A 14-year-old boy presented with a slightly painful swelling on the upper back since 6 years of age. On clinical examination, a firm, 6 × 4 cm, bluish to erythematous tender swelling on left upper back overlying the scapula, was seen [Figure 1]a. It was freely mobile with slightly corrugated surface showing multiple facets (tent sign). Ultrasound showed hyperechoic margins with an echogenic center and absence of any calcification. Histological evaluation demonstrated a tumorous growth with lobules lined by basaloid cells with abrupt transition to eosinophilic material in the centre. On high-power view, keratinized cells with empty appearing “ghost cells” having shadows of nuclei within were seen [Figure 1]b. There was minimal background inflammation with absence of any focal calcification or giant cell formation. On the basis of clinical, radiological and histopathological features, giant pilomatricoma was diagnosed and was surgically excised.
