A 58-year-old woman presented with a painful, rapidly progressive ulcerative growth in her right gluteal region over the past 4 months. On examination, there was a large 10x8x4cm ulcerative growth with irregular shape, everted edges and margins, and surrounding thickened skin. The growth was fixed to the skin and gluteus maximus muscle. A provisional diagnosis of squamous cell carcinoma was made based on the clinical findings.
