These are usually multiple with sizes ranging from microscopic foci to large bulky tumors. Microscopy: the pattern is that of interlacing fascicles or whorling of smooth muscle cells. This is a complication usually occurs in pregnancy. Uncomplicated leiomyomas are of a heterogeneous echo texture and vary from hypoechoic to hyperechoic, sometimes containing calcifications with acoustic shadowing. Most important risk factor is exposure to environmental estrogens before puberty. Edematous change, referred to as hydropic degeneration, is a common form of degeneration seen focally in up to 50% of patients with 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. We welcome suggestions or questions about using the website. Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. They also showed an intravascular luminal growth pattern. Am J Surg Pathol. Pathology confirmed that the mass was a leiomyoma with hydropic and myxoid degeneration.

However, we cannot answer medical or research questions or give advice. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. Extensive hydropic degeneration in uterine leiomyoma is a rare occurrence and is commonly reported in association with pregnancy. Increased awareness of this grossly alarming variant of benign uterine leiomyoma can help avoid overtreatment. 2b). Cytogenetic abnormalities: 40 to 50% of uterine leiomyomas show karyotypic abnormalities. Only five cases have been reported previously. 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. These are usually asymptomatic if small and are often incidental finding. Hyaline degeneration consisting of nodular confluent acellular areas (Fig. Leiomyoma dissects into myometrium (black arrow) at the cornu; hydropic change is present around smooth muscle bundles (perinodular hydropic degeneration) Multinodular hydropic leiomyoma (MHL) of the uterus is one of the rarest variants of uterine leiomyomas and can create some diagnostic problems. 3. Leiomyomas can undergo degeneration, which can result in a variety of sonographic appearances. Cotyledonoid dissecting leiomyoma is an extremely rare variant of uterine leiomyoma with an unusual growth pattern characterized by an extrauterine mass that resembles a placenta and histologically shows an intramural dissecting pattern in the uterus [2, 3]. Earlier age of menarche and nulliparous women have higher risk. Genes involved : HGMA2, ESR2, RAD5 & MED12, Clinical features: Leiomyoma dissects into myometrium (black A variety of unusual growth patterns can occur in uterine leiomyomas, such as diffuse uterine leiomyomatosis, disseminated peritoneal leiomyomatosis, benign metastasizing leiomyoma, parasitic leiomyoma, intravascular leiomyomatosis, dissecting leiomyoma, and leiomyoma with perinodular hydropic degeneration.1 In 1996, Roth et al2 reported a series of 4 cases of leiomyoma characterized … Uterine leiomyomas are commonly referred to as Fibroids. Table 1 summarizes ordinary leiomyomas, including their various forms of degeneration, and their main variants. 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. Subserosal they are seen beneath the serosa. Etiology: Exact etiology is not known, however age of menarche and parity are important risk factors. Diffuse hydropic degeneration is considered much less common and may result in exceptionally large tumors, depending on the degree of fluid accumulation . 1992 ;16: 26 - 32 . 2 The uterus can enlarge and may have a lobulated contour. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. The common cause is due to obstruction of venous drainage at the periphery of the lesion. But can manifest with abnormal uterine bleeding which is more common in submucosal leiomyomas. The patient was admitted in the emergency department because of diffuse abdominal bloating and discomfort. pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. A presumed direct relation between the abundance of intratumoral fluid and presence of ascites seemed justified. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. These are the ones which can manifest with menorrhagia. The common cause is due to obstruction of venous drainage at the periphery of the lesion. 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. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. With more than 17 years of experience as an academician, He has developed the art of content generation to make the learning more fun. Hydropic degenerating leiomyomas are characterized by focal accumulation of edema and collagen deposition. Huge leiomyoma with myxoid degeneration (cystic spaces) on cut section It is a close mimicker of malignancy due to rapid growth and atypical imaging appearances. 1. Background: Leiomyomas rarely cause pseudo-Meigs syndrome. Morphology: Red Degeneration: This is due to hemorrhagic infaction of a leiomyoma. Aims: We present the histopathological findings of a series of six cases of a benign uterine smooth muscle tumour with an unusual growth pattern.. Methods and results: All cases have the appearances of the recently described dissecting (cotyledonoid) leiomyoma.In addition, three of these lesions demonstrate the … Gross: 2. 1) was described and distinguished from the interstitial hyaline degeneration that is commonly seen in uterine leiomyomata. Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. Obesity, lack of exercise are also risk factors for development of leiomyomas. This is also referred to as Carneous degeneration. 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 … Intramural: within the myometrium. Larger tumors result in various pressure symptoms. Submucosal: present benath the endometrium. arrow) at the cornu; hydropic change If the tumor is very large, the degenerative changes can be seen. 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. Marked degrees of hydropic degeneration may have resulted in cystic degeneration, leading to large myometrial cysts. Microscopically, the nodules were separated by extensive hydropic degeneration. Reports of leiomyoma with marked cystic degeneration have been relatively uncommon (Aydin et al., 2013). 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 … The tumor cells were positive for the microphthalmia transcription factor but negative for other melanoma markers. Most often asymptomatic.

Cotyledonoid hydropic intravenous leiomyomatosis: a new variant leiomyoma. Hydropic degeneration is characterized by accumulation of oedema fluid with associated collagen deposition presenting with various patterns [5], [6]. Abstract. Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. This will result in hyper responsivenesness to normal levels of estrogen in adults. The nodules were composed of cigar-shaped spindle cells with no mitosis, cellular pleomorphism or coagulation necrosis. No striated muscle tissues were noted between the tumor and resection margin, but a thin smooth muscle layer, positive for hormone receptors, was present at the periphery, suggesting the origin of the tumor. reviewed 20 cases of cotyledonoid dissecting leiomyoma . This website is intended for pathologists and laboratory personnel but not for patients. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Highly cellular variant and lipoleiomyomas will be yellowish in color. They can also interfere in fertility. Increased levels of CA 125 often are associated with some types of malignancy. Hyalinization is the commonest type of degeneration. Diffuse, perinodular, and other patterns of hydropic degeneration within and adjacent to uterine leiomyomas: problems in differential diagnosis. This is a complication usually occurs in pregnancy. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. leiomyoma might have a unique clinical presentation involving concomitant uterine adenomyosis. The incidence decreases after menopause. They are most common tumors in females. The individual smooth muscle cells are uniform in size and shape and have characteristic oval to elongated with blunt ends ( CIGAR shaped). Cystic degeneration is an extreme sequel of edema. Hydropic changes lead to formation of cystic cavities. The cut surfaces are well circumscribed, with greywhite and whorled cut surface. 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.
