Mantle cell lymphoma is one of the B-cell lymphomas. The concurrent presentation of mantle cell lymphoma with large granular lymphocytic leukemia simultaneously has never been reported. In this case we present an old man with concomitant mantle cell lymphoma and large granular lymphocytic leukemia diagnosed by the morphology of the bone marrow aspiration, immunophenotyping of the peripheral blo...

Gastrointestinal stromal tumor (GIST) and mantle cell lymphoma involving the appendix are rare as individual disease entities. Their coexistence has not been previously reported in the literature. We describe a 65-year old female who presented with extensive ileocecal mantle cell lymphoma, which extended to the appendix. The appendix was involved by mantle cell lymphoma and an incidental coexis...

stool for 2 months. He had been diagnosed as having mantle cell lymphoma of the spleen 8 years ago, and complete remission was achieved after chemotherapy. A computed tomography (CT) scan of the abdomen, taken to evaluate the intraabdominal lymph nodes, revealed a rectal mass with perilesional lymphadenopathy, A primary rectal cancer was suspected (●" Fig. 1, 2). Colonoscopy revealed an ulcerat...

Ocular adnexal lymphoma is the most frequent malignancy occurring in the eye region. With regard to the histology of these lesions, 2% to 7% of non-Hodgkin's lymphomas located in the periocular region are mantle cell lymphomas. A few cases of mantle cell lymphoma characterized by a fairly indolent course and prolonged survival have been described in the medical literature. We here report on a p...

INTRODUCTION Primary mantle cell lymphoma of the esophagus is quite rare, and we report here a case of a submucosal polypoid tumor of the esophagus that was pathologically similar, but not identical, to mantle cell lymphoma. CASE PRESENTATION A 66-year-old man underwent surgery in our hospital for a submucosal tumor of the esophagus. Histopathologically, the submucosal tumor uniformly showed ...

Clonal heterogeneity in lymphoid malignancies has been recently reported in adult T-cell lymphoma/leukemia, peripheral T-cell lymphoma, not otherwise specified, and mantle cell lymphoma. Our analysis was extended to other types of lymphoma including marginal zone lymphoma, follicular lymphoma and diffuse large B-cell lymphoma. To determine the presence of clonal heterogeneity, 332 cases were ex...

We present a case of a pleural space malignancy masked by an atypical presentation of mantle cell lymphoma. Our patient presented with a large pleural effusion and right sided pleural studding, initially attributed to a new diagnosis of mantle cell lymphoma. Rare atypical epithelial cells were also seen amongst the clonal population of lymphocytes. The patient lacked systemic manifestations of ...

Brain parenchymal involvement by mantle cell lymphoma is rare and confers a grim prognosis. More commonly, patients with central nervous system manifestations of mantle cell lymphoma have leptomeningeal involvement on radiographic studies with malignant cells found in the cerebrospinal fluid. Risk factors for central nervous system involvement include a high proliferation index, bone marrow inv...

Activation of the phosphatidylinositol 3-kinase/mechanistic target of rapamycin pathway plays a role in the pathogenesis of non-Hodgkin lymphoma. This multicenter, open-label phase 2 study evaluated buparlisib (BKM120), a pan-class I phosphatidylinositol 3-kinase inhibitor, in patients with relapsed or refractory non-Hodgkin lymphoma. Three separate cohorts of patients (with diffuse large B-cel...
