Trichoblastic carcinoma is an uncommon malignant neoplasm arising from follicular germinative cells. The high-grade trichoblastic carcinoma has been reported with lymphatic and hematogenous dissemination. The authors present a 59-year-old man with gluteal cleft trichoblastic carcinoma and highlight the useful role of serial 18F-FDG PET/CT examinations in the demonstration of initial and subsequent nodal metastasis in the inguina and pelvis.
