Stress Fracture of the Proximal Phalanx of the Great Toe

Three cases of stress fracture of the proximal phalanx of the great toe occurring in a 12-year-old female volleyball player, a 17-year-old female long distance runner, and a 12-year-old male soccer player are reported. This condition probably develops after repeated forced dorsiflexion of the first metatarsophalangeal joint with changing steps. When athletes who repeatedly run and jump complain of pain in the first metatarsophalangeal joint, and there is no history of trauma, this condition should also be considered.

Infiltrating lipoma - A clinical study of 10 cases.

Infiltrating lipoma is characteristic in its infiltrative growth pattern and its frequency of local recurrence in spite of the benignancy. It involves the intermuscular and intramuscular types.We evaluated 10 cases with infiltrating lipoma. Five cases were intermuscular and the other 5 were intramuscular type. The age of patients ranged from 1 to 69 years old (mean age: 47.7 years old). The majority of the tumor was sited in the extremities, especially in the upper extremities. No recurrence was seen in all cases. The utility in imaging techniques such as CT or MRI was remarkable for the clarification of localization and even diagnosis of this tumor.Wide resection must be recommended to prevent the local recurrence, especially in the intramuscular type.
