Juvenile xanthogranuloma with extra-cutaneous lesions--a case report

Area of Science:

• Pediatric Dermatology
• Histopathology
• Medical Case Reports

Background:

• Juvenile xanthogranuloma (JXG) is a rare, non-Langerhans cell histiocytosis primarily affecting infants and young children.
• JXG typically presents with cutaneous lesions but can involve extracutaneous sites, including the central nervous system, eyes, and liver.
• While often self-limiting, accurate diagnosis is crucial due to potential complications and the need to differentiate from other pediatric neoplasms.

Observation:

• This report details a rare case of congenital Juvenile xanthogranuloma presenting at birth.
• The case involved both cutaneous and potentially deep-seated lesions, necessitating thorough evaluation.
• Clinical and histopathological findings consistent with JXG were observed.

Findings:

• Congenital JXG, though rare, follows a similar clinical course to typical JXG, characterized by spontaneous regression.
• Histopathological examination confirmed the diagnosis, showing characteristic xanthogranuloma cells.
• The condition demonstrated a self-limiting course with regression over several months post-diagnosis.

Implications:

• Accurate and timely diagnosis of congenital JXG is essential for appropriate clinical management and parental reassurance.
• Understanding the self-limiting nature of JXG avoids unnecessary aggressive treatments.
• This case contributes to the literature on congenital presentations of JXG, aiding future diagnostic and therapeutic strategies.
