SIMPLE OSSEOUS CYST OF THE CALCANEUS: A CASE REPORT.

Abstract

Bone tumors are pathologies resulting from modifications in the bone structure and its content, they can present as benign or malignant, primitive or metastatic tumor lesions, depending on various factors: age of presentation, location, growth rate, periosteal reaction and infiltration to neighboring structures. The publications show that small, asymptomatic and small bone cysts do not require treatment, up to 25% are spontaneous resolution after a pathological fracture; while larger cysts with thin bark require some type of intervention.The case of a 17-year-old female patient is presented, who presents for presenting moderate intensity pain in the left heel that intensifies on ambulation, with a time of 2 months of evolution, after a blunt trauma in this region. On physical examination, pain from the pressure digit and active-passive mobilization maneuvers were evidenced on the external lateral aspect at the calcaneus level of the left foot. A simple lateral radiograph of the left calcaneus was performed, showing a 3 by 3 cm circular lytic lesion involving the anteroinferior region of the calcaneus.In conclusion, simple or solitary bone cyst is a benign pathology that, although it does not endanger the person’s life, can seriously affect the functionality of the foot. Currently, there is no standardized treatment for the management of this pathology, current surgical techniques, especially curettage and bone autograft are very promising.
