Histiocytosis with intracytoplasmic worm-like bodies
A self-limiting non-Langerhan's histiocytosis of early childhood.
Last updated
Benign cephalic histiocytosis is a non-Langerhan's histiocytosis that is uncommon and self-limiting. It usually begins towards the end of the first year of life, initially affecting the head and neck with small yellow to reddish-brown papules that heal on their own. Histological findings include dermal proliferation of histiocytes with intracytoplasmic comma-shaped bodies, covered vesicles, and desmosome-like structures.
