Unexpected posterior mediastinal mass: A case report and literature review.

Introduction: Glomangioma is an uncommon hypervascular tumor typically found in the extremities, with primary occurrences in the mediastinum being exceedingly rare.

Case Presentation: A 38-year-old male presented to our cardio-thoracic surgery department with chest pain. Chest computed tomography (CT) revealed a 45 mm posterior paravertebral right solidocystic mass, a finding confirmed by Magnetic resonance imaging (MRI) with a solidocystic mass in the posterior paravertebral right pleura suggesting a fibrous tumor exhibiting cystic degeneration.

PIK3CA mutations in breast cancer: A Tunisian series.

Background: The aim of this study was to analyze PIK3CA mutations in exons 9 and 20 in breast cancers (BCs) and their association with clinicopathological characteristics.

Methods: Mutational analysis of PIK3CA exon 9 and 20 was performed by Sanger sequencing in 54 primary BCs of Tunisian women. The associations of PIK3CA mutations with clinicopathological characteristics were analyzed.

Pathologically confirmed women's breast cancer: A descriptive study of Tunisian and Algerian series.

Background: Breast cancer (BC) is the most frequent malignancy among women in Tunisia and Algeria. Clinical and pathological characteristics of this cancer among these populations are not widely reported. The aim of the study was to report clinical and pathological characteristics of women's BC in a Tunisian and Algerian series.

A rare case report of sacral epidural angiolipoma: Diagnosis and treatment.

Background: Spinal angiolipomas are rare benign tumors composed of mature adipose tissue and anomalous vascular channels. The sacral localization is extremely rare. To the best of our knowledge, there have been only two cases reported in the literature.

New-onset guttate psoriasis secondary to COVID-19.

SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), is associated with flares of psoriasis in patients with well-documented disease. Both viral infection and medications used for treatment, like hydroxychloroquine, were incriminated. Herein, we report the case of a 25-year-old male patient who presented a first-onset guttate psoriasis following a COVID-19 infection.

Hemorrhagic synovial cyst: An unexpected cause of acute cervical spinal cord compression. Case report.

Introduction: Cervical synovial cysts are uncommon. They are most often responsible for a chronic clinical picture. Rarely, intracystic hemorrhage occurs, and may acutely present as radicular - or even spinal cord compression syndrome leading to irreversible neurological impairment.

Multiple endocrine neoplasia type 1 revealed by a hip pathologic fracture.

Multiple endocrine neoplasia type 1 is a rare autosomal inherited syndrome that affects a variety of endocrine tissues such as the parathyroid, endocrine pancreas, and anterior pituitary. Osseous complications are often misdiagnosed. We presented a case of a 46-year-old woman with pathological fractures of the lower limb.

Transformation of a prostatic adenocarcinoma into squamous cell carcinoma after luteinizing hormone-releasing hormone (LHRH) agonist and radiotherapy treatment.

Squamous cell carcinoma of the prostate is rare and represents 0.5% to 1% of prostatic carcinomas. Transformation of prostatic adenocarcinoma into squamous cell carcinoma after LH-RH agonist intake has been reported in only 8 cases in the literature.

Paratesticular Angiomyofibroblastoma-Like Tumor: Unusual Case of a Solidocystic Form.

The angiomyofibroblastoma-like tumor of the male genital tract is a rare benign tumor. A total of 34 cases have been reported in the literature. We herein report an exceptional case of solidocystic form in its paratesticular location, in a 79-year-old man.

Reclassification of gastrointestinal mesenchymal tumors.

Background: Gastrointestinal stromal tumors - commonly called GISTs - are rare; yet, they represent an important type of mensenchymal tumors arising within the gastrointestinal tract. The acronym GIST was introduced in 1998 to define a well established pathological entity which bears a highly specific marker called KIT (CD117). Scientific interest for these tumors in recent years is mainly due to the progress in identification by immunohistochemistry and the advent of targeted molecular therapy.
