Despite their variable etiopathologies, all forms of dermatitisThis glossary term has not yet been described. show similar histopathologic just as similar dermoscopic characteristics. Dermatitis usually exhibits red dots in a patchy distribution and yellow scales. The red dots are identical to the vesselsThis glossary term has not yet been described. in psoriatic lesions, but unlike psoriasisThis glossary term has not yet been described., their distribution is not homogenous and regular, but rather clustered, generating an irregular, “patchy” pattern.SuperficialThis glossary term has not yet been described. scaling is a frequent characteristic of dermatitis, but opposed to psoriasis and other erythematosquamous skin diseases, the scales in dermoscopy of dermatitis reveal a yellow colorColor (American English) or colour (Commonwealth English) is the characteristic of human visual perception described through color categories, with names such as red, yellow, purple, or blue. either alone, or in combination with white.  Belonging to the group of the characteristic yellow scales, the “yellow clod sign” is frequently observed in nummular eczema. Notably, yellow scale color is dermoscopically detected not only in acute, but also in chronic dermatitis. Contact dermatitis, nummular eczema, generalized dermatitis, chronic dermatitis, seborrheic dermatitis and other subtypes were reported to reveal similar findings in dermoscopy, but further investigation on their specific pattern is needed.
