RESUMO
A woman in her 60s with a past medical history of recurrent Helicobacter pylori (H. pylori) presented for surgical consultation after a colonoscopy revealed a mass in the rectum. Preoperative biopsy revealed mucosal excrescence with no dysplasia or malignant changes. The final pathology showed a solid, submucosal rectal mass that was positive for SOX10 and S100 on immunohistochemistry, supporting our diagnosis of Schwannoma. This case emphasizes the importance of considering schwannomas in the differential diagnosis of patients presenting with a rectal mass no matter how rare it may be.
RESUMO
Compartment syndrome (CS) can be defined as an acutely painful condition that occurs due to increased pressure within a compartment, resulting in reduced blood flow and oxygen to nerves and muscles within the limb. It is considered a surgical emergency, and a delayed diagnosis may result in ischemia and eventual necrosis of the limb. The majority of cases in adults are associated with high-energy trauma, more specifically, long bone fractures of the lower limb, while supracondylar fractures of the humerus are highly associated with CS in pediatric patients. CS may also develop gradually as a result of prolonged and ongoing physical activity such as running. In this narrative review, we discuss the anatomy, pathophysiology, methods of diagnosis, and effective management of CS in adults and children.
RESUMO
Giant squamous cell carcinoma (GSCC) of the skin arising on the head presents a distinctive clinical challenge due to its rarity, aggressive behavior, and potential for disfigurement. A male in his 70s with a history of tobacco cigarette use presented to the emergency department with a painful, bleeding mass on the right parietal scalp. On admission, a brain CT revealed a fungating mass with no cortical breakthrough or osseous erosion, measuring 7.9 x 5.7 x 2.5 cm. An ultrasound-guided tissue biopsy was performed and revealed poorly differentiated squamous cell carcinoma. The patient was discharged home with instructions from oncology to continue with outpatient treatment. At this time, the prognosis is good if treatment is received.
RESUMO
A 72-year-old woman with a prior sigmoid resection for colon cancer underwent a right hemicolectomy after a colonoscopy revealed a mass in the hepatic flexure. A preoperative biopsy at colonoscopy showed tubulovillous dysplasia with high-grade neoplasm. The final specimen pathology revealed benign mucosal elements with mucin pools consistent with colitis cystica profunda (CCP). CCP is a benign lesion; no further treatment was necessary after resection. To our knowledge, this is the first reported case of CCP in the right colon, presenting atypically in the hepatic flexure. This case report brings to light the difficulty and importance of making an accurate diagnosis of CCP.
RESUMO
Ewing sarcoma is one of the most common primary bone tumors arising from neuroectodermal cells mainly presenting in the younger population. Instances of this highly malignant tumor manifesting outside of the bone and outside of the typical age range create an unfamiliar clinical scenario. In this report, we present a rare extraskeletal Ewing sarcoma in a 42-year-old woman with a subcutaneous soft tissue mass in the posterior chest displaying a positive EWSR1 gene rearrangement via fluorescence in situ hybridization. The patient is currently on a chemotherapy regimen showing favorable response to the tumor size despite additional complications. This overall presentation of Ewing sarcoma allows further understanding of the malignancy and fosters better care for future cases.
