Giant Cutaneous Horn of the Cheek: A Case Report

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.
