To present a case of primary cutaneous adenoid cystic carcinoma (PCACC) and discuss its pathological, dermoscopic, and radiological characteristics, highlighting their significance in diagnosis and management.
Approach:
Key Findings:
PCACC is a rare malignant tumor that typically presents as a slow-growing, painless nodule, with implications for early detection.
Histopathological examination is essential for diagnosis, showing characteristic infiltrative growth and perineural invasion, which are critical for treatment planning.
Wide local excision is the standard treatment to minimize local recurrence, with follow-up necessary to ensure long-term outcomes.
Interpretation:
Dermoscopy can provide diagnostic clues, but definitive diagnosis requires histopathological evaluation, underscoring the need for comprehensive diagnostic approaches.
Limitations:
The case is based on a single patient, limiting generalizability and potential biases.
Long-term follow-up is necessary to assess recurrence risk and treatment efficacy.
Conclusion:
PCACC should be considered in the differential diagnosis of slow-growing cutaneous nodules, even in atypical locations, emphasizing the importance of early diagnosis and appropriate management.
