- Introduction: Chronic venous insufficiency causes skin pigmentation of the leg ranging from small patches of mild dyschromia to extensive areas of severe skin pigmentation. It is thought that the pigmentation is mainly due to haemosiderin or melanin deposition. Erythrodiapedesis which occurs as a result of venular hypertension causes erythrocytes to migrate across the microvascular network into the dermis. Methods: We categorized the grading of pigmentation into four grades: +, few spots; ++, pigmentation over gaiter area; +++, pigmentation involving leg and ankle; ++++, heavily pigmented (dark). Skin biopsies were taken from the patient while undergoing surgery; two biopsies were taken from each patient, one from apparently normal skin and other from the site of pigmentation. A total of 45 patients diagnosed as chronic venous insufficiency with pigmentation were included in the study and five patients included in control. The biopsy specimens were sent to pathology department for H&E, Perls stain and IHC for S100. Results: Majority of cases, i.e. 62% of limbs fall under (++) grade of pigmentation, followed by (+) grade of pigmentation in 20%, while (+++) and (++++) constitute 9% of the cases each. Increased melanin deposition was seen in 40 pigmented skin biopsies and 3 normal skin biopsies from the case group, and normal melanin deposition was seen in all the non-varicose controls. Conclusion: We have tried to categorize pigmentation in chronic venous insufficiency intoIntroduction: Chronic venous insufficiency causes skin pigmentation of the leg ranging from small patches of mild dyschromia to extensive areas of severe skin pigmentation.

Conclusion: We have tried to categorize pigmentation in chronic venous insufficiency into four grades. As the grade of pigmentation increases the per cent of cases with ulceration is increasing. It was observed that presence of melanin deposition irrespective of the grade of pigmentation was distributed more towards the advanced clinical classification (C5 and C6). … (more)
