A retrospective study of 643 cutaneous horns examined in our department between 1970 and 1989 revealed that 38.9% were derived from malignant or premalignant epidermal lesions, and 61.1% from benign lesions. Four main features were associated with premalignant or malignant histopathological change at the base of a cutaneous horn (base pathology). These were: (i) age—the mean age of the patients whose cutaneous horns showed premalignant or malignant base pathology was 8–9 years greater than the… 
Morphological and histopathological analysis of cutaneous horn
TLDR
To examine the possibility of discrimination between benign cutaneous horn cases and malignant or premalignant ones by using their height-to-base ratio, such cases were compared from the standpoints of the morphological data as well as their ages.
A Prospective, Multicentre Study of Malignant and Premalignant Lesions at the Base of Periocular Cutaneous Horns
TLDR
The incidence of malignant and pre-malignant lesions present at the base of periocular cutaneous horns was 36% with 8% of them being malignant.
Cutaneous horns: are these lesions as innocent as they seem to be?
TLDR
Cutaneous horn is a clinical diagnosis that refers to a conical projection above the surface of the skin that typically occurs in sun exposed areas, particularly the face, ear, nose, forearms, and dorsum of hands.
Cutaneous Horn: A Devil Not Only in Appearance
TLDR
Cutaneous horn although an uncommon condition and usually neglected by the patient should be kept under high suspicion by the treating Surgeon and definitive management with wide local excision with adequate margins should always be explained to the patient.
Penile cutaneous horn: a rare case report and review of the literature
TLDR
It was difficult to establish a precise diagnosis of penile cutaneous horn preoperatively due to lack of any typical radiological features, so histopathological examination of the excised penile lesion was necessary for the postoperative definitive diagnosis.
Cutaneous horns: clues to invasive squamous cell carcinoma being present in the horn base
TLDR
Horns presenting on an invasive SCC base are more likely to have a height less than the diameter of the base, not to have terrace morphology, to have an erythematous base and to be painful.
A Curious Case of Cutaneous Horn
TLDR
A 58-year-old gentleman is presented who presented with a conical projection over the center of the forehead, which was clinically diagnosed as a cutaneous horn and the histopathology revealed benign seborrheic keratosis as the underlying lesion.
Giant Cutaneous Horn: Is It a Tip of An Iceberg? Two Case Reports and a Review of Literature
TLDR
Two cases of giant cutaneous horn associated with an underlying carcinoma presenting at an uncommon site are reported, both of which were adults and had a chronic history of a skin lesion over the affected sites.
Cutaneous Horn of the Eyelid in 13 Cases.
TLDR
The clinical significance of cutaneous horn of the eyelid lies not in the horn itself but the nature of the underlying base, which includes squamous cell carcinoma and sebaceous gland carcinoma.
Cutaneous horn malignant melanoma.
TLDR
This work is presenting an unpreviously recognized form of verrucous malignant melanoma arising as a cutaneous horn, which is commonly derived from a malignant base.

Cutaneous horns: a histopathologic study.
TLDR
A series of 230 cutaneous horns, of which fewer than one fourth were frankly malignant, are reported, finding lesions overlying a benign lichenoid keratosis, epidermolytic hyperker atosis, trichilemmoma, an epidermis.
Cutaneous horn (cornu cutaneum).
TLDR
A cutaneous horn (Cornu Cutaneum) is a relatively rare tumour, most often arising on sun-exposed skin in elderly men, usually after the Vth decade, and can be caused by many primary underlying processes that may be benign, premalignant or malignant.
