AI Article Synopsis
- Intracranial epidermoid cysts are rare pseudotumors, making up only 0.2%-1.8% of all intracranial tumors, typically found in areas like the cerebellopontine angle.
- These cysts usually grow slowly, are under 2 cm in size, and cases of giant epidermoid cysts larger than 5 cm that invade bone are extremely rare.
- The report discusses a unique case of a giant extradural epidermoid cyst affecting the parietal bone and includes a systematic review of related literature to analyze clinical features and treatment impacts for larger cysts.
Article Abstract
Intracranial epidermoid cyst is a rare pseudotumor of the nervous system, accounting for 0.2%-1.8% of all intracranial tumors. It is usually located in the cerebellopontine Angle or parasellar area, with insipid onset, slow growth and usually less than 2 cm in diameter. Giant epidermoid cysts that invade the bone have rarely been reported in the literature. Herein, we report a case of giant ECs extradural to the parietal bone, penetrating the skull and continuing to expand outward. In addition, a systematic search of four authoritative databases was conducted to collect the relevant reports of giant epidermoid cyst with diameter > 5cm for the first time, and to discuss the clinical and radiographic features of patients with giant epidermoid cyst and the influence of treatment options.

Modern radiotherapy utilizes a broad range of sources of ionizing radiation, both low-dose-rate (LDR) and high-dose-rate (HDR). However, the mechanisms underlying specific dose-rate effects remain unclear, especially for corpuscular radiation. To address this issue, we have irradiated human epidermoid carcinoma A431 cells under LDR and HDR regimes.

The red panda (Ailurus), a rare and endangered mammal native to the Himalayan-Hengduan Mountains, has a specialized bamboo diet. Combining morphological and genomic evidence, red pandas have been classified as and . However, previous studies focused on ecological aspects such as foraging behaviors, habitat use and threats within specific distributions; hence, there is still a gap in quantitative comparative studies on the trophic niches of these two species.

Xanthogranulomatous epithelial tumor (XGET)/Keratin-positive giant cell tumor (KP-GCT) represents a spectrum of recently described neoplasms characterized by a proliferation of distinctive mononuclear cells expressing keratin within a background of osteoclast-like giant cells, mixed inflammatory cells, and a variably prominent xanthogranulomatous component. Recent studies demonstrated a recurrent HMGA2::NCOR2 fusion in many cases. We herein describe a case of XGET/KP-GCT arising in the right femoral head of a 19-year-old male harboring a rare novel HMGA2::COL14A1 fusion.

Article Synopsis
- A 45-year-old man had a scrotal lesion that he had for 25 years and was asymptomatic.
- The lesion was identified as steatocystoma based on its appearance, measuring 20 cm × 10 cm × 8 cm before removal.
- After surgical excision, the pathological examination showed cysts with characteristics similar to hair root sheath epithelium, containing keratin and some calcification.
