leiomyoma with hydropic degeneration pathology outlines

Leiomyomas with hydropic change do not have thick smooth muscle cells fascicles but a delicate filigree pattern with oedema fluid as extracellular material [1]. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. Hydropic change is another form of degeneration with a similar MRI appearance, and is due to an accumulation of oedema fluid in the connective tissue of the leiomyoma. In the acute test, group 1 showed a sharply demarcated area of coagulative necrosis that did not express estrogen receptor (ER) or progesterone receptor (PR); group 2 showed a severe hydropic degeneration or necrosis; and group 3 showed regular leiomyoma cells. Cotyledonoid hydropic intravenous leiomyomatosis: a new variant leiomyoma. 2b). They are most common tumors in females. Address correspondence and reprint requests to Dr. Lawrence M.

Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. The cytoplasm s abundant and eosinophilic with elongated bipolar processes. The individual smooth muscle cells are uniform in size and shape and have characteristic oval to elongated with blunt ends ( CIGAR shaped). Diffuse, perinodular, and other patterns of hydropic degeneration within and adjacent to uterine leiomyomas: problems in differential diagnosis. 21 year old woman with bilateral massive ovarian leiomyomata (Mod Pathol 1992;5:586) 31 year old woman with primary ovarian leiomyoma associated with endometriotic cyst presenting with symptoms of acute appendicitis (Diagn Pathol 2009;4:25) 79 year old woman with leiomyoma of the ovary presenting with Meigs' syndrome (J Obstet Gynaecol Res … Hydropic degenerating leiomyomas are characterized by focal accumulation of edema and collagen deposition.

Hydropic degeneration of uterine leiomyoma mimicking a huge ovarian cyst Ifeyinwa Mary Asuzu, Emmanuel Ugwa, Kevin Nwabueze Ezike ABSTRACT Introduction: Leiomyomas are very common neoplasms of the female genital tract. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. Uterine Leiomyoma: These are the benign tumors of smooth muscle of uterus. 3. Uterine leiomyomas are commonly referred to as Fibroids. Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. Cystic degeneration is an extreme sequel of edema. Diffuse hydropic degeneration is considered much less common and may result in exceptionally large tumors, depending on the degree of fluid accumulation . A presumed direct relation between the abundance of intratumoral fluid and presence of ascites seemed justified. Saeed et al. We welcome suggestions or questions about using the website. Increased levels of CA 125 often are associated with some types of malignancy. Microscopically, the nodules were separated by extensive hydropic degeneration. Intramural: within the myometrium. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Morphology: Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. These are the ones which can manifest with menorrhagia. With minimal discussion in the surgical pathology literature, appropriate evaluation may be challenging because the differential diagnosis includes other uncommon uterine disorders such as intravenous leiomyomatosis, diffuse leiomyomatosis, myxoid … Ovary tumor - Leiomyoma. The patient was admitted in the emergency department because of diffuse abdominal bloating and discomfort. Can cause pressure symptoms due to compression on adjoining structures. This will result in hyper responsivenesness to normal levels of estrogen in adults. Edematous change, referred to as hydropic degeneration, is a common form of degeneration seen focally in up to 50% of patients with leiomyoma .

Obesity, lack of exercise are also risk factors for development of leiomyomas. Gross: Marked degrees of hydropic degeneration may have resulted in cystic degeneration, leading to large myometrial cysts. Highly cellular variant and lipoleiomyomas will be yellowish in color. Uncomplicated leiomyomas are of a heterogeneous echo texture and vary from hypoechoic to hyperechoic, sometimes containing calcifications with acoustic shadowing. Hyalinization is the commonest type of degeneration. Pedunculated: Submucosal and subserosal tumors can be pedunculated with the presence of narrow pedicle. Most important risk factor is exposure to environmental estrogens before puberty. 4. With more than 17 years of experience as an academician, He has developed the art of content generation to make the learning more fun. The common cause is due to obstruction of venous drainage at the periphery of the lesion. Red Degeneration: This is due to hemorrhagic infaction of a leiomyoma. 1.

Author information: (1)Department of Pathology, NKP Salve Institute of Medical Sciences and Research Centre, Nagpur. We describe a case of a 35-year-old woman with a pedunculated uterine leiomyoma with diffuse hydropic degeneration presenting as a giant abdominal mass. 2. Leiomyoma dissects into myometrium (black arrow) at the cornu; hydropic change is present around smooth muscle bundles (perinodular hydropic degeneration) Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. But can manifest with abnormal uterine bleeding which is more common in submucosal leiomyomas. If the tumor is very large, the degenerative changes can be seen. This website is intended for pathologists and laboratory personnel but not for patients. The mass grossly contained serous and hemorrhagic fluids in the cavities, and pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. Etiology: Exact etiology is not known, however age of menarche and parity are important risk factors. No reported case of pseudo-Meigs syndrome presenting with hydropic degeneration of uterine leiomyoma and an elevated CA 125 level could be found on a MEDLINE search. Most often asymptomatic. Pathology confirmed that the mass was a leiomyoma with hydropic and myxoid degeneration. Geographic areas of hydropic degeneration were identified (Fig. Am J Surg Pathol. Am J Surg Pathol. This is a complication usually occurs in pregnancy. Reports of leiomyoma with marked cystic degeneration have been relatively uncommon (Aydin et al., 2013). Red Degeneration: This is due to hemorrhagic infaction of a leiomyoma. reviewed 20 cases of cotyledonoid dissecting leiomyoma . Submucosal: present benath the endometrium. The most common abnormalities are translocations on chromosome 12; deletion on chromosomes 3q and 7q. Leiomyomas can occur in any age group but more common in 30 to 50 years. 1992 ;16: 26 - 32 . Cystic change, an extreme form of hydropic degeneration is a rare clinical presentation. 2 The uterus can enlarge and may have a lobulated contour. Larger tumors result in various pressure symptoms. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Hyaline degeneration consisting of nodular confluent acellular areas (Fig. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. The present case was uncommon in that it exhibited umbilical endometriosis, an extremely enlarged uterus due to marked hydropic and cystic degeneration of the leiomyomas, and torsion of the pedicle of the right ovarian cyst that had caused sudden pain in the right lower abdomen.
