Ectopic sebaceous glands without attached hair follicle may be present near mucocutaneous junction. 

Clinical presentation:   

The incidence of Fordyce's granules increases from childhood to adulthood, and is slightly higher in men.

Presents as tiny yellow papules. 


Fordyce's Spots - Present along vermillion border of the lips or on the oral mucosa.

Montgomery's tubercle-  Normal sebaceous glands are distributed along a circle in the periphery of the areola of the breast.

Ectopic sebaceous glands are occasionally found in other sites -

Normal sebaceous glands on the vermilion border of the lips and the oral mucosa are common in adults.

Only pathologic sebaceous glands visible through the epithelium should be regarded as Fordyce's granules.


Microscopic features:    

Histology shows a single sebaceous gland lesion consisting of single or a group of small but mature sebaceous lobules around small sebaceous duct extending to the surface epithelium.
