“…Dermatoscopy helps in the diagnosis of many pigmented skin lesions such as SK, pigmented basal cell carcinoma, hemangioma, blue nevus, atypical nevus, and cutaneous melanoma. [12] It is 10–27% more sensitive than the clinical criteria of ABCD (asymmetry, border regularity, color distribution, and diameter) in the early diagnosis of cutaneous melanoma. [1314] Dermatoscopy of melanocytic lesions increases the presurgical accuracy rate of clinical diagnosis from 50% to 85%.…”

A clinicopathological and dermoscopic correlation of seborrheic keratosis

Background:Seborrheic keratosis (SK) is the most common benign epidermal tumor of the skin. Even though SK has been well characterized clinically, dermoscopically, and histopathologically, data regarding clinical dermoscopic and histopathological correlation of different types of SK are inadequate.Aim:We carried out this study to establish any correlation between the clinical, dermoscopic, and histopathological appearance of SK and its variants.Methods:This was a descriptive study. Patients with SK were evaluated with respect to age, sex, family history of similar lesions, site of lesions, and symptoms associated with the lesions. Dermoscopy was performed in all cases. Biopsies were taken from the lesions and assessed for histopathology.Results:The most common age group affected by SK was 31–50 years (42%). A female preponderance of 76% was seen. Majority of our patients had a positive family history (62%), though Sun exposure was not seen to be a major factor. The most common clinical variant was common SK (CSK) (46%). The most common dermoscopic findings seen in CSK were comedo-like (CL) openings, fissures and ridges (FR), and milia-like (ML) cysts. Dermatosis papulosa nigra and pedunculated SK had characteristic FR and CL openings on dermoscopy. Stucco keratoses showed network-like (NL) structures and sharp demarcation. CL opening on dermoscopy corresponded to papillomatosis and pigmentation, ML cysts corresponded to horn cysts, FR corresponded to papillomatosis, and NL structures corresponded to an increase in basal layer pigmentation.Conclusions:This study emphasizes the use of dermoscopy in improving the diagnostic accuracy of SK. The correlation between the various histological and dermoscopic features is described.

“…Non-pigmented BCCs are much more prevalent than pigmented BCCs. Sometimes it could be difficult to distinguish a pigmented BCC from a melanoma [1]. Menzies et al suggested a dermatoscopic method with a sensitivity of 93% and a specificity of 89% for diagnosing pigmented BCCs (See Table) [2,3].…”

Multiple dermatofibromas: Dermoscopic patterns

et al. 2013

View full text Add to dashboard Cite

Dermatofibromas are benign skin lesions that consist of pigmented papules or nodules. They produce the dimple sign when laterally squeezed and are usually found on the legs. These clinical features lead to the diagnosis in most cases. However, the differential diagnosis with other lesions, such as atypical nevi and melanoma can be difficult, and the dermoscopy may help the diagnosis. There are several dermoscopic patterns associated with dermatofibromas, the most common being a central white scar like patch with delicate pigment network at the periphery. This article describes the case of a patient who had eleven clinically similar dermatofibromas, with four distinct patterns when submitted to dermoscopic examination.

Dermatoscopy of non-melanocytic skin tumors

Abstract: Dermatoscopy is a cheap and non-invasive diagnostic technique that improves the diagnostic accuracy of non-pigmented benign and malignant skin tumors. Dermatologist should be aware of dermatoscopic features of non-melanocytic skin tumors to reach the correct diagnosis.
