Marjolin's Ulcer of the Tibia With Pelvic Lymph Node Metastasis.

Marjolin's ulcer, a form of squamous cell carcinoma, is a rare complication of a chronic wound infection. To date, there have not been any detailed reports of lymphatic spread of Marjolin's ulcer from an extremity. This report describes a 44-year old male with a history of an open tibia fracture at age 15, who presented with chronic osteomyelitis, increasing bloody wound drainage, and an enlarging vascular exophytic masses in the region of drainage. Biopsy of the mass showed squamous cell carcinoma. Initial staging with computed tomography (CT) was negative for metastatic disease. Six months after undergoing a below-knee amputation (BKA), the patient developed an enlarged lymph node in the left inguinal area. His re-staging CT and biopsy of inguinal node confirmed the presence of metastatic squamous cell carcinoma. The patient was subsequently treated with inguinal node dissection and adjuvant radiation therapy. At 2.5 years follow-up, the patient remains disease-free. Our case illustrates the importance suspecting squamous cell carcinoma in patients with chronic infections and diligent follow up for patients with Marjolin's ulcers.
