IntroductionThe ovary is a common site of metastasis from various organs. However, little is known about gallbladder carcinoma metastasizing to the ovaries and presenting as a primary ovarian tumor.Case presentationWe report two cases of a metastatic gallbladder carcinoma which mimicked a primary ovarian tumor in a 35-year-old and a 62-year-old North Indian woman. Clinically, both our patients presented with abdominal masses without obvious signs and symptoms related to gallbladder carcinoma. Radiology suggested the possibility of a primary ovarian tumor with chronic cholecystitis and cholelithiasis. The gross features also mimicked a primary malignant ovarian tumor in the first case and a benign mucinous neoplasm in the second case. Exact diagnoses could only be made after thorough sampling from both the ovaries and gallbladder.ConclusionsGallbladder carcinoma with metastasis to the ovaries can mimic both malignant and benign primary ovarian tumors. Extensive cystic change in the ovary due to metastasis from gallbladder carcinoma has rarely been reported. A high index of suspicion and thorough sampling are essential to avoid misdiagnosis in such cases.
Bis(3-amino-1-hydroxybenzyl)diselenide containing two ortho groups was synthesized from 7-nitro-3H-2,1-benzoxaselenole and in situ generated sodium benzene tellurolate (PhTeNa). One-pot synthesis of 1,3-benzoselenazoles was achieved from bis(3-amino-1-hydroxybenzyl)diselenide and aryl aldehydes using acetic acid as a catalyst. The X-ray crystal structure of chloro-substituted benzoselenazole revealed a planar structure with T-shaped geometry around the Se atom. Both natural bond orbital and atoms in molecules calculations confirmed the presence of secondary Se···H interactions in bis(3-amino-1-hydroxybenzyl)diselenide and Se···O interactions in benzoselenazoles, respectively. The glutathione peroxidase (GPx)-like antioxidant activities of all compounds were evaluated using a thiophenol assay. Bis(3-amino-1-hydroxybenzyl)diselenide and benzoselenazoles showed better GPx-like activity compared to that of the diphenyl diselenide and ebselen, used as references, respectively. Based on 77Se{1H} NMR spectroscopy, a catalytic cycle for bis(3-amino-1-hydroxybenzyl)diselenide using thiophenol and hydrogen peroxide was proposed involving selenol, selenosulfide, and selenenic acid as intermediates. The potency of all GPx mimics was confirmed by their in vitro antibacterial properties against the biofilm formation of Bacillus subtilis and Pseudomonas aeruginosa. Additionally, molecular docking studies were used to evaluate the in silico interactions between the active sites of the TsaA and LasR-based proteins found in Bacillus subtilis and Pseudomonas aeruginosa.
IntroductionInvolution of lactation is a physiological process. Rarely, it may be delayed and troublesome for the lactating woman. Though lactation-induced changes in breast are well known, morphological features of delayed involution are not clear.Case presentationWe report a case of a 22-year-old lactating mother who presented with a painful, non-resolving breast mass 5 months after delivery. Clinically, it simulated an inflammatory carcinoma. Histopathology, however, revealed involuting lactational changes.ConclusionTo the best of our knowledge, lactational involution with such a presentation has not been described in the English literature. The case needs to be reported so that this entity can be considered among the differential diagnoses of breast masses in a lactating patient.
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.
