Nareg Minaskeian, Patrick P Hu
Primary cardiac tumors are a rare occurrence with myxomas accounting for about half of the benign tumors. Once diagnosed, surgical resection is the standard of care. Our case describes a female in her 50s who underwent a myxoma resection under cardiopulmonary bypass via biatrial approach. Intraoperatively, the thin septal crux between the wall of the aorta and mitral valve was damaged during resection, requiring stem cell tissue matrix for repair. The patient also developed severe mitral regurgitation suggesting infarct to the left coronary system during resection, subsequently receiving a mechanical mitral valve and a saphenous vein bypass graft...

Benign myxomas are the most common among primary tumours in the left atrium of the heart and they usually require an urgent operative management. However, in times of constant ageing of the population and dealing with patients with severe concomitant diseases, an interesting question appears about the conservative approach. We present a case of 75-year-old woman, once diagnosed and operated on left atrium myxoma, with recurrent tumour in the site of resection found in control echocardiography 1,5 years later...

: Myxomatosis is a recurrent problem on rabbit farms throughout Europe despite the success of vaccines. To identify gene variations of field and vaccine strains that may be responsible for changes in virulence, immunomodulation, and immunoprotection, the genomes of 6 Myxoma virus strains (MYXV) were sequenced: German field isolates Munich-1, FLI-H, 2604, 3207, vaccine strain MAV, and challenge strain ZA. The analyzed genomes ranged from 147.6 kb (strain MAV) to 161.8 kb (strain 3207) in size...

This is the case report of a 65-year-old man who experienced left calf pain after spraining his left ankle. On magnetic resonance imaging (MRI), a well-defined fluid collection was identified, with low intensity on T1-weighted images and very high intensity on T2-weighted images. On certain slices, a soft tissue mass in the proximal fibula was identified. Following resection of the fibular lesion, histological examination confirmed a benign tumor with cystic elements, described in the current pathology and radiology literature as juxta-articular myxoma...

Myxomatosis and rabbit hemorrhagic disease (RHD) are the major viral diseases that affect the wild European rabbit (Oryctolagus cuniculus). These diseases arrived in Europe within the last decades and have caused wild rabbit populations to decline dramatically. Both viruses are currently considered to be endemic in the Iberian Peninsula; periodic outbreaks that strongly impact wild populations regularly occur. Myxoma virus (MV) and rabbit hemorrhagic disease virus (RHDV) alter the physiology of infected rabbits, resulting in physical deterioration...

Odontogenic Myxoma (OM) is a slow growing painless locally aggressive tumor seen in gnathic bones and is generally asymptomatic. OM is characterized by spindle, wedge or stellate shaped cells loosely arranged in an abundant mucoid stroma. It is found incidentally on radiographs and may vary from a unilocular radiolucency to a multilocular lesion with well-defined or diffuse margins. Treatment includes surgical management that may range from simple enucleation and curettage to surgical excision including peripheral osteotomy, segmental resection, hemimandibulectomy and maxillectomy...

CASE DESCRIPTION A 15-year-old neutered female mixed-breed dog (dog 1) and an 11-year-old neutered female Labrador Retriever (dog 2) were examined because of unilateral exophthalmus, third eyelid protrusion, and periorbital swelling that failed to respond to antimicrobial treatment. CLINICAL FINDINGS Both dogs underwent ultrasonographic, CT, and MRI examination of the head. In both dogs, advanced imaging revealed a poorly defined, peripherally contrast-enhancing, mucous-filled cystic mass that radiated from the temporomandibular joint and infiltrated the periorbital tissues and retrobulbar space...

BACKGROUND: Cardiac myxomas (CMs) are a major primary heart tumor which often causes unexpected symptoms or sudden death. Among CMs, biatrial myxomas are even rare. This study was designed to investigate the clinical characteristics and surgical treatment of 5 cases with biatrial myxoma, to summarize the treatment experience and the effect of short-to-mid-term prognosis. METHODS: Five patients with biatrial myxoma were included in this study. The patients' relative literature, chest X-ray, body-surface electrocardiogram, and ultrasonic cardiogram (UCG) were used to investigate the clinical characteristics...

In this study, the effect of active infection with vaccinia virus Western Reserve (VACV WR) on expression of C-type lectin domain family 2 (CLEC2D), a ligand of the human NK cell inhibitory receptor NKR-P1, was examined. As predicted, VACV infection led to a loss of CLEC2D mRNA in 221 cells, a B cell lymphoma line. Surprisingly, VACV infection of 221 cells caused a dramatic increase in cell surface staining for one CLEC2D-specific antibody, 4C7. There were no changes in other antibodies specific for CLEC2D and no indication that NK cells with NKR-P1A were inhibited, suggesting 4C7 detects a non-CLEC2D molecule following infection...

Objective: We aimed to present clinical features, surgical approaches, importance of surgical technique and long-term outcomes of our patients with cardiac myxoma who underwent surgery. Methods: We retrospectively collected data of patients with cardiac myxoma who underwent surgical resection between February 1990 and November 2014. Biatrial approach is the preferred surgical method in a large proportion of patients that are operated due to left atrial myxoma because it provides wider exposure than the uniatrial approach...

Neurothekeomas (NTKs) are benign cutaneous neoplasms of fibrohistiocytic origin and most commonly occur in the head, neck, and upper extremities. Traditionally, NTK and nerve sheath myxoma (NSM) were classified as subtypes of a single neoplasm with a common histogenesis, but recently immunostaining has demonstrated that the lesions are most likely of distinct cellular origin. Rarely, NTKs have been reported to occur in the ocular adnexa, and the present case of a 39-year-old female is the first to describe a cellular NTK originating in the cornea and mimicking a Salzmann's nodular degeneration...

Maxillary segmental defects are a reconstructive challenge particularly when the anterior arch is involved. Missing bone, mucosa, and teeth should be replaced; fistulae closure should be guaranteed by bone and mucosa continuity; stable functional occlusion should be achieved; and facial aesthetics restored. These defects resulting from tumor excisions, if left untreated, will cause additional problems related to interposed scar and collapse of lip and nose. Immediate reconstruction should avoid these problems and should be considered when safe tumor-free margins are obtained...

Echocardiographic diagnosis of atrial myxoma may not always be straightforward, and the distinction between myxoma and thrombi is not easy, especially when we observe a mass after successful surgery. Our report describes a 72-year-old woman who presented with right upper limb hemiparesis and was subsequently diagnosed as having transient ischemic attack due to a left atrial myxoma. One month after successful surgical resection of the tumor, the patient developed left-sided weakness. Echocardiography revealed a left atrial mass attached to the interatrial septum...

Objective: To investigate the clinicopathologic characteristics and differential diagnosis of dermal nerve sheath myxoma (DNSM) and neurothekeoma (NTK). Methods: Clinical, pathological features and immunohistochemical profiles in 9 cases of DNSM and 8 cases of NTK were comparatively studied. The literature was reviewed. Results: The involved site of 9 DNSMs included the hand/fingers (n=3), ear (n=2), face, back, abdominal wall and waist (1 case each). Two of 8 NTKs arose in the forearm (n=2), one each in the nose, lip, shoulder, supraclavicular region, leg and hand...
