Review
Syringocystadenocarcinoma papilliferum (SCACP) is a rare and aggressive malignant adnexal tumor originating from apocrine or pluripotent appendageal glands, often associated with a preceding syringocystadenoma papilliferum (SCAP) or nevus sebaceus (NS). This systematic review rigorously examines SCACP through an analysis of 78 cases documented between 1980 and 2024. The study aims to provide a comprehensive review of the clinical manifestations, diagnosis, treatment modalities, and outcomes associated with SCACP, while also reappraising its associations, particularly with NS. SCACP predominantly affects older adults, with an average age of 66.3 years and a slight male predominance, commonly presenting as ulcerated nodules or plaques on the scalp. This review highlights the aggressive nature of SCACP, evidenced by significant rates of metastasis and recurrence. Treatment is primarily surgical, with Mohs micrographic surgery offering potential benefits in terms of margin control and cosmetic outcomes. The association of SCACP with NS is critically evaluated, suggesting a complex etiopathogenesis and underscoring the importance of recognizing this association for timely diagnosis and management. Our review also briefly discusses potential pitfalls faced by clinicians in the diagnosis of SCACP. Our findings emphasize the need for standardized treatment protocols and further research into targeted therapies to improve patient outcomes in SCACP.

Meta-Analysis
PURPOSE
The aim is to increase the understanding of lacrimal gland pleomorphic adenoma's recurrence rate and the factors that influence it.
METHODS
A systematic search of PubMed, SCOPUS, Cochrane Library, and CINAHL was conducted following PRISMA guidelines. The data in the included studies were extracted and analyzed.
RESULTS
Twenty-two studies were included representing 963 patients from 12 different countries. The pooled analysis of the recurrence rate was 8.83% (95% CI: 5.08-13.50). In the event of recurrence, there was a 75.17% (95% CI: 65.98-82.94) chance of benign recurrence and a 28.35% (95% CI: 19.66-38.41) chance of malignant recurrences, with malignant recurrence occurring almost exclusively after a benign recurrence. The results showed that 47.09% (95% CI: 24.60 to 70.22) of recurrent tumors had a ruptured pseudocapsule and 6.35% (95% CI: 0.82 to 16.54) had an intact pseudocapsule with a significant difference between the two. Of the recurrent tumors, 51.50% (95% CI: 9.28 to 92.39) were biopsied compared to 8.83% (95% CI: 3.40 to 16.49) of the total; the difference between these two proportions was also found to be significant.
CONCLUSION
There was a statistically significant difference in the rates of recurrence between tumors that were either biopsied or had a ruptured pseudocapsule compared to those that did not. This evidence adds additional support for excisional biopsy being the procedure of choice for LGPA and reinforces the importance of keeping the pseudocapsule intact during surgical resection.

Meta-Analysis Review
Laser enucleation of the prostate (LEP) and robotic-assisted simple prostatectomy (RASP) are two main treatment methods for large benign prostatic hyperplasia (BPH), but the superiority between these two methods in treating large BPH is currently unclear. This study aims to conduct a meta-analysis to compare the efficacy and the safety of LEP and RASP in treating large BPH. We systematically searched the PubMed, Embase, and Cochrane Library databases for studies that compared safety and efficacy outcomes of both LEP and RASP. Review Manager 5.3 was used for the meta-analysis. Six studies with a total of 1235 patients were included in the analysis. Resected adenoma weight was similar in LEP than RASP group. Operative time [mean difference (MD) - 67.96; 95% confidence interval [CI] - 131.66 to - 4.25; p = 0.04], catheterization time (MD -6.31; 95% CI - 9.44 to - 3.18; p < 0.0001), and length of stay (MD - 2.44; 95% CI - 3.55 to - 1.34; p < 0.0001) were lower in LEP. The International Prostate Symptom Score, maximum urinary flow rate, prostate-specific antigen, and post-void residual urine volume were also comparable between two groups. Furthermore, LEP demonstrated lesser hemoglobin decrease (MD - 0.50; 95% CI - 0.96 to - 0.05; p = 0.03), lower blood transfusion rate [odd ratio (OR) 0.23, 95% CI 0.08-0.66; p = 0.006], and lower rate of Clavien-Dindo Grade ≥ 3 complications (OR 0.435, 95% CI 0.189-0.998; p = 0.049). Finally, there was no significant difference in overall complications between two groups. Current evidence shows that LEP offers favorable perioperative outcomes compared with RASP. However, there was no conclusive evidence that LEP was advantaged in terms of efficacy outcomes.

Review
In this systematic review, we aimed to evaluate the clinicopathological profile of sclerosing polycystic adenoma (SPA). PubMed, Scopus, EMBASE, Lilacs, Web of Science, and gray literature were searched to access cases of SPA in salivary glands. One hundred and thirty cases of SPA were found across 61 selected articles. SPA affected mainly the parotid gland of adults with a mean age of 44.6 years old, with a slight preference for females. The lesion was usually presented as a painless firm mass with a long period of evolution. Histologically, they are well-delimitated lesions composed of acinar and ductal elements with a variety of cytomorphologic features surrounded by a densely collagenized stroma. PI3K was the most common gene mutation related to SPA. SPA is a benign condition that mainly affects the parotid gland of female patients and it is usually treated by surgical resection with a good prognosis.

Meta-Analysis Review
BACKGROUND
Anatomical endoscopic enucleation of the prostate (AEEP) is recommended for first line surgical treatment of benign prostatic obstruction (BPO) caused by moderate and large prostatic adenoma. However, its role in the retreatment setting after failed previous surgical treatment for BPO remains uncaptured. In this scope, we performed a systematic review and meta-analysis aiming to assess the safety and efficacy of AEEP in the retreatment setting.
METHODS
We searched PubMed, Cochrane Library and Embase databases from inception to March 2022 for prospective or retrospective studies involving patients undergoing prostatic enucleation for recurrent or residual BPO after previous standard or minimally invasive surgical treatments for BPO. Based on data availability, we performed a meta-analysis comparing AEEP in patients with recurrent or residual BPO versus AEEP for primary BPO.
PROSPERO
CRD42022308941).
RESULTS
We included 15 studies in the systematic review and 10 in the meta-analysis (6553 patients, 841 with recurrent or residual BPO and 5712 with primary BPO). All included studies involved patients undergoing HoLEP or ThuLEP. In terms of Qmax, post-void residual, International Prostate Symptom Score, removed adenoma, operative time, duration of catheterization and hospital stay, as well as complications, HoLEP for recurrent or residual BPO was equally effective compared to HoLEP for primary BPO up to 1 year postoperatively. Importantly, the beneficial effect of HoLEP on the retreatment setting was observed after previous standard or minimally invasive surgical treatments for BPO. The overall strength of evidence for all outcomes was deemed very low.
CONCLUSIONS
HoLEP may be safely and effectively used in experienced hands for the surgical treatment of recurrent or residual BPO in patients with large or moderate prostates following previous open, endoscopic or minimally invasive surgical treatment for BPO.

Review
OBJECTIVES
Carcinoma ex Pleomorphic Adenoma (CXPA) is a rare primary salivary gland malignancy, typically arising from a pre-existing pleomorphic adenoma. This systematic review examines prognostic factors affecting overall survival (OS) in major and minor salivary gland CXPA.
MATERIALS AND METHODS
Systematic review of MEDLINE, Cochrane, Scopus, Web of Science, CINAHL, and Open Grey databases from inception to 31st March 2022 for all English-language literature pertaining to 'carcinoma ex pleomorphic adenoma'. All study types with greater than five patients with CXPA of the major and minor salivary glands were eligible for inclusion.
RESULTS
Of 8143 studies, 39 studies (n = 5637 patients) meeting the inclusion criteria were included. Median OS at one, three, five, and ten years were 90.0 %, 72.0 %, 61.9 %, and 45.0 % respectively for all CXPA. Higher staging, T stage, nodal disease, grading, and invasion ≥ 1.5 mm had worse outcomes. Histological subtype, perineural invasion, and radiotherapy did not demonstrate a consistent trend. Three studies were evaluated to have high risk of bias, and was removed for sensitivity analysis.
CONCLUSION
Survival outcomes worsen with time for all salivary gland CXPA. Further research on histopathological features and the utility of radiation therapy is required to guide patient selection for more aggressive treatment.

Meta-Analysis Review
This study is a systematic review and meta-analysis to assess the overexpression rate of HER2 in patients with salivary gland tumors. We included peer-reviewed publications from 1995 to 2020, indexed in medical databases, using search terms such as "human epidermal growth factor receptor 2 (HER2)" and "salivary gland tumors", and extracted relevant data. The extracted data were analyzed with RevMan 5.3 software. Intra-and intergroup post hoc analyses of outcome variables were performed using t-tests, and the rates of HER2 positivity among studies were evaluated. 80 studies were included in the analysis. The positive rates of HER2 ranged from 3.3% to 84.0% and 1% to 9% in malignant and benign subtypes, respectively. The highest HER2 overexpression rate among malignant tumors was in salivary ductal carcinomas (SDC), with a 45% positive rate (CI 95%: 21.9-70.3%). Mucoepidermoid carcinoma (MEC) had the highest positive rate of 84% (CI 95%: 74.1-90.0%). Among benign salivary gland tumors, the highest rate was found in myoepithelioma, with a positive rate of 9% (CI 95%: 1.7-33.6%). The highest rate of HER2 overexpression is present in malignant subtypes of salivary gland tumors, more specifically in salivary ductal carcinoma, mucoepidermoid carcinomas, salivary duct carcinoma in situ, and carcinoma ex pleomorphic adenoma.

Meta-Analysis Review
OBJECTIVES
Salivary duct carcinoma (SDC) is a rare, aggressive malignancy with a poor prognosis. These tumors frequently stain positive for HER2/ErbB2, but data on the prognostic significance of HER2 status in SDC are mixed. We sought to determine whether HER2 status affects survival outcomes in SDC.
METHODS
PubMed, Embase, and Web of Science databases were searched from inception to October 2020. Eligibility was restricted to studies reporting HER2/ErbB2 overexpression in histologically confirmed de novo SDC or SDC ex pleomorphic adenoma, with corresponding overall (OS) and disease-free (DFS) survival measures. Separate multivariable and univariable meta-analyses were performed using random-effects models. Statistical heterogeneity was estimated by Cochran's Q and I tests. Funnel plots were generated and Egger's test was used to assess for publication bias. The risk of bias was assessed with the Newcastle-Ottawa Scale.
RESULTS
Of 183 unique citations, 14 studies of 663 patients were included. Most included studies determined HER2 status according to ASCO/CAP guidelines. The univariable meta-analysis did not reveal an effect between HER2 status and OS (HR 1.09, 95% CI 0.84-1.42). In the multivariable analysis, HER2 positivity was associated with a HR of 1.49 for OS (95% CI 0.96-2.30). Fewer studies reported data for DFS than OS, with no relationship between HER2 status and DFS found on multivariable or univariable meta-analyses.
CONCLUSION
In patients with salivary duct carcinoma, HER2 positivity was not found to be associated with worse overall survival. This information may be useful when counseling patients and considering treatment options. Laryngoscope, 133:476-484, 2023.

Auris, Nasus, Larynx Aug 2022To evaluate surgical approaches and outcomes of pleomorphic adenoma of parotid gland in pediatric population. (Review)
Review
OBJECTIVES
To evaluate surgical approaches and outcomes of pleomorphic adenoma of parotid gland in pediatric population.
METHODS
A systematic search of PubMed and EMBASE was performed to identify articles reporting surgical treatment of pleomorphic adenoma of the parotid gland in children. A qualitative analysis on results was conducted.
RESULTS
Our search included 23 retrospective studies. The number of children with pleomorphic adenoma underwent surgical treatment were 330. Superficial parotidectomy is the most reported type of surgery, total parotidectomy is performed when the tumor occurs in the deep lobe or in revision surgery and limited excisions in selected case of small lesions mainly in the tail of parotid gland. The rate of recurrences after surgery ranged from 0% to 44.4%. Revision surgery was performed in all cases of recurrences. Considering major complications, transient facial paralysis was observed from 0% to 50% of cases after primary and/or revision surgery; Frey's syndrome from 0% to 14.3% of cases regardless of the type of surgeries.
CONCLUSION
Surgical treatment of pleomorphic adenoma of parotid gland in children requires a tailored approach based on the location and extent of the tumor with the main aim of complete excision of the neoplasm. Appropriate surgical approach results in a decrease of recurrence rate and morbidity. Surgical skill is needed to reduce complication rates especially in children.

The Journal of Contemporary Dental... Sep 2021To examine the clinical signs, radiographical features, and demographics of pediatric pleomorphic adenoma (PA) in the minor salivary glands.
AIM AND OBJECTIVE
To examine the clinical signs, radiographical features, and demographics of pediatric pleomorphic adenoma (PA) in the minor salivary glands.
MATERIALS AND METHODS
Several databases were searched for relevant studies. The included studies were assessed for methodological quality. Demographic, clinical, and radiographic data were collected.
RESULTS
Sixteen of 3,121 articles met the inclusion criteria (17 lesions). The mean age was 9.7 ± 3.9 years and majority were females = 10 (59%). It is commonly presented as asymptomatic swelling = 16 (94.1%), in the hard palate 13 (76.5%). Radiographically, most were well-defined = 15 (93.7%) and 8 (47%) caused erosion or displacement of surrounding tissues.
CONCLUSION
The small size and asymptomatic nature of pediatric PA can render these lesions undiagnosed. On rare occurrences, PA can show calcifications, MRI, or CT enhancement. MRI is the best imaging modality to depict soft tissue content but not subtle erosion of adjacent bony structures.
CLINICAL SIGNIFICANCE
The dentist can be the first to detect PA in the mouth of a child. Augmenting clinical examination with radiographic examination is paramount to ensure adequate diagnosis of PA, examine effects on surrounding bone, and maintain close follow-up as watchful waiting is not safe in this population.
