Summary
This case study presents benign cephalic histiocytosis in an infant, a rare skin condition. Diagnosis was confirmed via histopathology and immunohistochemistry, identifying it as non-Langerhans cell histiocytosis.
Area of Science:
- Dermatology
- Pediatric Pathology
- Histiocytosis
Background:
- Benign cephalic histiocytosis is a rare, self-limiting disorder affecting infants.
- It typically presents as multiple papules on the face.
Observation:
- A 15-month-old boy presented with bilateral malar papules.
- No other systemic or cutaneous manifestations were noted.
Findings:
- Histopathology showed a papillary dermal pattern.
- Immunohistochemistry was negative for S100 and CD1a, but positive for CD68.
- These findings confirmed a diagnosis of non-Langerhans cell histiocytosis.
Implications:
- This case highlights the importance of accurate histopathological and immunohistochemical evaluation for diagnosing non-Langerhans cell histiocytosis.
- Understanding these features aids in differentiating it from other histiocytic disorders in pediatric patients.
