Summary
This rare skin condition, eccrine angiomatous hamartoma, presented atypically on an infant's abdomen. Delayed diagnosis was confirmed by later-onset hyperhidrosis, highlighting the importance of clinical-pathological correlation.
Area of Science:
- Dermatology
- Pathology
- Pediatrics
Background:
- Eccrine angiomatous hamartoma (EAH) is a rare congenital skin condition with both vascular and sudoral elements.
- Fewer than thirty cases have been documented globally, making it an uncommon diagnosis.
Observation:
- A 3.5-month-old female infant presented with a painful abdominal plaque, noted shortly after birth.
- Initial biopsies were inconclusive, but a 15-year follow-up revealed localized hyperhidrosis, confirming the EAH diagnosis.
- This represents the first reported abdominal case, contrasting with the typical limb presentation.
Findings:
- Histological examination revealed numerous dermal vessels and eccrine glands.
- Complete surgical excision was not achieved.
- The hamartoma showed no progression over 15 years, and associated pain gradually resolved.
Implications:
- Congenital EAH can present with delayed diagnosis, emphasizing the need for thorough clinical and pathological correlation.
- Localized hyperhidrosis can be a key diagnostic indicator for EAH.
- Abdominal EAH is rare, with most cases reported on the limbs.
