Pilomatricoma, also known as calci fying epithelioma of Malherbe, is the most common adnexal tumour in children and young adults. It typical ly occurs on the head, neck or upper limb. Here, we report a case of bul lous variant of pilomatricoma. A male adult presented a firm nodule covered by a sequent bulla on the left shoul der. Pathological examination showed the tumour was composed of irregu larly shaped epithelial islands which in cluded two cell types: basophilic cells and eosinophilic shadow cells. No cel lular atypia or abnormal mitotic fig ures were observed. These findings were consistent with a diagnosis of pi lomatricoma. The bulla was attributed to lymphatic obstruction that resulted in the dilation of lymphatic vessels. Our pilomatricoma had the unusual fea ture of a crossshaped, 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.
