Unveiling the Rare: A Case of Renal Cell Carcinoma Acrometastasis

Acrometastasis refers to a rare form of skeletal metastasis affecting sites distal to the knees and elbows, often leading to significant functional impairment and reduced quality of life. This case report details a 65-year-old man with a history of renal cell carcinoma (RCC) who presented with persistent pain and swelling in the distal aspect of his left long finger. An incisional biopsy confirmed the lesion as metastatic RCC. X-ray and MRI assessed the lesion's progression, guiding the treatment plan. The patient subsequently underwent disarticulation of the distal interphalangeal joint and was followed up one-month post-surgery before relocating and being admitted to hospice care. This report underscores the importance of recognizing acrometastasis as a potential indicator of recurrence in patients with a malignancy history. Although the prognosis for acrometastasis is generally poor, early identification and intervention are essential for improving patient outcomes.
