congenital self-healing reticulohistiocytosis
Pronunciation: ret-ik-you-low-his-tee-oh-sy-TOH-sis
A benign form of Langerhans cell histiocytosis presenting at birth with papules and nodules that spontaneously resolve.
Full Definition
Congenital self-healing reticulohistiocytosis, also known as Hashimoto-Pritzker disease, is a unique form of Langerhans cell histiocytosis that presents at birth or within the first few weeks of life. The condition manifests as multiple red-brown papules and nodules that may resemble 'blueberry muffin' lesions, causing initial concern for serious systemic disease. Despite the dramatic appearance, these lesions characteristically undergo spontaneous resolution without treatment, typically within months to years. Proper documentation includes lesion morphology, distribution, and the benign natural history to differentiate from other forms of LCH requiring systemic therapy.
Usage
Usage note: Reassure families about the benign nature and self-resolution. Avoid unnecessary systemic workup.
