Undifferentiated carcinoma of the pancreas is an aggressive but rare tumor for which several other terms have been used to describe its histological appearance. In addition, as osteoclast-like giant cells may accompany undifferentiated carcinoma of the pancreas, the WHO Classification distinguishes undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) from plain undifferentiated carcinoma since there are a few histopathological and clinical differences. UC-OGC was initially thought to be associated with worse prognosis compared to invasive ductal pancreatic adenocarcinoma, since it is often unresectable at diagnosis and tends to recur rapidly even if completely resected. When true UC-OGGs are carefully dissected out from other anaplastic carcinomas, it becomes, however, clear that UC-OGCs do have more indolent behavior, especially the pure UC-OGCs. This mini-review summarizes the current knowledge on UC-OGC.

Background: Carcinoma of the gallbladder (CaGB) is common in India and its prognosis depends primarily on the extent of the disease and histological type. We aim to study the role of guided fine needle aspiration cytology (FNAC) for diagnosis of CaGB and to evaluate the feasibility of applying world health organization (WHO) classification on fine needle aspiration (FNA) material to predict the outcome of the tumor. Materials and Methods: Retrospective cytomorphologic analysis was performed in all cases of CaGB diagnosed by ultrasound (US) guided FNAC over a period of 2 years. A specific subtype was assigned according to WHO classification based on characteristic cytologic features. These included papillary or acinar arrangement, intra and extracellular mucin, keratin, rosettes and columnar, signet ring, atypical squamous, small, clear, spindle and giant cells. Correlation with histopathology was performed when available. Results: A total of 541 aspirations with clinical or radiological suspicion of primary CaGB were studied. Of these, 54 aspirates were unsatisfactory. Fifty cases were negative for malignancy. Remaining 437 aspirates were positive for carcinoma. Histopathologic diagnosis was available in 32 cases. Adenocarcinoma was the most frequent diagnosis in 86.7% of cases. Mucinous, signet ring, adenosquamous, squamous, small cell, mixed adenoneuroendocrine and undifferentiated carcinoma including spindle and giant cell subtypes were diagnosed identifying specific features on FNAC. Correlation with histopathology was present in all, but one case giving rise to sensitivity of 96.8%. No post-FNA complications were recorded. Conclusions: US guided FNAC is a safe and effective method to diagnose CaGB. Although, rare, clinically and prognostically significant variants described in WHO classification can be detected on cytology.

Undifferentiated carcinoma of pancreas with osteoclastic giant cells is a rare tumor. The prognosis is slightly better than usual anaplastic carcinoma. It is said to have an epithelial origin. We present a case of 61-year-old female who presented with features of cholangitis and on evaluation found to have pancreatic mass. Pancreatic intraepithelial neoplasia was also present in our case, which is a feature less commonly noted in published literature.

Abstract Background Undifferentiated carcinoma with osteoclast-like giant cells (UCOGCs) is a rare and aggressive non endocrine pancreatic carcinoma characterized by the presence of osteoclastic giant cells mixed with mononuclear cell. Very few cases have been reported in the literature and the histogenesis is controversial as, at the time of diagnosis, the tumor is often of advanced size and stage and it is difficult to pathologically observe its relationship with the pancreatic duct. Case presentation We present a case of 65-year-old male patient presenting with abdominal pain, nausea, and weight loss, which was treated with surgical resection. Histological examination revealed an undifferentiated pancreatic carcinoma with osteoclast-like giant cells. The patient underwent to a routine pylorus preserving pancreatoduodenectomy. Actually, the patient was in good performance status and disease-free five months. Conclusions Based on the present case and limited previous data, further researches preferably with large cohorts are necessary to clarify the pathogenesis of the neoplasm. However, as show in this case, histopathological and immunohistochemically studies are the gold standard for the diagnosis of UCPOGC. Investigation of the genomic alterations in UPOGCs could help to explain the histologic diversity of variant tumor and could provide a genetic basis for prognosis and treatment.

Carcinosarcoma is a rare tumor composed of variable proportions of carcinomatous and sarcomatous elements and comprises less than one percent of all gallbladder malignancies. In most reported cases of carcinosarcoma of gallbladder, the epithelial component is adenocarcinoma. The mesenchymal component varies from homogenous sarcoma to more heterotopic elements like malignant bone, cartilage, and other mesenchymal tissues. We report a rare case of carcinosarcoma of the gallbladder in an 83-year-old male, with the carcinomatous component represented by undifferentiated carcinoma (spindle and giant cell type with osteoclastic giant cells) and the mesenchymal component seen as foci of chondrosarcoma.
