Rhabdomyosarcoma (RMS) is a common soft tissue tumor in adults, but RMS's causes and risk factors are unknown. We present a case of a 62-year-old man with RMS who presented with feelings of fullness after meals and vomiting for the previous five months with anorexia and weight loss for four months. He reported feeling a rolling mass in his belly that moves from left to right. He was initially diagnosed with gastric outlet obstruction due to stomach carcinoma. During the surgical operation, we noted the gross appearance was unlike typical adenocarcinoma or lymphoma of the stomach. Histopathological evaluation of the specimen confirmed a diagnosis of primary epithelial RMS of the stomach. When treating RMS, expertise in immunohistochemistry, molecular biology, genetics, or ultrastructure may be necessary. Information on the appropriate laboratory investigations and management protocol is limited, but an early diagnosis can change the course of treatment and improve patient outcomes.

Hypervirulent (hvKp) has attracted increasing attention in recent years. Diabetes and serotype K1 or K2 are risk factors for invasive liver abscess syndrome including liver abscesses and the metastatic complications such as bacteremia, meningitis, endophthalmitis, and necrotizing fasciitis. Simultaneous infections of the liver, lungs, prostate, brain, and eyes are exceedingly rare.

Background: Glomus tumors are rare, benign mesenchymal neoplasms predominantly located in subungual regions of the extremities. Their occurrence in the mandibular region is exceptionally uncommon, presenting unique diagnostic challenges. Only a limited number of submandibular glomus tumors have been documented, leaving their presentation and management largely underexplored.
