Glomus tumors of the hand are benign vascular tumors, which develop at the expense of the neuro-myo-arterial glomus. They represent about 1% -5% of all hand tumors. Their diagnosis is frequently delayed by the absence of specific signs, its confirmation is based on anatomopathological examination. Their treatment is based on complete surgical excision and restitution of the nail apparatus, the only guarantees of a good evolution without recurrence. We report the case of a recurrence of a glomus tumor of the ring finger in a woman where the pains reappeared 6 months after the first intervention.

Chondroblastoma is a primary bone tumor in children, adolescents and young adults, which accounts for 1% of all bone tumors. Epiphyseal or epiphysometaphyseal localization, this lesion usually develops from secondary ossification centers close to the knee, shoulder and hip. Although chondroblastoma is a nonaggressive benign tumor, it can very rarely show a locally aggressive character or a malignant transformation or even metastases. We describe a histologically proven case of an aggressive, primary chondroblastoma of the tibia invading soft tissue in a 22-year-old girl.
