Soft tissue lymphoma

Monitoring neoplasms in standardized registries facilitates epidemiologic studies of risk factors for tumor development and predisposition. In an observational study, we determined incidence rates (IR) and malignant tumor incidence rate ratios (IRR) by age, sex, and breed in Swiss dogs using demographic data from the official Swiss dog registration database Amicus. The dataset analyzed included 54'986 tumors diagnosed by histology and cytology in four Swiss veterinary pathology laboratories between 2008 and 2020...

We present the case of a 57-year-old female who initially presented with a chief complaint of left-sided orbital headaches and associated left eyelid swelling. Initial imaging work-up with CT head/orbit revealed soft tissue enhancement of the left orbital roof, concerning for neoplastic process (primary lymphoma versus extracranial primary tumor versus metastatic tumor). Further imaging studies with CT chest/abdomen/pelvis revealed an anterior mediastinal mass, concerning for possible thymoma versus lymphoma...

BACKGROUND: One of the exceptionally rare forms of non-Hodgkin's lymphoma (NHL) is primary cardiac lymphoma (PCL). The principal clinical manifestation in patients with PCL involves cardiac symptoms resulting from myocardial infiltration by lymphoma, including arrhythmias, heart failure, and chest pain. 18 F-FDG PET/CT serves as a reliable and indispensable imaging modality for assessing clinically staging NHL. CASE REPORT: We present a rare case involving a 72-year-old woman diagnosed with primary intracardiac diffuse large B-cell lymphoma...

Extranodal natural killer T-cell lymphoma, nasal type (ENKTCL), is a rare form of non-Hodgkin lymphoma that is strongly related to Epstein-Barr Virus (EBV) infection and commonly presents as "midline lethal granuloma." Herein, we report a middle-aged lady who presented with a two-week history of fever, sore throat and constitutional symptoms. Intraoral examination revealed a lacerated soft palate with an ulcerated uvula. A diagnosis of ENKTCL was confirmed through deep biopsies under general anaesthesia supplemented with a positive serum EBV genome...

BACKGROUND: Firefighters are faced with a broad range of toxic exposures during their work, including known and suspected carcinogens. The current study is an update to the previously published meta-analysis of cancer risk among firefighters by Soteriades and colleagues, and focuses on studies published from 2008 to 2020. METHODS: A comprehensive search of the literature was conducted, including electronic databases and bibliographies of recently published papers...

A 56-year-old woman debuted with a palpable painless mass in the anterior thorax wall at the level of the second and third right parasternal intercostal space, which progressively increased in size over 5 months accompanied by localized skin rash, mild dyspnea and chest pain when changing position. Imaging studies showed a soft tissue mass measuring 75 × 62 mm and a density of 34 Hounsfield Units that had caused the lysis of the costal arches and grew expansively towards the anterior mediastinum, without identifying mediastinal adenopathies only by this imaging method...

PURPOSE: The primary objective of this investigation was to devise a mobile application for self-management of cancer-related discomfort, with the overarching goal of enhancing patients' overall well-being. Would the utilization of the self-management application result in an amelioration of life quality compared to conventional follow-up procedures? METHODS: Modules were meticulously devised with the collaborative expertise of oncology pain specialists employing the Delphi technique...

Mantle cell lymphoma (MCL) constitutes 3%-10% of non-Hodgkin lymphoma and is characterized by t (11:14)(q13;q32). The common presentation is generalized lymphadenopathy with weight loss, infrequently night sweats, and fever. Among histological subtypes of MCL, the blastoid variant of MCL constitutes 10%-15% of all the cases. It is challenging to diagnose the blastoid variant of MCL based on its morphology alone as it mimics large B-cell lymphoma. Hence, the immunophenotyping and molecular studies aid in its correct diagnosis...

Corynebacterium is generally considered a contaminant in clinical practice. However, it may cause bacteremia in patients with hematologic disorders, and factors that contribute to its mortality are unclear. A case series and systematic literature review identified 96 cases of Corynebacterium bacteremia inhematologic disorderpatients. The median age was 50.5 years (range: 2-93 years), with 79 (82%) patients 18 years or older, and 64 (67%) patients male. Most cases involved hematologic malignancies, and neutropenia was observed in approximately 75% cases...

Anaplastic large-cell lymphoma (ALCL) is a subtype of T-cell lymphoma. This disease mainly affects lymph nodes, although extranodal sites may also be involved. Lymphoma in the pancreas is a rare clinical entity whether it manifests as primary or extranodal involvement. We discuss an unusual case of a 29-year-old male patient who presented with epigastric pain and a right neck mass. The patient's symptoms, physical examination, and laboratory tests prompted further investigation using imaging modalities such as CT, MRI, and endoscopic ultrasound, which revealed the presence of soft tissue masses in the right supraclavicular region and an ill-defined lesion within the pancreatic head...

BACKGROUND: Interpretation of malignant soft tissue spinal canal tumors imaging is essential in guiding spine surgeons to establish a differential diagnosis. This task is intricate due to a great radiologic pattern overlap among entities. We present in this manuscript a step-by-step strategy that can guide spine surgeons identify a likely malignant soft tissue lesion in the spinal canal based on imaging features. In addition, we provide a review of the radiologic features of malignant soft tissue spinal canal tumors, assisting spine surgeons refining their diagnostic approach based on several essential imaging characteristics...

Plasmablastic lymphoma is a rare type of highly aggressive B-cell non-Hodgkin lymphoma that usually occurs in immunocompromised patients and involves chiefly extra-nodal sites such as the oral cavity, jaw, gastrointestinal tract, soft tissue, bone, and skin. People above the age of 50 years are more commonly affected, with male predominance having a survival rate of 8 to 15 months. Here, we describe the case of a 48-year-old man who had an isolated plasmablastic lymphoma of the right sphenoid bone without any immunodeficiency...

(1) Background: Diagnosis of glioblastoma (GBM), solitary brain metastases (SBM), and primary central nervous system lymphoma (PCNSL) plays a decisive role in the development of personalized treatment plans. Constructing a deep learning classification network to diagnose GBM, SBM, and PCNSL with multi-modal MRI is important and necessary. (2) Subjects: GBM, SBM, and PCNSL were confirmed by histopathology with the multi-modal MRI examination (study from 1225 subjects, average age 53 years, 671 males), 3.0 T T2 fluid-attenuated inversion recovery (T2-Flair), and Contrast-enhanced T1-weighted imaging (CE-T1WI)...

Plasmablastic transformation of follicular lymphoma is very rare and has been reported in only 5 cases till date. We report a case of simultaneous identification of extranodal, soft tissue plasmablastic lymphoma in the ankle and bone marrow involvement by follicular lymphoma. This unusual case presentation is a challenge for the treating physician with the patient becoming resistant to chemotherapy and succumbing to the disease within a few months of diagnosis. These cases are known to have an aggressive clinical course with very poor prognosis and survival rate of less than 6 months...

BACKGROUND AND AIMS: Angiosarcoma (AS) is a rare malignant vascular tumor that phenotypically and functionally recapitulate normal endothelium. They constitute approximately 2-4% of soft tissue sarcomas. We present 36 cases of head and neck AS diagnosed for 11 years at a tertiary care hospital in South India to analyze the clinical, pathological, and immunophenotypic profiles with special emphasis on their differential diagnoses and diagnostic pitfalls. MATERIALS AND METHODS: Head and neck AS diagnosed from January 2006 to December 2017 were included...

Central neuraxial blocks can be a vital therapeutic tool for neuropathic pain, but they are infrequently implemented for pain management in cancer patients. Upon a literature review, further data on the role or efficacy of central nerve blocks for neuropathic cancer pain would be beneficial. Additionally, evidence-based guidelines and practices are lacking regarding additional interventions for neuropathic pain relief, a common manifestation of cancer burden. Here, we report the case of a 29-year-old male patient who presented in the ED with intractable neuropathic pain from extensive diffuse large B-cell lymphoma...

INTRODUCTION: Follicular Dendritic Cell Sarcomas (FDCS)was first found in 1986; the specificity of the disease is its rarity, with an incidence of only 0.4%, numerous doctors for its lack of understanding, the accuracy of imaging diagnosis is not great, which is easy to delay the treatment. This article summarizes several characteristic imaging manifestations of FDCS to provide imaging physicians with an understanding of the imaging properties of this rare disease. When faced with complex cases, the radiologist can consider this disease and include it in the differential diagnosis...

STUDY QUESTION: Can we simultaneously assess risk for multiple cancers to identify familial multicancer patterns in families of azoospermic and severely oligozoospermic men? SUMMARY ANSWER: Distinct familial cancer patterns were observed in the azoospermia and severe oligozoospermia cohorts, suggesting heterogeneity in familial cancer risk by both type of subfertility and within subfertility type. WHAT IS KNOWN ALREADY: Subfertile men and their relatives show increased risk for certain cancers including testicular, thyroid, and pediatric...

BACKGROUND: Atrazine is a common agricultural herbicide in the United States. Few epidemiologic studies have evaluated cancer risks. Previous analyses within the Agricultural Health Study (AHS) have found some evidence of associations with cancer at some sites. OBJECTIVE: We updated exposure information, incident cases, and follow-up time to assess the associations between atrazine use and cancer at specific sites in the AHS. METHODS: Information about lifetime pesticide use was reported at enrollment (1993-1997) and follow-up (1999-2005)...

BACKGROUND: Primary bone lymphoma (PBL) is a rare form of extra nodal non-Hodgkin's lymphoma (NHL). CASE DESCRIPTION: We describe a 39-year-old-male with no medical history who presented with unilateral facial swelling following a tooth extraction. Initial diagnoses after various presentations over the course of three weeks, based on inflammatory and infectious aetiologies. However, the patient was ultimately diagnosed with diffuse large B-cell lymphoma. DISCUSSION: Symptoms of PBL are very similar to inflammatory and infectious diseases of the bone, such as osteomyelitis or osteonecrosis...
