Self-healing infantile familial cutaneous mucinosis.

Childhood cutaneous mucinoses have been rarely reported and are difficult to classify. We describe two brothers who developed multiple, extensive cutaneous lesions during the first few months of life. Histologically the lesions were composed of mucin deposits in the dermis. In the first patient, the lesions spontaneously disappeared over the years. We believe that familial self-healing cutaneous mucinosis represents a unique entity not previously reported.
