Synovial sarcoma is a rare mesenchymal tumor of soft tissue and has high metastatic potential. The most common sites of metastases are the lungs, lymph nodes and bones. The pancreatic location of a synovial sarcoma is very rare. Histological and immunohistochemical examinations are essential to confirm the diagnosis. We report the case of a 57-year-old patient treated for (SS) of pulmonary localization 2 years ago and who currently presents with pancreatic localization.

This review presents a study on the anatomical and histological features of the central nervous system in rose-ringed parakeets. The study involved nine healthy pairs of parakeets divided into three groups: Juvenile, Breeding Adults, and Non-Breeding Adults. Macroscopic and microscopic analyses were conducted on the brain, spinal cord, and optic lobes, along with measurements of body weight and dimensions. The results showed that adult parakeets during the non-breeding season exhibited the highest weights and dimensions in the body, brain, cerebrum, cerebellum, and eyes, while these parameters were lowest in juveniles. The study also highlighted the extensive optic tracts in parakeets, suggesting their high visual activity. Moreover, these findings provide major contribution into the central nervous system characteristics of rose-ringed parakeets and their developmental changes throughout different life stages. In addition, this study conducted to investigate the anatomical and histological features of the central nervous system in rose-ringed parakeets. The research involved nine pairs of healthy parakeets, categorized as Juvenile, Breeding Adults, and Non-Breeding Adults. The brain, spinal cord, and optic lobes were examined through macroscopic and microscopic analyses, while body weight and dimensions were recorded. The study found that adult parakeets during the non-breeding season exhibited the highest weights and dimensions in various anatomical structures including the body, brain, cerebrum, cerebellum, and eyes. Conversely, juveniles showed the lowest measurements. Additionally, the parakeets displayed extensive optic tracts, indicating their heightened visual activity.

Background: Hemorrhoids are a prevalent condition affecting the anal and rectal area, often resulting in symptoms such as bleeding, pain, and prolapse. While typically benign, they can coexist with other anorectal issues, including anal fissures and polyps. Rarely, neuroendocrine tumors may be discovered in patients with hemorrhoids, underscoring the necessity for thorough evaluation and histopathological examination to identify and address any significant underlying conditions. Case Presentation: This case describes a 39-year-old male presenting to the clinic on August 13, 2024. He reported a one-year history of rectal bleeding, pain, burning, and prolapse during defecation, along with occasional constipation. Physical examination revealed third-degree hemorrhoids, a chronic anal fissure, and an anal polyp. The primary diagnosis was third-degree hemorrhoids, with secondary diagnoses of chronic anal fissure, anal polyp, and constipation. The patient underwent elective surgical interventions, including stapler hemorrhoidopexy, fissurectomy, sphincterotomy, and excision of the anal polyp, all performed under general anesthesia without complications. Histopathological analysis of the excised hemorrhoidal tissue revealed a Grade 1 neuroendocrine tumor measuring 3 mm, with no evidence of malignancy elsewhere. Postoperative recovery was stable, with the patient reporting no significant complications during follow-up. Conclusion: This case illustrates the complexity of managing hemorrhoidal disease and its potential associations with other anorectal conditions, such as anal fissures and polyps. The identification of Grade 1 neuroendocrine tumors emphasizes the importance of thorough evaluation in patients presenting with rectal symptoms, even when benign conditions are suspected.
