Abstract

Giant Cell Tumor (GCT) is a primary neoplasm that is intermediate malignant, characterized by aggressive local growth and the possibility of metastasis, especially to the lungs. Giant Cell Tumor (GCT) occurs in bones, tendons, and soft tissues. The purpose of this literature study is to identify differences in GCT manifestations in various anatomical locations, evaluate risk factors that contribute to tumor growth and recurrence, and assess the effectiveness of various therapeutic modalities that have been used, both conservative and operative. The method used is a literature study by reviewing various scientific journals obtained from the database. The findings show that Giant Cell Tumor (GCT) is a group of neoplasms that are histologically similar but have different clinical, molecular characteristics, and anatomical locations, including GCT in bones (GCTB), tendons (GCTTS), and soft tissues (GCTST). Although generally classified as benign, GCT can be locally aggressive with a risk of recurrence and in some cases is capable of metastasis, especially to the lungs. GCTB is most commonly found in the long bones of individuals aged 20–40 years and is characterized by the H3F3A mutation, which is an important diagnostic marker. GCTTS, which originates in the synovium, is more common in women aged 30–50 years and shows increased CSF1 expression due to a genetic translocation.

Abstract

Decompression illness (DCI) encompasses two major diving-related disorders: decompression sickness (DCS) and arterial gas embolism (AGE). Both conditions are characterized by the formation of gas bubbles that act as the primary mechanism of tissue injury, resulting in overlapping clinical manifestations and similar therapeutic approaches. This study aims to review the pathophysiology, clinical presentation, diagnosis, and management of DCI that presents with stroke-like neurological symptoms. The method used was a literature review approach based on current evidence from recent scientific publications. Findings show that DCS occurs when dissolved inert gases, such as nitrogen, become supersaturated during ascent and form bubbles within tissues and the venous circulation. AGE typically arises from pulmonary barotrauma, allowing trapped gas to enter the pulmonary veins and reach the arterial circulation, with the brain as the most vulnerable target organ. DCI is considered a medical emergency requiring definitive management with hyperbaric oxygen therapy (HBOT). Neurological manifestations of DCI often resemble conventional ischemic stroke but demonstrate distinct clinical and temporal patterns related to pressure changes. Therefore, in addition to recompression therapy, patients may require standard acute stroke management. Prognosis depends heavily on the promptness of diagnosis and treatment, as early intervention is critical to preventing permanent neurological injury.
