Subcutaneous ("inverted") verrucous carcinoma with bone invasion
The American Journal of Dermatopathology
|February 1, 1997
Summary
Verrucous carcinoma (VC), a rare skin cancer, can occur on the buttock. This case highlights a unique subcutaneous presentation with significant iliac bone erosion.
Area of Science:
- Dermatology
- Oncology
- Surgical Pathology
Background:
- Verrucous carcinoma (VC) is a rare, low-grade variant of squamous cell carcinoma.
- It commonly affects the foot, where it is termed carcinoma cuniculatum.
- Previous reports of VC on the buttock are limited to three documented cases.
Observation:
- This report details an exceptionally rare case of verrucous carcinoma originating in the buttock.
- The tumor exhibited extensive erosion into the adjacent iliac bone.
- A unique characteristic was its entirely subcutaneous location, deviating from typical presentations.
Findings:
- The presented case represents a highly unusual subcutaneous verrucous carcinoma of the buttock.
- Significant iliac bone erosion was a prominent feature, indicating aggressive local invasion.
- The tumor's exclusively subcutaneous nature is a novel finding in the literature.
Implications:
- This case expands the known clinical spectrum and anatomical locations of verrucous carcinoma.
- It underscores the importance of considering rare presentations, even in subcutaneous tissues.
- Further investigation into the behavior and management of subcutaneous VC with bone involvement is warranted.
