Insights
Idiopathic palmoplantar eccrine hidradenitis (IPPH) is a painful foot condition in children, often triggered by physical activity. This benign disorder typically resolves on its own with rest, requiring no specific medical treatment.
Area of Science:
- Dermatology
- Pediatrics
Background:
- Idiopathic palmoplantar eccrine hidradenitis (IPPH) is a recently identified skin condition affecting the feet.
- It is characterized by painful, red nodules on the soles.
Observation:
- Five cases of IPPH in healthy children are presented.
- The condition often arises after strenuous physical activity.
- A neutrophilic infiltrate was observed around eccrine sweat glands.
Findings:
- IPPH presents as painful erythematous plantar nodules.
- The disorder is benign and self-limiting.
- Complete rest led to symptom resolution without medical intervention.
Implications:
- IPPH may be more prevalent than currently reported.
- Awareness among pediatricians can prevent unnecessary diagnostic procedures and treatments.
- This condition highlights the importance of considering physical activity as a trigger for pediatric foot conditions.
Abstract:
Idiopathic palmoplantar eccrine hidradenitis (IPPH) is a recently described disorder characterized by painful erythematous plantar nodules and in three cases, showed a typical neutrophilic infiltrate around and within the eccrine sweat apparatus. Five cases of IPPH on the soles of the feet in healthy children are reported. The disorder presented after intense physical activity in four cases. The course was benign and self-limiting. Complete bed rest for several days without any medical therapy led to alleviation of the pain and disappearance of all the lesions. Conclusion. Idiopathic palmoplantar eccrine hidradenitis may be more common than reported. Paediatricians should be aware of it in order to avoid unnecessary diagnostic tests and treatments.
