Ewing’s sarcoma is a primary bone cancer that mainly affects the long bones. This malignancy is particularly common in pediatric patients. Primary cranial involvement accounts for 1% of cases, with occipital involvement considered extremely rare. In this case study, primary occipital Ewing’s sarcoma with a posterior fossa mass and subsequent relapse resulting in spinal seeding is reported. A 3-year-old patient presented with a 1-year history of left-sided headaches, localized over the occipital bone with progressive torticollis. Computed tomography (CT) imaging showed a mass in the left posterior fossa compressing the brainstem. The patient then underwent surgical excision followed by adjuvant chemoradiation therapy. Two years later, the patient presented with severe lower back pain and urinary incontinence. Whole-spine magnetic resonance imaging (MRI) showed cerebrospinal fluid (CSF) seeding from the L5 to the S4 vertebrae. Primary cranial Ewing’s sarcoma is considered in the differential diagnosis of children with extra-axial posterior fossa mass associated with destructive permeative bone lesions. Although primary cranial Ewing’s sarcoma typically has good prognosis, our patient developed metastasis in the lower spine. Therefore, with CNS Ewing’s sarcoma, screening of the entire neural axis should be taken into consideration for early detection of CSF seeding metastasis in order to decrease the associated morbidity and mortality.

Background: Primary Ewing’s sarcoma (ES) is typically seen within the long bones, vertebrae, or pelvis. Uncommonly, it can be found within the cranium among the rarest locations for primary ES are the skull base, in particular, the petroclival bone. Case Description: The patient is a 68-year-old female with past medical history of Stage III breast cancer who presented with severe retro-orbital headache and diplopia due to a cranial nerve VI palsy. Magnetic resonance imaging (MRI) revealed a mass at the left petroclival bone with extension into the adjacent left petrous apex and into the posterior aspect of the left cavernous sinus proximal to the carotid artery. The patient subsequently underwent an endoscopic transsphenoidal biopsy. Pathological and molecular analysis supported a diagnosis of ES. The patient then underwent neoadjuvant chemotherapy and radiotherapy. At 12 month-follow-up, her petroclival ES demonstrated significant interval decrease in size on MRI surveillance imaging. Conclusions: This is the third case of primary ES of the petroclival bone to be reported in the literature. In this patient, management consisted of surgical incisional biopsy followed by adjuvant radiation and chemotherapy. Knowledge and awareness of this type of tumor is important for the skull base surgeon.

Ewing’s sarcoma is a rare and aggressive tumor that typically arises in the long bones of the extremities. It belongs in the family of small round blue cell tumors and is characterized immunohistochemically by diffuse CD99 expression and molecularly by one of several oncogenic translocations, most commonly t(11;22)(q24;q12) between the <i>EWSR1</i> gene and the <i>FLI1</i> gene. Here we present a rare case of Ewing’s sarcoma in the sinonasal tract with <i>FUS-ERG</i> gene arrangement that was regarded for almost a decade as a sinonasal-type hemangiopericytoma (glomangiopericytoma). This case illustrates the surprisingly prolonged natural history of Ewing’s sarcoma that did not receive therapy for many years and the importance of considering alternative genetic translocations. Our experience suggests that the presence of diffuse CD99 membranous staining pattern in a small blue round cell tumor with morphology typical for Ewing’s sarcoma but FISH negative for <i>EWSR1</i> rearrangement should prompt consideration of <i>FUS-ERG</i> fusion.

Introduction. A glomus tumor is a benign vascular tumor derived from glomus cells and occurs mainly in the subcutaneous layer of the subungual or digital pulp. Extradigital glomus tumors have been reported within the palm, wrist, forearm, foot, bone, stomach, colon, cervix, and mesentery. Glomus tumors can originate from the intraosseous, intramuscular, periosteal, intravascular, and intraneural layers. However, a glomus tumor originating from the intravascular layer of the forearm is a rare condition.Case Report. A 44-year-old woman had a 7-year history of chronic pain and focal tenderness of the forearm. No hypersensitivity or sensory alterations were observed. Contrast magnetic resonance imaging (MRI) showed a mass measuring 5 × 3 × 2 mm leading to a vein. Surgical excision was performed, and the tumor was completely resected. Finding of gross examination revealed a dark-red, well-defined soft tissue tumor, and histologic examination confirmed that the mass was a glomus tumor. The patient’s symptoms were completely resolved postoperatively.Conclusion. Intravascular glomus tumors rarely occur in the forearm; therefore, a thorough physical exam, comprehensive medical history, in-depth imaging, and early surgical excision upon clinical suspicion may be helpful to prevent a delayed or incorrect diagnosis.

Spinal Epidural

A 65-year-old male with a history of hypertension presents to the emergency department (ED) with new onset of non-traumatic back pain. The patient is investigated for life-threatening diagnoses and screened for “red flag symptoms,” including fever, neurologic abnormalities, bowel/bladder symptoms, and a history of injectiondrug use (IVDU). The patient is treated symptomatically and discharged home but represents to the ED three additional times, each time with new and progressive symptoms. At the time of admission, he is unable to ambulate, has perineal anesthesia, and 500 cc of urinary retention. Whole spine magnetic resonance imaging (MRI) confirms a thoracic spinal epidural abscess. This case, and many like it, prompts the questions: when should emergency physicians consider the diagnosis of a spinal epidural abscess, and what is the appropriate evaluation of these patients in the ED? (Figure 1).

A retrospective case review was carried out to report the outcomes in a contemporary case series of Ewing’s sarcoma originating in the hand. We identified five patients treated since 1995. All five had wide surgical excision, one by ray amputation. All were treated with chemotherapy. Four patients also received radiation therapy, two to treat metastases and two as an adjunct to local excision. There were no local recurrences. Two patients developed metastases. Both died of their disease. Neither of these two patients had received local postoperative radiation therapy; one did not receive chemotherapy before definitive surgery. The other three patients were alive and free of disease at last follow-up, 4 to 12 years after initial presentation.

Four cases of a locally invasive sarcoma of the chest wall are described in children aged between 8 and 14 years. Although its morphology resembles a Ewing's sarcoma of bone there are light and electron microscopical features that are distinctive. The sarcoma is thought to represent an entity which has not previously been defined. Its clinical importance lies in the fact that the prognosis with appropriate treatment appears to be good. One child died after 2 1/2 years, but the others are alive 6, 8, and 16 years after presentation.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

Background. Conventional osteochondromas are common bone lesions developing in the metaphyseal region of growing skeleton. Marginal excision is the treatment of choice for such tumours. Extraosseous cartilaginous tumours are rare and their biological potential is poorly characterized.Case Presentation. A-52-year old woman presented with 3-year history of fullness and dull pain and inability to flex her left knee, sit cross-legged, or squat. Clinical and imaging studies revealed a nodular mineralised mass in the anterior portion of the knee displacing the patellar tendon laterally. Excision biopsy confirmed the diagnosis of extraosseous osteochondroma-like soft tissue mass. There is no recurrence at two-year followup.Conclusion. An integrated clinicopathological diagnosis helps to clarify the nature of extraosseous cartilaginous tumour that can arise at an unusual anatomic site. Complete surgical excision is the treatment of choice.

We report a case of limited stage Ewing's sarcoma which was initially treated as chronic osteomyelitis for 3 years. A 24-year-old man presented with a one-week history of pain in the right arm and fever, with histology suggestive of osteomyelitis of the affected humerus. He developed multiple relapses of pain and fever; each episode responded to antibiotic treatment. A second biopsy was performed 3 years later and confirmed a diagnosis of Ewing's sarcoma. Despite a 3-year delay in diagnosis, the disease remained localised. This case report highlights an atypical facet of the natural history of Ewing's sarcoma: a response to antibiotic and anti-inflammatory agents, and the limited stage of the disease despite a misdiagnosis of 3 years. This suggests the possibility that anti-inflammatory agents exert an inhibitory effect on the tumour growth. We also highlight the newer histologic and immunologic staining used in the diagnosis of Ewing's sarcoma.

Background and Importance: Sacrococcygeal Teratoma (SCT) with medular invasion is rare. Case Presentation: We report a case of an 11-month male infant, with no prenatal history of any abnormality, presenting since birth, a mass in the buttock extended to retrorectum associated with a right side hypotonic limb and monoplegia. Medullar and abdominal pelvic Magnetic Resonance Imaging (MRI) showed a sacrococcygeal tissue mass and intradural lumbosacral invasion with a high level of alpha-fetoprotein. Surgical excision was done successfully with an uneventful follow-up. Conclusion: Despite of the intradural invasion, those SCT are in major cases mature and present low risk of malignancy or recurrence.
