PURPOSE: The purpose of the study was to evaluate the characteristics of sebaceous gland carcinoma (SGC) of the ocular adnexae, which is due to a high variability in clinical, histological and immunohistochemical characteristics often challenging to diagnose. METHODS: Records of six patients with SGC were reviewed, who underwent surgical excision and who were histologically diagnosed with SGC. For comparison, there were specimens from four patients with basal cell carcinoma (BCC) and four patients with squamous cell carcinoma (SCC)...

Since the 1960s, silicone implants have been used for breast augmentations, both cosmetically and in reconstructive surgery. Tissue exposed to silicone can react with multiple adverse advents. Autoimmune/inflammatory syndrome induced by adjuvants due to silicone exposure from ruptured silicone implants can lead to different interstitial lung manifestations predominantly with granuloma evolvement, leading to the so-called silicone implant incompatibility syndrome (SIIS). This case describes a 57-year-old woman with multiple lung infiltrations and a left-sided breast implant...

Snoring and the subsequent diagnosis of obstructive sleep apnea (OSA) was a life-threatening medical condition with no available treatment until the late 20th century. An early description of OSA was provided by Charles Dickens in his 1836 novel Pickwick Papers with the description of a "fat boy" who was thought to be lazy and always falling asleep but likely displayed hypersomnolence from OSA. It was not until 1976 that Ikematsu first described uvulopalatopharyngoplasty (UPPP) as an alternative surgical treatment of "snoring," with a reported cure rate of 81%...

A 64-year-old woman with metastatic clear cell renal carcinoma who had been on nivolumab immunotherapy for 10 months was referred for a FDG PET scan to monitor disease progress. New bilateral mediastinal and hilar FDG-avid lymphadenopathy was noted. Pathology on subsequent mediastinal nodal biopsy showed well-formed epithelioid granulomas with no evidence of malignancy consistent with sarcoidosis. This case illustrates that pulmonary sarcoidosis can be induced by immunotherapy in the treatment of renal cell carcinoma...

BACKGROUND: Mycetoma is a chronic, proliferative lesion of cutaneous/subcutaneous tissue characterized by draining tracts and granules in the discharge caused by actinomycetes (actinomycetoma) or filamentous fungi (eumycotic mycetoma). OBJECTIVES: This case report describes the unusual finding of a cutaneous mycetoma of the lateral wing of the right nostril in a gelding. ANIMAL: A 16-year-old Fjord gelding with suspected pituitary pars intermedia dysfunction (PPID) was presented for evaluation of a nonpainful, firm and raised mass involving the lateral wing of the right nostril and the lip...

Mahmoud H El Kouni
Schistosomes are responsible for the parasitic disease schistosomiasis, an acute and chronic parasitic ailment that affects more than 240 million people in 70 countries worldwide. It is the second most devastating parasitic disease after malaria. At least 200,000 deaths per year are associated with the disease. In the absence of the availability of vaccines, chemotherapy is the main stay for combating schistosomiasis. The antischistosomal arsenal is currently limited to a single drug, Praziquantel, which is quite effective with a single-day treatment and virtually no host-toxicity...

Isolates of the Mycobacterium tuberculosis lineage 2/East-Asian are considered one of the most successful strains due to their increased pathogenicity, hyper-virulence associated with drug resistance, and high transmission. Recent studies in Colombia have shown that the Beijing-like genotype is associated with multidrug-resistance and high prevalence in the southwest of the country, but the genetic basis of its success in dissemination is unknown. In contribution to this matter, we obtained the whole sequences of six genomes of clinical isolates assigned to the Beijing-like genotype...

Three contradictory clinical presentations of gout have puzzled clinicians and basic scientists for some time: first, the crescendo of sterile inflammation in acute gouty arthritis; second, its spontaneous resolution, despite monosodium urate (MSU) crystal persistence in the synovium; and third, immune anergy to MSU crystal masses observed in tophaceous or visceral gout. Here, we provide an update on the molecular pathophysiology of these gout manifestations, namely, how MSU crystals can trigger the auto-amplification loop of necroinflammation underlying the crescendo of acute gouty arthritis...

It has been suggested that the predilection of sarcoidosis to affect scars is due to the presence of antigens or foreign bodies that can serve as a stimulus for granuloma formation. Several patients with sarcoidosis-specific skin lesions in venous puncture sites have been reported. However, in these patients the pathogenesis of the cutaneous lesions is not clear because the presence of foreign bodies is not to be expected. Our objective was to describe 3 patients who developed specific lesions of sarcoidosis in areas of venipuncture and to discuss their possible pathogenesis...

BACKGROUND: Chronic periapical lesions (CPLs) are common lesions of the oral cavity and are the result of caries, tooth fracture, iatrogenic causes or factors causing contamination and pulp necrosis. Inflammatory cells participate in the expansion of CPLs by releasing factors that stimulate or inhibit osteolytic activity. The objective of this study was to investigate the participation of RANKL, TNF-α, cathepsin K, IL-33 and OPG in the development of radicular cysts (RCs) and periapical granulomas (PGs)...

In recent years, there is a growing evidence that using 5-aminolevulinic acid (5-ALA)-guided resection of a cerebral glioblastoma, associated with chemoradiotherapy determine a prolonged survival of these patients, even though this period do not exceed 15 months. 5-ALA is a natural biochemical precursor of heme that is metabolized to fluorescent porphyrins, particularly protoporphyrin IX (PPIX) and no foreign reaction were noted until now. However, foreign body reaction developing in neurosurgery is documented in a few number of cases to suture material, surgical hemostatic material, or surgical glove starch, but up to now we could not find any article about granulomatous inflammation to polyglycolic acid (PGA) suture after brain tumor resection...

INTRODUCTION AND OBJECTIVE: Sarcoidosis is a systemic granulomatous disease predominantly affecting the lungs, although granulomas can also involve all other organs. Fortunately, it is often a self-limiting disease and aggressive treatment is not indicated in majority of cases. However, treatment is recommended when critical organs are affected or the disease is progressive. So far, there is lack of reliable information regarding the frequency of treatment in Caucasian population or data are discordant...

Diagnostic studies performed by cone beam computed tomography Morita 3D made possible to obtain high resolution images of hard tissues of upper jawbone and maxillary sinus, to detect bony tissue defects, such as odontogenic cysts, cystogranulomas and granulomas. High-resolution and three dimensional tomographic image reconstructions allowed for optimal and prompt determination of the scope of surgical treatment and planning of effective conservative treatment regimen. Interactive diagnostics helped to estimate cosmetic and functional results of surgical treatment, to prevent the occurrence of surgical complications, and to evaluate the efficacy of conservative treatment...

Severe dermatophyte infection is rare in immunocompetent adults. Recently cases have been described in travelers returning from South East Asia (Luchsinger et al., 2015) [1]. These may be sexually transmitted and can have permanent sequelae. We describe the first reported case of Majocchi's granuloma (MG) in an Australian returned traveler and its subsequent transmission via sexual contact. Both patients were successfully treated with systemic antifungals. MG should be considered in patients with severe rash after travel to South East Asia...

Microvascular networks in the adventitia of large arteries control access of inflammatory cells to the inner wall layers (media and intima) and thus protect the immune privilege of the aorta and its major branches. In autoimmune vasculitis giant cell arteritis (GCA), CD4 T helper 1 (TH1) and TH17 cells invade into the wall of the aorta and large elastic arteries to form tissue-destructive granulomas. Whether the disease microenvironment provides instructive cues for vasculitogenic T cells is unknown. We report that adventitial microvascular endothelial cells (mvECs) perform immunoregulatory functions by up-regulating the expression of the Notch ligand Jagged1...

RATIONALE: Congenital tuberculosis (TB) is described as a rare, but severe disease. In contrast to the cases with severe symptoms reported so far, we describe a child with asymptomatic congenital TB. PATIENT CONCERNS: An 8-week-old girl was investigated because of newly diagnosed TB in her mother, which complained about cough since 21 weeks gestation. Lung biopsy tissue specimens of the mother revealed necrotizing granuloma with a single acid-fast bacillus (AFB) and Mycobacterium tuberculosis (MTB) was detected by polymerase chain reaction...
