Radioiodinated metaiodobenzylguanidine [(131)I-MIBG] is commonly used to treat resistant neuroblastoma or metastatic pheochromocytoma [MP] with little non-hematopoietic toxicity. We describe here transient sialoadenitis, a previously unreported complication. Ten patients [9 neuroblastoma and 1 MP] received 12-18 mCi/kg of (131)I-MIBG. Five patients had bilateral parotid swelling, two with associated buccal discomfort within 24 hr of injection which subsided within 48 hr. Grade 3 or 4 serum amylase elevation was documented in 8/8 patients tested [median 1,336; range: 576-8,830 U/L] which normalized [25-125 U/L] within 4-14 [median 5.5] days. Serum lipase remained normal. Patients did not develop subsequent dry mouth or dysphagia.

The primary indication of fine-needle aspiration cytology of the head and neck region is a thyroid nodule or a mass located in the cervical area or the head. Although a thyroid nodule may raise the suspicion of malignancy, less than one in 20 cases results in a carcinoma. In addition, the list of differential diagnoses is quite different according to the age of the patient. A number of benign lesions, such as branchial cysts, sialadenosis, and sialoadenitis are often seen in childhood and youth. The malignant lesions that are on the top of the list of a pediatric mass of the head and neck (H&N) region include rhabdomyosarcoma, neuroblastoma, and papillary carcinoma of the thyroid gland. This critical review of the diagnostic features of a pediatric mass of the H&N region is accompanied by panels of several cytology features that may be of help to the cytopathologist and clinician.
