Summary
Basal cell carcinoma developed at a smallpox vaccination scar in a 52-year-old woman. This rare occurrence highlights the importance of monitoring vaccination sites for potential neoplastic changes.
Area of Science:
- Dermatology
- Oncology
Background:
- Smallpox vaccination scars are generally considered benign.
- Neoplasms arising at vaccination sites are exceptionally rare.
Observation:
- A 52-year-old woman presented with erythema and scaling at her right deltoid smallpox vaccination scar, noted at age 50.
- Two years later, a nodule appeared and enlarged over three months.
- No history of significant sun exposure or other sun-induced skin lesions was reported.
Findings:
- Histological examination confirmed solid-type basal cell carcinoma (BCC).
- This represents a rare instance of a non-melanoma skin cancer developing at a vaccination site.
Implications:
- The case suggests a potential, albeit uncommon, link between vaccination scars and subsequent BCC development.
- Further research into the etiopathogenesis and clinical significance of such occurrences is warranted.
- Clinicians should be aware of the possibility of BCC arising in vaccination scars, irrespective of sun exposure history.
