Dermatitis: yellow scales and dotted vesselstiny pinpoint vessels



Dermatitis

Despite their variable etiopathologies, all forms of dermatitisalso known as eczema is a group of diseases that results in inflammation of the skin. show similar histopathologic just as similar dermoscopic characteristics. Dermatitis usually exhibits red dots in a patchy distribution and yellow scales.[1] 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.[1]

[1] Belonging to the group of the characteristic yellow scales, the “yellow clod sign” is frequently observed in nummular eczema.[2] 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.[1][3][4]

Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions of psoriasis, dermatitis, lichen planus and pityriasis rosea. Br. J.
