Basal Cell Carcinoma (BCC) In contrast to SCC, there are no known precursor lesions for BCC. The classic presentation described for nodular BCC is a ‘pearly’ telangiectatic nodule with rolled borders. Central ulceration or crusting may occur. The nodular subtype accounts for approximately 60 % of BCC, but it can also be superficial or morpheaform. Superficial BCC may be a plaque or a papule and is pink/red in colour. Morpheaform lesions are smooth, flesh-coloured plaques or papules resembling scars with illdefined borders .

Haberal et al. conducted a prospective study of 48 patients with head and neck cancer undergoing neck dissection, and compared the modalities of palpation, ultrasound and CT findings to the gold standard of histopathology of lymph nodes . They found palpation had a positive predictive value and negative predictive value of 78 % and 74 %, respectively. In comparison, the corresponding values for ultrasound were 94 and 80 %, and for CT 90 and 85 %.
The World Health Organization’s Pathology and Genetics of Skin Tumours (2006) outlines several histological variants of SCC . • Acantholytic SCC. This variant is found often involving the head and neck. The islands of tumour cells demonstrate central acantholysis resulting in a pattern that appears gland-like [13, 15]. • Spindle cell SCC is rare and usually arises in sun-damaged or previously irradiated skin. These spindle-shaped tumour cells have large vesicular nuclei with numerous mitoses and minimal eosinophilc cytoplasm [13, 15].
