Testicular mixed germ cell tumour with isolated skip metastasis to unilateral pleura: First case reported in the literature

摘要

Introduction Testicular germ cell tumours metastasize in a very predictable fashion involving the retroperitoneal lymph nodes first followed by either lymphatic spread via thoracic duct or hematogenous spread to distant organs like lungs, liver and brain. Presentation of case We encountered a case of 21-year-old gentleman with mixed germ cell tumour of testis who later presented with respiratory complaints which turned out to be a metastatic differentiated teratoma of unilateral pleura without involvement of retroperitoneal lymph nodes or any other organs. Discussion Skip Metastasis to unilateral pleura is an extremely rare entity for testicular mixed germ cell tumour and no case has been reported in the literature so far.
