[An endoscopic transnasal transsphenoidal biopsy for pituitary gland Langerhans cell histiocytosis in a child: a case report].

Endoscopic transnasal transsphenoidal surgery is gaining wide acceptance as the first-line treatment of pituitary tumors in adults, as this procedure is minimally invasive and associated with good outcomes. On the other hand, conventional transcranial and sublabial approaches are chosen for infants as their small anatomical structures pose some difficulty. This study reports on the case of a 5-year-old boy who had a Langerhans cell histiocytosis appearing in the sella.
