We present a case of an unusual retinal infiltrate requiring retinal biopsy for definitive diagnosis. A 62-year-old man with treated lymphoma presented with decreased vision in the right eye associated with a white retinal lesion, which extended inferonasally from an edematous disc. Intraocular lymphoma was considered as a diagnosis; thus, the patient was managed with vitrectomy and retinal bio...

Introduction: Central mucoepidermoid carcinoma (CMEC) is a rare primary intraosseous bony lesion. The mandible is more commonly affected than the maxilla. CMEC is frequently misdiagnosed radiographically and clinically as a benign odontogenic tumor or cyst. Case Presentation: We present a rare case with a secondary malignant neoplasm. A male patient was initially diagnosed with B-cell non-Hodg...

Chylous pleural effusion is characterized by milky-appearing fluid with elevated triglyceride content and presence of chylomicrons in the pleural space. Even though patients with lymphoma sometimes present with malignant pleural effusion, chylous effusion is rarely encountered as a presenting feature in such patients. We present a 47-year-old woman diagnosed as follicular lymphoma who presented...

Distinguishing between thyroid malignant lymphoma and lymphocytic thyroiditis (Hashimoto's thyroiditis) is quite difficult and problematic. Molecular techniques to detect clonal lymphoid proliferation based on Ig heavy chain (IgH) gene rearrangement may be used to facilitate more accurate diagnosis of malignant lymphoma. We recently established a method for diagnosing thyroid tumors by analyzin...

PURPOSE To follow the changes in the electroretinograms (ERGs) in a patient with primary intraocular lymphoma (PIOL) who had a complete remission after chemotherapy. METHODS ERGs were recorded in a 41-year-old woman with PIOL during and after complete remission with chemotherapy. The patient was diagnosed with PIOL from both the ocular signs and the medical history of cranial lymphoma. RESU...

Malignant lymphomas may originate from any area of the body and cause a variety of symptoms. However, a malignant lymphoma causing urinary symptoms is uncommon. We report a unique case of a 77-year-old woman who presented with a persistent pollakiuria. Radiographic imaging showed a large pelvic mass (13 × 13 × 11 cm) remarkably compressing and invading the bladder wall and accompanied with bila...

This case report describes a low-grade malignant B-cell lymphoma (lymphocytic lymphoma) in 14-year-old mixed breed cat, diagnosed by bronchoscopy and diagnostic imaging (radiography, ultrasound computed tomography). The patient was treated with surgery, postoperative complications included blindness severe mycoplasma infection of the thoracic cavity, which using vacuum-assisted closure device. ...

BACKGROUND Few cases of malignant tumors arising in a blind painful eye have previously been described. We described two cases of a blind painful eye containing an unsuspected tumor, which were enucleated to relieve the pain. CASE PRESENTATIONS Case 1: A 57 year-old Caucasian man presented with recurrent orbital cellulitis and endophthalmitis in the left eye (OS). The OS was blind and painful...

BACKGROUND Recently, brentuximab vedotin has become a promising therapeutic approach for CD30-positive hematological malignancies, but its role in other relapsed or refractory malignant lymphoma needs to be proven. Brentuximab vedotin was demonstrated effective, but no study has summarized the concrete effect of brentuximab vedotin in malignant lymphoma. To truly know the role of brentuximab ve...

INTRODUCTION Primary splenic malignant lymphoma is quite a rare disease, and its preoperative diagnosis is difficult. CASE PRESENTATION An 80-year-old man was diagnosed with advanced rectosigmoid cancer with liver and splenic metastases, for which he underwent single-incision laparoscopic high anterior resection for the primary rectosigmoid cancer. After chemotherapy, he underwent laparoscopy...
