Underarm or groin freckles

Underarm or groin freckles are small, flat, brown spots that can appear in the underarm or groin area. They usually develop over time and can range in size from a few millimeters to a few centimeters. They may be light or dark brown in color and can have either a smooth or rough texture. They may also be accompanied by itching, burning, or tenderness. In some cases, they may be a sign of an underlying condition such as an infection or skin disorder.
