Summary
Dermoid cysts, benign tumors lined by skin, can present unusually. This case highlights a dermoid cyst causing irregular vaginal bleeding in a young woman, requiring surgical intervention.
Area of Science:
- Gynecologic Oncology
- Gastrointestinal Surgery
- Pathology
Background:
- Dermoid cysts are benign cystic teratomas originating from germ cells.
- They are typically found in the ovaries but can occur in various locations.
- This report details an unusual presentation of a dermoid cyst in the abdominal cavity.
Observation:
- A 26-year-old female presented with irregular vaginal bleeding.
- Abdominal MRI revealed a space-occupying lesion in the right lower abdomen with specific T2 hyperintensity.
- Surgical exploration identified a subserous tumor of the colon.
Findings:
- The resected tumor was a 5.4 x 4.8 x 3.5 cm soft, elastic mass.
- Cross-section revealed a unilocular cyst containing atheromatous material.
- Pathological examination confirmed the diagnosis of a dermoid cyst.
Implications:
- This case underscores the importance of considering dermoid cysts in the differential diagnosis of abdominal masses, even with atypical presentations.
- While surgical resection was performed, simple excision might have been sufficient for this benign entity.
- Accurate preoperative diagnosis can guide appropriate surgical management and minimize unnecessary procedures.

01:09Large Intestine
The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

01:26Histology of the Large Intestine
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:25Endoscopic Procedures II: Colonoscopy
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
