidence of tinea corporis and tinea cruris disease and can affect the disease becomes chronic. This study aims to determine the relationship between ABO blood group typing with tinea corporis and or tinea cruris. Methods: Study design using cross-sectional analytic study which involved 68 patients who suspected tinea corporis and or tinea cruris. We did 10% potassium hydroxide examination of skin scrapping, cultured of dermatophyte, collected blood sampling and checked for ABO blood group typing to all subjects. Chi-square analysis is used to evaluate the relationship between tinea corporis and cruris with ABO blood type. Results: In this research, most of the sexes were male (45,6%), most of the ages were 26-35 years old (38,2%), the highest level of education were junior high school and college (25% and 25%), the highest duration of disease was chronic (72,1%), the highest result of 10% potassium hydroxide examination was negative (52.9%), most of fungal culture result was no dermatophyte fungus growth (73.5%), and the highest incindence of tinea corporis and or tinea cruris belonged to blood group A (27.9%). Statistically, there was significant relationship between blood group with tinea corporis and or tinea cruris (p= 0.000), there was significant relationship between blood group with tinea corporis and or tinea cruris based on 10% potassium hydroxide examination (p = 0.000), and cultured of dermatophyte (p = 0.000), but there was no significant relationship between blood type with duration of disease (p = 0.634). Conclusion: There was significant relationship between blood group with tinea corporis and or tinea cruris.
