“…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]. Squamous cell carcinoma has been reported in 94% of horns with a malignant base [1].…”

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.

A 73-year-old Japanese woman presented with cutaneous horn on the right cheek. The resected tumor was 9 mm in diameter, with 14 mm protrusion, and showed exophytic growth with marked papillomatosis. Histopathology showed proliferation of atypical melanocytes with melanin pigments in the epidermis and dermis under the cutaneous horn. These cells were confined to the base of the cutaneous horn, and did not spread to the surrounding epidermis. The final diagnosis was cutaneous horn malignant melanoma. This pathological entity is considered a specific form of verrucous melanoma, and might be added to the list of cutaneous horn-forming lesions.

A Case of Cutaneous Horn Originating from Keratoacanthoma

Abstract: Fig. 1. A 3×3 cm sized erythematous patch with a central 1×1 cm sized hypertrophic nodule on the right temple. A yellowish-white colored cylindrical horn with a base diameter of 0.7 cm and a height of 2.7 cm arose from the central nodule.
