Abstract
RATIONALE
Cutaneous metastasis of testicular choriocarcinoma is exceptionally uncommon. To our knowledge, only 14 cases have been reported in the past 10 years in the pubmed. We have an uncommon case of testicular choriocarcinoma who has metastasized to the adjacent skin and organ systems.
PATIENT CONCERNS
An 18-year-old male was diagnosed with initial presentation of cutaneous mass at the left back. Followly,biopsy was performed under local anesthesia.Histopathological examination was consistent with the diagnosis of metastatic choriocarcinoma.
DIAGNOSES
The histopathological assessment of the biopsied tissue, in combination with elevated serum β-HCG levels and presentation of testicular mass, indicated primary testicular choriocarcinoma with cutaneous and systemic metastasis.
INTERVENTIONS
Subsequently radical orchiectomy was performed.
OUTCOMES
Despite the case completed one cycle of cisplatin-based regimen chemotherapy, he died of multiple organ dysfunction syndrome 2 months after surgery.
LESSONS
In this report, cutaneous metastasis with testicular choriocarcinoma is extremely rare. It is important to recognize that this unusual variant of testicular choriocarcinoma has the potential to behave aggressively and to metastasize.
