RESUMO
Solitary fibrous tumor (SFT) is an uncommon mesenchymal tumor and is classified as an Intermediate (rarely metastasizing) fibroblastic/myofibroblastic tumor (WHO 2013). It occurs as slow growing masses at any location in deep soft tissue, abdomen/pelvis, pleura, the extremities and other sites. We present a case of a 60-year-old woman with a slow growing swelling of the right thigh. On magnetic resonance imaging, a large lobulated, heterogeneously enhancing septated lesion was noted. Wide excision of the lesion showed a well-circumscribed tumor with gray white and mucoid areas. Light microscopic examination showed a circumscribed, partially encapsulated tumor composed of hypercellular areas with intervening hypocellular, hyalinized areas were seen and tumor cells showed diffuse strong CD34 positivity. Based on histopathology and immunohistochemistry (IHC), a final diagnosis of SFT was offered. SFTs belong to a spectrum of neoplasms from benign to malignant which can occur at myriad sites in the body. IHC forms the basis for confirmatory diagnosis. To prevent mislabeling as sarcoma, a high degree of suspicion and radio-histological correlation is warranted to arrive at a conclusive diagnosis.
RESUMO
Adenomyomatosis of the gallbladder is a benign and degenerative condition of the gallbladder. It is an incidental finding in gall bladder specimens resected for chronic cholecystitis or cholelithiasis. It frequently occurs after 3rd or 4th decade of life and is often an incidental finding in cholecystectomy specimens resected for chronic cholecystitis or cholelithiasis. Patients with adenomyomatosis are usually asymptomatic it can be classified into three types: Segmental, fundal and diffuse types. The fundal variant is uncommon compared to the other two types. Here, in we present a case of a fundal variant of adenomyomatosis of the gall bladder in a 65-year-old male patient.
