Posttransplant Lymphoproliferative Disorders Presenting as an External Nasal Deformity: A Case Report.

Posttransplant lymphoproliferative disorder usually appears in lymphoid tissues that form Waldeyer's rings or cervical lymph nodes in the head and neck. The early involvement of other head and neck subpoints is considered rare. This case is the first report of PTLD presenting as an external nasal deformity. The symptoms and clinical manifestations of PTLD in otorhinolaryngology are usually diverse and nonspecific but are early symptoms in the clinical course of PTLD.
