Suction Blister Epidermal Grafting for Management of Eyelid Vitiligo: Special Considerations

BACKGROUND: Suction blister epidermal grafting is an established technique for the treatment of resistant and stable vitiligo especially over small and cosmetically important areas like the face. However, certain areas, such as lips and eyelids, require special considerations because of their anatomic peculiarities. PATIENTS AND METHODS: The current study was carried out on six patients of stable eyelid vitiligo, not responding to medical treatment. Suction blister was obtained from the thigh using the suction apparatus and the roof was grafted on to the dermabraded eyelid. Certain precautions were taken during the procedure, which will be highlighted in the current study. RESULTS: Response was excellent in all the patients in 3 to 6 months, with no complications. CONCLUSIONS: If carried out properly, suction blister technique is the procedure of choice for cosmetically important sites like eyelids.     

Linear Nevus Sebaceus Syndrome with bilateral complex limbal choristomas and extraocular muscle involvement

A case of a child with bilateral fleshy limbal masses with a coloboma of the right upper lid is discussed. Systemic examination revealed two patches of alopecia on the right frontoparietal and right occipital areas of the scalp. Punch biopsy and histopathological examination led to the diagnosis of Linear Nevus Sebaceus Syndrome (LNSS) with bilateral complex limbal choristomas.

ANTISMOOTH MUSCLE AND ANTIPARIETAL CELL ANTIBODIES IN INDIANS WITH ALOPECIA AREATA

Background. Alopecia areata is suspected to be an autoimmune disease. We studied 104 consecutive patients with alopecia areata for the presence of autoantibodies and associated autoimmune diseases. Methods. A detailed history and examination was carried out in all patients to look for associated atopy, diabetes mellitus, hypertension, rheumatoid arthritis, vitiligo, lupus erythematosus, and thyroid disorders, etc. in the patients or their family members. Venous blood for estimation of fasting and postprandial blood glucose was collected in 30 patients, especially in those with family history of diabetes mellitus. Antimitochondrial (AMA), antismooth muscle (SMA), antinuclear antibodies (ANA), antiparietal cell antibody (PCA), and antibody against thyroid microsome (TMA) were detected employing indirect immunofluorescence on a composite section of rat liver, stomach, kidney, and human thyroid. Skin biopsy was processed for direct immunofluorescence by a conventional technique. Results. Disseminated discoid lupus erythematosus, lichen planus, urticaria, psoriasis, and seronegative spondylarthritis were associated with alopecia areata in one case each. Anti-smooth-muscle-antibodies and PCA were found in 36 (34.6%) and 44 (42.3%) patients respectively, followed by TMA in 8 (7.7%), AMA in 6 (5.7%), antithyroglobulin antibodies in 3 (2.8%), and ANA in 2 (1.9%) patients. The incidence of SMA was higher in men with alopecia areata (P< 0.001). Direct immunofluorescence carried out in 24 patients did not reveal significant findings, except for occasional immunoglobulin deposits around hair follicles and blood vessels. Conclusion. Alopecia areata in India is associated more often with antismooth muscle and antiparietal cell antibodies.
