BACKGROUND
Primary splenic vascular lesions include the tumor and the inflammatory condition. A primary splenic vascular tumor is rare but is the most common tumor of the benign primary splenic tumors.
METHODS
We describe the clinicopathological, radiological, and immunophenotypical findings of 40 cases of primary vascular lesions identified at our hospital from 1996 to 2009.
RESULTS
The patients included 18 men and 22 women, aged 12 to 74 years, with a mean of 43.3-years and median of 40-years. They comprised 14 hemangiomas (35%), 13 lymphangiomas (32.5%), three hamartomas (7.5%), three littoral cell angiomas (7.5%), three sclerosing angiomatoid nodular transformations (SANT, 7.5%) and four angiosarcomas (10%). The majority of the patients (65%) were asymptomatic. Some of the patients (32.5%) complained of abdominal pain, and 2.5% of the patients presented with fever. Metastases were identified in 75% of the patients with an angiosarcoma at the initial work-up. One angiosarcoma patient died of the disease despite adjuvant chemoradiotherapy. The radiological findings for hamartoma, littoral cell angioma, and SANT were nonspecific. Microscopically, six types of vascular lesions showed classic morphological and immunophenotypical features of their type.
CONCLUSIONS
One should be aware of rare splenic vascular lesions when radiological findings are nonspecific. Histomorphological and immunophenotypical features are helpful for the differential diagnosis.

Abstract PDF

Herein we describe two cases of nasal glomus tumor. Histological findings were typical, save for one which was quite large (3.1 cm in its greatest dimension) with an invasive growth pattern and increased ki-67 labeling index (up to 10%). These features raised a red flag of similarity to a recently described "invasive glomus tumor of nasal cavity", suggesting a more aggressive form of glomus tumor. However, objective criteria for this possibility is lacking at present and more similar case studies are needed to establish a truly aggressive form of glomus tumor.
