Desmoplastic Small Round Cell Tumor Presenting as an Intra/Extracranial Mass.

Desmoplastic small round cell tumors (DSRCTs) are highly malignant tumors, with distinct reciprocal chromosome translocation (11;22)(p13;q12). Intracranial metastasis is a very rare complication of this tumor, with only a few cases reported in the literature. To our knowledge, this is the only case presenting an extracranial extension of intracranial metastasis of DSRCT.

An unusual non-hematopoietic bone marrow finding.

We present an interesting case that showed a non-hematopoietic structure embedded in the bone marrow biopsy. Given the clinical and morphological difficulties, it was challenging to identify this artifact's nature. Publishing this case would familiarize pathologists with this artifact and save additional testing and delays in reporting.

Skeletal Mets From Squamous Cell Carcinoma of the Lower Limb: A Case Report.

Squamous cell carcinoma (SCC) is the second most common non-melanoma skin cancer worldwide and one of the most capable of metastasis. The bone is a common metastatic site of cancers, which is a major cause of morbidity, with an estimated 350,000 people dying yearly from bone metastases. However, bone metastasis from an SCC in the lower limb is rarely reported in the literature and the role of systemic chemotherapy is not well established.

Skin Metastasis Occurring 30 Years After Thyroidectomy for Papillary Thyroid Carcinoma.

The skin is an extremely rare site of metastasis from papillary thyroid carcinoma (PTC) and is linked to underlying disseminated malignancy, which reflects a dismal prognosis. We present the case of a 70-years-old Saudi female who presented at our clinic with an eight-month history of two painful and itchy skin nodules over the scalp and the medial aspect of the right arm. She had a history of total thyroidectomy for PTC 30 years prior.

Aspirin prescribing pattern and guidelines-adherence evaluation for primary prevention of cardiovascular diseases at a teaching hospital.

The present study investigates the aspirin prescribing pattern and guidelines-adherence evaluation for primary prevention of cardiovascular diseases at a teaching hospital. A total of 816 patients were included in the study, the patients who received aspirin aged 60-69 (29.65%), followed by patients aged 50-59 years old (29.

Screening for Cognitive Dysfunction in Amphetamine Users in Saudi Arabia; a Case-control Investigation Using Propensity Score Matching Analysis.

Amphetamine users have deficits in cognitive performance; however, the effects of duration and amount of use on cognitive decline remain elusive. The aim of this study was to evaluate the correlates of cognitive functioning in amphetamine users in Saudi Arabia. This was a case-control community-based study, using an Arabic adaptation of Addenbrooke's Cognitive Examination (ACE).

Low Grade Primary Leiomyosarcoma of the Right Atrium: Promising Survival with Complete Surgical Resection.

Primary cardiac leiomyosarcoma has an extremely low incidence with overall median survival of approximately 6 months. Here, We report the case of a 60-year-old man who underwent complete surgical excision of right atrial mass. Histologic examination revealed leiomyosarcoma.

Spheno-orbital juvenile psammomatoid ossifying fibroma: a case report and literature review.

Ossifying fibroma (OF) is an uncommon benign fibro-osseous lesion. Based on its clinical, morphological, and radiological features, OF is further divided into cemento-ossifying fibroma (COF), juvenile psammomatoid ossifying fibroma (JPOF), and juvenile trabecular ossifying fibroma (JTOF). JPOF rarely involves the cranial base, with limited reports published on spheno-orbital JPOF.

Frequent and differential mutations of the CYLD gene in basal cell salivary neoplasms: linkage to tumor development and progression.

Basal cell salivary neoplasms display similar cyto-morphologic features and are classified into adenoma and adenocarcinoma based on the presence or absence of tumor invasion at diagnosis. These neoplasms also share considerable phenotypic resemblance and co-exist with certain dermal adnexal tumors harboring the CYLD gene mutations inferring common genetic association. We sequenced the CYLD gene in both basal cell adenomas and adenocarcinomas and correlated the findings with CYLD, NF-κB, and β-catenin expression levels and clinicopathologic factors.

Diabetes Insipidus and Sclerosing Cholangitis in a child may be a clue to the diagnosis of Langerhans' Cell Histiocytosis: A Case Report.

Langerhans cell histiocytosis (LCH) is a rare disease that usually affects children and young adults. Sclerosing cholangitis (SC) can occur in 10-15% of patients with disseminated form of the disease. Central diabetes insipidus (CDI) is a rare disorder that may be caused by a variety of diseases mainly LCH and germinoma especially in children.
