Pilomatricoma, also known as calcifying epithelioma of Malherbe, is the most common adnexal tumour in children and young adults. It typically occurs on the head, neck or upper limb. Here, we report a case of bullous variant of pilomatricoma. A male adult presented a firm nodule covered by a sequent bulla on the left shoulder. Pathological examination showed the tumour was composed of irregularly shaped epithelial islands which included two cell types: basophilic cells and eosinophilic shadow cells. No cellular atypia or abnormal mitotic figures were observed. These findings were consistent with a diagnosis of pilomatricoma. The bulla was attributed to lymphatic obstruction that resulted in the dilation of lymphatic vessels. Our pilomatricoma had the unusual feature of a cross-shaped, giant bulla measuring 10 cm × 5 cm overlying the tumour. To our knowledge, it was the largest bullous pilomatricoma in the literature. After surgical resection, there was no recurrence.
