Non-Hodgkin's lymphoma (NHL) is a common cause of Fever of Unknown Origin (FUO) but the presentation as a gynaecologic malignancy is exceedingly rare. To our knowledge, this represents the first report of an intravascular large B-cell lymphoma of the uterus presenting with fever of unknown origin. After a standard clinical work-up for FUO, the endometrial curettage directed by the finding of a localized fluoro-deoxyglucose Positron Emission Tomography (FDG-PET) hot spot in the pelvic area, yielded material revealing an intr avascular B-cell lymphoma. A total abdominal hysterectomy confirmed the presence of an intravascular large B-cell lymphoma in the lumina of small blood vessels of the uterus.
BackgroundGastrointestinal metastasis from primary breast carcinoma is uncommon, anorectal involvement is extremely rare.Case presentationWe present the case of a 65-year old woman who underwent treatment for an infiltrative lobular carcinoma of the left breast with bone metastases and who developed metastasis of the rectum and anal canal 4 years later.ConclusionsA patient with a history of breast cancer, especially lobular carcinoma, presenting with anorectal symptoms, should raise the suspicion of metastatic disease.
Uterine adenosarcoma (UAS) is microscopically characterized by a biphasic growth pattern. By definition, the epithelial component is benign, whereas the stromal component typically has the appearance of a low-grade sarcoma, usually an endometrial stromal sarcoma. CD10 acts by reducing cellular response to peptide hormones and is currently regarded as a specific marker for endometrial stromal tumors. In this international multicenter study, we further explored CD10 immunoreactivity in 30 UASs. We encountered CD10 positivity of the sarcomatous component in 18/20 (90%) of UASs, in five of eight (63%) of UASs with sarcomatous overgrowth as well as in both cases of recurrent UAS. The epithelial component stained negative in all cases. These findings suggest that CD10 can be used to differentiate UAS from cellular leiomyoma, or in case endometrial stromal cells exhibit muscle differentiation. Furthermore, CD10 positivity in recurrent UAS might guide the pathologist toward an endometrial stromal origin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
