Insights
Therapy-resistant diaper dermatitis in infants can signal a rare but serious condition, Langerhans cell histiocytosis (LCH). Early recognition of this skin manifestation is crucial for timely diagnosis and management of LCH.
Area of Science:
- Pediatric Dermatology
- Oncology
- Immunology
Background:
- Diaper dermatitis is a common pediatric skin condition, typically benign and easily treated.
- Causes include irritation, fungal infections (Candida), or eczema.
- Persistent or unusual cases warrant further investigation.
Observation:
- A 14-month-old girl presented with persistent diaper dermatitis.
- Additional symptoms included scalp abnormalities, fever, otorrhea, and widespread lymphadenopathy.
- Diagnosis was delayed despite multiple medical consultations.
Findings:
- Skin biopsies confirmed Langerhans cell histiocytosis (LCH).
- LCH is a rare clonal proliferative disorder of Langerhans cells.
- Cutaneous manifestations, like diaper dermatitis, can be the initial diagnostic clue for LCH.
Implications:
- Diaper dermatitis is not always benign; it can be an early sign of LCH.
- Recognizing therapy-resistant diaper dermatitis is vital for diagnosing rare conditions.
- This case highlights the importance of considering systemic diseases in persistent pediatric skin conditions.
Background:
Diaper dermatitis in children is common and usually harmless. Often the cause is irritation, a secondary candida infection or eczema, for which treatment is simple and effective. In this paper we show that a therapy resistant diaper dermatitis can be the diagnostic clue to the rare but important diagnosis Langerhans cell histiocytosis (LCH).
Case Description:
We saw a 14 months old girl with therapy resistant diaper dermatitis, skin abnormalities on the hairy scalp, fever, otorrhea and extensive lymphadenopathy. After a long period of doctor visits, skin biopsies confirmed the diagnosis of LCH.
Conclusion:
LCH is a rare condition that often manifests in the skin. LCH can manifest in different organs. Although skin involvement is sometimes considered as less relevant, cutaneous manifestations can be an important diagnostic clue. In this paper we show that diaper dermatitis is not always harmless: it can be a symptom of LCH.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
