RESUMEN
BACKGROUND: Herpes zoster is a common disease that can affect men and women at any age. Sensory neuropathy is the most common complication while motor neuropathy of the abdominal muscles is rare complication appearing in ~ 0.7% of patients. Furthermore, visceral nerve involvement causing gastroparesis is an extremely rare postherpetic complication. We present an extremely rare case of acute gastric dilatation with segmented abdominal paresis as a rare manifestation of herpes zoster infection. CASE PRESENTATION: A 91-year-old Asian man was admitted to hospital with 2-day history of vomiting and left abdominal protrusion. He was previously treated for a rash on the left abdominal wall as herpes zoster infection with oral valaciclovir 2 weeks prior. On physical examination, characteristic herpes zoster rash scars and an ipsilateral abdominal bulge were observed on the left side. Computed tomography revealed no abdominal wall defect, mass, or stenosis. Remarkable distension of the stomach, asymmetrical left flank wall bulge, and a thinner abdominal wall on the left compared with the right side were shown. He was diagnosed as acute gastric dilatation owing to gastroparesis and segmental paresis of the abdominal musculature associated with herpes zoster infection. The patient showed significant improvement in symptoms and abdominal paresis within a month of conservative treatment, including nasogastric tube decompression and mosapride administration. CONCLUSION: Acute gastric dilatation with abdominal paresis is an extremely rare complication of herpes zoster infection, and to date there have been no reports in the literature. It alerts us that, when examining patients with abdominal bulge, we should be conscious of this rare pathology for the optical diagnosis, avoiding unnecessary invasive examination or surgical exploration.

BACKGROUND Essential thrombocytosis (ET) is a myeloproliferative neoplasm variant that leads to excessive platelet production in the bone marrow. Janus kinase 2 (JAK2) mutation is observed in 60% of ET cases. The risk of thrombosis increases with the presence of this mutation. ET can cause systemic thrombosis, including extra-portal vein thrombosis (EHPVT). In patients with ET-induced EHPVT, varied symptoms generally occur. However, our case was asymptomatic. This condition is relatively rare. CASE REPORT A 49-year-old woman presented to our hospital for a detailed clinical examination 1 month after a health examination, and blood tests revealed microcytic anemia and thrombocytosis. The patient had no current concerns and had no relevant medical or alcohol consumption history. Esophagogastroduodenoscopy demonstrated esophageal varices, with portal hypertension suspected as the underlying cause. Contrast-enhanced computed tomography scans revealed a thrombus in the portal vein, but liver cirrhosis and a tumor were ruled out. JAK2 mutation was positive, which led to myeloproliferative neoplasms being considered as the differential diagnosis. Bone marrow biopsy demonstrated many mature megakaryocytes with large and irregular nuclei and platelet aggregation in the field of view, leading to the diagnosis of ET. CONCLUSIONS This case study describes a patient with EHPVT caused by JAK2-positive ET. This case report emphasizes that physicians should consider myeloproliferative neoplasms as part of their differential diagnosis when presented with EHPVT.

BACKGROUND: Phlegmonous gastritis is a rare and fatal infectious disease of the stomach, presenting varied and nonspecific endoscopic images, which are therefore difficult to diagnose. This report discusses three cases of phlegmonous gastritis, each with unique endoscopic images, and considers the differential diagnosis of this disease. These cases were initially suspected of scirrhous gastric cancer, gastric syphilis, and acute gastric mucosal lesion. CASE PRESENTATION: Case 1 A 32-year-old Asian man visited our hospital complaining of upper abdominal pain. Endoscopy raised suspicion of scirrhous gastric cancer. However, a histopathological examination showed no malignant cells, thus leading to the diagnosis of phlegmonous gastritis. The patient was started on antibiotic therapy, which was effective. Case 2 A 33-year-old Asian man visited our hospital complaining of epigastralgia. Endoscopy raised suspicion of gastric syphilis. However, the serum test for syphilis was negative, and Streptococcus viridans was detected in the biopsy specimen culture, which led to the diagnosis of phlegmonous gastritis. The patient was started on antibiotic therapy, resulting in significant improvement in the endoscopic image after 2 weeks. Case 3 A 19-year-old Asian man visited our hospital complaining of epigastric pain. Endoscopy raised suspicion of acute gastric mucosal lesion. A gastric juice culture showed Pseudomonas aeruginosa and Streptococcus viridans, thus leading to the diagnosis of phlegmonous gastritis. The patient was started on antibiotic therapy, resulting in the disappearance of the gastric lesions. CONCLUSION: In severe cases of phlegmonous gastritis, immediate surgical treatment is generally required. However, the endoscopic images are varied and nonspecific. These three cases suggest that clinicians need to consider the differential diagnosis of phlegmonous gastritis and make accurate diagnoses at an early stage.

Herpes simplex esophagitis (HSE) occurs mostly in immunocompromised patients and rarely in immunocompetent patients. We encountered an elderly patient, a biologically immunocompromised patient with HSE who had characteristic endoscopic features and responded to acyclovir therapy. An 82-year-old woman presented with high-grade fever and epigastric discomfort for several days. A diagnosis of bacterial pneumonia was made based on imaging studies and cultures. Despite antibiotic treatment, epigastric discomfort persisted. Endoscopy revealed multiple exudative and circumscribed shallow ulcers with slightly raised edges in the mid-distal esophagus. Esophageal biopsy specimens showed multinucleated giant cells with Cowdry type A intranuclear inclusion bodies in epithelial cells, which were positive for herpes simplex virus-type 1 DNA by polymerase chain reaction. Because a diagnosis of HSE was made, she was treated with acyclovir, resulting in esophageal mucosal healing. In elderly patients with esophageal symptoms, HSE should be considered.
