CPC on Dermatological Skin Manifestations of Diabetes
Introduction
Dr. Arfa Ikram Afridi, Senior Registrar at the Dermatology Unit, Jinnah Medical College & Teaching Hospital, delivered a clinico-pathological conference (CPC) on Dermatological Manifestations of Diabetes Mellitus.
The presentation focused on recognizing common and clinically significant skin disorders associated with diabetes, understanding their underlying pathophysiology, and emphasizing the role of cutaneous findings as early indicators of undiagnosed or poorly controlled diabetes.
Key Points
Cutaneous involvement is common in diabetes, with approximately one-third of diabetic patients developing skin manifestations during the course of their illness, sometimes even preceding the diagnosis.
The presentation highlighted classification of diabetic skin manifestations, including:
Infections (fungal and bacterial)
Granulomatous disorders (Granuloma Annulare, Necrobiosis Lipoidica)
Obesity and dyslipidemia-related conditions
Treatment-related skin diseases
Stiff skin and joint syndromes
Granuloma Annulare was discussed as a common inflammatory dermatosis strongly associated with diabetes, emphasizing its clinical features, pathogenesis related to hyperglycemia and microangiopathy, and usually benign course.
Necrobiosis Lipoidica Diabeticorum was identified as a rare but important condition in diabetic patients, particularly females, with a risk of ulceration and association with microvascular complications.
Scleredema Diabeticorum was presented as a chronic and disabling condition linked to poor glycemic control, characterized by skin thickening due to collagen glycation and mucin deposition.
Reactive Perforating Collagenosis was highlighted as a perforating dermatosis commonly associated with diabetes and chronic renal disease, presenting with pruritic papules and transepithelial elimination of collagen.
The discussion emphasized that microangiopathy, impaired immunity, and chronic hyperglycemia are the key mechanisms responsible for most diabetic skin changes.
Early recognition of skin manifestations can aid in timely diagnosis of diabetes, assessment of glycemic control, and prevention of long-term complications.
