Summary
A rare congenital presacral epidermoid cyst causing hydronephrosis was identified in a Taiwanese patient. Surgical removal was successful, highlighting the importance of thorough evaluation for presacral tumors.
Area of Science:
- Urology
- Surgical Oncology
- Pathology
Background:
- Presacral epidermoid cysts are rare congenital lesions of ectodermal origin.
- Presacral epidermoid cysts associated with hydronephrosis are exceptionally rare.
- This is the first reported case in Taiwan.
Observation:
- A 62-year-old woman presented with low abdominal pain.
- Computed tomography revealed a large (20 x 15 x 12 cm) multilobulated cystic presacral tumor.
- Severe right hydronephrosis was noted secondary to the tumor.
Findings:
- Laparotomy successfully removed the presacral tumor.
- Pathological diagnosis confirmed an epidermoid cyst.
- The large cystic tumor mimicked an ovarian tumor on imaging.
Implications:
- Thorough preoperative evaluation is crucial for all presacral tumors, symptomatic or not.
- Complete surgical excision is the recommended treatment.
- Preservation of adjacent organ function should be a priority during surgery.

01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
01:24Nephrotic Syndrome I : Introduction
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...
01:21External Anatomy of the Kidney
The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

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...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:26Nephrotic Syndrome II : Assessment and Medical Management
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document any history...
