Chondroid syringoma, also known as a cutaneous mixed tumor, is a rare benign neoplasm originating from the sweat glands, composed of epithelial structures immersed in a myxochondroid stroma. It usually presents as a solid, single tumor located on the face or neck with a chronic and asymptomatic course. We report the case of a 75-year-old woman with a slightly elevated lesion on the forehead, whose diagnosis was defined by histopathological analysis.

Eccrine syringofibroadenoma (EFAS) is a rare benign tumor that originates from the eccrine sweat glands. It has a predilection for the extremities of elderly individuals and may arise in association with various acquired or hereditary diseases and neoplastic skin disorders. We report the case of a 48-year-old man who had been quadriplegic due to transverse myelitis for 30 years, with a rapidly progressive plantar tumor that was difficult to diagnose.
