Reticular Pigmentary Anomalies in Pediatrics

Maria Isabel Pastura — 2025-03-07

Reticular pigmentary anomalies in childhood consists of different entities that clinically present with a common factor of a hyperpigmented reticular skin pattern. This is why they are particularly perplexing for the dermatologist in their daily practice. However, they differ from each other in terms of their age of onset, predominant location, preferred ethnicity, evolution, associated systemic involvement, distinctive histopathological and molecular characteristics, and their therapeutic response.

A clinical case about a teenage male diagnosed with Dowling-Degos Disease, evaluated at the Pediatric Dermatology Service of Dr. Ricardo Gutiérrez Children's Hospital is reported as an example.

Terra Firma-Forme Dermatosis (TFFD)

Antonio Iannone — 2025-06-12

The authors report the case of a 4-month-old child of Moroccan origins affected by pigmentary dermatitis extending to the body and limbs whose clinical and dermoscopic characteristics allowed a hypothetical diagnosis of Terra Firma Forme Dermatosis. Rubbing with 70 % isopropyl alcohol caused the lesions to disappear, confirming the diagnosis. This condition, whose origin is still not well understood, is decidedly rare in the first months of life.
