TLDR Researchers found a new sign of fungal infection in some patients with Seborrheic Dermatitis.
In a 2019 study involving 16 patients with Seborrheic Dermatitis (SD), researchers discovered three new trichoscopic signs: the "dandelion" vascular conglomerate, the "cherry blossom" vascular pattern, and intrafollicular oily material.
