This article investigates the effect of patient age on postoperative pathway length of stay (LOS) for head and neck surgery. Aggregate clinical results for 43 patients, enrolled in the CCP from June 1996-July 1997, are described. Patient age, comorbid status, and postoperative complications are analyzed with respect to impact on LOS. ⋯ The CCP-reported performance improvement achieved by this pathway suggests improved resource use, and improved patient outcomes are achieved for postoperative care of head and neck surgery patients. Our experience suggests that advancing age creates a clinically significant increase in resource use represented by our finding of increasing LOS. This finding warrants further investigation.

Management of squamous cell carcinoma of undetermined primary tumors in the head and neck region is controversial. Here we report the Southern California Kaiser Permanente experience with these patients. ⋯ Radiotherapy is very effective in reducing the rate of appearance of a potential primary site. However, in the absence of advanced neck disease (N1 and N2A without extracapsular extension), radiotherapy can be reserved for salvage. Radiotherapy alone results in poor outcomes in patients with advanced/unresectable neck disease, and incorporation of concurrent chemotherapy and cytoprotective agents should be investigated.

Anaerobic abscess formation within a thyroid cyst is rare but still possible, although aerobic thyroid abscess formation in the thyroid gland after fine-needle aspiration (FNA) has been observed in immunocompromised patients. ⋯ This article reported, for the first time, on the formation of an anaerobic thyroid abscess after FNA in a healthy subject. We recommended careful aseptic procedure and adequate isolation processes, such as wearing a mask to avoid an unfavorable outcome as a result of a bacterial infection.

To study the efficacy of stereotactic radiosurgery in salvaging early-stage persistent and recurrent nasopharyngeal carcinoma (NPC) after primary radiotherapy. ⋯ Our preliminary results indicate that stereotactic radiosurgery is an effective treatment modality for persistent and recurrent T1-T2 NPC, and early control rate seems to be comparable to other salvage treatments. More clinical experiences and longer follow-up are still needed to validate our results and to address fully the role of radiosurgery in salvaging local failures of NPC.

Case Reports
Calcifying epithelial odontogenic (Pindborg) tumor with malignant transformation and metastatic spread.
Pindborg tumors (calcifying epithelial odontogenic tumors) are uncommon neoplasms of odontogenic origin most often located in the posterior mandible. First described in detail in 1955 by Pindborg, these tumors are considered benign but can be locally aggressive in nature, with recurrence rates of 10% to 15% reported. The malignant form of this tumor is exceedingly rare. ⋯ This article describes only the second case of odontogenic carcinoma. The transformation from benign to malignant histologic findings has not previously been documented in this tumor. The salient clinical features of this case are presented along with supportive pathologic and radiologic evidence.
