Summary
This case study details a rare instance of endometriosis affecting both the appendix and sigmoid colon. Diagnosis of gastrointestinal endometriosis can be challenging, especially with multiple organ involvement.
Area of Science:
- Gastroenterology
- Gynecology
- Surgical Pathology
Background:
- Gastrointestinal endometriosis is a rare condition that can mimic other abdominal pathologies.
- Endometriosis typically affects the ovaries, fallopian tubes, and pelvic peritoneum.
Observation:
- A 41-year-old woman presented with acute right lower quadrant pain, elevated inflammatory markers, and CT findings suggestive of appendiceal mucocele.
- Initial treatment with antibiotics was followed by surgical resection of the appendix and sigmoid colon.
Findings:
- Histological examination confirmed an endometriotic nodule within the appendix, causing a mucocele.
- The appendiceal endometriosis had invaded the wall of the sigmoid colon, indicating a simultaneous double gastrointestinal location.
Implications:
- This case highlights the diagnostic challenges of gastrointestinal endometriosis due to varied presentations.
- Clinicians should consider the possibility of concomitant endometriosis in multiple gastrointestinal sites in women of reproductive age presenting with relevant symptoms.

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

01:23Anatomy of the Intestines
87.4K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

02:31Homologous Recombination
63.0K
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

92.9K
Cells pull particles inward and engulf them in spherical vesicles in an energy-requiring process called endocytosis. Phagocytosis (“cellular eating”) is one of three major types of endocytosis. Cells use phagocytosis to take in large objects—such as other cells (or their debris), bacteria, and even viruses.
