Abstract

Intravascular papillary endothelial hyperplasia (Masson's hemangioma) is a disease characterized by exuberant endothelial proliferation within the lumen of medium-sized veins. In 1923, Masson regarded this disease as a neoplasm inducing endothelial proliferation, however, now it is considered to be a reactive vascular proliferation following traumatic vascular stasis. The lesion has a propensity to occur in the head, neck, fingers, and trunk. Occurrence within the abdominal cavity is known to be very rare, and especially in the liver, there has been no reported case up to date. The authors have experienced intravascular papillary endothelial hyperplasia of the liver in a 69-yr-old woman, and report the case with a review of the literature.

Intravascular papillary endothelial hyperplasia. A clinicopathologic study of 91 cases.

Y Daimaru, H. Yokota-Hashimoto, M Enjoji (1983)

Ninety-one cases of intravascular papillary endothelial hyperplasia were studied clinically and histologically. This peculiar benign process, occasionally resembling hemangiosarcoma, was subgrouped in the following categories: a pure form that occurs within a dilated vascular space (30 cases), a mixed form that appears as a focal change in a hemangioma (55 cases), a third form (six cases) that belongs to neither of the first two. In the pure form, the lesions were most frequently situated in the subcutis of fingers (14 cases), of the head and neck (seven cases), and in the region between the elbows and hands (six cases). In the mixed form, half of the accompanying hemangiomas were intramuscular in no particular predilective sites. Papillary proliferation of endothelial cells was commonly found to be closely associated with thrombotic material and seemed to be an unusual feature of a thrombus undergoing organization.

Intravascular papillary endothelial hyperplasia.

Katherine M Enzinger, P. A. Clearkin (1976)

Papillary endothelial hyperplasia is a peculiar benign intravascular process that bears a remarkable resemblance to a hemangiosarcoma. In 44 cases of this lesion studied from the files of the Armed Forces Institute of Pathology, the process manifested as a small tumor-like lesion that occurred most frequently in the subcutis of the fingers (14 cases), the head and neck region (ten), and the trunk (seven). Microscopically, the tuft-like or papillary proliferation of endothelial cells was nearly always intimately associated with a thrombus and seemed to represent a peculiar variant of an organizing process. Features that aided in recognition and differential diagnosis from a hemangio-sarcoma included the intraluminal location of the lesion, the absence of tissue necrosis, and the intimate association of the proliferated tuft-like structures with thrombotic material. Follow-up information obtained in 31 cases indicated a benign clinical course despite the sarcoma-like microscopic appearance of this condition.

Masson's "vegetant intravascular hemangioendothelioma:" a lesion often mistaken for angiosarcoma: study of seventeen cases located in the skin and soft tissues.

J Rosai, Chay Kuo, Brian C Sayers (1976)

The occurrence of Masson's "hemangio-endotheliome vegetant intravasculaire" (Masson's pseudoangiosarcoma) in the skin and soft tissues is illustrated with 17 surgically excised specimens. Two forms are recognized; it may appear either as a pure lesion or as a focal condition in a pre-existing vascular process, such as pyogenic granuloma or hemangioma. The clinical appearance is not specific and the diagnosis can only be established by microscopic examination. It shows a predilection for the head and extremities. Its characteristic morphologic appearance makes possible its differentiation from a group of benign and malignant vascular proliferations. The key microscopic feature is the presence of a papillary growth composed of hyperplastic endothelial cells supported by delicate fibrous stalks entirely confined within the vascular lumen. The lesion should not be mistaken for angiosarcoma, since its clinical behavior is invariably benign.
