“…A horn base may display benign or malignant histopathology. Horns with a benign histopathological base have a reported incidence ranging from 41% [1] to 60% [2, 3] and up to 77% on the eyelid [4]. Horn formation can occur in keratoacanthoma [5].…”

Background:Cutaneous horns usually develop on a keratinocytic base with the histopathology on a spectrum ranging from benign keratosis through to invasive squamous cell carcinoma (SCC). Some features of horns are easily identified using dermatoscopy.Objective:To investigate if specific clinical or dermatoscopy features of horns correlate with the histopathology in the base of the horn.Methods:Consecutive horn cases (n=163) were assessed prospectively in vivo for horn height, terrace morphology and base erythema using a Heine Delta 20 dermatoscope. Cases with potentially confounding influences were excluded. A history of horn pain or pain on palpation was also recorded.Results:Benign keratosis (n = 49), actinic keratosis (n = 21), SCC in situ (n = 37) and invasive SCC (n = 56) were recorded. An invasive SCC presenting as a horn as most likely to have a height less than the base diameter, 66% (37/56). Compared to the other study entities, invasive SCC tends to have less terrace morphology (P<0.05), a higher incidence of base erythema (P<0.05) and more pain (P<0.01).Limitations:Data categories did not include anatomic site or horn growth rates. Excision selection bias favored the incidence of invasive SCC.Conclusions: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.

“…ese alternative methods of treatment are mostly preferred in cases where the lesion is small and there is low grade of suspicion of malignancy [12].

Background.A cutaneous horn is a common clinical entity which usually presents as a cutaneous lesion. Because of its subtle nature, patients usually tend to present late unless the lesion is big or complications develop. Because of its resemblance to animal horn, it has been given the term "horn." Cutaneous horn seems to have a remarkable history. ough cutaneous horn is benign most of the times, chances of malignancy (20-25%) should be kept in mind. Old age, giant cutaneous horn carries more chances of transformation into malignancy like in our case. us, early diagnosis and treatment is required in all cases. Case Presentation. We report a case of a 74-year-old farmer with a cutaneous projection measuring ∼8 × 5 × 3 cm 3 over the medial surface of the right pinna for 1 year. It started as a small projection which was progressively enlarging. e primary reason behind him presenting to us was cosmetic reason since it resembled an animal horn. e projection was not associated with pain or similar lesions anywhere else in body. Understanding the malignancy risks and the cosmetic benefits, he was planned for excision biopsy of the horn. He had no systemic signs of malignancy. Histopathological reports were consistent with malignancy. Conclusions. Cutaneous horns are usually benign lesions and mostly found in the head and neck region. Because of the chances of malignancy, cutaneous horns should undergo surgical removal and biopsy for early and definitive diagnosis and management.

A cutaneous horn (corn cutaneum) is a dense, hyperkeratotic conical projection of skin arising from an unusual cohesiveness of keratinized material. Cutaneous horns most frequently occur in sites that are exposed to actinic radiation or burns. Forearm, cartilaginous portion of the ear, legs, and hands may also be affected. Cutaneous horns can occur in sun protected areas. Histologic confirmation is necessary to rule out malignant changes. No clinical features reliably distinguish between benign and malignant lesions. This is a case report of a cutaneous horn over inguinal region.
