Alopecia neoplastica, a rare skin metastasis, typically presents as scarring alopecia. This case uniquely demonstrates alopecia neoplastica causing lytic bone metastasis, a previously undocumented mechanism.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Alopecia neoplastica is a rare cutaneous metastasis.
- It commonly presents as red-violaceous, scarring alopecia on the parietal scalp.
- Primary tumors are frequently from the breast or gastrointestinal tract.
Purpose of the Study:
- To report a unique case of alopecia neoplastica.
- To highlight its association with lytic bone metastasis.
- To document a previously undescribed mechanism of metastasis.
Main Methods:
- Case report.
- Comprehensive literature review.
Main Results:
- A patient presented with alopecia neoplastica.
- This condition was found to induce an underlying lytic bone metastasis.
- No similar cases were identified in the literature.
Conclusions:
- Alopecia neoplastica can present with unusual metastatic patterns.
- The induction of lytic bone metastasis by alopecia neoplastica is a novel finding.
- This case expands the understanding of cutaneous metastasis mechanisms.
