Diagnosis
Histopathology is the basis of diagnosis. Stratified-squamous epithelium with a granular layer that surrounding a cystic space filled with laminated keratin and a variable number of vellus hair cysts is seen to be present.[3] It can be difficult to distinguish from other skin conditions, including molluscum contagiosum and acne vulgaris but can be corroborated with histopathology.[4]
Associations
It can be associated with Steatocystoma multiplex.[3]
Treatment
Therapeutic techniques that are safe and effective are rare, with incision and drainage being the primary form of treatment when sporadic regression does not occur.[5] The primary indication for treatment is cosmesis. Retinoids, surgery, and lasers are used as treatment modalities.[3]
