Raised seborrheic keratosis

Raised seborrheic keratosis refers to an elevated, benign cutaneous neoplasm of the integumentary system arising from the clonal proliferation of immature epidermal keratinocytes

Raised seborrheic keratosis refers to an elevated, benign cutaneous neoplasm of the integumentary system arising from the clonal proliferation of immature epidermal keratinocytes Clinically, these lesions are distinguished by well-demarcated, exophytic papules or plaques with a hyperkeratotic, waxy, or verrucous texture that imparts a characteristic "stuck-on" appearance, ranging in pigmentation from tan or yellow to deep brown or black

Most frequently presenting in middle-aged and older adults, lesions typically develop on sun-exposed or trunk areas—such as the face, neck, chest, and back—while characteristically sparing the palms and soles Clinically, these lesions are distinguished by well-demarcated, exophytic papules or plaques with a hyperkeratotic, waxy, or verrucous texture that imparts a characteristic "stuck-on" appearance, ranging in pigmentation from tan or yellow to deep brown or black

Histopathologically, they exhibit marked epidermal thickening (acanthosis), hyperkeratosis, papillomatosis, and prominent keratin-filled invaginations known as pseudo-horn cysts
