A cutaneous horn is an uncommon lesion characterized by excessive keratinization, which protrudes above the skin surface and predominantly occurs on sun‐exposed areas. Currently, the exact incidence and prevalence of this disease are not well‐documented in the literature. An 83‐year‐old female patient presented with a cutaneous lesion in the left cheek for more than 15 years. Physical examination revealed the lesion size approximately accounted for 4 cm in length and 1.5 cm in diameter at the base, with a firm, nonerythematous, and painless swelling at its base. The lesion exhibited a distinctive appearance, resembling a large rooster’s spur. Ultrasonographic record identified no definite evidence of deep subcutaneous invasion. To establish a definitive diagnosis, a preoperative biopsy was conducted, which histologically demonstrated a combination of squamous epithelial cells and keratinized debris. Treatment involved local anesthesia and surgical excision therapy. Postoperative management included the administration of antibiotics, NSAIDs for pain relief, and anti‐inflammatory medications. The wound demonstrated favorable healing progress by the first postoperative day. The effective management of cutaneous horn necessitates a comprehensive approach involving precise diagnostic evaluation, proficient surgical excision, and diligent postoperative follow‐up. This case study enhances the current understanding of this uncommon condition and underscores its implications for improving clinical outcomes and patient care.
