Radiology Case Reports
|January 30, 2020
Summary
This case report details a rare squamous cell carcinoma of the rectovaginal septum in a 35-year-old female. Combined chemoradiotherapy led to complete resolution, highlighting a potential treatment approach for this rare cancer.
Area of Science:
- Gynecologic Oncology
- Rare Cancers
- Medical Imaging
Background:
- Primary rectovaginal septum cancers are exceptionally rare, with adenocarcinoma being most common.
- Squamous cell carcinoma of this region is exceedingly rare, with only one prior reported case.
- These tumors often present late with nonspecific pelvic symptoms.
Observation:
- A 35-year-old female presented with a rectovaginal mass.
- Pelvic ultrasound detected the mass, with further characterization by CT and PET-CT.
- Diagnosis was confirmed via transvaginal biopsy.
Findings:
- The patient was diagnosed with squamous cell carcinoma of the rectovaginal septum.
- Combined chemoradiotherapy was administered as treatment.
- Follow-up magnetic resonance imaging (MRI) showed complete resolution of the mass.
Implications:
- This case represents the second report of primary squamous cell carcinoma of the rectovaginal septum.
- Combined chemoradiotherapy appears effective in managing this rare entity.
- Further research is needed due to the lack of established management guidelines for rectovaginal septum cancers.

6.0K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

01:29Classification of Epithelial Tissues: Stratified Epithelium
12.3K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

3.7K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

02:21Cancers Originate from Somatic Mutations in a Single Cell
14.4K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:21Barrett Esophagus-I: Introduction
512
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...
