RESUMO

Abstract: Cutaneous mucinoses are a complex and diverse group of connective tissue disorders characterized by the accumulation of mucin and/or glycosaminoglycan in the skin and adnexa. Cutaneous focal mucinosis appears as a solitary, asymptomatic, skin-colored to white papule, nodule, or plaque located anywhere on the body or in the oral cavity. It presents mainly in adults and is characterized on histopathology by mucin throughout the upper and mid dermis. We describe the dermoscopy of two cases of cutaneous focal mucinosis. Both lesions presented a nonspecific homogenous whitish pattern; the first case also exhibited a sharply demarcated yellow border.
