This clinical photograph shows the head and torso of a four-month-old infant, highlighting classic craniofacial dysmorphism associated with Trisomy 21 (Down Syndrome). Visible features include a prominent flat nasal bridge and a depressed nasal root, contributing to a flattened facial profile. The infant exhibits upslanting palpebral fissures (partially obscured for privacy) and a slightly protruding tongue (macroglossia or relative macroglossia). The head shape suggests a flat occiput, and the ears appear small and low-set. These phenotypic markers are key diagnostic indicators in pediatric genetics. The image serves as a clinical reference for identifying midface hypoplasia and other soft markers of chromosomal abnormalities during physical examination. The medical specialty is Pediatrics and Medical Genetics, intended for educational identification of syndromic facies.

Clinical photographs showing characteristic dysmorphic features associated with Trisomy 21 (Down syndrome). Panel A illustrates the palmar aspect of the left hand, highlighting a short and broad hand morphology, a single transverse palmar crease (simian crease), and clinodactyly (incurving) of the shortened fifth finger. Panel B shows the patient's foot from a dorsal view, demonstrating a prominent 'sandal gap' deformity, which is a widened space between the first (hallux) and second toes. These physical findings are classic phenotypic markers used in the clinical diagnosis of genetic trisomy. The images serve as educational visual aids for identifying common musculoskeletal and dermatoglyphic manifestations of chromosomal abnormalities during a physical examination.

Clinical photograph of an infant in the supine position displaying a complete cleft palate. The image focuses on the open oral cavity, where a significant midline defect is visible, extending from the hard palate anteriorly to the soft palate posteriorly, creating a direct communication with the nasal cavity. The infant presents with dysmorphic facial features consistent with Trisomy 21 (Down syndrome), including a flattened nasal bridge and almond-shaped, upward-slanting palpebral fissures (partially obscured). Medical interventions are visible, including an orogastric tube secured to the left cheek with adhesive tape and a thin medical probe or tongue depressor used to facilitate the examination of the oral defect. Neonatal teeth or tooth buds are visible on the upper alveolar ridge. The surrounding clinical context includes gloved hands of healthcare providers performing the physical examination. This image is an educational example of congenital craniofacial anomalies and their association with chromosomal syndromes.

This clinical photograph consists of frontal and lateral views of a newborn infant displaying multiple dysmorphic facial features. Key clinical findings include a broad forehead, ocular hypertelorism (increased distance between the eyes), and upward slanting palpebral fissures. A visible infraorbital crease is present beneath the eyes. The nasal anatomy shows a depressed nasal bridge. Midface examination reveals a flat philtrum and micrognathia (small jaw). The lateral view highlights low-set, malformed ears with attached pinnae and a short, webbed neck. These features are characteristic of chromosomal abnormalities, specifically consistent with the phenotype of Trisomy 21 (Down syndrome). The infant is shown in a clinical setting with ECG monitoring leads visible on the chest. This image serves as an educational reference for neonatal physical examination and the identification of genetic dysmorphism in pediatrics and medical genetics.
