Giant cell tumors (GCTs) are a category of benign but locally aggressive tumors that are challenging to treat. GCT topography most often affects the epiphyseal and metaphyseal regions of long bones but rarely flat bones. We report the case of a 35-year-old woman with an aggressive GCT of the right scapula. Unfortunately, the late presentation of this case to the emergency department makes the scapulectomy more difficult to carry out effectively. As this case highlights, the lack of access to primary care and the lack of available family physicians in the community remains detrimental to good medical care in systems with limited resources.

Pigmented villonodular synovitis (PVNS) is rare in the shoulder, with few descriptions in the literature. We present the case of a 58-year-old female patient with no history of trauma. The patient reported pain for 2 months with no limb irradiation and presented lifting strength loss and progressive limitation of active and passive mobility.

Dermal fillers such as hyaluronic acid (HA) have been widely used in recent years as a less surgically invasive cosmetic treatment. Although delayed foreign body granuloma may occur as a rare adverse reaction after the procedure, detailed histological reports are still limited. When occurring on the buccal mucosa of the oral cavity, the histopathology may resemble some lesions of minor salivary gland origin due to the material properties of HA.

Antiphospholipid syndrome (APS) is associated with recurrent pregnancy morbidity, yet the underlying mechanisms remain elusive. We performed multifaceted characterization of the biological and transcriptomic signatures of mouse placenta and uterine natural killer (uNK) cells in APS. Histological analysis of APS placentas unveiled placental abnormalities, including disturbed angiogenesis, occasional necrotic areas, fibrin deposition, and nucleated red blood cell enrichment.

Objective: To investigate differences in arterial involvement patterns on F-FDG PET-CT between predominant cranial and isolated extracranial phenotypes of giant cell arteritis (GCA).
Methods: A retrospective review of F-FDG PET-CT findings was conducted on 140 patients with confirmed GCA. The patients were divided into two groups: the cranial group, which presented craniofacial ischemic symptoms either at diagnosis or during follow-up, and the isolated extracranial group which never exhibited such manifestations.

Giant cell arteritis (GCA) is a primary systemic vasculitis affecting the elderly, characterized by a granulomatous vessel wall inflammation of large- and medium-sized arteries. The immunopathology of GCA is complex, involving both the innate and adaptive arms of the immune system, where a maladaptive inflammatory-driven vascular repair process ultimately results in vessel wall thickening, intramural vascular smooth muscle cell proliferation, neovascularization and vessel lumen occlusion, which can lead to serious ischemic complications such as visual loss and ischemic stroke. Over the past decade, microRNA (miRNA) dysregulation has been highlighted as an important contributing factor underlying the pathogenesis of GCA.
