Toxic Epidermal Necrolysis Induced by Doxycycline: A Case Report and Literature Review.

Lyell syndrome, also known as toxic epidermal necrolysis (TEN), is a rare but life-threatening skin condition, often triggered by certain medications. Antiepileptics, allopurinol, and some nonsteroidal anti-inflammatory drugs are the most common causes. Some antibiotics are also common culprits, although tetracyclines are rarely linked to this condition.

Migrating foreign material mimicking metastatic soft tissue sarcoma in a patient with history of synthol injection.

Injecting substances like Synthol for cosmetic muscle enhancement is known, but its potential for causing severe systemic complications is less documented. This case highlights the risks of foreign material migration, initially presenting as a suspected malignancy. A 47-year-old male presented with dyspnea and bilateral diffuse airspace opacities on chest X-ray, initially raising suspicions for metastatic disease.

FISH analyses for 1p and 19q status on gliomas: Reporting an 8 years' experience from a tertiary care center in the Middle East.

Diffuse gliomas are the most common primary malignancies of the central nervous system (CNS). The 2016 edition of the World Health Organization (WHO) classification of CNS tumors opted to integrate current molecular data with the traditional histologic diagnosis in the definition of the disease. This integrated diagnosis offers a greater level of objectivity and helps in establishing more definitive diagnoses for tumors that may have been controversial on histology alone.

Helicobacter pylori Prevalence in Laparoscopic Sleeve Gastrectomy Specimen.

Introduction: Laparoscopic sleeve gastrectomy (LSG) has become a common surgical procedure. The value of routine histopathologic examination of the LSG specimens remains, however, a controversial issue. Helicobacter pylori was the most prevalent finding in several previous studies, but the overall results were dissimilar.

Pancreatic sarcoidosis mimicking neoplasia: Case report.

Introduction: Although sarcoidosis rarely involves the pancreas, such involvement may mimic pancreatic cancer. We herein report a case of pancreatic sarcoidosis giving rise to a cancer-mimicking retention cyst, concomitant with a neuroendocrine adenoma.

Presentation Of Case: A 47-year-old Caucasian male presented to follow-up for a benign-appearing cyst of the tail of the pancreas, detected incidentally on CT scan done for a urinary stone in 2017.

Elbow Cystic Lymphangioma in an 8-Month-Old Boy.

Cystic lymphangiomas are benign tumors originating mainly in the head and neck of the pediatric population. The authors report a rare case of cystic lymphangioma in the right elbow of an 8-month-old baby treated successfully by complete surgical resection.

A Case Report of Meningeal Hemangiopericytoma: A 9-Year Journey from the Brain to the Spine.

Background: Hemangiopericytomas (HPCs) are rare and aggressive vascular mesenchymal tumors. Unlike meningiomas, which have a similar radiologic appearance, these tumors have a higher risk of local recurrence after resection, and distant metastasis can reach up to 23%. Metastases to the vertebral bones from an intracranial HPC are very rare, with so far only 9 cases reported in the literature.

Calcaneus Metastasis from Follicular Thyroid Carcinoma 12 Years after Total Thyroidectomy.

We report the case of a sixty-eight-year-old female patient who presented for left ankle pain; X-rays and MRI showed a benign calcaneal cyst, found to be delayed distant metastasis from primary papillary thyroid carcinoma. Patient required surgical excision of the cyst. Results of histological examination showed metastatic papillary thyroid carcinoma.

Intramasseteric Schwanoma mimicking an isolated cheek mass: Case report and review of literature.

Introduction: Schwannoma is a benign well circumscribed tumor of the nerve sheath and it is mostly localized in the head and neck. Intramasseteric schwannoma represents a very rare entity and a few cases have been described in the literature.

Presentation Of Case: We present a case of an isolated, asymptomatic and slowly progressive right cheek tumor in a middle aged man.

Metachronous, Single Metastasis to the Parotid, from Primary Breast Cancer: A Case Report and Review of the Literature.

Background. The parotid gland is an unusual site for metastatic disease and when metastasis occurs, it commonly originates from head and neck primaries. Spread from distant infraclavicular sites such as the breast, into the parotid, is even more unusual with very few cases reported in the literature.

Complete remission of peritonitis in a patient with luteinized thecomas of the type typically associated with sclerosing peritonitis using GnRH agonist and anti-estrogen.

•-We report a case of luteinized thecomas associated with sclerosing peritonitis (LTSP).•-Sclerosing peritonitis associated with LTSP is a main cause of mortality and morbidity.•-LTSP can be successfully treated with GnRH agonist and anti-estrogen.

Phospho-MEK1/2 and uPAR Expression Determine Sensitivity of AML Blasts to a Urokinase-Activated Anthrax Lethal Toxin (PrAgU2/LF).

In this study, we attempt to target both the urokinase plasminogen activator and the mitogen-activated protein kinase pathway in acute myeloid leukemia (AML) cell lines and primary AML blasts using PrAgU2/LF, a urokinase-activated anthrax lethal toxin. PrAgU2/LF was cytotoxic to five out of nine AML cell lines. Cytotoxicity of PrAgU2/LF appeared to be nonapoptotic and was associated with MAPK activation and urokinase activity because all the PrAgU2/LF-sensitive cell lines showed both uPAR expression and high levels of MEK1/2 phosphorylation.

Influence of proton pump inhibitors on gastritis diagnosis and pathologic gastric changes.

Aim: To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia.

Methods: Chronic PPI use is associated with masking of H.

Atypical choroid plexus papilloma treated with single agent bevacizumab.

Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages. Papillomas have an indolent course and carry a good long-term outcome if gross total surgical resection is achieved.

StarD13 is a tumor suppressor in breast cancer that regulates cell motility and invasion.

Breast cancer is one of the most commonly diagnosed cancers in women around the world. In general, the more aggressive the tumor, the more rapidly it grows and the more likely it metastasizes. Members of the Rho subfamily of small GTP-binding proteins (GTPases) play a central role in breast cancer cell motility and metastasis.

Bifocal Presentation of Primary Testicular Extranasal NK/T-Cell Lymphoma: A Case Report and Review of the Literature.

Introduction. Testicular lymphoma is an aggressive disease with a very poor prognosis. Nasal-type natural killer/T-cell lymphoma (NKTCL-N) in particular is very uncommon and has a rapidly progressive, fatal course.

Metastatic parotid myoepithelial carcinoma in a 7-year-old boy.

Myoepithelial carcinoma is a rare malignancy of the parotid gland that is usually seen in adults. We report the first case in children of myoepithelial carcinoma of the parotid gland with massive invasion of the facial nerve and metastasis to cervical lymph nodes. Due to its rarity, the treatment and the clinical course of this tumor are not well defined yet.

Pathology of the liver in obese and diabetic ob/ob and db/db mice fed a standard or high-calorie diet.

Non-alcoholic fatty liver disease (NAFLD) is one of the commonest liver diseases in Western countries. Although leptin deficient ob/ob and db/db mice are frequently used as murine models of NAFLD, an exhaustive characterization of their hepatic lesions has not been reported to date, particularly under calorie overconsumption. Thus, liver lesions were characterized in 78 ob/ob and db/db mice fed either a standard or high-calorie (HC) diet, for one or three months.

Flat epithelial atypia of the breast.

"Flat epithelial atypia" is the adopted term by the WHO working group on breast tumor referring to an early neoplastic breast lesion affecting the terminal duct-lobular units. Pathologists have described this lesion under a variety of names including columnar cell lesions and low-grade clinging carcinoma in situ. It is usually encountered on breast biopsies performed for mammographically-identified microcalcifications.

Gene expression profiling in breast cancer.

Gene expression profiling has been increasingly used to determine new cancer markers. This technology holds major promises for improving the management of patients with breast cancer in which traditional clinicopathologic parameters do not account for all the heterogeneity of this disease and its distinct prognostic groups. Gene expression profiling has resulted in new classification of breast cancer and new assays are being developed and commercialized as prognostic and predictive tests.

Measurement of macromolecular diffusion coefficients in human tumors.

The diffusive transport of macromolecules in tumors is an important determinant of the delivery of many anticancer therapeutics. However, measurements of diffusive transport to date have only been performed in animal models. In this work, diffusion coefficients of BSA and IgM were measured in human tumor biopsies (cooled to 4-7 degrees C to prevent degradation) using fluorescence recovery after photobleaching.
