| When Healing Turns Harmful: Skin Necrosis after Sclerotherapy Sclerotherapy is often a safe procedure for varicose veins; nevertheless, unusual problems such as skin necrosis may arise. This case details a 29-year-old man farmer who acquired a non-healing 2×2 cm ulcer on his left leg after ultrasound-guided sclerotherapy utilising sodium tetradecyl sulphate. Initially, hyperpigmentation at the injection site advanced to ulceration accompanied by serosanguinous discharge. Routine examinations yielded normal results, and a punch biopsy from surrounding skin verified the diagnosis of stasis dermatitis. Prolonged patient presentation and diagnosis resulted in more severe debilitating side effects. The example highlights the necessity for prompt identification, accurate injection methods, and diligent post-procedural observation. |
