ABSTRACT
Langerhans cell histiocytosis may be seen with goiter and histiocytic infiltration of the thyroid. We report a 2 1/2-year-old boy who had goiter and primary hypothyroidism develop, later had pulmonary disease, and died of neurologic involvement. Autopsy lesions suggested a transitional dendritic cell precursor of the epidermal Langerhans cell. Of the reported cases of Langerhans cell histiocytosis with goiter in children and adolescents, 82% were male when the relative incidence of Langerhans cell histiocytosis is two males to one female.

In a series of 37 consecutive CT scans performed in children referred to our pediatric endocrine unit, an empty (eight) or partially empty (one) sella turcica was found in nine (24%) patients with short stature or delay in sexual maturation, precocious puberty, or hypoparathyroidism. The size and contour of the sella were abnormal in only three patients. Five of the nine children had evidence of decreased growth hormone secretion as determined by subnormal GH secretory responses to provocative tests (peak GH concentration less than 7 ng/ml) or assessment of endogenous 24-hour GH secretion (mean 24-hour GH concentration less than 3 ng/ml). Two children had multiple pituitary hormone deficiencies. Although primary empty sella syndrome was often associated with hypothalamic-pituitary dysfunction in this series, the prevalence of an empty sella in normal children is unknown. Further identification and evaluation of children with empty sella may provide new information regarding the cause of pituitary dysfunction in childhood.
