A Suspicious Hilar Mass Revealing an Uncommon Diagnosis of Pulmonary Actinomycosis in an Immunocompromised Young Female Patient: A Case Report and Literature Review.

 Actinomycosis is a chronic inflammatory infectious disease that can affect various organ systems. Pulmonary actinomycosis is an exceptionally uncommon clinical occurrence that yet deserves special attention, as it closely mimics a broad spectrum of infectious and neoplastic lung pathologies. The non-specific nature of its clinical features and radiological appearances makes early diagnosis quite challenging.

Thoracic Spinal Cord Compression Secondary to Metastatic Papillary Thyroid Carcinoma: An Unusual Oncological Phenomenon.

Hematogenous spread is fairly an unusual feature for papillary thyroid carcinoma (PTC) in comparison to follicular thyroid carcinoma (FTC). Thoracic spinal metastasis with complicating cord compression is an even rarer manifestation of PTC that was reported in a limited number of cases in the literature. Herein we present a 65-year-old female with a history of PTC on current radiotherapy, status post attempted surgery due to significant tumor burden and intraoperative bleeding, presented with a one-week history of rapidly progressive bilateral lower extremities weakness.

Isolated Enteric Myeloid Sarcoma as a Rare Etiology of Small Bowel Obstruction in a Young Female Patient.

Myeloid sarcoma (MS) is an extra-medullary solid tumor consisting of myeloid blasts or immature myeloid cells. MS is usually associated with acute myeloid leukemia (AML) and other myeloproliferative neoplasms or myelodysplastic disorders. Isolated MS is a rare clinical entity, and the small bowel is a rare phenomenon for the occurrence of MS.

Multisystemic Sarcoidosis Presenting with Widespread Vertebral Osseous and Visceral Lesions Masquerading as Metastatic Disease: A Case Report and Literature Review.

BACKGROUND Sarcoidosis is a systemic granulomatous disease which predominantly affects the lungs, skin, and lymph nodes. Vertebral sarcoidosis is a rare entity. The clinical presentation of sarcoidosis with diffuse vertebral osseous and visceral lesions, simulating a disseminated metastatic cancer, is extremely unusual and has been reported only in a handful of cases in the current literature.

Posterior reversible encephalopathy syndrome in a patient with Richter's syndrome on combination DA-R-EPOCH chemotherapy regimen: a case report.

Background: Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiologic entity characterized by headaches, altered mental status, seizures, visual loss, and a characteristic imaging pattern in brain magnetic resonance images. The exact etiology and pathogenesis of this condition are not yet fully elucidated.

Case Presentation: A 72-year-old White man presented with 2 weeks of low-grade fever and chills, night sweats, fatigue, dysphagia, and new-onset rapidly increasing cervical lymphadenopathy.
