title: Syringocystadenoma papilliferum of the upper lip.
abstract: Syringocystadenoma papilliferum (SCAP) is a rare skin tumour believed to arise from the apocrine or eccrine sweat glands. It appears predominantly in childhood, usually at birth. It is exceedingly rare for it to appear on the upper lip. We report a case of SCAP in a 10-year-old Omani girl who presented to the Sultan Qaboos University Hospital in Muscat, Oman, in February 2012 with a non-tender, non-pruritic, solitary verrucous papule of 4 × 5 mm on the left side of the upper lip. It had been present since birth and had slowly been increasing in size over the years. It was occasionally associated with recurrent ulceration and bleeding and had previously been misdiagnosed and mismanaged. An excisional biopsy was performed and the whole lesion was removed. The surgical site was then sutured and the patient was discharged on the same day.
