PENILE METASTASIS FROM A EXTRANODAL T CELL LYMPHOMA: A CASE REPORT AND REVIEW OF THE LITERATURE
Dr. Shivalingaiah M.* and Dr. Pramod Adiga
ABSTRACT
Extranodal NK/T-cell lymphoma (NKTL) is a highly aggressive neoplasm that commonly involves the nasal cavity, which accounts for 1-10% of all non-Hodgkin's lymphoma1,2. The estimated 5-year overall survival rate is 40-50%. This type of tumor has distinct clinicopathological features and no standard treatment options. In the early stages, the disease often presents as a destructive lesion within the centrofacial region. However, in advanced cases, the disease may involve distant extranodal organs, frequently including the skin, liver, lung, testis or central nervous system. Penile involvement, whether primary or secondary, is extremely rare and seldom reported in the
literature. Early diagnosis of lymphoma can aid in avoidance unnecessary penile amputation and allow for optimal management. The first English-language case report of extranodal NKTL with involvement of the penis was reported in 2008, and is the only study in English to describe this entity.[3]
