Ascher syndrome

Ascher syndrome (also known as Laffer-Ascher syndrome) is a rare congenital disorder characterized by a classic triad of clinical features: blepharochalasis (recurrent episodes of painless eyelid edema leading to stretching and thinning of the eyelid skin), double lip (a redundant fold of tissue on the inner mucosal surface of the upper lip that becomes prominent when smiling), and nontoxic thyroid enlargement (goiter). The condition primarily affects the face, involving the eyelids, lips, and thyroid gland. The double lip is typically the most consistent and recognizable feature, while the thyroid enlargement is present in a smaller proportion of affected individuals and is not always part of the presentation. Blepharochalasis episodes usually begin around puberty and may lead to progressive eyelid laxity and ptosis over time. The exact cause of Ascher syndrome remains unknown, and no specific gene has been identified. Most reported cases appear to be sporadic, though rare familial occurrences have been documented, suggesting a possible autosomal dominant inheritance pattern with variable expressivity. The condition affects both males and females. Diagnosis is primarily clinical, based on the recognition of the characteristic features. There is no specific medical treatment for Ascher syndrome. Management is primarily surgical and cosmetic, including blepharoplasty to correct eyelid redundancy and ptosis, surgical excision of the redundant lip tissue for functional and aesthetic improvement, and thyroidectomy if the goiter causes compressive symptoms. The prognosis is generally good, as the condition is benign and does not typically affect life expectancy. Fewer than 100 cases have been reported in the medical literature worldwide.
