Background

Human papillomavirus (HPV)-related tonsillar squamous cell carcinoma (TSCC) has recently been characterized as a distinct subset with a favorable prognosis. The prevalence and clinicopathologic significance of HPV-related TSCC in Koreans are not well known.

Methods

HPV in situ hybridization (ISH) accompanied by p53, p16, pRb, and cyclin D1 immunohistochemical staining were performed on 89 resection cases of TSCC from 2000 through 2010.

Results

HPV was detected by ISH in 59 of 89 cases (66.3%). HPV-positive TSCCs were more common in younger ages (p=0.005), and tumor sizes were smaller in the HPV-positive compared to the HPV-negative group (p=0.040). Positive HPV staining was significantly correlated with p16 expression (p<0.001), pRb inactivation (p=0.003), and cyclin D1 down-regulation (p<0.001) but not with p53 expression (p=0.334). Seventeen cases that showed p16-immunopositivity with HPV-negativity by ISH were retested by HPV typing; HPV DNA was not detected in all cases. There was no significant difference between HPV-positive and HPV-negative patients either in the disease-specific survival (DSS, p=0.857) or overall survival (p=0.910). Furthermore, pRb-inactivated cases showed better DSS (p=0.023), and p53-positive cases showed worse DSS (p=0.001).

Conclusions

Although high HPV prevalence was noted, it was not correlated with histopathologic findings or survival benefit. In addition to p53 expression, pRb inactivation along with p16 overexpression and down-regulation of cyclin D1 are thought to be important pathogenetic steps for developing TSCCs.

Abstract PDF

Background

Q fever caused by Coxiella burnetii presents with diverse clinical and pathological features including subclinical or cholestatic hepatitis. However, the pathological features of liver biopsies from patients with Q fever have not been well described.

Methods

Clinical features and pathological findings of liver biopsies were reviewed in seven cases of Q fever that were confirmed by serological, microbiological, or molecular tests.

Results

All cases presented with fever. Liver enzymes were mildly elevated except one case with marked hyperbilirubinemia. Characteristic fibrin ring granulomas were present in three cases, epithelioid granulomas with eosinophilic infiltration in two cases, extensive extravasated fibrins without ring configuration mimicking necrotizing granuloma in one case, and acute cholangitis without granuloma in one case. All cases were treated with antibiotics for 20 days. Six cases were completely cured, but one suffered from multiorgan failure.

Conclusions

C. burnetii infection is uncommon, but should always be considered in patients with acute hepatitis and fever. Because variable-sized circumferential or radiating fibrin deposition was a consistent feature of the present cases, Q fever can be strongly suggested by pathological features and confirmed by serological and/or molecular tests.
