Abstract:
A 3-month-old infant with scleredema had associated cytomegalovirus pneumonia with a rapidly fatal course. Because differentiation of scleredema from scleredema neonatorum, subcutaneous fat necrosis, and scleroderma may be difficult, histologic diagnosis is important. Cetylpyridinium chloride was used successfully as a fixative to demonstrate acid mucopolysaccharides histologically.
Insights
Scleredema in an infant, linked to cytomegalovirus pneumonia, proved rapidly fatal. Histologic diagnosis is crucial for differentiating scleredema from similar conditions, with cetylpyridinium chloride aiding in visualizing acid mucopolysaccharides.
Area of Science:
- Pediatric Pathology
- Dermatopathology
- Infectious Diseases
Background:
- Scleredema is a rare, indurative skin condition affecting connective tissue.
- Distinguishing scleredema from similar pediatric dermatoses like scleredema neonatorum, subcutaneous fat necrosis, and scleroderma can be challenging.
- Cytomegalovirus (CMV) infections can present with diverse clinical manifestations in infants.
Observation:
- A 3-month-old infant presented with scleredema.
- The infant also had cytomegalovirus pneumonia.
- The clinical course was rapidly fatal.
Findings:
- Histologic examination is essential for accurate diagnosis of scleredema.
- Cetylpyridinium chloride proved effective as a histological fixative.
- This fixative facilitated the demonstration of acid mucopolysaccharides in the affected tissue.
Implications:
- Accurate histologic diagnosis is critical for managing infants with scleredema and associated infections.
- The use of cetylpyridinium chloride offers a reliable method for identifying key histological features.
- This case highlights the severe potential of combined scleredema and CMV pneumonia in neonates.
