Cytologic, histologic, and molecular features of pancreatic sarcomatoid undifferentiated carcinoma with heterologous osteosarcomatous transformation. Diagn Cytopathol 2023; 51:E164-E169. [PMID: 36762822 DOI: 10.1002/dc.25114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 01/13/2023] [Accepted: 01/30/2023] [Indexed: 02/11/2023]
Abstract
Fine-needle aspiration (FNA) is a minimally invasive and effective modality to diagnose pancreatic ductal adenocarcinoma. However, some histologic subtypes of ductal adenocarcinoma are rarely encountered and challenging to diagnose on FNA/small biopsies. To date, cytohistologic features of pancreatic sarcomatoid undifferentiated carcinoma with heterologous elements have not been thoroughly described. An 83-year-old man with lower back pain was found to have an incidental pancreatic neck mass. FNA biopsy of the mass showed rare markedly atypical, large, pleomorphic cells in a background of abundant calcifications/bone formation without areas of conventional adenocarcinoma. A diagnosis of "Malignant neoplasm with osteosarcomatous differentiation" was rendered on the FNA specimen. Subsequently, a Whipple resection revealed a 4.1 cm lobulated, calcified pancreatic mass. Microscopic examination showed a heavily calcified/ossified mass with adjacent areas of a highly cellular malignant spindle cell proliferation and admixed large, pleomorphic tumor cells; no background conventional adenocarcinoma was identified. Cytokeratin immunostains MNF116 and CK19 were positive in a large subset of the malignant spindle cells, and AE1.3/CAM5.2 showed patchy weak staining. Molecular testing revealed mutations in KRAS, TP53, BRCA2, NTRK3, EPHA2, MYD88, and CBL. No reportable fusions were detected. The final diagnosis was "Sarcomatoid undifferentiated carcinoma with heterologous elements (osteosarcomatous differentiation)." Definitive diagnosis of extremely rare subtypes of ductal adenocarcinoma is challenging on FNA biopsies. In this case, cytologic evaluation was helpful in making an early diagnosis of a malignant neoplasm with highly unusual features, prompting appropriate triage and early surgical resection of a sarcomatoid undifferentiated carcinoma with prominent osteosarcomatous differentiation.

Prognostic indicators for undifferentiated carcinoma with/without osteoclast-like giant cells of the pancreas. HPB (Oxford) 2022; 24:1757-1769. [PMID: 35780038 DOI: 10.1016/j.hpb.2022.05.1344] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 05/03/2022] [Accepted: 05/26/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Undifferentiated carcinoma of the pancreas (UPC) is a rare malignancy. There are no standardized guidelines for treatment. Current management has been extrapolated from smaller reviews. METHODS 858 patients with UPC were identified in the 2004-2017 NCDB. Kaplan-Meier method followed by Cox proportional-hazards regression examined independent prognostic factors associated with overall survival (OS). Logistic regression analyses were performed to determine independent predictors of surgical intervention and the status of surgical resection by histologic subtype. RESULTS Patients with osteoclast-like giant cells (OCLGC) had a longer median OS compared to those without (aHR 0.52: 95% CI 0.41-0.67). Of the non-OCLGC subtypes, pleomorphic large cell demonstrated the shortest median OS (2.4 months). Surgical resection was associated with improved survival in all histologies except for pleomorphic cell carcinoma. R0 resection and negative lymph nodes were independently associated with an improved OS. CONCLUSION This is the largest database review published to date on UCP. OCLGC histology is associated with an improved survival compared to those without OCLGC. Of the non-OCLGC subtypes, pleomorphic large cell is associated with the shortest overall survival. Surgical resection is associated with a significant survival advantage for all histologies except for pleomorphic cell carcinoma.

The Utility of Endoscopic-Ultrasonography-Guided Tissue Acquisition for Solid Pancreatic Lesions. Diagnostics (Basel) 2022; 12:diagnostics12030753.

Abstract
Endoscopic-ultrasonography-guided tissue acquisition (EUS-TA) has been widely performed for the definitive diagnosis of solid pancreatic lesions (SPLs). As the puncture needles, puncture techniques, and sample processing methods have improved, EUS-TA has shown higher diagnostic yields and safety. Recently, several therapeutic target genomic biomarkers have been clarified in pancreatic ductal carcinoma (PDAC). Although only a small proportion of patients with PDAC can benefit from precision medicine based on gene mutations at present, precision medicine will also be further developed for SPLs as more therapeutic target genomic biomarkers are identified. Advances in next-generation sequencing (NGS) techniques enable the examination of multiple genetic mutations in limited tissue samples. EUS-TA is also useful for NGS and will play a more important role in determining treatment strategies. In this review, we describe the utility of EUS-TA for SPLs.

Abstract
Undifferentiated carcinoma with osteoclast-like giant cell (UCOGC) is a ductal carcinoma variant with a recently reported more protracted survival and pathognomonic histology comprising two cell populations: the mononuclear tumoral cells and nontumoral multinucleated giant cells. It usually presents as a large heterogenic tumor with mixed solid-cystic components. The tumor develops from the ductal epithelium but the sequence of epithelial changes is often not identified due to the rapid tumoral growth and associated necrotic changes. We report a case of a 76-year-old patient diagnosed with cephalic UCOGC originating in the epithelium of the main pancreatic duct with endoluminal growth and foci of other ductal neoplasms (high-grade pancreatic intraepithelial neoplasia (PanIN) and conventional ductal carcinoma). The particularity of our case consists in the identification of the columnar epithelium conversion, through high-grade PanIN, into UCOGC specific malignant features, in a large size tumor - aspect usually reported in small tumors. Alongside our case we also present a brief literature review of cephalic UCOGC case reports and case series.

Abstract
A 75-year-old man visited our hospital for the examination of a tumor in the pancreas. Computed tomography showed an 85×85-mm low-density tumor in the pancreas. The tumor was pathologically diagnosed as poorly differentiated carcinoma by endoscopic ultrasound-guided fine-needle aspiration. Although we started chemotherapy, the patient died 84 days after the diagnosis. An autopsy demonstrated a ruptured anaplastic carcinoma with mucoepidermoid carcinoma of the pancreas. Anaplastic carcinoma with mucoepidermoid carcinoma is a very rare histologic subtype of pancreatic carcinoma, so pathological findings are important for predicting the patient's prognosis. Physicians should be aware of this rare but fatal disease.

Abstract
Pancreatic ductal adenocarcinoma (PDAC), an epithelial neoplasm derived from the pancreatic ductal tree, is the most common histologic type of pancreatic cancer and accounts for 85%-95% of all solid pancreatic tumors. As a highly lethal malignancy, it is the seventh leading cause of cancer death worldwide and is responsible for more than 300 000 deaths per year. PDAC is highly resistant to current therapies, affording patients a 5-year overall survival rate of only 7.2%. It is characterized histologically by its highly desmoplastic stroma embedding tubular and ductlike structures. On images, it typically manifests as a poorly defined hypoenhancing mass, causing ductal obstruction and vascular involvement. Little is known about the other histologic subtypes of PDAC, mainly because of their rarity and lack of specific patterns of disease manifestation. According to the World Health Organization, these variants include adenosquamous carcinoma, colloid carcinoma, hepatoid carcinoma, medullary carcinoma, signet ring cell carcinoma, undifferentiated carcinoma with osteoclast-like giant cells, and undifferentiated carcinoma. Depending on the subtype, they can confer a better or even worse prognosis than that of conventional PDAC. Thus, awareness of the existence and differentiation of these variants on the basis of imaging and histopathologic characteristics is crucial to guide clinical decision making for optimal treatment and patient management.

Abstract
Anaplastic carcinoma of the pancreas (ACP) is a rare and aggressive variant of pancreatic ductal adenocarcinoma (PDAC). Several studies have attempted to characterize this subtype through case series or single case reports; however, ACP remains underrecognized by cytopathologists in particular, and often lumped under the umbrella of classic PDAC. Here, we review the most up to date data that literature provides about ACP, to bring familiarity with this entity to the cytopathology practice, and to elucidate the role cytopathologists can play in recognizing and diagnosing this subtype on pancreatic aspiration biopsy, before surgical resection. We also describe a rare case of ACP, demonstrating signet ring cell features, that was diagnosed on fine needle aspiration of a pancreatic mass.
