Plasma cell granuloma (PCG) is an uncommon benign tumor of unknown etiology, primarily located in the lungs. We report a case of PCG on the gingiva mimicking benign and malignant tumors in a 56-year-old woman. Histopathological examination revealed a relatively sharp circumscribed inflammatory cell infiltration under the mucosa-containing plasma cells, predominantly those including Russell bodies. Plasma cells are stained by CD138 immunohistochemistry. Polyclonal status of the lesion was confirmed by kappa and lambda light chaining...

A 61-year-old man was evaluated for a 2 month history of cough and dyspnea without relevant exposures other than pyrethrin containing insecticidal sprays he used while grooming dogs almost daily. High Resolution Computed Tomography (HRCT) of the chest demonstrated a Non-Specific Interstitial Pneumonia (NSIP) pattern. Pulmonary function testing revealed an isolated mildly reduced diffusion capacity. Bronchoalveolar lavage (BAL) results confirmed the presence of foamy histiocytes, lymphocytes, and polymorphonuclear cells consistent with ongoing exposure...

Lobular capillary haemangioma (LCH), previously known as pyogenic granuloma, is a benign vascular lesion commonly found within the oral and nasal cavity. However, it is rarely encountered within the trachea, where presenting features include recurrent haemoptysis, cough, and wheeze. We here describe a case of a 7 mm tracheal LCH in a 56-year-old woman, which was successfully resected at interventional bronchoscopy using biopsy forceps. Clinicians should be aware of tracheal LCH in the differential diagnosis for recurrent haemoptysis...

Mycobacterium tuberculosis (MTB) has long been known to persist in grossly normal tissues even in people with active lesions and granulomas in other parts of the body. We recently reported that post-primary TB begins as an asymptomatic infection that slowly progresses, accumulating materials for a massive necrotizing reaction that results in cavitation. This paper explores the possible roles of trehalose 6,6' dimycolate (TDM) or cord factor in the ability of MTB to persist in such lesions without producing inflammation...

Trehalose 6,6'dimycolate (TDM) is a glycolipid found in nearly pure form on the surface of virulent Mycobacterium tuberculosis (MTB). This manuscript investigated the production of TDM, growth rate and colony morphology of multiple strains of MTB, each of which had been isolated from both pulmonary (sputum) and extrapulmonary sites of multiple patients. Since sputum contains MTB primarily from cavities and extrapulmonary biopsies are typically granulomas, this provided an opportunity to compare the behavior of single strains of MTB that had been isolated from cavities and granulomas...

The role of T helper-17 (Th17) lymphocytes in the regulation of Schistosoma mansoni Soluble Egg Ags (SEA)-induced granuloma is unknown. The present study examined the effect of Th17 cytokines (IL-17 and IL-22) on granulocytes recruitment and functions during SEA-induced granuloma formation in vitro in Schistosoma-infected and non-infected individuals. Granulocytes were isolated from 27 Schistosoma-infected patients and 13 controls and were used for granuloma induction using SEA-conjugated polyacrylamide beads in the presence of Th17 cytokines...

Endometritis is nowadays rare in developed countries and typically shows a subclinical or mild course; therefore, there are probably more cases of endometritis than diagnosed but they lack clinical relevance. In the fertile period of life it can be the reason for vaginal bleeding and infertility. The most common causes for non-specific endometritis are residual placental tissue after abortion or childbirth, intrauterine interventions, lesions within the uterine cavity, such as endometrial polyps, endometrial hyperplasia and neoplasms, intrauterine devices (IUD) and cervical stenosis...

We report a case of pulmonary cryptococcoma, in an adult with recently detected diabetes, mimicking as lung cancer. A 45-year-old gentleman with past history of pulmonary tuberculosis presented with fever, cough with expectoration, pleuritic chest pain and hemoptysis. Chest radiograph and computed tomography revealed right lower lobe mass which significantly enhanced on contrast administration. Ultrasound guided biopsy was done which on histopathological examination showed non-necrotizing granulomas with narrow-based budding yeast cells suggestive of cryptococcosis...

Background: Mycobacterial culture is the gold standard test for diagnosing tuberculosis (TB), but it is time-consuming. Polymerase chain reaction (PCR) is a highly sensitive and specific method that can reduce the time required for diagnosis. The diagnostic efficacy of PCR differs, so this study determined the actual sensitivity of TB-PCR in tissue specimens. Materials and Methods: We retrospectively reviewed 574 cases. The results of the nested PCR of the IS6110 gene, mycobacterial culture, TB-specific antigen-induced interferon-γ release assay (IGRA), acid-fast bacilli (AFB) staining, and histological findings were evaluated...

A 19-year-old male with diarrhea, abdominal pain, fever, and elevated C-reactive protein (CRP) levels was admitted to our hospital. Endoscopic examination and small intestinal contrast radiography revealed multiple longitudinal ulcers in the large intestine and ileum. A specimen biopsied from one of these ulcers revealed non-caseating epithelioid cell granuloma. He also had a draining anal fistula. Plain chest computed tomography (CT) and abdominal contrast-enhanced CT did not reveal any vascular abnormality...

An 83-year-old male presented with distended abdomen. A computed tomography scan demonstrated pleural effusion, ascites, peritoneal thickness, and panniculitis. Multiple small white nodules of peritoneum were observed during a laparoscopy examination, and biopsy specimens revealed noncaseating granulomas. Gallium scintigram demonstrated an accumulation in the peritoneum and revealed a panda sign that has been described as an indication of sarcoidosis. Although sarcoidosis rarely induces peritonitis with ascites, peritoneal sarcoidosis was diagnosed and he began receiving steroid therapy...

BACKGROUND: As an intracellular human pathogen, Mycobacterium tuberculosis (Mtb) is facing multiple stressful stimuli inside the macrophage and the granuloma. Understanding Mtb responses to stress is essential to identify new virulence factors and pathways that play a role in the survival of the tubercle bacillus. The main goal of this study was to map the regulatory networks of differentially expressed (DE) transcripts in Mtb upon various forms of genotoxic stress. We exposed Mtb cells to oxidative (H2O2 or paraquat), nitrosative (DETA/NO), or alkylation (MNNG) stress or mitomycin C, inducing double-strand breaks in the DNA...

The non-Hodgkin's lymphoma (NHLs) is a diverse group of lymphoid neoplasms, prevalence of which increased since three decades. NHL is diverse in the manner of presentation, response to various treatment and prognosis. NHL usually involves not only lymph nodes but also extranodal sites. Usually, oral manifestation of NHL is secondary to the widespread involvement throughout the body. Oral NHL is relatively rare and difficult to diagnose in clinical setting as it presents as local swelling, pain, discomfort and mimics pyogenic granuloma, periodontal disease, osteomyelitis and other malignancies...

The hallmark feature of Mycobacterium tuberculosis (M.tb) the causative agent of human tuberculosis, is its complex lipid rich cell wall comprised primarily of mycolic acids, long chain fatty acids that play a key role in structural stability and permeability of the cell wall. In addition, they are involved in inhibiting phagosome-lysosome fusion and aid in granuloma formation during the pathogenic process. M.tb DesA1 is an essential acyl-acyl carrier protein desaturase predicted to catalyze the introduction of position specific double bonds during the biosynthesis of mycolic acids...
