Intravascular Papillary Endothelial Hyperplasia (IPEH) is a rare benign vascular lesion of the skin and subcutaneous tissues that results from the proliferation of endothelial cells within a blood vessel. In this article, we present the case of an IPEH mimicking a Sister Mary Joseph Nodule on the umbilicus of a 53-year old female patient with ovarian cancer. A diagnostic workup was performed with a computerized tomography of abdominal cavity and pelvis showing an expansive cystic tumor formation with probable ovarian origin. Two separate histopathologic readings were done on the cutaneous lesion which revealed contradicting findings of benign versus malignant tumors. Immunohistochemical stains done showed that the lesion was positive for ERG and negative for epithelial differentiation markers. No surgical intervention was done at the time of consultation as a cutaneous metastasis was primarily considered initially. It is crucial to rule out a diagnosis of Sister Mary Joseph nodule, especially in a background of ovarian carcinoma as it may mimic vascular lesions occurring on the umbilicus. Immunohistochemical staining is a significant tool to precisely diagnose such lesions so that it is neither inadequately nor aggressively managed.

Introduction: Angiosarcoma is a rare head and neck sarcoma of vascular endothelial cell origin. We report a case of angiosar- coma in an elderly male, and the multidisciplinary approach employed in his treatment. Case report: A 79-year-old male presented with a 4-month history of a rapidly enlarging black, soft, immovable tumor surround- ed by bruise-like patches over the right temporoparietal scalp. There was associated pruritus and bleeding when scratched. Dermoscopy showed bluish black crusts over the tumor, and surrounding violaceous patches. Wedge biopsy revealed a dermis with irregular vascular spaces infiltrating dermis, lined by atypical endothelial cells. Immunohistochemistry of the atypical in- filtrative cells was positive for CD31. These findings were consistent with angiosarcoma. The patient underwent wide excision with a rotational flap and split thickness skin graft. Postoperatively, the patient was referred to Oncology for adjuvant radiation therapy. Conclusion Even with treatment, the prognosis of angiosarcoma remains poor due to its aggressive nature, with a 5-year sur- vival rate ranging from 10-54%. However, early detection of the disease may increase patient survival rates. This rare case shows the importance of maintaining a high level of suspicion for lesions that have an atypical presentation to prevent delays in man- agement and improve patient outcomes.
