What Is Pilar Sheath Acanthoma?
Pilar sheath acanthoma is a small tumor benign that originates from the follicle pilosebaceous unit. It typically presents as a papule solitary and discrete papule, reaching up to 5 mm in diameter, characterized by a small central depression or opening measuring 1 to 2 mm. It does not produce hair and, when squeezed, may release dead skin tissue. This growth is not associated with other medical syndromes or skin tumors.
This condition is more common in middle-aged men and women, frequently affecting the face and scalp. In many cases, the lesions lesions are located specifically on the upper lip. Beyond their physical appearance, these papules are asymptomatic.
