Acute Squamous Cell Carcinoma

Description

Presented in right lateral profile, the male head and neck are rendered with clear surface landmarks of the auricle, lateral canthus, nasal dorsum, nasolabial fold, and the contours of the zygomatic arch over the maxilla and mandible. On the malar cheek, a raised keratinized projection consistent with a cutaneous horn rises from an erythematous, indurated base in the superficial soft tissues overlying the zygomatic region. The lesion sits anterior to the tragus and inferior to the lateral orbital rim, placing it on a typical sun-exposed facial subunit where epithelial malignancy often declares itself. Cutaneous horns are a morphology, not a diagnosis, and this view emphasizes the clinical problem: the horn frequently overlies actinic keratosis, keratoacanthoma, or squamous cell carcinoma, with the probability of invasive squamous cell carcinoma increasing when the base is tender, inflamed, broad, or fixed. Facial squamous cell carcinoma matters because tumors on the cheek can track along adnexal structures and invade perineural planes, producing pain, paresthesia, or subtle motor findings, and they carry metastatic risk to the parotid and upper cervical lymph nodes. Management hinges on sampling the base, not the horn, and definitive treatment often involves complete excision with histologic margin control (Mohs micrographic surgery is commonly chosen on cosmetically and functionally sensitive face). Use this asset for dermatology and head and neck oncology teaching, patient-facing counseling materials on skin cancer warning signs, or editorial figures discussing cutaneous horn differential diagnosis and biopsy technique. It also fits surgical texts outlining facial skin cancer excision planning and lymphatic drainage patterns relevant to parotid basin assessment.
