Late breast implant seroma may be the presentation of a breast implant-associated anaplastic large cell lymphoma (BI-ALCL), which claims for a prompt recognition. However, BI-ALCL diagnosis on fine-needle aspiration (FNA) might be challenging for pathologists lacking experience with peri-implant breast effusions. Sixty-seven late breast implant seromas collected by FNA from 50 patients were eva...
BACKGROUND Primary pancreatic lymphoma is a rare tumour of the pancreas. Data on the role of endoscopic ultrasound guided fine needle aspiration for its diagnosis are scant. AIM To identify the frequency of occurrence, sonographic characteristics and cytological findings that are predictive of primary pancreatic lymphoma. METHODS Pancreatic lymphoma cases were identified by retrospective re...
Epstein-Barr virus (EBV) associated lymphoproliferative disorder (LPD) after immunosuppressive therapy for aplastic anemia (AA) is extremely rare in a nontransplant setting and has not been well described. This report describes a severe AA patient in whom fatal EBV-LPD developed after being treated with rabbit antithymocyte globulins (ATG) and cyclosporine A (CsA). An 81-year-old man was diagno...
Pregnancy triggers immunological changes aimed to tolerate the fetus, but its impact on B lymphocytes is poorly understood. In addition, exposure to the Plasmodium parasite is associated with altered distribution of peripheral memory B cell (MBC) subsets. To study the combined impact of high malaria exposure and pregnancy in B cell subpopulations, we analyzed PBMCs from pregnant and nonpregnant...
The Prevalence and Importance of Variant Patterns in Nodular Lymphocyte Predominant Hodgkin Lymphoma
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a rare type of B-cell lymphoma with good prognosis and distinct clinicopathologic features. The hallmark histological feature is the presence of malignant lymphocyte predominant (LP) cells embedded within nodules predominantly composed of small B-lymphocytes. Immunoarchitectural variations from these classic nodules could occur. The cli...
An inflammatory liposarcoma is a rare variant of a well-differentiated liposarcoma. A case of a giant variety of an inflammatory well-differentiated liposarcoma is being reported. CT scan revealed a large abdomino-pelvic mass which had displaced the gut loops to left and posteriorly and urinary bladder and uterus to right. FNAC yielded mature adipocytes with no evidence of atypical cells. The l...
An 8-year-old female Golden Retriever had an oral mass and lameness. Multiple osteolysis of the systemic skeleton without monoclonal gammopathy was shown on electrophoresis of serum and urine samples. Cytological and histopathological examinations of the oral mass revealed atypical polymorphic cells similar to myeloid cells, and bone marrow aspiration indicated that these abnormal cells also mi...
hydatid cyst is a zoonotic disease that is common in the mediterranean region. thoracic wall, rib or extrapulmonary intrathoracic localization of the cysts is very rare. giant extrapulmonary intrathoracic hydatid cysts can lead to both diagnostic and treatment difficulties and can be confused with tumor. we present a case of a hydatid cyst with thoracic wall involvement mimicking tumor. we conf...
ETHAL MIDLINE granuloma and lymphomatoid L granulomatosis are related angiocentric, angiodestructive lymphoproliferative disorders that involve the upper and lower respiratory tracts, respectively. They are both characterized by a heterogeneous infiltrate composed of small lymphocytes, mononuclear phagocytes, plasma cells, occasional eosinophils, and variable numbers of large, atypical lymphoid...
