Cryotherapy for localized juvenile spongiotic gingival hyperplasia: preliminary findings on two cases

BACKGROUND Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a distinct subtype of inflammatory gingival hyperplasia that shows lack of response to traditional periodontal treatment, and after surgical excision, recurrence rate of 6-16% has been reported. CASE REPORT Two girls (11- and 9-year-old) with multifocal red patches along the maxillary and mandibular labial gingiva showed no regression of the lesions after basic periodontal treatment. Surgical excision of focal lesion in each case was performed, which showed typical features of LJSGH. In both cases, the lesions presented recurrence. Hence, cryotherapy sessions in all lesions were performed. CONCLUSION Cryotherapy appears to be successfully in LJSGH and well received by paediatric patients.

Squamous cell carcinoma antigen as a prognostic marker and its correlation with clinicopathological features in head and neck squamous cell carcinoma: Systematic review and meta‐analysis

BACKGROUND Several studies investigate the prognostic value of squamous cell carcinoma antigen (SCC-Ag) in head and neck squamous cell carcinoma (HNSCC) patients, with contradicting findings. Considering this, the aim of this study was to evaluate the prognostic value of high SCC-Ag levels and its association with clinicopathological features of HNSCC. MATERIAL AND METHODS PubMed, SCOPUS, and Cochrane Library were searched for relevant studies up to December 2015. English-language publications assessing clinicopathological features of HNSCC and the prognostic significance of SCC-Ag in this disease were included. A meta-analysis was performed using Review Manager 5.3 and STATA version 14 software to clarify a possible association between SCC-Ag and clinical outcomes. RESULTS A total of 11 studies met inclusion criteria, comprising 1901 cases of HNSCC. The results of the meta-analysis showed that there was significant correlation between high SCC-Ag levels and males (odds ratio [OR]=2.99, 95% CI: 1.18-7.57, P=.02 fixed-effect), and advanced TNM stages (OR=3.18, 95% CI: 1.88-5.38, P<.0001 random-effect). The survival meta-analysis showed a pooled hazard ratio for disease-free survival (DFS) and overall survival (OS) of 1.01 (95% CI: 0.70-1.31) and 0.86 (95% CI: 0.54-1.17), respectively. CONCLUSION Our meta-analysis suggests that elevated SCC-Ag levels have a significant correlation with males and TNM stage, but may not be used as predictive marker for OS and DFS in HNSCC patients.

Synchronous Polymorphous Adenocarcinoma and Canalicular Adenoma on the Upper Lip: An Unusual Presentation and Immunohistochemical Analysis

Multiple salivary gland tumors (MSGTs) are most common in the major than minor salivary glands. The most MSGTs are synchronous, either benign or malignant. A 61-year-old woman was referred presenting nine submucosal nodules, firm to fluctuant, being five nodules on the right side and four nodules on the left side of the upper lip. An incisional biopsy was performed. Hematoxylin and eosin staining was performed in 5-µm sections for histopathologic analysis. Immunohistochemical reactions were carried out in 3-µm sections in accordance with manufacturer’s instructions. The histopathological analysis showed focal area containing low-grade polymorphous adenocarcinoma (PAC) and multiple canalicular adenomas (CAs). Immunohistochemical analysis for each lesion was carefully investigated. Here, we present an unusual case of synchronous PAC and multiple CAs of the minor salivary glands, affecting the upper lip, which appears to be the first case showing PAC and CA.
