Gorham-Stout Disease (GSD) is a rare lymphatic disorder affecting children or young adults with no predilection of sex. It is generally associated with vanishing bone osteolytic lesions, thoracic and abdominal involvement, and diffuse pulmonary lymphangiomatosis. Chylous effusions and chylothorax, consequent to the abnormal proliferation of lymphatic vessels, may induce respiratory failure with a high mortality risk. Extrapulmonary alterations may include chylous ascites, lymphopenia, and destructing bone disease for overgrowth of lymphatic vessels. Here, we report the case of a young woman who developed a severe and recalcitrant GSD with persistent unilateral chylothorax during pregnancy. The complex management of this patient during and after pregnancy was discussed and compared with literature data to contribute to the definition of a correct diagnostic and therapeutic approach to this rare lymphatic disease.

Background: Gorham-Stout disease (GSD) is a rare disease characterized by osteolysis and lymphatic malformations. GSD involving the spine is exceptionally rare and lacks a standard cure. The aim of this article was to report a case of GSD with scoliosis treated via corrective surgery and medication.

Case: This is a case of a 6-year-old patient diagnosed with Gorham-Stout disease (GSD), a rare lymphangiogenic skeletal disorder, localized to the left femur. Initial nonoperative treatment with pharmaceuticals and bracing was unsuccessful. We describe a definitive operative treatment with radical femoral resection and a modified rotationplasty technique through a tibiopelvic rotational hip arthroplasty.

Purpose: The polarization of macrophages towards the pro-inflammatory M1 phenotype and osteoclast overactivation play a significant role in the pathogenesis of aseptic loosening of orthopedic implants. This study sought to examine the expression and activation of macrophages and osteoclasts in implant biopsies with respect to epidermal growth factor receptor (EGFR) signaling and to assess the potential of EGFR inhibition in mitigating titanium particle-induced bone resorption in a cranial resorption murine model.
Methods: Bone marrow-derived macrophages (BMDMs) were stimulated with Tumor Necrosis Factor-alpha (TNF-α) and Interferon-gamma (IFN-γ) initially.

Genetically targeted medications are emerging as important therapies for lymphatic malformations (LMs) unresponsive to sirolimus. We describe two patients with EML4::ALK-positive LMs, one with Gorham Stout disease and one with a large genitourinary (GU) LM, who were successfully treated with ALK inhibitors. This report adds ALK inhibitors to the growing toolbox of molecularly targeted therapies for LMs.

Osteoclasts are terminally differentiated multinucleated giant cells that mediate bone resorption and regulate skeletal homeostasis under physiological and pathological states. Excessive osteoclast activity will give rise to enhanced bone resorption, being responsible for a wide range of metabolic skeletal diseases, ranging from osteoporosis and rheumatoid arthritis to tumor-induced osteolysis. Therefore, the construction of in vitro models of osteoclast-mediated bone resorption is helpful to better understand the functional status of osteoclasts under (patho)physiological conditions.
