Multiple primitive intracranial tumors with different histological characteristics are uncommon. Although coexistence of a medulloblastoma with glial tumors has been reported in children, medulloblastoma is rarely found in adults, especially those older than 40 years of age. We present an extremely rare case of a medulloblastoma developing in a 40-year-old male undergoing maintenance chemothera...
Gastric CD30-positive anaplastic large-cell lymphoma is a very rare disease. It is sometimes difficult to distinguish it from undifferentiated carcinoma, sarcoma and so on. We report here on a case of primary gastric anaplastic large-cell lymphoma. A 50-yr-old woman complained of epigastric pain and severe chest pain for 1 week. The gastroendoscopic examination revealed geographic mucosal irreg...
INTRODUCTION Anaplastic carcinoma of the thyroid is a rare but aggressive malignancy which can present with a rapidly enlarging neck mass or compressive sequelae of cough, dyspnoea, dysphagia and hoarseness. Treatment of such tumours is commonly palliative however they occasionally represent surgical challenges due to their rapid growth, diagnostic difficulty and locoregional spread. PRESENTA...
Anaplastic large cell lymphoma (ALCL) is a T cell lymphoma occurring commonly in childhood and rarely in adults. Central nervous system involvement in ALCL is very rare and cerebellar involvement at presentation has never been described. We examine the case of a young adult who presented with a cerebellar mass. A 19-year-old boy presented with signs of raised intracranial tension, which, on ima...
ALCL: anaplastic large cell lymphoma CL: composite lymphoma EBV: Epstein-Barr virus MF: mycosis fungoides INTRODUCTION Patients with mycosis fungoides (MF) are at increased risk of a second malignant neoplasm, especially lymphoma. We report a sexagenarian with a 14-year history of patch MF, stage IB, who had intravascular cutaneous anaplastic large cell lymphoma (ALCL) and cutaneous composite l...
Lymphomatoid papulosis (LyP) is a chronic self-healing skin eruption that is clinically benign but histologically mimics a malignant lymphoma. However, lymphomatoid papulosis with anaplastic large cell lymphoma responds poorly to medical treatments, including chemotherapies. We experienced a 60-year-old male patient with lymphomatoid papulosis occurred simultaneously with relapsed Ki-1-positive...
Anaplastic large cell lymphoma expressing anaplastic lymphoma kinase (ALK+ ALCL) is a distinct subtype of non-Hodgkin lymphoma. In this review, we discuss the historical findings that led to its classification as a unique disease, despite its varied clinical presentation and histology. We discuss the molecular mechanisms underlying ALK+ ALCL pathology and the questions that remain in the field....
An immunocompetent 29-year-old male presented with an embolic stroke from an unusual primary cardiac lymphoma. The cardiac lesion consisted of a polypoid, left atrial, mural fibrin thrombus with anaplastic tumor cells lining the surface of the clot. Histologic, immunophenotypic, and molecular characterizations were consistent with a diagnosis of CD30+ large B-cell lymphoma with anaplastic cytol...
