Dermoscopic yellow structures in basal cell carcinoma

Background Yellowish structures in dermoscopy comprise milia‐like cysts ( MLC s) and yellow lobular‐like structures. Objective This study aimed at establishing the frequency of these features in BCC and at describing their dermoscopic details. Methods A retrospective analysis of digital dermoscopic images referring to 400 BCC s was performed. Images were evaluated for the presence of starry and cloudy MLC s and yellow lobular‐like structures. Results Among the 400 BCC s constituting our database, 40 presented yellowish structures (10%). “Yellow” BCC s were located more frequently on the head and were mainly of the nodular type. MLC s were observed in 7.75% of the cases (with a mean number of 4.9 MLC s per lesion), whereas yellow globules were noticed in 4.2% /ucodep of the lesions. Conclusion In the presence of BCC specific dermoscopic criteria, the observation of MLC s and yellow lobular‐like structures should not prompt the dermatologist to exclude the diagnosis of BCC .
