PHACES syndrome is an acronym for the syndromic presentation of Posterior fossa malformation, Hemangioma, Arterial anomalies, Coarctation of aorta/cardiac defects, Eye abnormalities and Sternal malformations. Infantile hemangiomas are the most common tumors of infancy. Regional odontodysplasia, commonly referred to as \"ghost teeth\", is a rare localized developmental malformation of enamel and dentin with varying levels of severity that results in unusual clinical and radiographic appearances of affected teeth. This report describes a rare case of a two-year-old Caucasian male diagnosed with PHACES syndrome also presenting with multi-regional odontodysplasia. Ten of twenty teeth were dysplastic. The patient was treated under general anesthesia in a hospital setting. All affected primary teeth were extracted due to sensitivity, abscess and extremely poor long-term prognosis. Moving forward, a long-term interdisciplinary approach will be necessary to address this child\'s dentition as it develops.

BACKGROUND: Joubert syndrome (JS) is a rare genetic disorder that presents with various neurological symptoms, primarily involving central nervous system dysfunction. Considering the etiology of JS, peripheral nervous system abnormalities cannot be excluded; however, cases of JS accompanied by peripheral nervous system abnormalities have not yet been reported. Distinct radiological findings on brain magnetic resonance imaging were considered essential for the diagnosis of JS. However, recently, cases of JS with normal or nearly normal brain morphology have been reported. To date, there is no consensus on the most appropriate diagnostic method for JS when imaging-based diagnostic approach is challenging. This report describes the case of an adult patient who exhibited bilateral peroneal neuropathies and was finally diagnosed with JS through genetic testing.
METHODS: A 27-year-old man visited our outpatient clinic due to a gait disturbance that started at a very young age. The patient exhibited difficulty maintaining balance, especially when walking slowly. Oculomotor apraxia was observed on ophthalmic evaluation. During diagnostic workups, including brain imaging and direct DNA sequencing, no conclusive findings were detected. Only nerve conduction studies revealed profound bilateral peroneal neuropathies. We performed whole genome sequencing to obtain a proper diagnosis and identify the gene mutation responsible for JS.
CONCLUSIONS: This case represents the first instance of peripheral nerve dysfunction in JS. Further research is needed to explore the association between JS and peripheral nervous system abnormalities. Detailed genetic testing may serve as a valuable tool for diagnosing JS when no prominent abnormalities are detected in brain imaging studies.

BACKGROUND: Zhu-Tokita-Takenouchi-Kim syndrome (ZTTK syndrome) is a severe multi-systemic developmental disorder, caused by variants in the SON gene. A patient diagnosed with ZTTK syndrome who carried a de novo SON mutation and exhibited recurrent myocardial injury was described in this case.
METHODS: A 7-year-old girl was admitted to the Cardiology Department of Beijing Children\'s Hospital in November 2019 due to myocardial injury following respiratory infection. She displayed elevated myocardial enzymes and severe T-wave changes on electrocardiogram. Over the past three years, she had experienced myocardial injury on three occasions. Additionally, she exhibited intellectual disability, congenital amblyopia, and dysmorphic facial features. Genetic analysis revealed a de novo heterozygous mutation c.3852_3856delGGTAT in the SON gene, which was confirmed by Sanger sequencing of her parents. She received anti-infection treatment and was administered metoprolol orally. Her condition was stable at the time of discharge. Over a 42-month follow-up period at the outpatient clinic, she complained intermittent fatigue and palpitation.
CONCLUSIONS: The identified SON mutation, which plays a crucial role in heart development and mitochondrial function, may be associated with an increased susceptibility to myocardial injury or cardiomyopathy. This case report contributes novel insights into this rare condition and suggests the expansion of the ZTTK syndrome phenotype.

Bosma arhinia microphthalmia syndrome (BAMS) is a rare syndrome consisting of several craniofacial abnormalities, including congenital arhinia. In this case report, the authors present the first case of a patient with BAMS and dacryocystocele who successfully underwent dacryocystectomy. Dacryocystectomy may serve as a viable surgical approach for dacryocystocele in patients with abnormal nasal anatomy. [J Pediatr Ophthalmol Strabismus. 2024;61(3):e16-e18.].

Optic disc pits are hypothesized to form because of failure of embryonic fissure closure, which can also present with congenital defects in the choroid, RPE, and neurosensory retina. It is also associated with serous macular detachment. We present a case report of a 32-year-old man with an optic disc pit and independent choroidal coloboma below the inferior peripapillary area in the left eye, associated with macular retinoschisis with serous detachment.

BACKGROUND: Double optic disc pit maculopathy is a rare entity. It can be difficult to manage because of excessive leakage and chronic maculopathy.
OBJECTIVE: To describe surgical management in a case of double optic disc pits with maculopathy.
CONCLUSIONS: A 42-year-old male presented with double optic disc pits with macular detachment in the left eye. The best-corrected visual acuity (BCVA) was 20/60, N12. Preoperative OCT showed the presence of two disc pits. The macular region had large retinoschisis and subretinal fluid (SRF) with a central foveal thickness of 879 microns and loss of the ellipsoid zone. A shallow communication from the temporal aspect of the disc to the submacular area was also noted. Among the options of observation, laser photocoagulation, and surgery, the patient opted for surgical management.
METHODS: A standard-3 port 23-gauge pars plana vitrectomy was done. After staining the ILM with brilliant blue, ILM peeling was done with the help of forceps and Finesse loop. ILM flaps were inverted over to cover the optic disc pits and sealed with a drop of fibrin glue. Next, 20% SF6 gas was used for tamponade. Pre- and post-surgery parameters such as visual acuity and OCT were evaluated.
UNASSIGNED: After 6 weeks, left eye BCVA was 20/40 with OCT showing reduced SRF and reduced intraretinal schisis with a foveal thickness of 546 microns. At 3 months of follow-up, the vision in the left eye had improved to 20/30 with further reduction in the retinoschisis and foveal thickness of 482 microns.
CONCLUSIONS: In this interesting case, we demonstrate a unique way of sealing the defect surgically by vitrectomy and inverted ILM flap with fibrin glue over the disc pits. Despite sealing the maculopathy is slow to resolve.

Ocular colobomas are typically located in the inferonasal quadrant and attributable to defective fetal fissure closure. Colobomas can, however, affect any part of the eye, from the eyelid to the optic nerve. We present the case of a 7-year-old girl with two retinochoroidal colobomas in an atypical temporal location, with associated other ocular defects.

BACKGROUND: Oculo-facio-cardio-dental (OFCD) syndrome is a rare condition that affects the eyes, face, heart, and teeth of patients. One notable dental characteristic of OFCD is radiculomegaly, or root gigantism, which highlights the role of dentists in detecting this syndrome. OFCD is an X-linked dominant syndrome that results from a variant in the BCOR gene. Our study presents the first documented case of OFCD in Vietnam and reports a novel BCOR gene variant observed in this case.
METHODS: A 19-year-old Vietnamese female patient with an extremely long root with an abscess was clinically examined for the expression of OFCDs. The radiograph and the variant in BCOR gene were also evaluated. We identified abnormalities in the teeth, as well as ocular, facial, and cardiac features, with radiculomegaly of the canines being a specific symptom for OFCDs. The patient\'s genetic analysis revealed a pathogenic heterozygous deletion at intron 11 of the BCOR gene, representing a novel variant.
CONCLUSIONS: Oculo-facio-cardio-dental syndrome (OFCD) is an extremely rare condition characterized by abnormalities in the eyes, face, heart, and teeth, often caused by variants in the BCOR gene. Radiculomegaly, or enlarged dental roots, is a key diagnostic feature of OFCD, and early detection is crucial for preventing future dental complications.

BACKGROUND: Joubert syndrome is a rare disease of genetic origin with autosomal recessive inheritance and extreme genetic heterogeneity with more than 40 causative genes. Joubert syndrome 7 is caused by mutations in the RPGRIP1L gene.
METHODS: Our report describes a pediatric patient with clinical features compatible with JS type 7 such as hypotonia, developmental delay and aplasia of the cerebellar vermis.
METHODS: The clinical features and the MRI of the head and neck which showed alterations at the level of the posterior fossa, with absence of the vermis and horizontal disposition of the cerebellar peduncles, were compatible with Joubert syndrome. Whole exome sequencing detected the variants RPGRIP1L (NM_015272.2) c.697A > T (p. Lys233Ter) and RPGRIP1L (NM_015272.2) c.3545 del (p.Pro1182LeufsTer25).
METHODS: Resection was performed to correct the polydactyly. At age 2 years umbilical hernia, adenoid surgery and ventilatory tubes surgery were performed. Renal biopsy confirmed interstitial fibrosis and focally accentuated mild tubular atrophy with focal tubular hypertrophy, compatible with the clinical suspicion of Joubert syndrome. Congenital hip dislocation surgery was performed. The patient underwent surgery for correction of concomitant divergent strabismus and continued with glasses for astigmatism and hyperopia.
RESULTS: Sanger sequencing confirmed the patient´s results and the father was found to be a carrier of RPGRIP1L (NM_015272.2) c.697A > T (p. Lys233Ter) and the mother and maternal grandmother as carriers of RPGRIP1L (NM_015272.2) c.3545del (p.Pro1182LeufsTer25). RPGRIP1L:c.3545del novel variant is a deletion which changes the reading frame, altering the RPGR1_C terminal domain and giving rise to an incomplete protein whose functions will be altered.
CONCLUSIONS: This is the first genetically confirmed case of JS in Colombia, the first carrier of biallelic RPGRIP1L gene mutations with hip dislocation and incomplete glottic closure and the first report of the novel c.3545del likely pathogenic variant causing JS.
