TAILIEUCHUNG - Ebook Atlas of spleen pathology: Part 2

(BQ) Part 2 book "Atlas of spleen pathology" presents the following contents: Nonhematopoietic lesions including vascular, reactive and systemic conditions, infections. Invite you to consult. | Nonhematopoietic Lesions Including Vascular 5 Nonhematopoietic lesions of the spleen can be quite challenging. In this chapter cysts of the spleen are illustrated. These include cysts of both infectious and noninfectious etiologies. Hamartoma a benign lesion characterized by proliferation of benign splenic red pulp components is illustrated as well as myoid angioendothelioma a purported variant of splenic hamartoma. Also the difficult area of inflammatory pseudotumor IPT and related entities is discussed. The specific diagnosis includes true IPT IPT-like follicular dendritic cell tumor and inflammatory myofibroblastic tumor. Vascular tumors of the spleen have a broad range of histologic appearance and clinical behavior. A wide range is illustrated including SANT littoral cell angioma and angiosarcoma. Finally a broad array of tumors metastatic to the spleen is illustrated. .

Gross image of a spleen section with a thick-walled cyst. Note the surrounding parenchyma is unremarkable. The wall is thickened and fibrous. The nature of the lining is not apparent in this gross examination Fig. Cyst. The wall of this splenic cyst is coarsely trabecular. By gross examination it is unclear if there is an epithelial mesothelial or no lining pseudocyst . Image courtesy of R. Neiman Harpswell ME. Fig. Cyst. Gross image of a splenic cyst. The inner wall has coarse trabeculation but the wall is relatively smooth. Microscopic examination of the lining is useful to determine the type of splenic cyst. Image courtesy of D.
