Hello,
It can be due to erythrasma. Erythrasma is a chronic superficial infection of the folds of the skin and  the typical appearance is well-demarcated, brown-red macular patches. Wood lamp examination and gram staining are the tests for its diagnosis.

The standard therapy of erythrasma is antibiotics and antifungals because it is caused by a bacteria C minutissimum. Erythromycin is the drug of choice. Mild steroids are helpful in reducing the inflammation associated with it. But use it only after a dermatologist’s prescription. My sincere advice would be to consult a dermatologist.
Hope it helps. Take care and please do keep me posted on how you are doing. Kind regards.
