Littoral cell angiomas (LCAs) are rare splenic vascular neoplasms that arise from the cells lining the red pulp sinuses. The clinical course is benign and in most cases asymptomatic. However, as has been described in the literature, we have seen an association with malignant neoplasms and haematological disorders. The definitive diagnosis is made on histology and confirmed with immunohistochemistry. The use of percutaneous fine-needle aspiration biopsy (FNA) in preoperative diagnosis is controversial.

“…Usually the diagnosis is made after splenectomy for some other reason. However, around 45% of patients will present with splenomegaly, fever and features of hypersplenism (anaemia, thrombocytopenia) [2][3][4]. In our series, two of the patients were asymptomatic and only one of them had symptoms of hypersplenism.…”

“…24 Immunophenotypically, the lining cells of splenic lymphangioma express CD31, CD34, and focal positivity for CD68. 24 Splenic hamartoma and littoral cell hemangioma 12,25 are two other rare entities that can pose considerable diagnostic problems. Both entities can present as multiple nodules in the spleen, 22,25 therefore mimicking metastatic disease.…”

Fine needle aspiration (FNA) of the spleen is rarely performed, due to fear of procedure complications. The objective of this study is to review the cytologic diagnoses of aspiration biopsy of the spleen performed in a cancer center. Archival material (9-year period) was reviewed and correlated with histologic and ancillary test results, when available.Forty-one splenic FNA specimens were identified. There were no reported procedure complications. Nineteen cases were diagnosed as malignant. Of these, 11 were lymphomas. Nineteen cases were diagnosed as benign. There was one false-negative case and four false-positive cases. Primary splenic neoplasms were rare and misinterpreted as malignant. It is important to be familiar with the normal cytology of this uncommonly aspirated organ in order to successfully identify neoplastic and malignant processes. The use of ancillary studies is important in the definitive classification of benign and malignant splenic lesions.

“…[12345678] LCA is a benign tumor composed of anastomosing vascular channels with papillary projections and cyst-like spaces lined by tall endothelial cells oftentimes showing hemophagocytosis. [123] Although diagnosis of LCA is confirmed by morphology and immunohistochemistry, fine needle aspiration of tumor can help limit the differential diagnosis before operation. [3] To our knowledge, there have been few reports with cytological description of LCA in the literature.…”

Littoral cell angioma of the spleen: Cytological findings and review of the literature

Littoral cell angioma (LCA) is a unique lesion of the spleen that arises from the cells lining the venous sinuses of the splenic red pulp and shows the features of combined endothelial and histiocytic differentiation. Several cases of LCA have been reported in the literature; however, the cytological findings have been described for only a few cases. We report the case of an 11-year-old boy with anemia, epigastric abdominal pain, and splenomegaly. The splenic lesions showed anastomosing vascular channels with cyst-like spaces filled by many sloughed endothelial cells, which were positive for CD68 and CD31 and negative for CD34. Scraping cytology revealed isolated and clusters of three-dimensional bland looking, epithelioid foamy tumoral cells with low nuclear cytoplasmic ratio, which mostly contained intracytoplasmic hemosiderin pigment. Although the fine needle aspiration cytology of splenic lesions is uncommon and LCA is a rare splenic lesion, it must be noted in the differential diagnosis of any splenic vascular neoplasm.
