When it comes to basal cell carcinoma (BCC), dermoscopy is primarily a diagnostic aid, helping in its discrimination from other cutaneous tumours and morphologically similar dermatoses. It also has a role in subtyping, since it provides clincopathological correlation, especially in pigmented BCC. And lastly, its role as a prognosticator, by assessing the extension of the tumour beyond clinically visible margins, and by gauging the response to various non-ablative treatments in follow-up visits. The dermoscopic compendium and diagnostic criteria for basal cell carcinoma (BCC) have been described in global literature, over the last two decades. We report a case, wherein, all eleven diagnostic criteria were found in a single dermoscopic frame. This can be helpful for teaching purposes and educational demonstrations.

A 59-year-old woman presented to the dermatology department with the chief complaint of a black facial patch, of 7 months’ duration, which had increased in size, and begun bleeding, spontaneously, over the course of the past 5 weeks. Cutaneous examination revealed a solitary, well-circumscribed hyperpigmented (black to brown) plaque measuring 4 cm over

examination. Contact polarized dermoscopy, with an immersion fluid, was performed, which revealed findings of: blue-gray-ovoid clods and globules, pigmented maple-leaf and spoke-wheel structures, a pinkish-white backdrop, short white chrysaloid lines, white amorphous areas, ulceration, erosions and atypical vasculature in the form of arborizing telangiectasia, red dots and areas of hemorrhage.

features described , and seen in our figure, have been tabulated as Table-1. A clinical and dermoscopic diagnosis of pigmented basal cell carcinoma was made. A 4-mm punch biopsy from the edge of the lesion showed basaloid cell nests with peripheral palisading, and a few stromal retraction artefacts, all consistent with the clinical diagnosis. A multi-disciplinary approach was initiated, and still on follow-up and close monitoring. This case shows all the dermoscopic signs that have been reported in BCC, in one single picture, and re-emphasizes the role of the elementary, handy dermatoscope in a dermatological setup.
