DR [page 22] [Dermatology Reports 2011; 3:e11] Chronic lymphoedema caused by recurrent infections in a patient with allergic hand eczema Beatrice Dyring-Andersen, Lone Skov, Peter Jensen Department of Dermato-Allergology, Copenhagen University Hospital Gentofte, Copenhagen, Denmark Abstract Allergic contact dermatitis is very common and may be complicated by secondary infec- tions. Chronic lymphoedema is a potentially debilitating condition, which may occur due to secondary infections or the dermatitis itself. The problem of chronic lymphoedema follow- ing allergic contact dermatitis has been infre- quently reported. We report a case of a 47-year- old woman with severe allergic contact der- matitis complicated by chronic, intractable lymphoedema of the hands and forearms. This case report reminds us that allergic hand der- matitis may be complicated by a chronic and debilitating state of lymphoedema. Also, it underlines the importance of fast and ade- quate treatment of both the dermatitis and the secondary infections. Introduction Allergic contact dermatitis is a common dis- ease, which may be complicated by secondary infections. Chronic lymphoedema due to destruction of lymphatic vessels is a potential- ly debilitating condition, which may occur due to secondary infections or the dermatitis itself. The problem of chronic lymphoedema follow- ing allergic contact dermatitis has been infre- quently reported.1-5 Case Report We report a case of a 47-year-old woman with severe allergic contact dermatitis compli- cated by chronic lymphoedema. At time of referral, clinical examination showed acute eczema on the hands. Patch testing was per- formed with the European Standard series using Finn Chambers© (Epitest., Oy, Finland) on Scanpor tape© (Norgesplaster A/S, Alpharma, As, Norway). The patch tests were applied to the upper back and occluded for two days and readings were done on D2, D3 and D7. There were positive reactions to formalde- hyde, chromium, balsam of Peru, sesquiter- pene lactone mix and colophonium. All reac- tions were of clinical relevance for the patient, who worked as a kindergarten teacher. The patient was instructed to avoid the known allergens and treatment with topical steroid was initiated but with little effect on the dermatitis. Over the following months she had numerous secondary infections, which necessitated several courses of systemic antibiotic therapy. To achieve disease control, the patient received therapy with per oral pred- nisolone followed by treatment with azathio- prine. However, because of her Compositae allergy, the hand eczema flared every summer and despite systemic anti-inflammatory treat- ment it was often complicated by secondary infections (Staphylococcus aureus) with lym- phangitis. Every infectious episode was treat- ed with relevant antibiotics often in combina- tion with potassium permanganate baths. In spite of this, the patient developed chronic lymphoedema of the hands and forearms (Figure 1). The diagnosis was confirmed by a lymphoscintigraphy which showed complete functional failure of the peripheral lymphatic vessels. Now, two years later, the patient is being treated with compression garments with limited effect. She remains unable to work as a kindergarten teacher and she was also unable to complete a work rehabilitation programme due to her swollen and painful arms. Discussion We describe here a case of a chronic debili- tating lymphoedema of the hands and fore- arms secondary to recurrent infections in a woman with severe, intractable allergic hand dermatitis. Chronic lymphoedema secondary to allergic or irritant contact dermatitis has been infrequently reported.1-5 Approximately half of the patients have no history of infection involving the affected areas prior to the debut of lymphoedema.1-5 Therefore, one may give consideration to the aetiology of the lym- phoedema and the pathology involved in the destruction of the lymphatic vessels. A plausi- ble mechanism in the present case could be obliterating bacterial lymphangitis which may lead to lymphatic insufficiency in patients with recurrent secondary infections. In patients with chronic lymphoedema without recurrent infections, damage to the lymphatic vessels may be caused by the harmful effect of the der- matitis itself.1,2 This case report reminds us that allergic hand dermatitis may be complicated by a chronic and debilitating state of lymphoedema. Also, it underlines the importance of fast and adequate treatment of both the dermatitis and the secondary infections. References 1. Worm AM, Staberg B, Thomsen K.
