Key result
Repeated surgery and radiotherapy fail to halt metastatic progression of primary abdominal wall angiosarcoma.
Why the study?
Angiosarcoma is an aggressive vascular malignancy with nonspecific clinical features that often mimic benign conditions, leading to delayed diagnosis.
Case Report (n=1)
This case highlights the aggressive clinical course of primary abdominal wall angiosarcoma, its propensity for local recurrence and distant metastasis, and the diagnostic challenges posed by its variable presentation.
Underscores need for vigilant surveillance after resection in abdominal wall angiosarcoma; leaves open optimal multimodal strategies.
Angiosarcoma is an uncommon and aggressive vascular malignancy that may present with nonspecific clinical features, often mimicking benign conditions and leading to delayed diagnosis. We present a case of a 74-year-old man who presented with a progressively enlarging lesion of the anterior abdominal wall, initially presumed to be a hematoma. Imaging revealed subcutaneous lesions, and surgical excision was performed. Gross examination demonstrated a fungating gray-tan mass with surrounding areas of hemorrhagic discoloration. Histopathologic evaluation revealed a high-grade, poorly differentiated angiosarcoma involving the dermis and subcutaneous tissue, characterized by markedly atypical endothelial cells forming irregular vascular channels, as well as solid and spindle cell areas with numerous mitotic figures. Following initial resection, the patient developed local recurrence requiring multiple subsequent surgical excisions. Despite multimodal management, including repeated surgeries and radiotherapy, the disease progressed, with the development of metastatic lesions involving musculature and bone. Systemic chemotherapy was initiated upon progression. This case highlights the aggressive clinical course of angiosarcoma, its propensity for local recurrence and distant metastasis, and the diagnostic challenges posed by its variable presentation. Early recognition, histopathologic confirmation, and a multidisciplinary approach are essential for optimal management.

Rivera-Díaz et al. (2026) conducted a case report in Primary Abdominal Wall Angiosarcoma (n=1). Multimodal management (surgery, radiotherapy, chemotherapy) was evaluated. A 74-year-old man with primary abdominal wall angiosarcoma developed local recurrence and metastatic progression to musculature and bone despite repeated surgical excisions and radiotherapy.
