The cytologic features of splenic hamartoma and of littoral cell angioma of the spleen were described three times in cytologic literature: two were bench\u2010top aspirates and one was FNA biopsy thought to be metastatic carcinoma. To the best of our knowledge, the current two cases were the first diagnosed by FNA biopsy. Our approach to the FNA biopsy diagnosis of these rare vascular neoplasms via compact cell block and immunohistochemistry is described. The differential diagnosis with other primary vascular splenic neoplasms is also discussed. Diagn.
