Squamous cell carcinoma developed on neglected, mistreated and delayed diagnosed chronic venous leg ulcer

Chronic venous leg ulcers (VLU), especially long-lasting non-healing ulcers, are among the risk factors for squamous cell carcinoma (SCC) with particularly aggressive behaviour. We present a case of a 71-year-old female patient with a relevant personal history of multiple SCC and basal cell carcinoma (BCC) excision and chronic venous insufficiency showing for about three years a ulcerated lesion located on the anteromedial distal third of the left leg non-responsive to specific treatment, which subsequently increased their size and merged. Biopsy sample was taken. Histopathology revealed a G2 SCC in all biopsy samples. After the staging, a left inguino-femoral lymphadenectomy and the excision were done. The treatment of bone exposure with a soleus muscle flap in the upper half of the defect and skin graft for all the defect and a specific oncologic treatment were proposed as possible curative solutions. Patients with chronic venous leg ulcers and clinically suspicious lesions should be evaluated for malignant transformation of the venous lesion. When diagnosed, malignancy complicating a chronic venous leg ulcer requires a resolute treatment as it may be fatal
