A 3-year-old boy presented with an unusual combination of indurated skin, sclerotic plaques with lichenification, and yellowish papules. Histopathology revealed diffuse dermal mucin deposits, and laboratory tests showed a positive throat culture for Group A streptococcus and elevated serum anti-streptolysin titers. An 10-day course of oral amoxicillin was associated with near-complete resolution of all dermatological findings within 4 months. This case represents a unique presentation of a self-resolving cutaneous mucinosis, likely associated with a streptococcal infection.
