Gorham-Stout disease and multiple cervical lymphangiomas: case report.

Introduction: Gorham-Stout disease is a rare condition characterized by extensive bone loss due to the proliferation of new vascular and lymphatic structures. It can occur in any bone and cause pathologic fractures with poor bone healing. Complications such as effusions and lymphangiomas can also develop. Gorham-Stout disease pathogenesis is still being studied, and treatment options are limited, but sirolimus has shown promise in stabilizing or reducing symptoms.

Case presentation: We present a case of a 19-year-old male with Gorham-Stout disease, multiple cervical lymphangiomas, and several thoracic complications successfully treated with sirolimus.

Conclusions: Rare lymphatic diseases should be considered as a potential cause in adult patients with bone involvement and multiple cystic lesions in the neck, axillary, or abdominal regions after excluding more common causes. The complexity of diagnosing Gorham-Stout disease should be emphasized.
