Summary
This case report details an exceptionally large basal cell carcinoma in a Japanese male, which led to systemic complications and death. The massive tumor caused anemia, hypoproteinemia, and widespread amyloidosis.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Basal cell carcinoma (BCC) is the most common type of skin cancer.
- Giant BCCs are rare, with limited documentation on their systemic impact.
Observation:
- A 61-year-old Japanese male presented with a massive, ulcerating BCC on his back, measuring 39 x 26 cm.
- The patient had a 30-year history of hiding the tumor, leading to advanced disease.
Findings:
- Histological confirmation of BCC.
- The tumor was associated with anemia, hypoproteinemia, dyspnea, and systemic amyloidosis affecting skin, lymph nodes, and the intestinal tract.
- Metastases to regional lymph nodes, bone, and lung were observed.
Implications:
- This case highlights the potential for locally advanced BCC to cause severe systemic complications and mortality.
- Undiagnosed and untreated giant BCC can lead to life-threatening conditions like systemic amyloidosis and widespread metastasis.
- Emphasizes the importance of early detection and treatment of skin malignancies.
