Subclinical syringoma coexisting with basal cell carcinoma
The Journal of Dermatologic Surgery and Oncology
|July 1, 1987
Summary
Clinically hidden syringoma can be incidentally found alongside basal cell carcinoma (BCC) during Mohs surgery. Differentiating these tumors is crucial to prevent unnecessary surgical removal beyond BCC treatment.
Area of Science:
- Dermatopathology
- Surgical Oncology
Background:
- Basal cell carcinoma (BCC) is a common skin cancer.
- Mohs micrographic excision is a specialized surgical technique for skin cancer removal.
Observation:
- Three cases of clinically unapparent syringoma were incidentally discovered.
- Syringomas were found on frozen tissue sections during Mohs surgery for BCC.
- The tumors (syringoma and BCC) were either admixed or in close proximity.
Findings:
- Syringoma can coexist with basal cell carcinoma.
- These co-occurrences were observed in elderly women on facial skin.
- Detection occurred during routine histopathological examination of BCC surgical margins.
Implications:
- The presence of benign syringoma should be considered during Mohs surgery for BCC.
- Accurate differentiation between syringoma and BCC is essential.
- Avoiding over-excision beyond BCC resection is critical for optimal patient outcomes.
