Clinical Case Reports
|January 23, 2026
Summary
Umbilical endometriosis, a rare condition, presents as cyclic umbilical pain and bleeding. Surgical excision is the recommended treatment, offering a low risk of recurrence.
Area of Science:
- Gynecology
- Surgical Pathology
Background:
- Endometriosis affects 6-10% of women of reproductive age.
- It typically involves pelvic organs but can occur in extrapelvic locations.
- Umbilical endometriosis (Villar's node) is a rare manifestation, seen in 0.5-1% of cases.
Purpose of the Study:
- To report a case of umbilical endometriosis.
- To highlight diagnostic and management strategies for this rare condition.
Main Methods:
- A case of a nulliparous woman with cyclic umbilical pain and swelling post-laparoscopy was analyzed.
- Diagnosis was confirmed via histopathology with CD10 immunostaining.
- Surgical excision with primary closure was performed.
Main Results:
- Histopathology confirmed umbilical endometriosis.
- The patient underwent successful surgical excision.
- The condition presented with cyclic bleeding and swelling.
Conclusions:
- Umbilical endometriosis should be considered in women with umbilical masses and cyclical symptoms.
- Clinical diagnosis relies on cyclical umbilical pain and bleeding.
- Complete surgical excision is the treatment of choice with favorable outcomes.

01:22Bleeding in Fresh Concrete
557
Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

02:33Stereoisomerism of Cyclic Compounds
11.0K
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular symmetry and stereoisomerism of cyclic compounds. 1,2-Dimethylcyclohexane is used as a case study to evaluate the possible number of stereoisomers. Here, given the multiple (n = 2) chiral centers, there are 2n = 4 possible configurations that lack a plane of symmetry, as the ring skeleton exists in a non-planar chair conformation. In addition,...

01:19Cyclic Processes And Isolated Systems
3.4K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

01:10Voltammetric Techniques: Cyclic Voltammetry
1.5K
Cyclic voltammetry (CV) is an electrochemical technique used to investigate the redox properties of a chemical species. It involves measuring the current response of an electrochemical cell as a function of the applied potential. The setup for cyclic voltammetry typically consists of a working electrode, a reference electrode, and a counter electrode—all immersed in an electrolyte solution. The working electrode is where the redox reaction of interest occurs, while the reference electrode...
