A rare clinical case of systemic AA amyloidosis with cardiac involvement complicating ankylosing spondylitis: a case report.

Background: Ankylosing spondylitis (AS) is a type of chronic inflammation that is most prevalent in young adults and is characterized by an inflammatory enthesiopathy that gradually develops toward ossification and ankylosis. If inflammation is left unchecked, it can potentially lead to complications such as secondary amyloidosis, also known as AA amyloidosis, involving the deposition of amyloid serum A protein. Our case presents with a thyroid localization of AA amyloidosis which is secondary to this AS.

Ki-67 proliferation index to further stratify invasive breast cancer molecular subtypes: Northern African comparative cohort-study with external TCGA-BRCA and METABRIC validation.

Introduction: breast cancer (BC) is a malignancy with very high incidence and mortality in Africa, especially in Western Africa, where more than 25 thousand deaths are registered every year. Not all BC have the same prognosis, and being able to personalize treatment and predict aggressiveness is of crucial importance. The purpose of our study is to explore further subdivisions associated with prognosis, beyond breast cancer molecular classification that is routinely established in pathology departments.

Diagnostic imaging of foot mycetomas: A report on two cases.

Mycetomas caused by aerobic actinomycetes are called actinomycetomas. It is primarily localized in subcutaneous tissue but it can spread to different tissue planes including the skin, deep tissues and structures and eventually the bones. We report the cases of 2 patients referred for evaluation of soft tissue masses involving the foot.

Bone choristoma of the gingiva: A case report.

Introduction: Bone choristoma is a benign tumor with normal histology and ectopic location. This paper aims to report a rare case of bone choristoma in the maxillary gingival location.

Observation: The authors report a case of a 39-year-old woman, with a history of maxillary full edentulousness, who consulted for a slight pain evolved for about six months, triggered by movements on the lesion.

The solitary plasmacytoma of mandible: A case report.

Background: the solitary plasmacytomas entities characterized by the neoplastic proliferation of a single clone of plasma cells, typically producing a monoclonal immunoglobulin. It represents less than 5% of plasma cell dyscrasias. The most common sites of solitary plasmacytomas are long bones.

A rare cause of cervical swelling: Solitary plexiform neurofibroma.

Introduction: Plexiform cervical neurofibromas are benign neoplasm, extremely rare, difficult to diagnose and to manage. Only some cases have been reported in the literature.

Case Presentation: We report the case of a 60-year-old man admitted for a lateral neck mass, for which the surgical indication was the increase in volume of this mass, as well as the aesthetical impairment, the surgical exploration found the tumor attached to the cervical plexus.

Endoscopic resection of solitary fibrous tumor of the ethmoid: Case report review of the literature.

Introduction: Solitary fibrous tumour (SFT), as are benign neoplasms of fibroblastic cells. Nasosinusal localisation is exremely rare, difficult to diagnose and to manage.

Case Report: We report a rare case of Solitary fibrous tumour in the nasal cavity in a 47-year-old- woman, with complete surgical resection.

Primary Malignant Deciduoid Mesothelioma: A Challenging Diagnosis.

Primary malignant deciduoid mesothelioma is a rare subtype of epithelioid mesothelioma that was first described in the peritoneum in young women without a history of asbestos exposure. It was thought to be a distinct clinicopathologic entity with ominous prognosis; recent studies have better characterized this entity. On morphology, primary malignant deciduoid mesothelioma is characterized by cytomorphologic features resembling decidualized tissue.

[Astroblastoma: A rare glial tumor].

Astroblastoma is a rare neuroepithelial tumor most commonly seen in children and young adults. Due to its rarity, this tumor can be easily misdiagnosed as its classification, histogenesis and therapeutic management are still being discussed. We report the case of a 21 year old man, who presented at the Emergency Room for loss of consciousness.

[Primary colonic extranasal NK/T-cell lymphoma: about a case].

To better understand this cancer, we here report the case of a 43-year old patient diagnosed with localized and isolated primary colonic NK/T-cell lymphoma without associated enteropathy, treated wih 3 cycles of AspaMetDex with a poor response who died during treatment with a clinical picture of acute abdomen. Primary intestinal NK/T-cell lymphoma most commonly affects the young subject with poor prognosis. It is difficult to distinguish between intestinal NK/T-cell lymphoma and inflammatory or infectious intestinal disorders because of its non-specific clinical and endoscopic features.
