Pseudo-Kaposi's sarcoma because of suction-socket lower limb prosthesis

Area of Science:

• Vascular Surgery
• Dermatology
• Prosthetics

Background:

• Pseudo-Kaposi sarcoma, also known as acroangiodermatitis, is a benign vascular proliferation typically affecting the lower extremities.
• It is commonly associated with chronic venous insufficiency or arteriovenous malformations.
• Rare occurrences have been reported in amputees, hemodialysis patients, and individuals with paralyzed limbs.

Observation:

• A 28-year-old male presented with pseudo-Kaposi sarcoma.
• The lesions were located in the amputation stump of his lower limb.
• The patient utilized a suction-socket lower limb prosthesis.

Findings:

• This case represents a rare instance of pseudo-Kaposi sarcoma developing in an amputation stump.
• The development of lesions was potentially linked to the use of a suction-socket prosthesis.

Implications:

• This finding expands the known clinical spectrum of pseudo-Kaposi sarcoma.
• It underscores the importance of considering prosthetic-related factors in the etiology of vascular lesions in amputees.
• Further investigation into the biomechanical and physiological interactions between prosthetics and amputation stumps may be warranted.
