Introduction: Pleomorphic giant cell pancreatic cancer is a very rare and aggressive pancreatic neoplasm. A case of pleomorphic giant cell pancreatic cancer presenting as a cystic lesion and in association with a serous cystadenoma presents a unique case which has not been described before.
Case Presentation: A 44-year-old alcoholic man presented with abdominal pain, vomiting, and weight loss. Initially, imaging suspected a pancreatic pseudocyst measuring 4.2 cm. Endoscopic ultrasound- (EUS-) guided fine-needle aspiration revealed a serous cystadenoma. With conservative intervention only (fluid resuscitation, analgesia, and antiemetics) the patient improved and was discharged under close observation. Follow-up scan at four months revealed minimal change. Three months later, he was admitted acutely. Repeat scans demonstrated mild cyst enlargement with new liver lesions. Laparoscopic biopsy revealed pleomorphic giant cell carcinoma with the organ of origin the pancreas.
Conclusion: This unusual case highlights the challenges in managing pancreatic cystic lesions and emphasizes the importance of considering less common forms of pancreatic cystic masses when the findings are atypical for the presentation. Surgical excision in these cases over conservative steps may be the most appropriate management.

Feline injection-site sarcomas (FISSs) are malignant skin tumors of mesenchymal origin arising at local post-vaccination (or injection) sites. In recent years, a fluorescence imaging technique based on probes targeting αβ integrin has been effectively applied for the surgical complete resection of the tumor. In our study, we investigated the utility of a commercially available anti-α integrin polyclonal antibody for the histopathological evaluation of FISS's surgical excision margins.

The diagnosis of primary leiomyosarcoma (LMS) of bone is generally established based on integrative findings of morphologic features, immunohistochemical staining, and clinical and radiological findings. There are no specific genetic alterations that can be used to confirm the diagnosis of LMS in challenging diagnoses of bone sarcomas with myogenic differentiation. In this study, we assessed the utility of a DNA methylation-based classifier as an ancillary diagnostic tool for subclassifying bone sarcomas with myogenic differentiation.

Rationale: Primary sarcomatoid carcinoma of the trachea (PSCT) is a rare malignant tumor of the lower respiratory tract. Pathological types of tracheal sarcomatoid carcinoma (TSC)s include pleomorphic carcinomas, giant cell carcinomas, spindle cell carcinomas, pulmonoblastomas, and carcinosarcomas. At present, there are limited reports on PSCT, and pathologists lack sufficient knowledge about it.
