Rectus Abdominis Muscle Endometriosis: A Unique Case Report with a Literature Review.

Introduction and importance: Extrapelvic endometriosis, confined exclusively to the body of the rectus abdominis muscle, is a rare form of abdominal wall endometriosis. While its etiopathology remains unclear, it is often diagnosed in healthy women who present with atypical symptoms and localization unrelated to any incision site, or in the absence of a history of endometriosis or previous surgery. Presentation of the case: Here, we describe a unique case of intramuscular endometriosis of the rectus abdominis muscle in a healthy 39-year-old Caucasian woman.

Atypical Plasma Cell Leukemia Mistaken for Acute Leukemia: A Case Report.

The patient we present here had many clinical, morphological, and laboratory findings characteristic of acute leukemia. During the course of the disease, the diagnosis changed from acute leukemia to chronic small B-cell lymphoproliferative disease, a blastoid variant of mantle cell lymphoma, and finally to atypical plasma cell leukemia. Atypical plasma cell leukemia is a rare condition with aggressive biological behavior.

Immunohistochemical and Histopathological Features of Persistent Gingival Enlargement in Relation to Metal Allergic Sensitisation during Orthodontic Treatment.

This study aimed to analyse the immunohistochemical profile of inflammatory infiltrates in the gingival tissue of patients undergoing orthodontic treatment in relation to patients’ titanium and/or nickel allergy status. Patients with gingival enlargement received initial periodontal therapy, followed by external gingivectomy in the case of persistent gingival enlargement. The sample included 44 patients (22 had metal allergic sensitisation).

Cardiomyocytes calpain 2 expression: Diagnostic forensic marker for sudden cardiac death caused by early myocardial ischemia and an indicator of the duration of myocardial agonal period?

Sudden cardiac death (SCD) is an unexpected natural death of cardiac etiology and occurs within one hour of the onset of cardiac symptoms in an apparently healthy subject or within 24 h if death is not witnessed. The diagnosis of early myocardial ischemia (EMI) or acute myocardial infarction (AMI) after death is a challenge for forensic pathologists especially when death occurs in a short period of time after the onset of myocardial ischemia. Disorder of cardiomyocytes Ca homeostasis caused by myocardial ischemia during SCD can lead to the activation of calcium-activated non-lysosomal cysteine protease, including calpains.

Osteopontin is associated with decreased apoptosis and αv integrin expression in lung adenocarcinoma.

Osteopontin (OPN) is a glycoprotein involved in invasion, progression and metastasis of many carcinomas. It contains several functional domains including binding sites for αv integrins, cell surface molecules playing a major role in mediating cell migration and adhesion. The aim of the study was to evaluate the expression of osteopontin in human non-small cell lung cancer (NSCLC) and to determine its possible prognostic significance as well as relation to apoptosis and αv integrin expression.
