【 摘 要 】

Eccrine poroma is a rare benign neoplasm of the eccrine sweat gland that usually presents as a small skin lesion such as a papule or nodule. This benign tumor has an overall good prognosis; however, eccrine porocarcinomas can arise from long-standing pre-existing benign eccrine poromas. We reported the case of a 37-year-old man with mental retardation who presented with an 8-cm pedunculated and densely pigmented eccrine poroma on the left hip. The tumor showed low signal intensity on T1-weighted MRI, with inhomogenously high signal intensity on T2-weighted images and strong contrast enhancement after intravenous gadolinium administration. It directly extended from the dermal layer, and the subcutaneous tissue was preserved. Radiologists should be aware that eccrine poromas could be large and pedunculated. Furthermore, related MRI findings and diagnostic clues should be carefully considered.
