We report a case of a 58-year-old woman with a history of cutaneous melanoma in situ excised 26 years ago, now presenting with a 3-month history of abdominal symptoms, melena, and weight loss. Work-up revealed anemia and positive occult blood, with negative gastroscopy and colonoscopy. CT confirmed jejuno-jejunal intussusception, and enteroscopy identified multiple pigmented lesions. Biopsy confirmed malignant melanoma, and PET-CT showed multifocal involvement. The patient underwent laparotomy with bowel resection and jejunostomy, followed by immunotherapy, leading to complete tumor resolution and no recurrence on follow-up PET-CT.

This case study explores a 35-year-old woman in her second trimester of a twin pregnancy with a history of gestational diabetes mellitus and pregnancy-induced hypertension. She was referred for a urinary tract infection (UTI) caused by Klebsiella pneumoniae. Initial treatments with erythromycin and sulbactam/cefoperazone were ineffective, leading to the use of ceftriaxone. A skin test revealed severe hypersensitivity to ceftriaxone from one manufacturer (\"Brand A\") but not to another (\"Brand B\"). After careful consideration, a 10-day course of parenteral ceftriaxone from Brand B was administered without adverse reactions. The observed variability in hypersensitivity reactions between different brands of ceftriaxone highlights the potential influence of formulation differences on patient tolerance. This underscores the importance of individualized patient assessment, including skin testing necessary, to ensure both safety and efficacy, particularly in high-risk populations such as pregnant patients. This finding emphasizes the necessity for skin testing in pregnant patients where treatment options are limited and both maternal and fetal safety are paramount.</div></div>","PeriodicalId":100908,"journal":{"name":"Medical Reports","volume":"13 ","pages":"Article 100263"},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144185443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endoscopies were unremarkable till a study done during an active episode demonstrated volvulus. This highlights the importance of high suspicion amongst surgical cases since the endoscopic studies are non-revealing outside of the episode.

Somatic variants in DNMT3A have been widely studied in different types of tumors, including acute myeloid leukemia, hematopoietic and lymphoid cancers. This report describes the case of a 37-year-old male with clinical features of MPD and heterozygous for a variant in the DNMT3A gene, c.911_913del:p.(Ser304del) in exon 8, who presented with severe weight loss and dysphagia and found with two synchronous distinct masses in the epiglottis and upper esophagus. Endoscopy guided biopsies of the epiglottic mass showed a poorly differentiated squamous cell carcinoma (SCC), and esophageal biopsy was consistent with a well to moderately differentiated SCC with keratinization. Next Generation sequence analysis (NGS) of both cancers showed overlapping pathways involving TP53 and MUTYH and similar PD-L1 combined positive score (CPS). The patient was treated with palliative radiation according to the Quad Shot regimen on the epiglottic and esophageal masses. Unfortunately, he deteriorated rapidly, and the family decided to transition to hospice care. This is the first case of a patient with clinical features of MPD and heterozygous for an in-frame deletion of DNMT3A, developing two synchronous cancers.</div></div>","PeriodicalId":100908,"journal":{"name":"Medical Reports","volume":"13 ","pages":"Article 100259"},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
