Insights

This report details the first benign intracystic phyllodes tumor in the inguinal region. The rare tumor, initially suspected as lymphoma, was successfully resected and characterized.

Area of Science:

  • Oncology
  • Pathology
  • Surgical Case Report

Background:

  • Inguinal masses can present diagnostic challenges, with differential diagnoses including malignant lymphoma.
  • Phyllodes tumors are rare, typically occurring in the breast, and their presentation in the inguinal region is exceptionally uncommon.

Purpose of the Study:

  • To report the first case of a benign intracystic phyllodes tumor in the inguinal region.
  • To describe the clinical presentation, surgical findings, and histopathological characteristics of this rare entity.

Main Methods:

  • Case presentation of a 51-year-old female with an inguinal mass.
  • Surgical resection of the tumor.
  • Histopathological examination of the resected specimen.

Main Results:

  • The resected tumor was a well-circumscribed, benign intracystic phyllodes tumor measuring 3.5x2.5 cm.
  • Microscopic findings revealed hyperplastic epithelium-lined cysts with leaf-like stromal projections.
  • Tumor cells showed strong positivity for estrogen and progesterone receptors.

Conclusions:

  • Benign intracystic phyllodes tumor is a rare differential diagnosis for inguinal masses.
  • Histopathological analysis is crucial for accurate diagnosis, distinguishing it from malignant conditions.
  • Hormone receptor positivity may have implications for understanding tumor behavior.

Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Diverticular Disease of the Colon01:27

Diverticular 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...

Appendicitis01:19

Appendicitis

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...

Gallbladder

The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
