Linear basal cell carcinoma (BCC) is a rare clinical variant of BCC. Its morphology is characterised by a linear tumour of at least 3:1 length-to-width ratio, with a predilection to extend along relaxed skin tension lines. In this study, we present a case of a 67-year-old male with a 75 by 25 mm linear BCC of the supraclavicular region, in association with prior trauma, with dermatoscopic features of ulceration, keratin scale, opaque stroma and sharply demarcated serpentine vessels. The clinical course, dermatoscopy, histopathology and management of this case were then related to previous literature concerning linear BCC. In conclusion, though rare, linear BCC is an underreported phenomenon, with a tendency to recur, and the mechanism behind its growth pattern yet to be understood. Further studies are required to elucidate its pathogenesis and establish treatment guidelines.
