  The pacient may present local pain, the appearance of local deformation due to a tumor mass or occurrence of pathological fractures. [ncbi.nlm.nih.gov]

  To help differentiate bone pain from joint pain, the joint can be injected, usually with a long-lasting anesthetic (eg, bupivacaine ); if pain persists, it may be caused by the bone lesion. [merckmanuals.com]

• Swelling

  In addition, 21 years old male patient came with a complaint of swelling with mild, continuous pain in the lower left jaw region. [ncbi.nlm.nih.gov]

  Most common to children and adolescents, these spinal tumors cause pain and swelling, and can be large and vascular (numerous blood vessels). [cedars-sinai.edu]

  Both types can cause pain and swelling and, in rare cases, fractures in the involved bone. Aneurysmal bone cysts do not generally go away on their own. [childrenshospital.org]

  See a GP if you get a lump, pain or swelling in the bone after treatment This could mean the cyst has come back or you've developed an infection from surgery. [nhs.uk]

• Surgical Procedure

  ABC was localised in the posterior right region of the mandible in an 11-year-old boy, and removed by a surgical procedure involving a small access osteotomy of the mandibular ramus with removal of the cortical bone in order to enucleate the whole lesion [ncbi.nlm.nih.gov]

  The success rate following open procedures has ranged from 55% to 65%[13]. The remaining 35% to 45% of patients have had recurrence of the cyst, requiring additional open surgical procedures. [jpss.eu]

  The surgical procedure consisted of curettage with bone replacement and plugging. The postoperative course was uneventful with almost complete radiographic healing (Figure 7). [panafrican-med-journal.com]

  Surgical safety Though surgery for tumors is highly effective, we understand that any surgery can be a stressful experience for children and families. [chop.edu]

• Suggestibility

  On surgical exploration of her right mandibular lesion an empty cavity was found suggestive of traumatic bone cyst. The lesion healed completely after 1 year without loss of vitality of any teeth. [ncbi.nlm.nih.gov]

  This lesion is found in other skeletal bones as well and there is a suggestion of trauma commonly associated with these lesions. [homesteadschools.com]

• Aggressive Behavior

  Glandular odontogenic cyst is a rare developmental odontogenic cysts of the jaws having an aggressive behavior. The most common site of occurrence is the anterior mandible, and it is widely seen in middle-aged people. [ncbi.nlm.nih.gov]

  Almost all ABCs of the spine involve the posterior elements, and a high incidence of neurologic symptoms is observed, as well as more local aggressive behavior. [emedicine.medscape.com]

  Prognosis: - DF exhibits locally aggressive behavior without capacity to metastasize. - Recurrence following curretage and resection are 72% and 17% respectively. - Local relapse has been reported as late as eight years following primary surgery. [pedorthpath.com]

  CASE DESCRIPTION: An 18-year-old female patient presented with headaches and progressive neck pain. Imaging revealed a large cystic lesion involving the C1 lamina and right lateral mass. [ncbi.nlm.nih.gov]

It is therefore an integral part of the diagnostic workup when dealing with (myo)fibroblastic lesions of soft tissue and bone. Two cases of myositis ossificans with USP6 rearrangement were published so far. [ncbi.nlm.nih.gov]

It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. [ncbi.nlm.nih.gov]

BACKGROUND: Jaw pseudocysts are benign osseous lesions of unclear etiology. Among these, the simple bone cyst (SBC) and aneurysmal bone cyst (ABC) are intriguing bone pathologies still rarely studied together. [ncbi.nlm.nih.gov]

These results may suggest that venous obstruction of the lesions play an important role in the etiology of multiple simple cysts, as shown in typical bone cysts. [link.springer.com]
