A 15-year-old girl presented with pain in the right ear and acute onset of total peripheral facial nerve palsy. Imaging studies revealed an intracranial mass of the right temporal bone causing temporal lobe displacement. A first biopsy led to the diagnosis of intracranial giant cell reparative granuloma (GCRG), a rare benign tumor of the bone or soft tissue that can show expansive growth. The etiology of GCRG is unclear. Facial nerve palsy responded to treatment with diclofenac and physiotherapy, however, the intracranial lesion progressed at follow-up. Total surgical excision revealed a cholesteatoma central to the GCRG originating from the right middle ear and mastoid. Cholesteatoma should be considered as a trigger for intracranial GCRG growth, especially if adjacent to the temporal bone.

In this article, we report the first case of a 61-year-old woman who was diagnosed with both nodules and cystic lesions in her lungs. The lung nodules were diagnosed as ALK-positive histiocytosis (APH) carrying an gene fusion, which microscopically displayed a mixed morphology of foamy cells, spindle cells, and Touton's giant cells. Immunohistochemistry showed expression of CD163, CD68, and ALK, while fluorescence hybridization (FISH) with second-generation sequencing (NGS) showed the ALK gene fusion with the FLCN gene variant.

Background: Cardiovascular involvement is a rare but severe complication of Epstein-Barr virus (EBV) infections. Patients with chronic active EBV (CAEBV) are at increased risk of developing cardiovascular complications and have a poor prognosis. Here, we report the rare case of a pediatric patient with CAEBV and EBV- hemophagocytic lymphohistiocytosis (HLH) complicated with a giant coronary artery aneurysm (CAA) and thrombosis, a giant Valsalva sinus aneurysm, and ascending aorta dilation seven years after the disease onset.

This case report describes a 20-year-old male student from Bahdo City, Somalia, who presented with a persistent cervical mass following a history of trauma. The patient exhibited vital signs within normal limits, and imaging studies, including ultrasound and computed tomography, revealed well-defined cystic masses.

Transgenerational plasticity in plants is an increasingly recognized phenomenon, yet it is mostly unclear whether transgenerational plasticity is relevant to both the fitness of the plant and its interacting species. Using monoclonal strains of the giant duckweed (Spirodela polyrhiza) and its native herbivore, the waterlily aphid (Rhopalosiphum nymphaeae), we assessed whether pre-treating plants with copper excess, both indoors and outdoors, induces transgenerational plasticity in plant defences that alter plant and herbivore fitness. Outdoors, copper pre-treatment tended to increase plant growth rates under recurring copper excess.

Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm, which generally arises from the pleura. There have been documented a number of extrapleural origins including the head and neck in the literature. It is emphasized to make a diagnosis in a rare location such as the retropharyngeal space.
