Lanthanum (La) deposition has been observed in gastrointestinal mucosa of dialysis patients treated with La carbonate to treat hyperphosphatemia in the 6 years since its authorization in Japan. We investigated gastrointestinal biopsies from 112 dialysis patients, and found 15 cases of histiocytic aggregation with crystalloids and one case of duodenitis with histiocyte aggregation without crystalloids in the 30 patients treated with La carbonate. No histiocytic lesions were observed in the 82 patients without La carbonate administration...

Soft tissue, or cutaneous, myoepitheliomas are rare tumors arising solely from a myoepithelial origin. These neoplasms are typically associated with uncertain differentiation and can contain cellular morphologies that include spindle, plasmacytoid, epithelioid, or clear cell forms. Soft tissue myoepitheliomas are commonly found on the lower limbs and in the pelvic girdle but can occur throughout the body. A small minority display heterogenous differentiation, typically osseous or cartilaginous in nature. Squamous and adipocytic cell types are much rarer...

BACKGROUND: Understanding the molecular pathogenesis of distinct phenotypes in human benign prostatic hyperplasia (BPH) is essential to improving therapeutic intervention. Current therapies target smooth muscle and luminal epithelia for relief of lower urinary tract symptoms (LUTS) due to BPH, but basal cell hyperplasia (BCH) remains untargeted. The incidence of has been reported at 8-10%, but a molecular and cellular characterization has not been performed on this phenotype. METHODS: Using freshly digested tissue from surgical specimens, we performed RNA-seq analysis of flow cytometry-purified basal epithelia from 3 patients with and 4 patients without a majority BCH phenotype...

Background: Adrenal incidentaloma refers to the incidental finding of a tumor in the adrenal gland, where nonfunctional forms are the most common variant. Myelolipoma is a rare (0.08-0.4%) occurrence characterized by adipose and hematopoietic tissue. The aim of this case report is to describe the diagnosis and appropriate management of a myelolipoma in an asymptomatic patient, which was originally considered an incidental hepatic hemangioma prior to being identified as a giant adrenal adenoma. Case description: The patient was a 54 year old obese female with a recent diagnosis of diabetes type II and dyslipidemia with recent ultrasound imaging suggestive of a hepatic hemangioma...

Mammary-like glands are a normal anatomical component of the anogenital region. The tumors occurring in them morphologically mimic the similar diseases of the breast. The paper presents a case of vulvar fibroadenoma with leaf-like outgrowths and apocrine metaplasia in a 38-year-old female patient. It describes the clinical and morphological characteristics of fibroadenomas and benign phyllodes tumors in the anogenital region.

A hallmark of immunity to worm infections and many allergies is a strong type 2 immune response. This is characterized by the production of cytokines interleukin-5 (IL-5) and IL-13 by adaptive T helper 2 (TH2) cells and/or type 2 innate lymphoid cells. Peroxisome proliferator activated receptor-γ (PPAR-γ) is typically regarded as an anti-inflammatory factor. We report that TH2 cells express high levels of PPAR-γ in response to the allergen house dust mite and after infection with the parasite Heligmosomoides polygyrus Mice lacking PPAR-γ in T cells failed to effectively differentiate into IL-5- and IL-13-secreting cells and, hence, did not develop TH2 cell-associated pathologies, including goblet cell metaplasia and eosinophilia, in response to allergen challenge...

BACKGROUND: Previous studies have focused on the presence of reflux in selected cohorts with pancreaticobiliary maljunction (PBM), but little is known regarding the wider incidence of occult reflux and associated mucosal changes. We aimed to correlate gallbladder mucosal abnormalities with objective evidence of PBM and occult pancreaticobiliary reflux (PBR) in an Australian population undergoing cholecystectomy. METHODS: Patients undergoing cholecystectomy between September 2010 and September 2012 were eligible for inclusion...

Epithelial- lined (true) cysts are rare lesions and until now the only information we had about their histogenesis was based on the analysis of a few cases. We retrospectively reviewed 8 cases of cysts with a true epithelial lining (confirmed immunohistochemically). The pathological findings and immunohistochemical analysis of the epithelial linings allowed for categorization of the cysts into 3 groups. Five cysts had pure mesothelial lining, which was flattened to cuboidal, and demonstrated a positive reaction for mesothelial markers (eg...

German cockroaches are major household allergens that can trigger allergic airway inflammatory diseases with sensitive T-cell responses. Although the use of immune modulatory biologics, such as antibodies, to mediate allergic responses has recently been examined, only systemic administration is available because of the size limitations on intranasal administration. Here we utilized a cell-permeable peptide, dNP2, to deliver the cytoplasmic domain of cytotoxic T-lymphocyte antigen-4 (ctCTLA-4) through the airway epithelium to modulate Th2 responses in a German cockroach extract (GCE)-induced allergic airway inflammation model...

OBJECTIVE: Chronic pancreatitis (CP) and autoimmune pancreatitis (AIP) are characterised by different inflammatory processes. If pancreatic inflammation is a prerequisite for autoimmunity is still unclear. AIP is considered mostly a T cell-mediated disease; however, in induction of CP, macrophages play a pivotal role. p21-a member of cyclin-dependent kinase inhibitors-can influence inflammatory processes, in particular can regulate T cell activation and promote macrophage development...

Although its prevalence is declining, gastric cancer remains a significant public health issue. The bacterium Helicobacter pylori is known to colonize the human stomach and induce chronic atrophic gastritis, intestinal metaplasia, and gastric cancer. Results using a Mongolian gerbil model revealed that H. pylori infection increased the incidence of carcinogen-induced adenocarcinoma, whereas curative treatment of H. pylori significantly lowered cancer incidence. Furthermore, some epidemiological studies have shown that eradication of H...

BACKGROUND AND AIM: Liquid nitrogen cryotherapy (LNC) allows increased depth of ablation compared to radiofrequency ablation (RFA) in Barrett's esophagus (BE). Expert centers may use LNC over RFA to ablate Barrett's esophagus after endoscopic resection of intramucosal cancer (IMCA). The aim of our study was to: 1) evaluate the safety and efficacy of LNC ablation in patients with BE and IMCA and 2) to evaluate the progression to invasive disease despite therapy. METHODS: This was a multicenter, retrospective study of consecutive patients with BE who received LNC following endoscopic mucosal resection (EMR) of IMCA...

The replacement of the entire or extensive parts of endometrial lining by stratified squamous epithelium is a rare entity known as ichthyosis uteri. It is considered to be a benign condition but may be associated with dysplastic changes and primary squamous cell carcinoma of the endometrium. Its association with endometrial adenocarcinoma is very rare. The aetiology of this condition is not clearly understood till date. We report a case of ichthyosis uteri associated with endometrial adenocarcinoma in a 70-year-old female who presented with complaint of per-vaginal bleeding for six months and underwent hysterectomy after being diagnosed with endometrial carcinoma...

A 37-year-old woman underwent surgery to remove bilateral vulvar masses. The masses were firm, non-tender, and immobile. Pathologic finding was a well-delineated creamy grayish mass with a homogenous grayish solid surface and mild edema, chronic inflammatory infiltration, and focal dilation of the ducts with squamous metaplasia. The diagnosis was hyperplastic and hypertrophied Bartholin's gland. Hyperplasia is a rare etiology for an enlarged Bartholin's gland. Clinical presentation of Bartholin's gland nodular hyperplasia is rather specific, although inflammatory lesion is the most common cause of swelling of the Bartholin's gland in all age groups...
