Trichofolliculomas show squamous epithelium lined cystic cavity within dermis enclosing keratinous material and hair shafts with numerous small secondary hair follicles emanating from the cyst wall.

Occasional keratinous cysts and a matrix of varying composition can also be found.7

The lesion was excised from base and specimen was sent for HPE, which showed only keratinous accumulation in epidermis, no specific pathology was found.

PC is a rare, autosomal dominant disorder characterized by triad of subungual hyperkeratosis with accumulation of hard keratinous material beneath the distal portion of the nails, lifting the nails from the nail bed, keratosis palmaris et plantaris with thick callosities, especially on the soles and thick white areas on the oral mucosa.4,5 Other associated features which may occur include keratosis pilaris, hyperkeratotic follicular papules on the sites of friction, hair abnormalities and hyperhidrosis of the palms and soles.

(5) The rupture of a cholesteatoma sac and the spillage of keratinous substance into the subepithelial layer usually causes a marked granulomatous reaction of a foreign-body type, but it is not associated with cholesterol crystals and hemosiderin-laden macrophages.
