Introduction: Chondromyxoid fibroma (CMF) is an uncommon benign tumor accounts for <2% of all benign and <1% all bone tumors. It is a cartilage tumor with myxoid and fibrous elements. Because of rarity and resemblance with other benign and malignant tumor, diagnosis of this tumor always remains challenging. Often, this lesion affects metaphysis of long growing bones of children and young adults. Common locations of this tumor are around the growth plate of proximal tibia and fibula and distal femur. Case Report: A 21-year-old male presented to orthopedic outpatient department with a history of the left hip pain for 1 year, following a trivial fall before 1 year. The patient was not able to do heavy strenuous activities such as running, jumping, and other sports activities. Terminal range of movements were painful. Magnetic resonance imaging suggested of cystic lesion involving synovial lining near head-and-neck junction of the left femur. Curettage of the lesion was done. The bone defect was not found to be large enough to be filled with bone graft. Histopathological examination showed lobular pattern with stellate to spindle-shaped cells on the myxoid background. Conclusion: CMF of subcapital region of femoral neck is an extremely unusual presentation. When occurring in middle-aged persons and in uncommon locations, this can raise suspicion of chondrosarcoma. Although intralesional curettage has the risk of recurrence in post-operative period, sufficient and careful curettage and excision of lesion will be enough to treat these benign lesions with good prognosis.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

AbstractBackground: Known also as Osler’s triad, Austrian syndrome is a complex pathology which consists of pneumonia, meningitis and endocarditis, all caused by the haematogenous dissemination of Streptococcus pneumoniae. The multivalvular lesions are responsible for a severe and potential lethal outcome.Case report: The case of a 51-year-old female patient, with a past medical history of splenectomy, is presented. She developed bronchopneumonia, acute meningitis and infective endocarditis as a result of Streptococcus pneumoniae infection and subsequently developed multiple organ dysfunction syndromes which led to a fatal outcome. Bacteriological tests did not reveal the etiological agent. The histopathological examination showed a severe multivalvular endocarditis, while a PCR based molecular analysis from formalin fixed valvular tissue identified Streptococcus pneumoniae as the etiologic agent.Conclusions: The presented case shows a rare syndrome with a high risk of morbidity and mortality. Following the broad-spectrum treatment and intensive therapeutic support, the patient made unfavourable progress which raised differential diagnosis problems. In this case, the post-mortem diagnosis demonstrated multiple valvular lesions occurred as a result of endocarditis.

Important Differential Diagnosis

An osseous choristoma is a benign tumor consisting of regular bone tissue in an irregular localization. Choristomas in the head and neck region are rare. Most frequently, they are found in the region of the tongue or oral mucosa. There are also very few reports on osseous choristomas in the submandibular region. We present the case of a woman with a large, caudal osseous choristoma within the lateral cervical triangle. Literature review is given about all of the reported cases in the region of the neck. The pathogenesis is yet unexplained. Our case supports the theory that the development of an osseous choristoma is a reaction to a former trauma. Cervical osseous choristomas are seldom, but they represent an important differential diagnosis when dealing with a cervical tumor.

Introduction.Osteoma of the temporal bone is a very uncommon benign tumor of bone. Osteomas may occur in the external auditory canals but are reported to be very rare in the mastoid bone.Case Report.A 36-year-old male presented to our department with a hard swelling behind the right ear diagnosed as osteoma. Complete excision was done through a postauricular approach. Histopathology confirmed the diagnosis of osteoma.Conclusion.Osteomas, although rare, should be considered when dealing with any hard mastoid swelling. Complete removal can be ensured by drilling till the normal cortical bone is reached to avoid recurrence. A cortical mastoidectomy should be done if the mastoid air cell system is involved.

Abstract Background Invasive fungal infections (IFIs) are uncommon infections that account for approximately 27.2/100,000 cases per year in the United States. One form of IFI is chronic invasive fungal sinusitis (CIFS). If untreated, invasion into neighboring structures may cause altered mental status, seizures, strokes, proptosis, and intracranial complications. Case Report An afebrile 43-year-old female with a history of polysubstance abuse presented to the ED due to altered mental status, left sided facial droop, right sided hemiparesis, and slurred speech. The patient was somnolent but arousable to stimuli and appeared acutely ill. The patient’s mother reported a history of cocaine abuse, which was confirmed on urine toxicology. A CT head and neck with contrast revealed subacute basal ganglia lacunar infarcts and a left sphenoid opacity with scattered hyperintensities and erosive changes [Figure 2]. One month prior, she had been diagnosed with a left superior pole kidney mass and a left-sided enlarged periaortic lymph node containing multiple noncaseating granulomas and GMS stains positive for fungal hyphae [Figure 1]. The patient underwent nasal endoscopy with tissue biopsy. Tissue showed necrotizing invasive fungal sinusitis with granuloma formation and foreign-body giant cell reaction. Fungal speciation of the tissue culture showed Curvularia species was placed on IV voriconazole. While the infection stabilized, her neurologic deficits did not significantly improve. She was discharged to inpatient rehabilitation. Figure 1. Coronal and axial view of left upper pole kidney mass with perinephric fat stranding. Figure 2. MRI brain CTA Head and Neck with contrast in axial plane showing multifocal infarcts likely represent complications of fungal basilar meningitis secondary to the left sphenoid sinus disease. Imaging also shows irregular erosive change at the anterior aspect of the sella turcica, through the planum sphenoidale, and bony defect of the sphenoid sinus. Methods Results Conclusion Intranasal use of cocaine causes vasoconstriction to elicit sinonasal tissue ischemia. With extended use, chronic mucosal inflammation can occur that can result in sinonasal osteocartilaginous necrosis and potential for infection. CIFS is infrequently diagnosed and its indolent nature with progression over weeks or months can make diagnosis and treatment difficult. The most frequent fungal species identified are the Aspergillus species, but Curvularia species have been found as well. CT and MRI scanning can be suggestive, but are not sufficiently specific or sensitive. The main forms of interventional modalities include surgical debridement and antifungal therapy to maximize survival Disclosures All Authors: No reported disclosures

<p class="abstract">Amyloidosis represents a diverse group of disorders that have in common the deposition of amyloid protein in various extracellular tissues. Its clinical presentation may be systemic or localised. However, regions in the head and neck are rarely affected. This report discusses the case of a 57 year old man with a history of 6 years of left ear non-pulsatile tinnitus, who at the physical examination presented a polilobulated, yellowish oropharyngeal lesion, behind the left posterior pillar of the tonsil. Biopsy of the lesion sustained the diagnostic of light chain amyloidosis and subsequent evaluation was significant for establishing the diagnosis of localised amyloidosis. While further investigations a second laryngeal lesion was encountered. We present a case report of double synchronous amyloidosis localization on head and neck and asymptomatic lesions and discuss the implications for diagnosis and treatment.</p>

The separation of the follicle from around the crown of an unerupted tooth causes formation of dentigerous cyst. It may undergo metaplasia in several cases. In this case a 30 year old female patient reported with a history of dentigerous cyst with respect to impacted 48. The swelling started growing gradually causing facial asymmetry. On intraoral examination the swelling seem to extend from 48 to 46 region and cortical plates were expanded. The histopathological examination revealed the sample to be cystic ameloblastoma (mural variety). This paper sends a message that the potential of a cyst should never be understated, instead it must be kept in an observation or understanding the biological behavior over a course of time.
