Folliculosebaceous Cystic Hamartoma Of The Upper Lip And Labial Mucosa

Folliculosebaceous cystic hamartoma is a rare cutaneous hamartoma consisting of dilated folliculosebaceous structures interspersed within mesenchymal elements. These lesions may present as 0.5- to 3.0-cm papules or exophytic nodules and are usually solitary, symmetric, asymptomatic, dome-shaped, or even umbilicated. The usual location is the midface and scalp of adults. We present a unique case of a mucocutaneous folliculosebaceous cystic hamartoma involving the upper lip and oral mucosa. General practitioners and oral health care providers should be sentient of this lesion and consider it in their differential diagnoses. Keywords: cystic, folliculosebaceous, hamartoma
