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...
Disorders of the Female Reproductive System01:24

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
Uterine Tubes01:16

Uterine Tubes

The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Assessment of the Rectum and Anus01:25

Assessment 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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Summary
This summary is machine-generated.

Parasitic myomas can form spontaneously or iatrogenically, particularly after morcellation during laparoscopic surgery. Surgeons must be aware of this risk and take precautions to prevent parasitic myoma formation.

Area of Science:

  • Gynecology
  • Surgical Pathology

Background:

  • Parasitic myomas are uterine fibroids that detach from the uterus and implant elsewhere.
  • Their occurrence can be spontaneous or iatrogenic, posing diagnostic and surgical challenges.

Purpose of the Study:

  • To present a large case series of parasitic myomas.
  • To investigate the causes, associations, and risk factors contributing to their formation.

Main Methods:

  • A retrospective chart review of 12 patients diagnosed with parasitic myomas between 2000 and 2008.
  • Systematic data collection included prior surgical history, morcellation use, and myoma location.
  • Pathologic confirmation of all parasitic myoma specimens was performed.

Main Results:

  • Parasitic myomas were confirmed in 12 patients, often associated with prior abdominal surgery (10/12).
  • Morcellation procedures, especially laparoscopic, were linked to parasitic myoma development (8/12 patients).
  • Myomas were predominantly found in the pelvis (14/15), including retroperitoneal locations and the bladder, with some on the gastrointestinal tract.

Conclusions:

  • Parasitic myomas can arise spontaneously from pedunculated subserosal fibroids.
  • Iatrogenic formation is common after surgery, particularly with morcellation techniques.
  • Increased awareness and intraoperative precautions are crucial given the rising rates of laparoscopic procedures.
