Extranodal NK/T-cell lymphoma, nasal type, with extranasal presentation - a case report and a review of the literature.
Abstract
Extranodal NK/T-cell lymphoma (ENKTCL), nasal type is a very rare and aggressive non-Hodgkin lymphoma. Most commonly it occurs in the upper aerodigestive tract. But, it can also manifest at locations such as the skin, soft tissue, gastrointestinal tract (GI), lungs, testis, etc. These locations are designated as extranasal ENKTCL. The patients with the latter have often more adverse clinical features and poorer survival rate compared with nasal sites. We present a case of an 83-year-old patient with a primary ENKTCL, nasal type, with extranasal presentation in the right upper eyelid. Materials for the literature review was obtained by a comprehensive search on PubMed, which yielded 82 eligible cases with extranasal ENKTCL. Sixty-eight cases (83 %) were localized as primary ENKTCL in the lungs (17), central nervous system (CNS) (14), testis (11), GI-tract (7), skin (6), orbit and intraocular tissue (4), pancreas (2), adrenal gland (2), breast (1), etc. 14 cases (17 %) presented as extended or disseminated diseases involving exclusively organs outside the upper aerodigestive tract. There was no systematic pattern of organ involvement in the extended/disseminated ENKTCL. 63 % of the patient with localized extranasal ENKTCL and abo...Continue Reading
