Unveiling the Unlikely: Extraskeletal Ewing Sarcoma Masquerading as Gastrointestinal Bleeding

While Ewing sarcoma is traditionally a malignant tumor of bone, it may uncommonly present extra-skeletally, leading to an array of puzzling presentations depending on the tissue involved. Here, we describe the case of a 66-year-old man who presented to the primary care office for evaluation of intermittent melena. He ultimately underwent capsule endoscopy and developed a secondary small bowel obstruction, unveiling his neoplasm. The tumor was then resected and managed with surveillance only, and the patient remains without evidence of disease after four years of follow-up.

Rare Presentation of Primary Pleural Ewing Sarcoma With a Mass Extending Into the Right Ventricle: A Case Report

Primary pleural Ewing sarcoma is a rare type of Ewing sarcoma with only a few case reports identified in the literature. The condition is challenging to diagnose with deceiving symptoms and wide differential diagnosis. Diagnosis is confirmed with a combination of radiological and pathological assessment. Treatment is similar to other types of Ewing sarcoma with chemotherapy and surgery being the mainstay of treatment. We identify an unusual presentation of pleural Ewing sarcoma in a 31-year-old male with a mass extending into the right ventricular outlet causing rapid deterioration of the patient.

Primary Ewing's Sarcoma of the Penis: First Reported Case in the United Kingdom

Penile cancer is generally rare, and Squamous cell cancer of the penis is the most common histological type. Sarcoma of the penis has a low incidence, but they tend to grow faster than other penile cancers. One of the rarest types of penile sarcomas is Extra-Skeletal Ewing's Sarcoma (EES). The management of such cases can be challenging, and treatment guidelines do not exist for these rare cases. We present a rare case of EES that has developed in the penis of a young patient in the United Kingdom.

Ewing Sarcoma of the Lung: Imaging of a Rare Tumor

Primary pulmonary Ewing sarcoma is an extremely rare tumor of neuroectodermal tissue. In this article, we report on the case of a 45-year-old female who presented in the emergency department with shortness of breath and night fever. Radiologic findings suggested a massive pulmonary mass and a metastatic liver lesion. The diagnosis of Ewing sarcoma was established through a percutaneous biopsy of the lung mass and liver lesion. We highlight the importance of considering a broad differential diagnosis for a large pulmonary mass in order to lead to a prompt diagnosis and treatment.
