Superficial CD34-positive fibroblastic tumor (SCPFT) is a recently described entity that, despite significant pleomorphism, carries a good prognosis. We briefly describe this tumor and its principal differential diagnoses. Recognition of SCPFTs, including the clinical context in which they arise, is important to avoid confusion with other pleomorphic soft tissue tumors, particularly neoplasms in the group of pleomorphic sarcomas, which are typically aggressive tumors that could lead to unnecessary overtreatment.
Papillary endothelial hyperplasia or Masson tumor most commonly occurs within the extremities and head and neck. It is usually of intravascular type, associated with thrombus formation and organization within a preexisting vessel or vascular malformation, but rarely can be extravascular. We describe the first 2 cases of this extravascular type to occur within the ovary, one of which mimicked malignancy radiologically. This condition is thought to represent a reactive phenomenon with reparative response secondary to thrombosis although with an unclear underlying pathogenesis. The prognosis is generally good, with complete surgical resection usually representing adequate treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
