Squamous cell carcinomas in several anatomical sites are caused by human papillomaviruses (HPV), and oncogenic double-stranded DNA viruses. There are about 200 genotypes; HPV16 is the most often occurring variant. Potential ways of infection are skin warts, sexual activity, exposure, immunization, or oral sex.

Primary lymphoma of the female genital tract (PLFGT) is a rare entity with nonspecific symptoms. Its prognosis relies on accurate and quick diagnosis and therapy despite the lack of standardized management guidelines. This study aimed to explore the clinicopathologic and radiologic characteristics; and differential diagnoses of women with lymphoma of the female genital tract (FGT) treated at the same institution.

Introduction: Despite being less common in recent years, recurrent pleomorphic adenoma still poses a surgical challenge, especially after improper surgery.

Methods: We retrospectively recruited all patients with recurrent pleomorphic adenoma and Carcinoma ex pleomorphic adenoma from February 2007 to April 2024 who were operated upon in a tertiary cancer center. Epidemiological, radiological, and pathological data, risk factors, details of surgical treatment, and surgical/oncological outcomes were analyzed.

Introduction And Importance: Orthotopic neobladder reconstruction may be associated with complications such as neobladder-vaginal fistula (NVF) and uretero-ileal anastomotic stricture which are often managed using stents, though these can be prone to migration.

Case Presentation: We present a 69-year-old lady with a surgical history of radical cystectomy and ileal neobladder that was complicated by a left ureteric stricture and poucho-vaginal fistula for which she underwent a left ureteric stent and bilateral percutaneous nephrostomy (PCN) insertions after which she lost to follow-up. The patient later presented to our center with a right subcostal anterior abdominal wall desmoid tumor for which she underwent wide local excision.

Diaphragmatic fibromatosis is an exceptionally rare condition, with only 2 previously reported cases in the literature. We present the case of a 23-year-old woman with a left hypochondrial swelling measuring 19×18×13 cm on computed tomography. An endoscopic ultrasound-guided biopsy indicated low-grade papillary proliferation.

Background: Although endometrial cancer (EC) is staged surgically, magnetic resonance imaging (MRI) plays a critical role in assessing and selecting the most appropriate treatment planning. We aimed to assess the diagnostic performance of quantitative analysis of diffusion-weighted imaging (DWI) in preoperative assessment of EC.

Methods: Prospective analysis was done for sixty-eight patients with pathology-proven endometrial cancer who underwent MRI and DWI.

Article Synopsis
  • Phyllodes tumors are rare breast growths that can vary in size, with "giant" ones over 10 cm, often appearing as rapidly growing lumps that alter breast shape.
  • Treating these tumors is complex; while surgical removal with clear margins is standard, more extreme cases may necessitate wider excisions or total mastectomy to reduce recurrence risk.
  • A study from March 2022 to September 2023 reviewed three giant phyllodes cases, where patients received nipple-sparing mastectomy followed by immediate reconstruction, aiming to enhance both survival outcomes and aesthetics.

Introduction And Importance: Non-mammary metastases to the breast and axilla are rare instances, and isolated axillary lymph node metastases are especially rare. We present a rare case of left axillary lymph node metastasis from a primary endometrial carcinosarcoma.

Case Presentation: We report a case of a 73-year-old woman who presented with a left breast tail palpable mass.

Introduction And Importance: Highly differentiated follicular carcinoma of the ovary (HDFCO) is a rare type of thyroid carcinoma originating from struma ovarii, consisting of benign-appearing thyroid follicles spread outside the ovarian tissue.

Case Presentation: We present a 22-year-old girl who underwent left salpingo-oophorectomy, omental, and peritoneal biopsies for a complex left ovarian mass. Microscopic examination and Immunohistochemical staining led to the diagnosis of HDFCO with tumor deposits affecting the omental and peritoneal biopsies.

This study aimed to investigate the frequency of MYC/BCL2 co-expression using immunohistochemistry (IHC) in Egyptian patients with diffuse large B-cell lymphoma (DLBCL) and its impact on treatment outcomes, overall survival (OS), and disease-free survival (DFS). A total of 100 adult patients with newly diagnosed DLBCL were included in the study and treated with the R-CHOP regimen. The cases were classified into germinal center B-cell (GCB) and non-germinal center B-cell (non-GCB) subtypes based on IHC.

Article Synopsis
  • The study explores repurposing the lipophilic statins, Simvastatin and Pitavastatin, alongside traditional chemotherapy drugs doxorubicin and cyclophosphamide for treating breast cancer.
  • Research was conducted using breast cancer cell lines MDA-MB-231 and MCF7, focusing on cell viability, cell cycle effects, and apoptosis-related gene expression.
  • Results showed that combining statins with the chemotherapy drugs significantly reduced cell viability and increased apoptosis-related gene expression, particularly in the MDA-MB-231 cell line, suggesting a potential new strategy for breast cancer treatment.

Objectives: This study was conducted to study the expression of both microRNA-29a and microRNA-122, and serum levels of sestrin-2, interleukin-6 (IL-6), and other inflammatory markers among obese children with/and without diabetes mellitus.

Methods: One hundred obese children with diabetes in addition to 100 age- and sex-matched obese children without diabetes, and 100 age- and sex-matched apparently healthy children were included in the study. Expressions of both microRNA-29a and microRNA-122, and serum levels of sestrin-2, IL-6, tumor necrosis factor-α (TNF-α), and high sensitive-CRP (hsCRP) were measured for all included study populations.

Breast cancer stands out as the most frequently identified malignancy, ranking as the fifth leading cause of global cancer-related deaths. The American College of Radiology (ACR) introduced the Breast Imaging Reporting and Data System (BI-RADS) as a standard terminology facilitating communication between radiologists and clinicians; however, an update is now imperative to encompass the latest imaging modalities developed subsequent to the 5th edition of BI-RADS. Within this review article, we provide a concise history of BI-RADS, delve into advanced mammography techniques, ultrasonography (US), magnetic resonance imaging (MRI), PET/CT images, and microwave breast imaging, and subsequently furnish comprehensive, updated insights into Molecular Breast Imaging (MBI), diagnostic imaging biomarkers, and the assessment of treatment responses.

Standard operative management for breast carcinoma has significantly shifted from extensive procedures to minor interventions.Although axillary dissection was a fundamental component of operative management, sentinel biopsy is an actual process for axillary staging. Axillary dissection may be postponed for cases that have negative SLNs or 1 or 2 infiltrated lymph nodes undergoing breast or axillary radiation.

Background: Multifocal (MFBC)/multicentric (MCBC) breast cancer is being more recognized due to the improved imaging modalities and the greater orientation with this form of breast cancer, however, optimal surgical treatment, still poses a challenge. The standard surgical treatment is mastectomy, however, breast-conserving surgeries (BCS) may be appropriate in certain situations.

Methods: A total of 464 cases of MF/MCBC out of 4798 cases of breast cancer were retrospectively analyzed from the database of the Oncology Center, Mansoura University (OCMU), between January 2008 and December 2019.

Background: Despite the strict diagnostic criteria recently proposed for non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP), its incidence is still unknown. Employing a retrospective analysis of the follicular variant of papillary thyroid carcinoma (FVPTC), we investigated the diagnosis, prevalence and postoperative course of NIFTP.

Methods: We examined retrospectively the records of 112 patients who had undergone thyroid surgery and had a postoperative diagnosis of FVPTC at our hospital from 2010 to 2021.
