Hepatorenal fibrocystic disease (HRFCD) is characterized by cysts in the kidney and liver with associated fibrosis and is the result of defects in proteins required for cilia function or assembly. Previous reports indicate that macrophages, mainly M2-like macrophages, contribute to HRFCD, although the origin (yolk-sac derived resident macrophages vs bone-marrow derived infiltrating macrophages) and contribution of these cells to the observed phenotypes is unknown. Herein, we utilize a congenital model of cilia dysfunction (IFT88Orpk ) to study the importance of macrophages in HRFCD...

Objective There remains confusion between Langer's lines and wrinkle lines with respect to the optimal orientation of elliptical excisions on the trunk. This study sought to determine the directions of wound closure that would result in least wound tension after skin lesion excisions. Materials and methods Some 1181 consecutive skin lesion excisions were investigated (age range 13-95 years, median 64 years) using a tensiometer to determine directions of least wound tension. These lines were mapped. Skin tension measurements were taken during the procedure and analysed...

Angiomyxomas are uncommon myxoid tumours arising most commonly from the pelvis. A 46-year-old woman with a history of polycystic kidney disease presented asymptomatically for surveillance ultrasonography; changes were noted in the size and morphology of her liver cysts. Subsequent radiological assessment displayed features suspicious of malignancy and a right hemihepatectomy was performed with curative intent. Pathological examination of the resected specimen found histology consistent with an angiomyxoma arising primarily from the liver parenchyma...

Epidermoid cyst of the presacral space is a rare congenital lesion of ectodermal origin. Presacral epidermoid cysts have been previously reported in women, however are extremely rare in males. We report a case of presacral epidermoid cyst in a 55-year-old male who presented to our emergency department with acute urinary retention and history of chronic constipation. A non-contrast computed tomography scan was performed with suspicion of urolithiasis, which revealed a well circumscribed low attenuation presacral mass...

Pancreatic pseudocysts and walled-off pancreatic necrosis arise as a complication of pancreatitis. Multiple fluid collections are seen in 5-20% of the patients who have walled-off peripancreatic fluid collections. There is a paucity of data regarding the role of endoscopic transmural drainage in the management of multiple pancreatic fluid collections. In this case report, we present the case of a 72-year-old male with three walled-off pancreatic fluid collections in the setting of acute necrotizing pancreatitis...

Background: Although it is well known that most choroid plexus cysts (CPCs) are asymptomatic, previous studies have reported that they can infrequently cause progressive hydrocephalus along with their increasing sizes. Among those cases, some patients needed cyst fenestration or cerebrospinal fluid (CSF) diversion to recover neurological deterioration. Meanwhile, some CPCs revealed spontaneous resolution, and in rare cases, they developed re-accumulation. Some reports have described series of radiological findings about their changes in location...

The pathogenesis of thyroid lymphoepithelial cysts is controversial, and two hypotheses have been proposed, namely derivation from branchial-derived remnants or from squamous metaplasia of the follicular cells. The aim of this study was to clarify the pathogenesis of thyroid lymphoepithelial cysts. We performed pathological and immunohistochemical examination of 21 thyroid lymphoepithelial cysts, 13 non-neoplastic squamous metaplasia samples without thyroid carcinoma, 13 solid cell nests, and 14 lateral cervical cysts...

BACKGROUND: Autosomal Recessive Polycystic Kidney Disease (ARPKD) is associated with significant mortality and morbidity and there are currently no disease-specific treatments available for ARPKD patients. One major limitation in establishing new therapies for ARPKD is a lack of sensitive measures of kidney disease progression. Magnetic Resonance Imaging (MRI) can provide multiple quantitative assessments of disease. METHODS: We applied quantitative image analysis of high resolution (non-contrast) T2-weighted MRI techniques to study cystic kidney disease progression and response to therapy in the PCK rat model of ARPKD...

RATIONALE: Pancreatic alveolar echinococcosis (AE) is an exceptionally rare disease; no more than 10 cases have been published to date. It is characterized as extensive local tissue infringement and destruction; thus, extended surgical resection, such as duodenopancreatectomy, is often needed to obtain a negative resection margin so as to improve the long-term outcome and prognosis. PATIENT CONCERNS: A middle-aged Tibetan man was admitted due to a 16-year history of recurrent pain in the right upper abdomen...

Following the discovery of (R)-roscovitine's beneficial effects in three polycystic kidney disease (PKD) mouse models, cyclin-dependent kinases (CDKs) inhibitors are investigated as potential treatments. We have used various affinity chromatography approaches to identify the molecular targets of roscovitine and its more potent analogue (S)-CR8 in human and murine polycystic kidneys. These methods revealed casein kinases 1 (CK1) as additional targets of the two drugs. CK1ε expression at the mRNA and protein levels is enhanced in polycystic kidneys of 11 different PKD mouse models, as well as in human polycystic kidneys...

Birt-Hogg-Dubé syndrome (BHD, also referred to as Hornstein-Knickenberg syndrome) is an autosomal dominant tumor syndrome caused by mutations in the FLCN gene located on chromosome 17. Depending on their age, patients with BHD may exhibit various clinical signs and symptoms. Disease severity can vary greatly among members of the same family. Early symptoms include basal lung cysts, which can lead to recurrent spontaneous pneumothoraces. The majority of patients (> 90 %) develop multiple fibrofolliculomas, especially on the face and upper trunk, in the second or third decade of life...

Clitoral phimosis or preputial fusion may occur as a result of atrophic vaginitis among other conditions. A 72-year-old woman presented with atrophic vaginitis, preputial fusion, and a painful periclitorial pseudocyst. We suggest that a minimal surgery approach in a manual retraction of the synarchies without making an incision is a gentle and effective surgical management of preputial fusion. Suturing the ends from each other combined with continuous topical prophylaxis will minimise the risk of recurrence of pseudo-cyst and prevent worsening scar tissue formation...

The present case describes an unusual lactation of a 15-month-old,unbred Holstein-Friesian heifer, which had four swollen, ampouleshaped udder quarters with milk secretion. Examination of the heifer using rectal palpation and transrectal ultrasonography revealed enlargement of the right ovary and partial replacement of original tissue by multiple cysts of variable size. Treatment of the assumed follicularcystic ovary disease was unsuccessful. At slaughter 8 months later, the ovaries were examined pathologically and a granulosa cell tumor on the right ovary was diagnosed...

Adrenal pseudocysts are rare entities, which are usually asymptomatic. Large symptomatic adrenal pseudocysts may cause compressive symptoms. The etiology of these cysts is unknown, although the cyst wall is all lined by fibrous tissue, without any epithelial or endothelial lining. We report a case of a 26-year-old lady who presented with a symptomatic right adrenal pseudocyst measuring 7.6 cm in size. Magnetic resonance imaging confirmed the presence of a right retroperitoneal cystic lesion which was hyperintense on T2 sequencing...
