“…Although the etiology of the condition is still uncertain, multifactorial events appear to be associated. Secondary factors—for example, local trauma and previous vascular disorders—account for approximately 30% of the cases, but the triggering stimulus cannot be identified in 70% of them 25 . Some theories suggest that the excessive endothelial proliferation stimulated by the local production of growth factors could explain the causative factor of IPEH 20,26 .…”

Background Intravascular papillary endothelial hyperplasia is an unusual vascular lesion characterized by the proliferation of endothelial cells. The aim of this study was to determine the frequency and general features of this lesion. Methods Biopsy records of three oral pathology services were reviewed for intravascular papillary endothelial hyperplasia cases from 1959 to 2020. In addition, a systematic review of case reports and case series was carried out in eight electronic databases. Results Of the 65 205 retrieved cases, 20 (0.03%) were diagnosed as intravascular papillary endothelial hyperplasia. Mean patient age was 46.55 years, and females (12 cases/60%) were more affected. The lower lip (9 cases/47.36%) was the most commonly affected site, and the lesions were generally asymptomatic (7 cases/63.63%). Clinically, 90% of the lesions presented (18 cases) as a nodule, with a mean size of 1.13 cm. The clinical diagnostic hypotheses most frequently raised were mucocele (6 cases/37.50%) and hemangioma (5 cases/31.25%). An excisional biopsy was chosen in all cases for treatment. Forty‐nine studies of the systematic review were included, yielding 105 cases. The literature showed similarity in all variables. Conclusion Despite the uncommon frequency, clinicians and oral pathologists should familiarize themselves with the similarities between intravascular papillary endothelial hyperplasia and some other lesions in terms of clinical and histological features.

Masson's tumor, also known as intravascular papillary endothelial hyperplasia (IPEH), is a rare and benign vascular disease in which there is a reactive hyperplasia of intravascular endothelial cells. This tumor is most commonly found in soft tissues in the head, neck and upper extremities. We report a rare case of IPEH on the vulva. A Hispanic woman in her mid-thirties presented with a painful and pruritic left vulvar mass. On physical examination, a pedunculated mass was visualized on the left labia majora. Under pathologic examination, it was concluded the lesion was IPEH and it was surgically excised. This is a rare case of IPEH located on the vulva. However, despite this rarity, a simple local excision could be used to manage IPEH.

“…Its aetiology is generally considered as multifactorial even though in 30% of cases it arises after a local trauma or it is associated with vascular conditions (hemangiomas, vascular malformations). 4 Radiological diagnosis of MT is usually challenging, due to the infrequent occurrence in head and neck and the similarity with vascular tumors like low grade angiosarcoma or Kaposi's sarcoma.…”

Background: Masson's tumor (MT) is a rare benign vascular disease. In literature, detailed description of its radiological findings is not available and functional imaging such as diffusion weighted (DW)-MRI has never been described. We aim to summarize the CT and MRI findings in our representative case and to conduct a systematic review of the literature. Case Presentation: We reported a 54-year-old ex-smoker male patient who presented with a nodular mass to the left cheek. He denied any previous trauma. CT examination performed on initial presentation revealed a well circumscribed solid oval mass with soft tissue density, a calcified focus and no significative contrast enhancement after contrast administration. MRI showed a well circumscribed solid oval mass, with intermediate T2 signal intensity with areas of high T2 signal intensity and the presence of peripheral high-flow serpentine vessels, low T1 signal intensity. The mass showed a non-enhancing area with enhancing vessels after intravenous contrast administration. We surveyed CT and MRI findings of head and neck MT of English and French language papers, published from 1981 to 2019, together with our representative case. We included articles with a description of CT and/or MRI findings of head and neck MT. Conclusion:We have experienced one case and have evaluated imaging findings through systematic review. Only 36 articles were eligible. CT and MRI findings were reported in 27 and 23 articles, respectively. To date, no diffusion weighted imaging (DWI)-MRI findings have been described. The most frequent findings in CT were a well-defined mass with high or soft tissue density. The most frequent MRI findings were a non-homogeneous signal intensity in T1 and T2 weighted sequences, with foci of hyperintensity, multiple septations or flow voids. After contrast administration, the enhancement could be homogeneous, non-homogeneous, nodular or peripheral. In our case, we found a non-homogeneous hyperintensity in DWI-MRI with an area of restricted diffusion and low apparent diffusion coefficient (ADC) was observed (0.963 × 10 −3 mm 2 /s +\-0.12 SD). The imaging characteristics cannot provide a pre-operative identikit of MT and surgical removal is necessary to accurately differentiate it from malignant angiosarcoma but radiological evaluation is useful in surgical planning.
