A 52-year-old woman presented with a 9-year history of multiple facial lesions. There had been no increase in the size of the lesions over years, and no seasonal changes or any changes in humid and hot environments. The patient had been taking propranolol for hypertension for 12 years. There was no family history of similar lesions.On physical examination, multiple, dark-blue, periorbital, asymptomatic macules, 3-8 mm in size, were seen on the patient's face (Fig. 1). The remainder of the clinical examinations revealed no abnormalities. Routine laboratory tests including full blood cell count, liver and renal function, glycaemia and thyroid hormones were within normal limits. Dermoscopy showed only a homogeneous, blue to black pattern (Fig. 2). Histopathological findingsOn histological examination, a cystic lesion was found in the reticular dermis. The cyst lining was composed of two layers of flat epithelial cells without signs of decapitation secretion (Fig. 3).
