Rapp-Hodgkin syndrome (RHS) is a rare type of autosomal dominant disorder characterized by association of ectodermal dysplasia (ED) with cleft lip/palate. The main features include dry, brittle hair with alopecia in adulthood, dental anomalies (hypodontia, microdontia with delayed eruption, fissured tongue, and retruded maxilla), hypohidrosis, dysplastic nails, and clefting. Palmar-plantar keratoderma is seen frequently. RHS has signs and symptoms that overlap considerably with those of ankyloblepharon-ED-clefting syndrome and ectrodactyly-ED-clefting syndrome. This manuscript discusses a case of RHS, one of the four members in three generations who had ED with variable degree of involvement of hair, teeth, nail, and sweat glands.
拉普-霍奇金综合征（RHS）是一种罕见的常染色体显性疾病，其特征为外胚层发育不良（ED）与唇腭裂相关联。主要特征包括成年后头发干燥、易脆并伴有脱发，牙齿异常（牙齿发育不全、小牙伴萌出延迟、沟纹舌和上颌后缩），少汗，指甲发育异常，以及腭裂。掌跖角化病较为常见。RHS的体征和症状与睑缘粘连-外胚层发育不良-腭裂综合征和缺指（趾）-外胚层发育不良-腭裂综合征有相当大的重叠。本文讨论了一例RHS病例，该病例是三代人中的四名成员之一，患有外胚层发育不良，毛发、牙齿、指甲和汗腺受累程度各异。
