Clinical photograph of a 3-year-old child illustrating the early phenotypic manifestations of Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome. The image focuses on the patient's head and upper torso, demonstrating mild coarsening of facial features characteristic of lysosomal storage disorders. Key visual findings include a slightly flattened midface with a depressed nasal bridge, full and rounded cheeks, and thickened lips, particularly the upper lip. The hair appears somewhat coarse and dark. The eyes are obscured for patient privacy. This clinical visual serves as an educational tool for medical professionals to recognize subtle facial dysmorphism that precedes the more severe somatic and neurological symptoms of MPS II. The identification of such features at an early age is critical for timely diagnostic intervention and metabolic evaluation in pediatric populations.

This clinical photograph displays a fundus view of the retina, identifying key diagnostic features associated with retinitis pigmentosa in a patient with Mucopolysaccharidosis Type II (MPS II or Hunter Syndrome). The image shows a well-defined optic disc with clear margins. The retinal vasculature exhibits significant attenuation, with thinning of both the arterioles and venules as they radiate toward the periphery. Centrally, the macula demonstrates a pigmented lesion and areas of atrophy, indicating macular involvement. The background retina reveals uneven pigmentation with a granular appearance, characteristic of tapetoretinal degeneration. These visual findings provide clinical evidence of retinopathy, which is a significant posterior chamber manifestation of MPS II, leading to nyctalopia and progressive visual field loss. The imaging is essential for ophthalmologists monitoring metabolic disorders where glycosaminoglycan (GAG) deposition can impact ocular structures.

This clinical photograph of a pediatric patient demonstrates the classic 'coarse facial features' characteristic of mucopolysaccharidosis (MPS), specifically Hunter syndrome (MPS II). The visible dysmorphic features include a broad, flattened nasal bridge and a wide nasal tip. There is significant mid-face fullness with large, rounded cheeks and a prominent forehead. The lips are notably thickened (macrocheilia), and the patient exhibits a wide smile that reveals slightly irregular dental spacing. The overall facial contour is rounded with a lack of sharp definition, typical of the storage-related soft tissue and bony changes seen in lysosomal storage disorders. The ears appear slightly low-set. This image serves as a teaching tool for recognizing the phenotypic manifestations of metabolic diseases involving glycosaminoglycan accumulation.

A series of three longitudinal clinical photographs (A, B, C) documenting the progressive facial phenotype of a female patient with Mucopolysaccharidosis type II (MPS II), or Hunter syndrome. Image A shows the patient as an infant with subtle facial features. Image B depicts the patient as a toddler, where a transition toward coarser facial features begins to emerge. Image C shows the patient at the time of presentation with the classic 'coarse' facies characteristic of severe MPS II. Visible features include a thickened, prominent forehead, a flattened nasal bridge with a broad nose, full lips, and macroglossia. Notable dental findings in image C include widely spaced, peg-shaped teeth and gingival hypertrophy. The hair appears progressively coarser and thicker throughout the timeline. This progression illustrates the metabolic accumulation of glycosaminoglycans (GAGs) in connective tissues, leading to the distinctive dysmorphic features used in the clinical diagnosis of lysosomal storage diseases.
