Langerhans Cell Histiocytosis Presenting as Anterior Neck Mass in a Child: A Case Report.

Thyroid involvement in Langerhans Cell Histiocytosis (LCH) is rare. We report a 10-year-old Filipino male who presented with a rapidly enlarging goiter. Computed tomography scan showed thyroid and bilateral submandibular masses with malignant features, pulmonary blebs and hepatic cysts.

Monitoring congenital adrenal hyperplasia using blood spot 17-hydroxyprogesterone assay.

Blood spots taken by finger prick collected on filter paper cards can provide an option to venous blood extraction in monitoring 17-OHP levels in children with Congenital Adrenal Hyperplasia (CAH). This study was done to evaluate the usefulness of blood spot 17-OHP in monitoring disease control in pre-pubertal children with CAH, to correlate it with simultaneously extracted venous 17-OHP levels, and to compare blood spot levels of children with CAH with that of normal non-virilized children. Nine pre-pubertal children with CAH (1 male; 8 females) were enrolled in the study.
