A Rare Case of Pilomatricoma with Bullous Appearance

A 16-year-old girl with three months history of hard swelling on her left shoulder was admitted to our clinic. The mass emerged 3 months ago and bullous formation associated swelling appeared during the last month. There was no trauma history. Family and past medical history was unremarkable. Systemic examination was normal. Physical examination revealed no regional lymphadenopathy. In dermatologic examination, there was a 2 × 1.6 cm, firm, mobile, multilobule, non-tender mass on the left infraclavicular region. A 1.8 × 1 cm soft, hemorrhagic blister-like formation was detected on the mass (Figure 1). Laboratory examination (complete blood count, serum biochemical and urine analysis, PA thorax radiography) was in normal limits.
