Introduction: Angiomatosis is a rare and benign vascular lesion which can be located in various sites throughout the body, most commonly diagnosed in females in the first two decades of life. Presentation of case: A 54-year-old female with no previous medical history presented with significant pain and discomfort associated with a 12.3 × 11.3 × 4.4 cm posterior chest wall mass invading the 4th and 5th ribs and extending into the thoracic cavity. Discussion: Angiomatosis is a benign vascular lesion that can affect any soft tissue in the body. Typically, it has a female predilection and tends to involve the lower extremities. It is histologically characterized by a proliferation of blood vessels of varying sizes and has a high recurrence rate after excision. Significant blood loss can occur during resection. Conclusion: Management of these lesions is challenging based on the infiltrative and vascular nature of the disease. Neoadjuvant therapy can be considered in select cases. Close surveillance is recommended due to high rates of recurrence.
