Insights
Lymphoplasmocytic plaque in children (LPC) is a rare pediatric skin condition. This case highlights a rare arm location and treatment response in a 10-year-old boy.
Area of Science:
- Dermatology
- Pediatric Pathology
Background:
- Lymphoplasmocytic plaque in children (LPC) is a rare skin disorder.
- It is characterized by dense dermal infiltration of lymphocytes and plasma cells.
- Accurate diagnosis and management are essential for affected pediatric patients.
Observation:
- A 10-year-old male presented with LPC on the extensor surface of his upper arm.
- This location is rarely reported for this condition.
- The patient received treatment with topical and intralesional corticosteroids.
Findings:
- Histopathological examination confirmed the diagnosis of lymphoplasmocytic plaque.
- The patient exhibited a partial improvement following corticosteroid therapy.
- The case underscores the variability in clinical presentation and treatment response.
Implications:
- This case expands the understanding of LPC's clinical spectrum.
- It emphasizes the importance of considering LPC in pediatric patients with unusual skin lesions.
- Further research may elucidate optimal treatment strategies for pediatric lymphoplasmocytic plaque.
Abstract:
Lymphoplasmocytic plaque in children (LPC) is a rare and distinctive skin disorder primarily affecting the pediatric population. Characterized by its unique histopathological features, the condition manifests as well-defined plaques with a predominance of lymphocytes and plasma cells infiltrating the dermis. Despite its limited prevalence, recognizing this entity is crucial for accurate diagnosis and appropriate management of affected patients. We report the case of a 10-year-old male presenting with LPC in the extensor surface of the upper arm, a rarely reported location, treated with both topical and intralesional corticosteroids resulting in partial improvement.
