Abstract:
Nonkeratinizing squamous cell carcinoma (NKSCC) of the sinonasal tract is a rare malignancy that infrequently presents with cutaneous extension. This case describes an unusual instance of extensive facial skin involvement in an elderly male with multiple comorbidities, diagnosed with a biopsy-proven NKSCC. The tumor was p16 positive, suggesting an HPV-related etiology. This case emphasizes the critical role of dermatologists in the early diagnosis and multidisciplinary management of such aggressive tumors. It highlights the necessity of including NKSCC in the differential diagnosis of destructive facial tumors. Dermatologists should remain vigilant for rare presentations and employ early biopsy and histopathological examinations to facilitate prompt multidisciplinary intervention. Recognizing p16 positivity can indicate a human papillomavirus (HPV)-related etiology, potentially influencing prognosis and management strategies.
Insights
This case study highlights an unusual facial skin extension of nonkeratinizing squamous cell carcinoma (NKSCC) of the sinonasal tract. Early dermatological diagnosis and multidisciplinary care are crucial for this rare, aggressive cancer.
Area of Science:
- Oncology
- Dermatology
- Pathology
Background:
- Nonkeratinizing squamous cell carcinoma (NKSCC) of the sinonasal tract is a rare malignancy.
- Cutaneous extension of sinonasal NKSCC is infrequent.
- Elderly patients often present with multiple comorbidities.
Observation:
- An elderly male with multiple comorbidities presented with extensive facial skin involvement.
- Biopsy confirmed nonkeratinizing squamous cell carcinoma (NKSCC) of the sinonasal tract.
- The tumor was p16 positive, indicating a potential human papillomavirus (HPV) etiology.
Findings:
- The case demonstrates an unusual presentation of sinonasal NKSCC with extensive facial cutaneous metastasis.
- P16 positivity suggests an HPV-driven carcinogenesis pathway.
- Histopathological examination and biopsy are essential for diagnosis.
Implications:
- Dermatologists play a vital role in the early detection of destructive facial tumors.
- NKSCC should be considered in the differential diagnosis of aggressive facial lesions.
- Prompt multidisciplinary management is critical for optimizing outcomes in rare cancer presentations.
- Identifying HPV-related etiology through p16 status can inform prognosis and treatment strategies.
