Pure choriocarcinoma of testis with rare gingival and skin metastases.

A 22-year-old man presented with complaints of gingival and skin lesions. Physical examination revealed the presence of two nodular lesions, one over the sternum, 3 cm in size, and another, on the right side of chin, 1 cm in size. There was another fleshy soft tissue deposit over the left lower gingiva, in the oral cavity. He had noticed these lesions ten days prior to his visit to the hospital. In addition, there was left testicular non-tender swelling which had been present for two months, but was not investigated. Fine-needle aspiration cytology from skin and gingival lesions was suggestive of metastatic deposits. Patient underwent left high orchidectomy, and histopathological examination was consistent with the diagnosis of pure choriocarcinoma. Although rare, cases of testicular neoplasms and especially choriocarcinoma of the testis leading to skin metastases have been reported, but case reports of choriocarcinoma of testis metastatic to gingiva have been reported exceptionally in the English literature. We report this unique case of a young man with pure choricarcinoma of testis with unusual gingival and skin metastases.
