Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Uterine leiomyomas are commonly referred to as Fibroids. 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 … 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. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas.

Saeed et al. 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. Cotyledonoid leiomyoma apparently results from a combination of several uncommon growth patterns operating together, including subserosal growth, dissecting growth, and perinodular hydropic degeneration. But can manifest with abnormal uterine bleeding which is more common in submucosal leiomyomas. 3. Hydropic degeneration is characterized by accumulation of oedema fluid with associated collagen deposition presenting with various patterns [5], [6]. 1992 ;16: 26 - 32 .

Click, Also called dissecting cotyledonoid leiomyoma, Sternberg tumor (, Rare benign tumor characterized by extrauterine bulbous growth continuous with a dissecting myometrial component, Dissecting leiomyomas rarely are due to noncotyledonoid variants (, 55 year old woman whose tumor had alarming gross appearance (, 63 year old woman with epithelioid variant (, Multinodular, exophytic congested bulky tumor resembling placenta extends from uterine wall into broad ligament and pelvic cavity, Reddish brown with multiple bulbous processes protruding over uterine surface, Fascicles and nodules of bland smooth muscle cells, prominent hydropic degeneration, No necrosis, no mitotic figures and no atypia. 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. 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. 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. pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. Leiomyoma dissects into myometrium (black arrow) at the cornu; hydropic change is present around smooth muscle bundles (perinodular hydropic degeneration) Edematous change, referred to as hydropic degeneration, is a common form of degeneration seen focally in up to 50% of patients with leiomyoma . Based on the location of the tumor they are categorized as Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors.

Earlier age of menarche and nulliparous women have higher risk. Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. Magnetic resonance imaging (MRI) was performed to further … Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. There are many microscopic variants which include cellular, Leiomyoma with bizzare nuclei, Mitotically active, hydropic, apopletic, lipomatous, epithelioid, myxoid, dissecting leiomyomas etc. Anastomosing thin cord-like arrangements of the leiomyoma cells mimicked the architecture of adenomatoid tumors. Leiomyomas can undergo degeneration, which can result in a variety of sonographic appearances. Only five cases have been reported previously. Leiomyomas can occur in any age group but more common in 30 to 50 years. Uncomplicated leiomyomas are of a heterogeneous echo texture and vary from hypoechoic to hyperechoic, sometimes containing calcifications with acoustic shadowing. These are usually asymptomatic if small and are often incidental finding. 1) was described and distinguished from the interstitial hyaline degeneration that is commonly seen in uterine leiomyomata. Multinodular hydropic leiomyoma (MHL) of the uterus is one of the rarest variants of uterine leiomyomas and can create some diagnostic problems.

They can be single or multiple. This will result in hyper responsivenesness to normal levels of estrogen in adults. 2b). 2) and distinguished from the interstitial edema commonly seen in leiomyomata. The most common abnormalities are translocations on chromosome 12; deletion on chromosomes 3q and 7q. The cut surfaces are well circumscribed, with greywhite and whorled cut surface. Leiomyoma dissects into myometrium (black Most important risk factor is exposure to environmental estrogens before puberty. 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. Polarizing Microscopy Simplified! Gross: They also showed an intravascular luminal growth pattern. Am J Surg Pathol. However, we cannot answer medical or research questions or give advice. Pathology confirmed that the mass was a leiomyoma with hydropic and myxoid degeneration. Hydropic degenerating leiomyomas are characterized by focal accumulation of edema and collagen deposition. Increased awareness of this grossly alarming variant of benign uterine leiomyoma can help avoid overtreatment. Diffuse, perinodular, and other patterns of hydropic degeneration within and adjacent to uterine leiomyomas: problems in differential diagnosis. Marked degrees of hydropic degeneration may have resulted in cystic degeneration, leading to large myometrial cysts. Can cause pressure symptoms due to compression on adjoining structures. This is also referred to as Carneous degeneration. It is critical for ... 1Department of Pathology, KKR Sapporo Medical Center, 6-3–40, Ichijyo, Hiragishi, Toyohira-ku, Sapporo, Hokkaido 062-0931, Japan ... marked hyalinized degeneration and hydropic change (Fig. 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.
