Cutis verticis gyrata associated with congenital heart disease.

Cutis verticis gyrata (CVG) is a very rare benign disorder characterised by convoluted folds and deep furrows of the scalp that mimic cerebral sulci and gyri. Associations with other pathologies as neuropsychiatric and/or ophthalmologic disorders, secondary cases to inflammatory or neoplastic processes, as well as cases associated to genetic disorders as Turner's syndrome have been reported, but there is no literature describing an association with a congenital structural heart defect and no other underlying condition. We report a case of primary CVG in a 3-week-old female infant associated with an echocardiographic diagnosis of cor triatriatum. Other systemic examination findings and investigations were unremarkable, and the patient has normal neurodevelopment at 1 year old. Aside from the neuropsychiatric and ophthalmologic pathologies commonly associated with primary non-essential CVG, it should be noted that isolated congenital cardiac lesions are also possible, so as to increase our index of suspicion in patients with the disorder.

Clinical insights from an unusual Turner syndrome manifestation: Congenital cutis verticis gyrata.

Cutis verticis gyrata (CVG) is classified as primary or secondary according to the absence or presence of underlying soft tissue abnormalities. We report an infant with Turner syndrome (TS) who in addition presented with CVG on the scalp. The skin biopsy revealed a hamartoma-like lesion. We reviewed the clinical and histopathological findings of the 13 reported cases of congenital CVG in patients with TS, including ours. In 11 of them, CVG was localized on the skin of the scalp, mainly on the parietal region, and in two, on the forehead. Clinically, CVG had a flesh-colored aspect, with absent or sparse hair, and was not progressive. CVG was classified as primary in four patients who had skin biopsy and it was attributed to the intrauterine lymphedema of TS. However, histopathology in two of these patients identified dermal hamartoma as a secondary cause of CVG, and in three others, including ours, there were hamartomatous changes. Although further studies are required, previous findings support the proposal that some CVG may instead be dermal hamartomas. This report alerts clinicians to recognize CVG as a low-frequency manifestation of TS, but also to consider the possible co-occurrence of TS in all female infants with CVG.

A Novel Forkhead Box L2 Missense Mutation, c.1068G>C, in a Chinese Family With Blepharophimosis/Ptosis/ Epicanthus Inversus Syndrome.

ABSTRACT: The aim of the study was to report a novel forkhead box L2 (FOXL2) missense mutation in a Chinese blepharophimosis/ ptosis/epicanthus inversus syndrome family. Three generations of the Chinese family with blepharophimosis/ptosis/epicanthus inversus syndrome were enrolled in this study. Blood samples from patients of this family were collected and then analyzed by whole-exome sequencing. Confocal microscopy was performed to detect the subcellular location of FOXL2. Transactivation studies were performed and verified with real time polymerase chain reaction. A novel mutation (c.1068G>C) located in the downstream of deoxyribonucleic acid-binding forkhead domain was identified. Confocal photos showed the novel mutation did not disturb FOXL2 function, and the mutant protein could still transactivate steroidogenic acute regulatory protein, a key regulator of primary ovarian failure (POF). Our study revealed a novel missense mutation (c.1068G>C) and expanded the spectrum of FOXL2 gene mutations.

Oculocerebrocutaneous syndrome (Delleman Oorthuys syndrome) associated with congenital glaucoma: A case report.

INTRODUCTION: Oculocerebrocutaneous syndrome (Delleman Oorthuys syndrome) (OMIM 164180) is a rare syndrome affecting eyes, skin, and central nervous system, and it is usually associated with microphthalmia. CASE DESCRIPTION: A 4-day old baby boy was referred to our hospital for the evaluation of buphthalmos in the left eye. His clinical evaluation was remarkable for oculocerebrocutaneous syndrome with congenital glaucoma in the left eye and microphthalmos in the right eye. CONCLUSION: Our report represents the first case of oculocerebrocutaneous syndrome associated with unilateral congenital glaucoma so far in the literature.

Dysfunction of dermal initial lymphatics of the arm and upper body quadrant causes congenital arm lymphedema.

OBJECTIVE: The objective of this study was to explore the pathologic process underlying primary lymphedema. METHODS: Twenty-seven patients with unilateral congenital arm lymphedema who visited our clinic from January 1, 2014, to May 30, 2019, were enrolled. The patients' clinical signs and the findings of indocyanine green (ICG) lymphography, skin tissue immunohistochemical staining, and whole exome sequencing of tissue and blood were evaluated. RESULTS: Among the 27 patients, 11 were diagnosed with stage II and 16 were diagnosed with stage III lymphedema. No lymphatic vessels were visualized in the affected arm in 25 of 27 (93%) patients who underwent ICG lymphography; likewise, no lymphatics were found in the territories of axillary lymph node drainage in the trunk, irrespective of any anomalies of the axillary lymph nodes. In only two (7%) patients, an unclear lymphatic trunk gradually appeared in the dorsum of the affected hand. The number of initial lymphatics was increased in the skin specimens of all nine patients in whom lymphatics were not demonstrated by ICG lymphography. Among 14 tested patients, we found compound heterozygote variants in the PIEZO1 gene in only one (7%) patient. Two missense variants, c.4072C>T; p.Arg1358Cys and c.5033C>T; p. Ala1678Val, were identified and found to have been inherited from the father and mother, respectively. No other pathogenic or likely pathogenic variants of currently known lymphedema-related genes were identified in the remaining 13 patients. No genetic difference was found between the lymphedematous and nonedematous healthy skin tissue of the same person. CONCLUSIONS: Segmental or regional dysfunction of the dermal initial lymphatics causes congenital arm lymphedema and may have implications for clinical treatment.

A rare association of blepharophimosis-ptosis-epicanthus inversus case with congenital nasolacrimal duct obstruction.

PURPOSE: The aim of reporting this case is to describe a rare combination of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction. A variety of lacrimal anomalies have been seen in blepharophimosis-ptosis-epicanthus inversus syndrome but the occurrence of nasolacrimal duct obstruction is rare. METHOD: The blepharophimosis-ptosis-epicanthus inversus syndrome is an autosomal dominant rare genetic defect with clinical manifestation of dysplasia of the eyelids, palpebral fissures, flat nasal bridge, and ptosis. A 20-month-old boy was referred with the complaints of watering and discharge from his right eyes since birth. On examination, the child had all the features of blepharophimosis-ptosis-epicanthus inversus syndrome with right congenital nasolacrimal duct obstruction in line with the published reports. RESULT: On endoscopic probing and irrigation, the probe could not be visualized into the inferior meatus. On dacryoendoscopy, the membranous part of the nasolacrimal duct was found to be completely obliterated with no light transmission into the nose indicating a malformed nasolacrimal duct. The child was managed by endoscopic dacryocystorhinostomy. We could find only one case report published so far on the combination of congenital nasolacrimal duct obstruction with blepharophimosis-ptosis-epicanthus inversus syndrome. This study adds one more case of blepharophimosis-ptosis-epicanthus inversus syndrome with congenital nasolacrimal duct obstruction and adjuvant use of dacryoendoscopy.

Self-improving dystrophic epidermolysis bullosa: First report of clinical, molecular, and genetic characterization of five patients from Southeast Asia.

Self-improving dystrophic epidermolysis bullosa is a rare subtype of dystrophic epidermolysis bullosa (DEB) characterized by significant improvement in skin fragility within the first few years of life. Genetic inheritance has previously been reported as autosomal dominant or recessive with both forms harboring mutations in COL7A1. To date, there have been no reports of this rare clinical entity from various Southeast Asian ethnicities. Here, we describe the clinical and molecular features of five patients from the Southeast Asia region who presented with predominantly acral-distributed blisters and erosions in the first few days of life. Blistering resolved over several months, without appearance of new blisters. By immunofluorescence, intraepidermal retention of Type VII collagen was observed in all patient skin biopsies when investigated with antibody staining. Genetic analysis of four patients revealed pathogenic variants in COL7A1 which have not been previously reported. The clinical diagnosis in these rare patients is confirmed with molecular histology and genetic characterization.

Bilateral cervical chondrocutaneous branchial remnants: A case report and a review of the literature.

RATIONALE: Cervical chondrocutaneous branchial remnants are rare, benign, congenital anomalies, frequently seen bilaterally. PATIENT CONCERNS: Here, we report the case of a 4-month-old female infant who presented with bilateral lower neck skin tag since birth. DIAGNOSIS AND INTERVENTIONS: The patient underwent mass excision. The final pathological diagnosis was bilateral cervical chondrocutaneous branchial remnants with hyaline cartilage. OUTCOMES: No complications were observed after excision. One-year follow-up revealed no recurrence. LESSONS: Bilateral chondrocutaneous branchial remnants are rare anomalies. They are often associated with cardiac or genitourinary abnormalities. Therefore, additional preoperative imaging of the abdomen and heart are recommended.

Incidence of Occult Spinal Dysraphism Among Infants With Cutaneous Stigmata and Proportion Managed With Neurosurgery: A Systematic Review and Meta-analysis.

Importance: Occult spinal dysraphism (OSD) is the most common congenital spinal anomaly. Cutaneous anomalies such as skin dimples or deviated gluteal folds are well known as stigmata of OSD and are indicators for further evaluation; however, the association between cutaneous anomalies and OSD has not been systemically evaluated. Objective: To evaluate the incidence of OSD and the proportion of OSD cases managed with a neurosurgical intervention among neonates or infants with various cutaneous stigmata. Data Sources: PubMed and Embase databases were searched for studies published up to July 25, 2018, that evaluated the proportion of OSD cases in neonates or infants with cutaneous stigmata. Search terms included ultrasound, dysraphism, dimple, and infant or neonate. The search was limited to English-language publications. Study Selection: Two reviewers selected the studies evaluating the incidence of OSD among neonates or infants with cutaneous stigmata. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for data extraction were followed. Pooled proportions of OSD cases and OSD cases that were managed with a neurosurgical intervention were obtained using the generalized linear mixed model and maximum likelihood method. Main Outcome and Measures: The pooled incidence of OSD and OSD cases managed with neurological surgery among patients with cutaneous stigmata was the primary outcome. This outcome was also evaluated in each subgroup, and heterogeneity was explored using subgroup analysis. Results: A total of 15 studies, involving 6558 neonate or infant patients with various cutaneous stigmata, were included. The pooled proportion of OSD cases among the patients with cutaneous stigmata was 2.8% (95% CI, 2.1%-3.8%; I2 = 51.6%), and the proportion managed with neurological surgery was 0.6% (95% CI, 0.3%-1.3%; I2 = 66.4%). Cases with combined stigmata showed a significantly higher association with OSD than those with a single stigma (10.5% [95% CI, 6.9%-15.8%] vs 2.3% [%, 95% CI, 1.5%-3.5%]; P < .001). The pooled proportion of OSD cases among patients with an atypical dimple was significantly higher than among those with simple dimple (8.8% [95% CI, 4.5%-16.6%] vs 0.6% [95% CI of 1.4%-2.1%]; P = .001). Conclusions and Relevance: The proportion of OSD in healthy, asymptomatic patients with midline cutaneous stigmata was low, and the proportion of patients who underwent a neurosurgical intervention was even lower. However, a careful evaluation as well as potential spinal magnetic resonance imaging is recommended for neonates or infants with combined stigmata or an atypical dimple for possible high-risk lesions.

Clarifying Misleading Lumps and Sinuses in the Newborn.

Neonates often have congenital lumps or sinuses. It is expected that pediatricians will distinguish those with important physiologic implications from those without. Accurate understanding of these lesions is important for the practitioner to avoid unnecessary tests and anxiety and to ensure that seemingly benign lesions with important implications are addressed in a timely manner. This review aims to clarify the consequences of some lesions that can easily be misinterpreted, offering guidance in the initial management of patients with congenital lumps or sinuses. We address several lesions that can easily be misconstrued, including wattles, preauricular lesions, sacral sinuses, second branchial cleft anomalies, torticollis, and dermoid cysts.

Wiedemann-steiner syndrome with a de novo mutation in KMT2A: A case report.

RATIONALE: Wiedemann-Steiner syndrome (WDSTS, online mendelian inheritance in man 605130) is a rare autosomal dominant disorder characterized by hypertrichosis cubiti. Here, we report a Chinese boy who do not show the characteristic of hypertrichosis cubiti, and was misdiagnosed as blepharophimosis-ptosis-epicanthus inversus syndrome at first. We found a de novo frameshift mutation (p.Glu390Lysfs*10) in the KMT2A gene, which was not reported before. Our study increases the cohort of Chinese WDSTS patients, and expand the WDSTS phenotypic and variation spectrum. PATIENT CONCERNS: The patient demonstrated typical craniofacial features of blepharophimosis-ptosis-epicanthus inversus syndrome, including small palpebral fissures, ptosis, telecanthus, and epicanthus inversus, besides he had congenital heart disease (ventricular septal defects), strabismus, hypotonia, amblyopia, delayed speech and language development, delayed psychomotor development, and amblyopia (HP:0000646) which was not reported before. DIAGNOSIS: FOXL2 gene was cloned and sequenced, however, there was no mutation detected in this patient. The result of Chromosomal microarray analysis was normal. The patient was diagnosed as WDSTS by whole exome sequencing. INTERVENTIONS: The patient received cardiac surgery, frontalis suspension and regular speech and occupational therapy. He also treated with growth hormone (GH). OUTCOMES: The patient's symptoms are improved after cardiac surgery and frontalis suspension, he can express himself well now and had a 10 cm gain in height. LESSONS: As the relationship between genotype and phenotype becomes more and more clear, WES is incredibly powerful tool to diagnose the disease of WDSTS.

[Cutaneous signs of occult cranial and spinal dysraphism]. / Signes cutanés des dysraphies occultes cranioencéphaliques et spinales.

Dysraphism refers to neural tube closure abnormalities and midline closure abnormalities of the skin, paravertebral muscles, vertebrae and meninges. Cranial dysraphism (CD) and occult spinal dysraphism (OSD) may be discovered via evocative skin signs present at birth or appearing later in childhood or even in adulthood. This review describes the various types of skin signs associated with CD and OSD. All congenital midline skin lesions, particularly on the frontonasal area, the vertex or the occipitocervical and low back regions, should prompt suspicion of underlying dysraphism. The main evocative midline skin abnormalities are: (i) for underlying DCEO: a nodule, swelling, skin openings and hair collar sign or hair tuft; (ii) for underlying DSO, localized hypertrichosis, an atypical or complex lower back dimple, a dermoid fistula, infantile haemangioma, caudal appendage and lipoma. In the event of suspected DCEO or DSO, spinal or medullary MRI constitutes the reference examination.

Successful treatment of late-onset nevus comedonicus with Er:YAG laser.

Nevus comedonicus, a rare congenital hamartoma of the pilosebaceous unit, is characterized by keratotic plugging. It usually occurs after birth and during early childhood. It rarely appears in adulthood. Despite the benign nature of the condition, it usually requires treatment due to aesthetic reasons. Several treatments have been reported in nevus comedonicus, most of them resulting with recurrences. Here, we report a case of nevus comedonicus with adult onset, successfully treated with erbium-doped yttrium aluminum garnet (Er:YAG) laser therapy.

Oskar Kobylinski (1856-1926) and the first description of Noonan syndrome in the medical literature.

While a student of University in Dorpat (now Tartu, Estonia) Oskar Kobylinski published an article reporting on his 22-year-old patient Leisar Eischikmann, who suffered from a congenital deformity of the neck. Kobylinski described this rare anomaly and called it "flüghautige Verbreitung des Halses" (wing-like extension of the neck). It was only in 1902 when the name pterygium colli was introduced, and it has been in use ever since. This malformation is part of some congenital syndromes, most prominently, Turner syndrome and, more rarely, of Noonan syndrome. As Opitz et al. pointed out, the patient described in the 1883 article from Archiv für Anthropologie is probably the first person with Noonan syndrome to have been pictured in the medical literature. The article was signed only by "O. v. Kobylinski, student of medicine." Further archival research was needed to identify this physician and provide more details about his unusual career.
