A 2-month-old girl was referred to the Department of Dermatology for the evaluation of extending hypopigmented skin lesions. At birth, she had multiple linear erythematous erosive skin defects, which became linear, hypopigmented patches with irregular border on the face, scalp, trunk, and both extremities (). We received the patient's consent form about publishing all photographic materials. The patient had a history of intrauterine growth retardation as a prenatal problem. There was no specific family history, and her two siblings were normal.\nThe patient also presented multiple congenital anomalies. Physical examination revealed patchy alopecia of the scalp, hypoplastic nails, and irregular gingiva with conical teeth. Ocular examination showed bilateral aniridia, moderate to severe microphthalmia, and unilateral corneal central opacity of the left eye (). The retinal vessels of both eyes were uncertain on fundus examination. Musculoskeletal examination revealed syndactyly of toes (), hypoplasia and clinodactyly of fingers, and coccyx deviation. Chromosomal analysis on peripheral blood lymphocytes showed normal karyotype (46, XX) (), and no mutation was found in IKBKG gene test. Therefore, the patient was diagnosed with HI with multiple congenital anomalies.\nTo manage the associated musculoskeletal anomalies, the patient was referred to the Department of Pediatric Orthopedic Surgery and underwent surgical treatment of toe syndactyly. For proper management of the other anomalies, she had been undergoing pediatric, ophthalmologic, and dermatological regular check-up.
Patient 6, a 20-year-old male with no noticeable familial cutaneous anomalies, was first referred for a diagnostic work-up regarding his cutaneous manifestations, which were diffuse, as patches, and primarily found on his left side. He had been first referred at age 3 years due to his severe psychomotor delay and for generalized tonic-clonic seizures. The EEG, at that age, revealed spike and wave discharges, prevalent in the frontal regions. Moderate cognitive delay was present. At his most recent physical examination, his stature was 175 cm (50th percentile): his left upper limb was 3 cm larger than the right, and the left lower limb 6 cm larger than the right. The left lower limb was 2.5 cm longer than the right. The ears were bilaterally large and cupped with an enlargement of the left hemiface. Mild right kyphoscoliosis was recorded. Brain MRI was normal. Skin biopsy was not performed.
