IgG4-related disease has been previously described to involve numerous organs and anatomic sites, however, involvement of the ovary has not yet been reported in the literature. In this case report we describe an ovary involved with an inflammatory process with histopathologic features supportive of involvement by IgG4-related disease: a dense lymphoplasmacytic infiltrate with an eosinophilic component, obliterative phlebitis, and a prominent proportion of IgG-positive cells with IgG4 expression by immunohistochemistry (40%-50%). The differential diagnosis for this case would include eosinophilic perifolliculitis involving the ovary, another rare entity that shares the eosinophilic component of IgG4-related disease. In short, we present the first description of IgG4-related disease of the ovary providing morphologic characterization and immunohistochemical studies supporting the diagnosis.

We report a case of an elderly female with subacute submental neck swelling, dry cough, and a history of significant weight loss. Unexpectedly, a left submandibular chronic sialadenitis was noted on ultrasound of the neck, along with a thyroid nodule that, on biopsy, showed lymphocytic infiltration. High-resolution computed tomography of the lungs revealed multifocal irregular consolidations with lymphadenopathy, and possible infective causes, including tuberculosis, were ruled out after a thorough microbiological evaluation.

Background: Prolonged SARS-CoV-2 infection observed in immunocompromised individuals even in the presence of antiviral treatment provides opportunities for viruses to evolve in immune escape and drug-resistant variants.
Case Presentation: A 72-year-old male with IgG4-related disease was admitted to the Emergency Department of a city Hospital in Milan and then transferred to Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico in December 2023, due to respiratory distress due to SARS-CoV-2 infection diagnosed in November 2023. After 117 days since the onset of the infection, and two cycles of sotrovimab/remdesivir combined therapy, the clinical improvement allowed the hospital discharge, notwithstanding the persistent SARS-CoV-2 positivity.

Objective To analyze the value of abdominal CT images combined with serological indicators in predicting the ureteral involvement in idiopathic retroperitoneal fibrosis(IRF). Methods The CT images of 79 IRF patients were analyzed retrospectively,including the involved sites and enhancement characteristics of the lesions.According to the inclusion and exclusion criteria,43 patients with complete serological data were selected and assigned into a ureteral involvement group(=29)and a non-ureteral involvement group(=14) according to whether ureters were involved in IRF.

We report a case of a 66-year-old woman with 8 years of progressive bilateral periorbital fullness, eyelid edema, and skin laxity. She had a history of thyroid cancer, smoldering myeloma, and systemic amyloidosis. The exam demonstrated significant bilateral periorbital fullness with mild limitation of extraocular motility in all directions bilaterally without double vision.
