Amyloid goiter with parathyroid involvement: a case report and review of the literature.

Although involvement of the thyroid gland by amyloid is a relatively common phenomenon, diffuse enlargement of the gland secondary to infiltration by amyloid is infrequent. We report the pathologic findings in a case of primary amyloid goiter with involvement of a parathyroid gland in an euthyroid patient who presented to his physician with an enlarged thyroid, upper airway obstructive symptoms, and dysphagia. The clinical features of amyloid goiter, including difficulties in preoperative diagnosis and management, are discussed.

Rapid detection of HSV from cytologic specimens collected into ThinPrep fixative.

OBJECTIVE: Herpes simplex virus (HSV) infection is associated with substantial morbidity and mortality in neonates. A diagnosis of HSV on cervical cytologic studies could lead to a cesarean section, with an increase in the risk of maternal morbidity. The identification of viral lesions in sexually active women has medical and social implications. There have been reports of false positive diagnoses of HSV in patients with altered endocervical cells and with cervical intraepithelial neoplasia 3. We evaluated a polymerase chain reaction (PCR)-based assay to detect HSV-1 and HSV-2 in routinely collected cervical cytology specimens in ThinPrep fixative (Cytyc Corp., Marlborough, Massachussets, U.S.A.). STUDY DESIGN: DNA was extracted from five cases that demonstrated cytologic changes suggestive of an HSV infection. PCR amplification with subsequent gel electrophoresis was performed to detect the presence of HSV. RESULTS: HSV DNA was detected in three of five cases that were cytologically diagnosed as suspicious or strongly suspicious for HSV infection. CONCLUSION: The combination of the ThinPrep liquid-based method for cervical cytology with PCR allows prompt confirmation of the diagnosis of HSV without sacrificing the diagnostic morphology on the slide.
