41. Comparative Expression of CD34, Intercellular Adhesion Molecule-1, and Podoplanin and the Presence of Mast Cells in Periapical Granulomas, Cysts, and Residual Cysts. (Abstract)

Comparative Expression of CD34, Intercellular Adhesion Molecule-1, and Podoplanin and the Presence of Mast Cells in Periapical Granulomas, Cysts, and Residual Cysts. The aim of the present study was to compare the immunoexpression of CD34, intercellular adhesion molecule-1 (ICAM-1), and podoplanin and the presence of mast cells with clinical, demographic, radiologic, and histologic features from periapical granulomas, periapical cysts, and residual cysts.Thirty-one lesions (5 granulomas, 15 (...) periapical cysts, and 11 residual cysts) were selected. Histologic sections in silanized slides were used for the immunohistochemical reactions. The analysis of the images was performed by using an optical microscope, and data were analyzed with 5% significance (P < .05).Cysts presented atrophic and hyperplastic epithelium in 11 cases (35.5%) and 15 cases (48.8%), respectively (P > .05). The intensity of the inflammatory infiltrate was similar when comparing the 3 groups (P > .05). CD34 and podoplanin

43. Cyst infection in autosomal dominant polycystic kidney disease: penetration of meropenem into infected cysts. Full Text available with Trip Pro

Cyst infection in autosomal dominant polycystic kidney disease: penetration of meropenem into infected cysts. Cyst infection is a common and serious complication of autosomal dominant polycystic kidney disease (ADPKD) that is often refractory. Carbapenems are frequently needed to treat to patients with refractory cyst infection, but little is known about the penetration of newer water-soluble carbapenems into cysts. This study investigated the penetration of meropenem (MEPM) into infected cysts (...) in patients with ADPKD.Between August 2013 and January 2014, 10 ADPKD patients (14 infected cysts) receiving MEPM at Toranomon Hospital underwent drainage of infected cysts and definite cyst infection was confirmed through detection of neutrophils by cyst fluid analysis. The serum concentration of MEPM was measured just after intravenous administration and was compared with that in fluid aspirated from infected cysts.In the patients undergoing cyst drainage, the mean serum MEPM concentration was 35.2

44. Immunohistochemical Analysis of Galectins-1, -3, and -7 in Periapical Granulomas, Radicular Cysts, and Residual Radicular Cysts. (Abstract)

Immunohistochemical Analysis of Galectins-1, -3, and -7 in Periapical Granulomas, Radicular Cysts, and Residual Radicular Cysts. Galectins play important roles in immunoinflammatory responses, but their participation in the development of periapical lesions remains unclear. This study aimed to evaluate the expressions of galectins-1, -3, and -7 in periapical lesions, correlating them with the intensity of the inflammatory infiltrate and the pattern of the cystic epithelium.Twenty periapical (...) granulomas (PGs), 20 radicular cysts (RCs), and 20 residual radicular cysts (RRCs) were submitted to immunohistochemistry using anti-galectin-1, -3, and -7 antibodies. The percentage of immunopositive cells in epithelial and connective tissues was determined.In connective tissue, PGs exhibited higher cytoplasmic/membrane expression of galectins-1 and -7 than RCs and RRCs (P < .05). There was higher nuclear expression of galectin-1 in PGs compared with RCs and RRCs (P < .05). The expression of galectins-1

45. Confocal endomicroscopy and cyst fluid molecular analysis: Comprehensive evaluation of pancreatic cysts Full Text available with Trip Pro

Confocal endomicroscopy and cyst fluid molecular analysis: Comprehensive evaluation of pancreatic cysts Increases in the quality as well as utilization of cross-sectional imaging have led to rising diagnoses of pancreatic cystic lesions (PCL). Accurate presurgical diagnosis enables appropriate triage of PCLs. Unfortunately, current diagnostic approaches have suboptimal accuracy and may lead to unnecessary surgical resections or missed diagnoses of advanced neoplasia. Additionally, early (...) markers have also emerged as another diagnostic modality as the pattern of genetic alternations present in cyst fluid can provide both diagnostic and prognostic data. We propose that both techniques can be utilized to improve patient outcomes.

46. Coexisting sublingual dermoid cyst and heterotopic gastrointestinal cyst: Case report Full Text available with Trip Pro

Coexisting sublingual dermoid cyst and heterotopic gastrointestinal cyst: Case report A heterotopic oral gastrointestinal cyst coexisting with a lingual dermoid cyst is a rare condition, with only 3 reported cases in the English-language literature. Clinically, both gastrointestinal and dermoid cysts tend to manifest as an asymptomatic swelling. Cysts above the mylohyoid often present with sublingual swelling, whereas those below the mylohyoid present with submental swelling. Increased (...) salivation, altered speech, dyspnea and difficulties in eating, swallowing and respiration may be present, depending on the size of the cyst. This paper describes the case of a 4-year-old girl presenting with swelling of the tongue and floor of the mouth that interfered with normal speech. Two cystic lesions were surgically excised using an intraoral approach, and recovery was uneventful. Histopathological examination of the specimens taken during surgery revealed the first, anterior cyst to be a dermoid

47. Thyroid cyst mirror artifact mimicking a tracheal cyst on ultrasound in a patient with excessive trachea collapsibility Full Text available with Trip Pro

Thyroid cyst mirror artifact mimicking a tracheal cyst on ultrasound in a patient with excessive trachea collapsibility Mirror image artifact in ultrasound is not an unusual phenomenon. However, it is rarely seen in thyroid ultrasound because of the natural convexity of the tracheal surface. We report a mirror artifact during thyroid ultrasound in a patient with an excessively collapsible trachea. Minor pressure with the transducer made the trachea surface flat or concave, and then a cyst (...) in the thyroid was mirrored across the trachea, which mimicked an intratracheal cyst. This case illustrates how an unusual collapsible trachea can generate an image that simulates an intratracheal lesion during thyroid ultrasound.

48. Mycobiome of Cysts of the Soybean Cyst Nematode Under Long Term Crop Rotation Full Text available with Trip Pro

Mycobiome of Cysts of the Soybean Cyst Nematode Under Long Term Crop Rotation The soybean cyst nematode (SCN), Heterodera glycines Ichinohe (Phylum Nematoda), is a major pathogen of soybean. It causes substantial yield losses worldwide and is difficult to control because the cyst protects the eggs which can remain viable for nearly a decade. Crop rotation with non-host crops and use of biocontrol organisms such as fungi and bacteria offer promising approaches, but remain hampered by lack (...) of knowledge of the biology of nematode parasitic organisms. We used a high-throughput metabarcoding approach to characterize fungal communities associated with the SCN cyst, a microenvironment in soil that may harbor both nematode parasites and plant pathogens. SCN cysts were collected from a long-term crop rotation experiment in Southeastern Minnesota at three time points over two growing seasons to characterize diversity of fungi inhabiting cysts and to examine how crop rotation and seasonal variation

Meibomian cyst (chalazion) Meibomian cyst (chalazion) - NICE CKS Share Meibomian cyst (chalazion): Summary A meibomian cyst (also known as a chalazion) is a sterile, chronic, inflammatory granuloma of the eyelid caused by a foreign body reaction to sebum within a meibomian gland. Meibomian cysts can occur in all age groups (but are thought to be most common in adults) and are a frequent cause of lumps in the eyelid. Pregnant women and people with the following conditions are more at risk (...) of meibomium cysts (and their recurrence): Blepharitis. Seborrhoeic dermatitis. Rosacea. Diabetes mellitus. Elevated serum cholesterol. A meibomian cyst rarely causes serious complications. A meibomian cyst typically presents as a firm, painless, localized eyelid swelling that develops slowly over several weeks. Cysts are more common on the upper than the lower eyelid. They are usually 2–8 mm in diameter. One or both eyes can be affected. More than one meibomian cyst may be present. When the eyelid

51. New insights of the local immune response against both fertile and infertile hydatid cysts. Full Text available with Trip Pro

New insights of the local immune response against both fertile and infertile hydatid cysts. Cystic echinococcosis is caused by the metacestode of the zoonotic flatworm Echinococcus granulosus. Within the viscera of the intermediate host, the metacestode grows as a unilocular cyst known as hydatid cyst. This cyst is comprised of two layers of parasite origin: germinal and laminated layers, and one of host origin: the adventitial layer, that encapsulates the parasite. This adventitial layer (...) is composed of collagen fibers, epithelioid cells, eosinophils and lymphocytes. To establish itself inside the host, the germinal layer produces the laminated layer, and to continue its life cycle, generates protoscoleces. Some cysts are unable to produce protoscoleces, and are defined as infertile cysts. The molecular mechanisms involved in cyst fertility are not clear, however, the host immune response could play a crucial role.We collected hydatid cysts from both liver and lungs of slaughtered cattle

54. An infected urachal cyst presenting as acute abdominal pain in a child: A case report. Full Text available with Trip Pro

An infected urachal cyst presenting as acute abdominal pain in a child: A case report. Urachal cyst is an exceptionally rare disease in children caused by the incomplete obliteration of the urachal remnant. Urachal cysts seldom cause symptoms unless a secondary infection occurs. The symptoms of an infected urachal cyst are nonspecific and may be similar to acute appendicitis or other acute abdominal conditions. However, complications attributable to a delayed diagnosis can endanger the life (...) the urachal cyst because of its high sensitivity and nonradioactive characteristic, and computed tomography is a typical diagnostic tool for urachal cysts. The mainstream management of an infected urachal cyst remains surgical excision. Complete excision of urachal cysts is relatively easy in a pediatric patient and the risk of subsequent infection is low; however, patients tend to have a low, although possible, risk of potential malignant transformation over their lifetimes.

55. MRI findings of an atypical testicular epidermoid cyst: A case report. Full Text available with Trip Pro

MRI findings of an atypical testicular epidermoid cyst: A case report. Typical testicular epidermoid cysts (TECs) manifestate as a target sign or onion skin sign on ultrasonography and magnetic resonance (MR) imaging. Clinicians are increasingly aware of the imaging characteristics of typical TECs, which allow accurate diagnosis and successful treatment while preserving the testicle, but atypical TECs are likely to be misdiagnosed as a malignant intratesticular neoplasm, leading to complete (...) testicular resection.A 26 year-old male patient complained of a painless enlargement of the left testicle that had been present for 1 month. The patient had no recent medical history of scrotal trauma or systemic infection.A round 48 mm × 45 mm × 43 mm mass was seen inside the left testicle.

57. Intralobar pulmonary sequestration with cystic degeneration mimicking a bronchogenic cyst in an elderly patient: A case report and literature review. Full Text available with Trip Pro

Intralobar pulmonary sequestration with cystic degeneration mimicking a bronchogenic cyst in an elderly patient: A case report and literature review. Pulmonary sequestration (PS) is a rare congenital malformation defined as nonfunctioning lung tissue supplied by systemic circulation. It is uncommonly diagnosed in adults. Herein, we describe a clinical case of PS with cystic degeneration mimicking a bronchogenic cyst in an elderly patient.A huge cystic mass was incidentally found in a 65-year (...) -old man on chest computed tomography (CT) scans during preoperative workup for a hand laceration. A 15-cm-sized round cystic mass was detected in the right lower lobe.After reviewing the chest CT scan, we decided to perform contrast-enhanced chest magnetic resonance imaging (MRI) and CT-guided lung aspiration biopsy. On MRI, the lesion had the appearance of a cystic mass with hemorrhagic clots, such as an intrapulmonary bronchogenic cyst. The aspirated specimen was nondiagnostic; thus, we decided

Dermoid cyst with secretion of CA 19-9 detected by 18F-FDG PET/CT: A case report. Carbohydrate antigen 19-9 (CA 19-9) is a tumor glycolipid, frequently elevated in the serum of patients due to malignancies from gastrointestinal organs; in particular, the pancreas. This carbohydrate antigen is also expressed in benign diseases.A case of a 27-year-old female who has an unknown origin CA 19-9 elevation for 2 years.After the left ovarian cystectomy and microscopic examination, the final diagnosis (...) is a dermoid cyst. The dermoid cyst shows increased F-fluorodeoxyglucose (F-FDG) uptake in the F-FDG positron emission tomography (PET)/computed tomography (CT) study.The laparoscopic oophorocystectomy was performed. It was observed that the patient's CA 19-9 level returned to normal after the surgery 6 months later. This showed that the dermoid cyst was responsible for the abnormal CA 19-9 level.In this case, we can learn that the F-FDG PET/CT scan has potential use in patients with unknown origin
