Am J Surg Pathol. 2b). 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 … Most important risk factor is exposure to environmental estrogens before puberty. Submucosal: present benath the endometrium. Saeed et al. 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. Occasionally uterine tumors may detach and results in a rare type called PARASITIC leiomyoma. 2. Microscopy: the pattern is that of interlacing fascicles or whorling of smooth muscle cells. Polarizing Microscopy Simplified! Intramural: within the myometrium. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. These are usually asymptomatic if small and are often incidental finding. A presumed direct relation between the abundance of intratumoral fluid and presence of ascites seemed justified. Diffuse hydropic degeneration is considered much less common and may result in exceptionally large tumors, depending on the degree of fluid accumulation . Marked degrees of hydropic degeneration may have resulted in cystic degeneration, leading to large myometrial cysts. This will result in hyper responsivenesness to normal levels of estrogen in adults. Hyaline degeneration consisting of nodular confluent acellular areas (Fig. Hydropic changes lead to formation of cystic cavities. This website is intended for pathologists and laboratory personnel but not for patients. Etiology: Exact etiology is not known, however age of menarche and parity are important risk factors.

Roth, Department of Pathology, University Hospital, Room 3465, 550 North University Boulevard, Indianapolis, IN 46202-5280, U.S.A. ... and one was a multinodular leiomyoma with hydropic degeneration. The most common abnormalities are translocations on chromosome 12; deletion on chromosomes 3q and 7q. Pathology confirmed that the mass was a leiomyoma with hydropic and myxoid degeneration. 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. Ovary tumor - Leiomyoma. Cytogenetic abnormalities: 40 to 50% of uterine leiomyomas show karyotypic abnormalities. Leiomyomas can undergo degeneration, which can result in a variety of sonographic appearances. 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 … Uncomplicated leiomyomas are of a heterogeneous echo texture and vary from hypoechoic to hyperechoic, sometimes containing calcifications with acoustic shadowing. Background: Leiomyomas rarely cause pseudo-Meigs syndrome. Uterine leiomyomas are commonly referred to as Fibroids. Author information: (1)Department of Pathology, NKP Salve Institute of Medical Sciences and Research Centre, Nagpur. Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. Subserosal they are seen beneath the serosa. They can also interfere in fertility. 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. Specifically, a rapidly growing uterine mass is not a reliable predictor of leiomyosarcoma according to Parker et al. 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.

Geographic areas of hydropic degeneration were identified (Fig. The tumor cells were positive for the microphthalmia transcription factor but negative for other melanoma markers. Cotyledonoid hydropic intravenous leiomyomatosis: a new variant leiomyoma. Hyalinization is the commonest type of degeneration. Ultrasonography (US) showed a heterogeneous abdominopelvic mass. pathology examination confirmed that the mass was a leiomyoma with hydropic and cystic degeneration. Myxoid degeneration in a huge uterine leiomyoma: an unusual benign pathology mimiking malignancy 117 Fig. is present around smooth muscle bundles Perinodular hydropic degeneration of a uterine leiomyoma is a rare form of the more common hydropic change observed in leiomyomas. Uterine Leiomyoma: These are the benign tumors of smooth muscle of uterus. Pathology When the leiomyomas increase in size, the vascular supply to it becomes inadequate and leads to different types of degeneration which are hyaline, cystic, myxoid, or red degeneration and dystrophic calcification may also occur. This is a complication usually occurs in pregnancy. 4. Pedunculated: Submucosal and subserosal tumors can be pedunculated with the presence of narrow pedicle. There are no clinical findings that reliably differentiate ordinary leiomyomas from leiomyoma variants and leiomyosarcomas.
