Extranodal NK/T-cell lymphoma nasal type mimicking pyoderma gangrenosum.
The new World Health Organization / European Organization for Research and Treatment of Cancer (WHO-EORTC) consensus classification for cutaneous lympho-mas recognizes two main groups of CD56 + lymphomas: extranodal natural killer (NK)/T-cell lymphoma nasal type, and CD56+ haematodermic neoplasm (formerly known as blastic NK cell lymphoma (1). NK/T-cell lymphoma nasal type is the most common ly...
متن کاملExtranodal Natural Killer/T-cell lymphoma, nasal type: ‘midline lethal granuloma.’ A case report
Extranodal natural killer/T cell lymphoma, nasal type, is a non-Hodgkin lymphoma, most commonly affecting the nasal cavity, paranasal sinuses and nasopharynx. Clinically it is characterised by destruction of facial tissues, commencing in the midline. In most cases it arises from malignant transformation of natural killer cells (NK); sometimes from malignant transformation of cytotoxic T cells.E...
متن کاملCentral giant cell granuloma mimicking an adenomatoid odontogenic tumor
Central giant cell granulomas are non-neoplastic lesions of unknown etiology. They affect females more than males with the mandibular anterior region being the most common site of occurrence. Clinically central giant cell granulomas present as asymptomatic, expansile swellings causing deviation of associated teeth. Radiologically they usually presents as multilocular lesions causing expansion o...
متن کاملNKT Cell Responses to B Cell Lymphoma
Natural killer T (NKT) cells are a unique subset of CD1d-restricted T lymphocytes that express characteristics of both T cells and natural killer cells. NKT cells mediate tumor immune-surveillance; however, NKT cells are numerically reduced and functionally impaired in lymphoma patients. Many hematologic malignancies express CD1d molecules and co-stimulatory proteins needed to induce anti-tumor...
متن کاملDisseminated Mycobacterium marinum Infection With a Destructive Nasal Lesion Mimicking Extranodal NK/T Cell Lymphoma
Mycobacterium marinum is a ubiquitous waterborne organism that mainly causes skin infection in immunocompetent patients, and its disseminated infection is rare. Extranodal NK/T cell lymphoma, nasal type (ENKL) usually localizes at the nasal and/or paranasal area, but occasionally disseminates into the skin/soft tissue and gastrointestinal tract. Compromised immunity is a risk factor for develop...
