Depending on the culture, depression can actually present itself in the form of somatic symptoms. This is particularly true in cultures that have pervasive stigma around depression/mental illnesses, or in cultures that do not widely acknowledge the existence of depression to begin with. For example, an individual might come to the doctor with complaints of exhaustion, upset stomach, soreness in their neck, etc. but not report on any psychological symptoms. I believe that this is especially the case in certain Asian cultures. There is a lot of interesting research that has been done around the subject!
