Cutaneous horn is the clinical description of a hyperproliferation of compact keratin in response to a wide array of underlying benign and malignant pathologic changes. We report here on a case of cutaneous horn that originated from keratoacanthoma in a 76-year-old woman. Grossly, a 2.5×0.7 cm sized yellow-white colored scaly fungating mass from an erythematous nodule was observed on the right ...

INTRODUCTION A cutaneous horn is a conical projection of hyperkeratotic epidermis. Though grossly resembling an animal horn, it lacks a bony core. These lesions have been well described in Caucasian patients, as well as in a number of Arabic and Asian patients. CASE PRESENTATION A young female presented with a large 'horn' of five-year duration, arising from a burn scar. Excision and scalp re...

Cutaneous horns are usually found on chronic sun-damaged skin. A cutaneous horn is a rare tumour, often conical, circumscribed, and composed of dead keratin usually derived from base keratinocytes. It occurs mainly in association with underlying benign, premalignant, and malignant cutaneous diseases. The commonest malignancy is squamous cell carcinoma. Thus, to accurately ascertain the nature o...

Cutaneous horn is a protrusion from the skin consisting of cornified material. It usually appears on exposed skin areas especially on the head and neck. A 70-year-old woman applied to our clinic with a hard, conical, black-grey 2 cm lesion on the upper lip. On physical examination, there was no palpable lymph node in the neck other than the lesion. Diagnosed to be cutaneous horn, the lesion was...

Context: Cornu cutaneum associated with squamous cell carcinoma is a relatively unusual presentation in lower lip. Cutaneous horn may be associated with benign, premalignant, or malignant cutaneous lesions and is characterized by the presence of abnormal keratinized material. Here we present a 63-year-old female patient with a cutaneous horn in lower lip with underlying squamous cell carcinoma ...

BACKGROUND Cutaneous horns (cornu cutaneum) are uncommon lesions consisting of keratotic material resembling that of an animal horn. Cutaneous horn may arise from a wide range of the epidermal lesions, which may be benign, premalignant or malignant. PATIENTS AND METHODS In this respective study, we describe our experience of eleven patients with cutaneous horn treated at our centre between Ja...
