A 48-year-old female farmer presented with a painless lump in her left abdomen that had been rapidly increasing in size over the past month. On examination, a large, hard, irregular mass was palpated in the left lumbar region extending to the umbilicus. The mass was non-tender, non-mobile, and dull to percussion. Based on the location and characteristics of the mass, the provisional diagnosis was of a left-sided renal cell carcinoma. No signs of metastasis were found on further examination.
