Huang X, Guo X, Yu Y. Case report and literature analysis: pancreatic hepatoid carcinoma with multiple lymph node metastases progressing to liver metastasis after pancreaticoduodenectomy. Front Oncol 2024; 14:1335647. [PMID: 38737909 PMCID: PMC11082267 DOI: 10.3389/fonc.2024.1335647] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 04/05/2024] [Indexed: 05/14/2024] Open
Abstract
Hepatoid carcinoma is an extrahepatic primary tumor displaying characteristics reminiscent of hepatocellular carcinoma differentiation, which is found in various organs, such as the stomach, ovaries, gallbladder, and pancreas. Reports of pancreatic hepatoid carcinoma remain scarce. Consequently, understanding of this disease remains a priority, with no established consensus on its diagnosis and management. Here, we reported the case of a 45-year-old woman diagnosed with hepatoid carcinoma located in the pancreatic head, accompanied by multiple lymph node metastases. Following pancreaticoduodenectomy, the patient developed liver metastases within 3 months. Subsequently, she underwent adjuvant therapy consisting of Teysuno and Durvalumab following microwave ablation for the liver metastases. Remarkably, the patient has survived for one year without significant disease progression. This case underscores the potential efficacy of immunotherapy as a promising treatment option for pancreatic hepatoid carcinoma. Further research and clinical trials are warranted to explore the optimal management strategies for this rare and challenging malignancy.

Mixed pancreatic hepatoid carcinoma: A surgical case report and literature review. Int J Surg Case Rep 2021; 83:105951. [PMID: 33971555 PMCID: PMC8129926 DOI: 10.1016/j.ijscr.2021.105951] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2021] [Revised: 04/23/2021] [Accepted: 04/24/2021] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Hepatoid carcinoma (HC) is a rare type of malignant tumor that shared similar features of morphology and immunohistochemistry with hepatocellular carcinoma (HCC). Pancreatic HC exists as either pure or mixed type. Mixed pancreatic HC is extremely rare, with only a few cases reported in the literature to date. Because of the rarity of mixed pancreatic HC, its clinical features including incidence, characteristics, and prognosis remain unclear. We herein report a case of a 49-year-old man who was diagnosed with mixed pancreatic HC with neuroendocrine differentiation and was treated with pancreaticoduodenectomy and adjuvant chemotherapy. We also review the existing case reports in literature. PRESENTATION A 49-year-old man was admitted to our hospital after a chronic abdominal pain in the upper right quadrant. Abdominal ultrasound revealed only one low-density retroperitoneal mass measured at 20 × 48mm in size in the pancreatic-duodenal junction, whereas contrast-enhanced computed tomography (CT) revealed three lymphatic neoplasms measured at 28 × 22 × 30 mm, 27 × 33 × 38 mm and 22 × 35 × 48 mm in size in the retroperitoneal pancreatic-duodenal junction. Ultrasound-guided tumor biopsy was performed. Pathological reading of tumor biopsy suspected of Paraganglioma/pheochromocytoma. Laparotomic retroperitoneal tumoral resection and lymphadenectomy was then performed. Histological reading was lymphatic metastasis of primary pancreatic hepatocellular carcinoma with neuroendocrine differentiation, which were immunohistochemically positive for CKAE1/AE3, Hepatocyte paraffin 1, Chromogranin. After three weeks of the first surgery, the patient was assigned with Positron Emission Tomography - Computed Tomography (PET-CT) before adjuvant chemotherapy, revealing a low-density high-metabolism mass, 26 × 28 mm in size within the parenchyma of pancreatic head. Laparotomic pancreaticoduodenectomy and standard lymphadenectomy was performed to resect one mass, which revealed the same immunohistology features with the first mass. The patient was followed up with FOLFIRINOX protocol, and after 12 cycles, there was no evidence of postoperative recurrence. DISCUSSION There are few reported cases describing pancreatic hepatoid carcinoma, especially mixed form with other histological associated component. Neuroendocrine differentiation is the majority associated component with 62.5% of all cases of mixed - type form. CONCLUSION Primary pancreatic hepatocellular carcinoma with neuroendocrine differentiation was rare, biopsy and immunohistochemistry appeared with high diagnostic value in this case. The prognosis of pancreatic HC depends on the extent and tumor eradication, and in this case we recorded no postoperative complications and no recurrence in the 6-month follow-up period.

Abstract
The nomenclature and classification of pancreatic neuroendocrine neoplasms has evolved in the last 15 years based on the advances in knowledge of the genomics, clinical behaviour and response to therapies. The current 2019 World Health Organization classification of pancreatic neuroendocrine neoplasms categorises them into three groups; pancreatic neuroendocrine tumours (PanNETs)(grade 1 grade 2, grade 3), pancreatic neuroendocrine carcinomas and mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) based on the mitotic rate, Ki-67 index, morphological differentiation and/or co-existing tissue subtype. PanNETs are also classified into non-functional NET, insulinoma, gastrinoma, VIPoma, glucagonoma, somatostatinoma, ACTH-producing NET and serotonin producing NET based on hormone production and clinical manifestations. A portion of the cases were associated with genetic syndromes such as multiple neuroendocrine neoplasia 1 (MEN 1), neurofibromatosis and Von Hippel-Lindau syndrome. In view of the distinctive pathology and clinical behaviour of PanNENs, the current 8th AJCC/UICC staging system has separated prognostic staging grouping for PanNETs from the pancreatic neuroendocrine carcinomas or MiNENs. Pancreatic neuroendocrine carcinomas and MiNENs are staged according to the prognostic stage grouping for exocrine pancreatic carcinoma. The new stage grouping of PanNETs was validated to have survival curves separated between different prognostic groups. This refined histological and staging would lead to appropriate selections of treatment strategies for the patients with pancreatic neuroendocrine neoplasms.

Abstract
BACKGROUND Hepatoid carcinoma (HC) is an extremely rare neoplasm that is morphologically similar to hepatocellular carcinoma. HC has been described in various organs; however, HC of the pancreas is extremely rare. To our knowledge, only 38 cases have been reported. We present a case of HC of the pancreas in a 36-year-old male patient.
CASE SUMMARY A 36-year-old cachexic man with no significant past medical history was transferred to our hospital with a history of painless jaundice, elevated blood glucose and significant weight loss. Lab tests showed elevated serum transaminases, bilirubin and alpha-fetoprotein levels. Magnetic resonance imaging of the upper abdomen showed a diffusely enlarged pancreas, appearing “sausage-shaped”. Magnetic resonance cholangiopancreatography showed upstream ductal dilation secondary to stricture of the main pancreatic duct and the common bile duct, which were not visible. Immunohistochemistry of biopsied tissue from a percutaneous pancreatic biopsy showed tumor cell positivity for HepPar1, polyclonal carcinoembryonic antigen and CK19, suggestive of HC of the pancreas. The characteristics of 39 patients with HC of the pancreas were reviewed.
CONCLUSION HC of the pancreas is more prevalent in males, and patients have a median age of 57 years. It is most commonly asymptomatic or presents as abdominal back pain, and the pancreatic tail is the most common location. At the time of diagnosis, liver metastasis is often present.

Abstract
Primary pancreatic hepatoid carcinoma (PHC) is very rare. Here, we reported 3 such cases with review of additional 31 cases in the literature. Our 3 patients were male (83, 72, and 54 years old, respectively). Serum α-fetoprotein (AFP) was elevated in 1 patient (case 3, 8338 ng/mL) and not measured in the other two. The PHC in patient 1 (pathological stage pT2N0M0) and patient 2 (pT3N0M0) showed pure hepatocellular carcinoma (HCC)-like morphology, whereas in case 3 it was a PHC with true glandular differentiation (pT4N0M0). The diagnosis of PHC was confirmed with positive immunohistochemical staining in the tumor cells for AFP (2/3), Hep Par 1 (3/3), glypican-3 (2/3), arginase-1 (2/3), and Sal-like protein 4 (1/3). CD10 and polyclonal carcinoembryonic antigen stains show focal canalicular pattern in 2/3 tumors. Patient 1 did not receive further treatment after resection and was alive with no evidence of disease at 107 months. Patient 2 died of postoperative complications, whereas patient 3 received postsurgical chemoradiation and died of disease at 29 months. Our findings and literature review indicate that PHCs can be divided into 4 histological subtypes: with pure HCC-like morphology (n = 22), with neuroendocrine differentiation (n = 8), with true glandular differentiation (n = 3), and with acinar cell differentiation (n = 1). On univariate analysis, pure HCC-like morphology was associated with better disease-specific survival (DSS; P = .04), whereas lymph node and distant metastases were associated with worse DSS ( P = .002 for both). Age, gender, presenting symptoms, serum AFP level, and T stage were not associated with DSS. On multivariate analysis, none of these parameters was significantly associated with DSS.

Abstract
Fewer than 25 cases of hepatoid carcinoma of the pancreas have been reported in the literature. We present a case in a 61-year-old male with a remote history of Hodgkin's lymphoma and gastric neuroendocrine cell hyperplasia. On surveillance endoscopic ultrasound, an 8 × 5 mm cystic lesion was seen in the tail of the pancreas. MRI showed a focal pancreatic duct cut-off with mild ductal dilation. Fine needle aspiration was performed, which was concerning for acinar cell carcinoma. The patient underwent distal pancreatectomy and recovered uneventfully. Final pathology demonstrated a 1.3-cm hepatoid carcinoma of the pancreas, with a final clinicopathological stage of T1N0M0. Next-generation nucleic acid sequencing of the tumor did not suggest a viable adjuvant chemotherapeutic agent, and no adjuvant therapy was administered. The patient has no evidence of disease 6 months following resection. A further characterization and description of the outcomes of these rare tumors is warranted to help guide providers and counsel patients.

Abstract
A 59-year-old man was admitted to our hospital for treatment of a 45 mm pancreatic mass found during a medical examination. Endoscopic ultrasound-guided fine-needle aspiration cytology showed polygonal cells with pseudopapillary structures. The tumor cells were positive for nuclear/cytoplasmic β-catenin and CD10, and negative for chromogranin A. After a tentative diagnosis of a solid pseudopapillary neoplasm, middle pancreatectomy was performed. Histologically, polygonal cells with abundant eosinophilic cytoplasm formed in the trabeculae and were immunohistochemically positive for HepPar1 and protein induced by vitamin K absence or antagonist-II. The tumor was finally diagnosed to be pancreatic hepatoid carcinoma. No recurrence occurred for 12 months, even without adjuvant chemotherapy.

Abstract
OBJECTIVE The term hepatoid adenocarcinoma (HAC) of the stomach was introduced three decades ago with the observation of high serum α-fetoprotein (AFP) levels in some gastric adenocarcinoma patients. This very rare gastric cancer patient subgroup is likely frequently misdiagnosed. MATERIAL Two patients who were recently diagnosed with HAC of the stomach at our institution are presented. We also performed a structured literature search and reviewed pertinent articles to provide knowledge to improve the proper identification, diagnosis and management of patients with gastric HAC. RESULTS HAC is a rare subgroup of gastric carcinoma with poor prognosis. Clinical management of this population may be challenging. The scientific literature is largely based on very small patient series or case reports, and the evidence for proper decision making and management is considered weak. CONCLUSION All physicians involved in the diagnosis and treatment of patients with gastric cancer should pay attention to this rare subgroup to improve identification.

Abstract
Pancreatic hepatoid carcinoma (HC) is an extremely uncommon neoplasm of pancreas that resembles hepatocellular carcinoma (HCC). We report a case of incidentally detected pancreatic HC combined with a serous microcystic cystadenoma, in a 47-year-old man, while he was being evaluated for renal calculi. Contrast enhanced computed tomography (CECT) of abdomen revealed a lesion with mild heterogeneous enhancement in the tail of pancreas and another proximal lesion having moderate enhancement, and a calculus in the neck of gallbladder. Serum chromogranin, carcinoembryonic antigen (CEA) and CA 19-9 levels were within normal limits. He underwent laparoscopic distal pancreatectomy with splenectomy and cholecystectomy. Pathologically the distal tumor was encapsulated and characterized by eosinophilic cytoplasm, vesicular nucleus with prominent nucleolus and intranuclear eosinophilic inclusions. The cells were arranged in trabecular pattern separated by sinusoids. Canalicular and intercellular bile plugs were seen. On immunohistochemistry tumor cells were positive for hepatocyte specific antigen and weakly positive for alpha fetoprotein (AFP). The proximal tumor showed features of serous microcystic adenoma. Based on these findings, the case was diagnosed as hepatoid tumor of pancreas combined with serous microcystic cystadenoma. Post operative AFP was 1.75 IU/mL. The patient is on follow up for the last eight months and there is no evidence of recurrence.

Abstract
We report a case of tumour in the head of the pancreas observed in a 57-year-old man with a history of worsening jaundice and elevated alpha-fetoprotein (AFP) serum level, who underwent Whipple pancreatoduodenectomy. Histologically, the tumour was predominantly composed of solid sheets of large eosinophilic cells with a prominent lymphoid infiltration without association neither with DNA microsatellite instability nor Epstein-Barr virus infection. The tumour was diffusely and strongly positive for hepatocyte paraffin-1 (Hep Par-1) and glypican-3 leading to the diagnosis of hepatoid carcinoma. Strong cytoplasmic staining for AFP was focally observed. Moreover, tumour cells showed countless cytoplasmic eosinophilic globules immunoreactive for the stress protein p62. A primary hepatocellular carcinoma of the liver was ruled out by careful clinical analysis. Hepatoid carcinoma is an extremely rare pancreatic neoplasm, and here, we describe the first case of such variant associated with lymphoid stroma. The characteristic histologic features and the immunophenotypic profile help in distinguishing this carcinoma from other pancreatic tumours, notably from medullary carcinoma.

Abstract
Background Alpha-fetoprotein (AFP)-producing pancreatic neuroendocrine tumors (pNETs) are rare, and the few reported cases usually coexisted with other malignant components such as adenocarcinoma or hepatoid carcinoma. We present here the first case of pure AFP-producing pNET. Case presentation A 56-year-old male patient underwent resection of the pancreatic tail and body because of elevated serum AFP levels and pancreatic mass. Microscopy showed that the tumor tissue consisted of large and small solid nests of polygonal cells. The tumor cells were positive for chromogranin A, synaptophysin, CD99, cytokeratin 19, pan-cytokeratin and β-catenin, and also showed diffuse immunoreactivity for AFP and human chorionic gonadotrophin. The mitotic rate was nearly 30 per 10 high-power fields and the Ki-67 index was nearly 25%. The histopathologic findings supported the diagnosis of an AFP-producing pNET. Other malignant components were not found. Serum AFP levels decreased to near-normal after operation and gradually increased to >1000 ng/ml at 5 months post-surgery. Recurrence and hepatic metastases were revealed by computed tomography. The patient died 21 months after surgery. Conclusion This was the first case of pure AFP-producing pNET to be reported in the English literature. Serum AFP levels may provide useful information for monitoring the therapeutic effectiveness, early recurrence or metastases.

Pancreatic endocrine tumours are rare in occurrence. They may present with a baffling range of symptoms which pose a diagnostic dilemma. Two cases of pancreatic insulinoma are presented herewith. Both presented with neuro-psychiatric complaints and were treated symptomatically for depression, anxiety, seizures etc. The diagnosis in these patients was missed for years. Insulinoma being a great diagnostic challenge, requires reasonably high clinical suspicion, accurate biochemical diagnosis and radiological localization to avoid extensive surgery. The aim is to highlight the occurrence of this rare tumour at a tertiary care hospital.

Abstract
Primary pancreatic hepatoid carcinoma (PHC) is extremely rare, resembling hepatocellular carcinoma (HCC) in terms of morphology and immunohistochemical features. Hepatoid carcinoma can present in other organs, most noticeably in the stomach. PHC is present in two forms either a pure form like HCC or admixed with other histologic tumor components characteristic of the underlying primary site (endocrine tumors, ductal, or acinar adenocarcinomas). Here, we report a 69-year-old male patient with distal pancreatic mass incidentally found during a CT scan workup for a pulmonary nodule suspicious for metastatic prostate adenocarcinoma. We described the clinical, cytological, and histological finding and conducted a literature review.

Abstract
Key Clinical Message We present a case of hepatocellular carcinoma located within the pancreas. These tumors occur in the body and tail of the pancreas, with a male predominance, and at a younger age. Tumors with pure hepatocellular histopathology have better survival and recurrence rates and should be offered surgical therapy if possible.

Abstract
A 79-year-old Japanese woman was admitted to our hospital for treatment of a pancreatic tumor measuring approximately 7 × 5 cm. The tumor had invaded the left adrenal gland and gastric wall and had penetrated into the gastric cavity. Surgical resection was performed. The tumor was composed of a brown to whitish solid area and a zone of hemorrhage, necrosis, and cystic degeneration resembling the gross features of solid pseudopapillary tumor (SPT). Histologically, the tumor showed a heterogeneous growth pattern with a combination of seat-like, trabecular, papillary and hemorrhagic-necrotic areas in various proportions. The differential diagnoses first considered were acinar cell carcinoma, neuroendocrine carcinoma and SPT with malignant transformation. Immunohistochemistry showed tumor cells were negative for pancreatic exocrine enzymes and endocrine markers. Tumor cells diffusely expressed cytokeratin 19, alpha-fetoprotein, carcinoembryonic antigen and glypican-3, but lacked vimentin or β-catenin expression. Small proportions of tumor cells expressed hepatocyte paraffin-1. Although typical morphological features of well-differentiated hepatocellular carcinoma (HCC) were not distinctly apparent, the tumor morphology partly resembled poorly differentiated HCC. Given these findings and considerations, the tumor was finally diagnosed as poorly differentiated hepatoid carcinoma of the pancreas.

Abstract
Hepatoid carcinomas are tumors that display, at least focally, cytologic and/or architectural features of hepatocellular carcinoma. They have been described in several organs, most notably in the stomach and ovary. We report a case of hepatoid carcinoma of the pancreas that developed in a 41-year-old woman in association with a pancreatic endocrine carcinoma. The fine needle aspiration material was characterized by the presence of monotonous, small-to-medium sized tumor cells with round nuclei and finely granular chromatin, intermixed with more atypical tumor cells displaying larger nuclei with coarse clumped chromatin, prominent nucleoli, and moderate amounts of foamy cytoplasm. The excised specimen displayed a poorly differentiated pancreatic endocrine carcinoma associated with well-defined islands of larger tumor cells growing in a perisinusoidal pattern which, based on their immunohistochemical profile and the demonstration of bile, proved to represent a hepatoid component. This case and prior examples in the literature suggest that hepatoid carcinomas of the pancreas appear to be a heterogeneous group of tumors (pure or associated with another histologic component) that are often associated with early liver metastasis and a short survival, although those arising as a component of endocrine tumors seem to fare slightly better. Hepatoid carcinoma of the pancreas should be included in the differential diagnosis of pancreatic tumors composed of large eosinophilic cells.

Abstract
BACKGROUND Malignant insulinoma occurs in a few patients with insulinoma. Due to the small sample of patients, there are little data regarding their clinical manifestation as well as the preferred treatment modalities. The aims of the current study were to summarize the National Institutes of Health experience during the last two decades and to conduct a critical review of the current literature. METHODS The authors identified 10 patients with metastatic insulinoma. RESULTS The patients presented with four patterns of clinical behavior. First, four patients presented with lymph node metastasis and, after surgical excision, maintained a prolonged tumor-free survival. Second, four patients presented with metastatic disease to the liver, which appeared years after the initial diagnosis and presumed curative surgery. Third, one patient presented with a large alpha-fetoprotein-secreting liver mass. Finally, 9 of the 10 patients had a prolonged survival. Various treatment modalities were used to control hypoglycemia. Short-term benefits were most often achieved with embolization and diazoxide. Less successful modalities included radiofrequency ablation, radical debulking surgery, verapamil therapy, octreotide therapy, and chemotherapy. CONCLUSIONS The current study, as well as others, suggested that metastatic insulinoma may have a variable natural history. After the initial surgical resection, the biology of the tumor, rather than any treatment modality, was most likely the major determinant of long-term survival.

Abstract
Background Hepatoid carcinoma of the pancreas is extremely rare. This article tries to summarize the clinical features and outcomes of pancreatic hepatoid carcinoma. Methods The data pool for analysis includes the case we encountered with hepatoid carcinoma of the pancreas and the reported cases in the literature. Results Twenty-three cases of hepatoid carcinoma of the pancreas were analyzed. This tumor occurred more frequently in male than in female patients (69.6 vs. 30.4 %). Tumor sizes range from 0.5 to 11.0 cm with median of 6.0 cm. The most common symptom was epigastric pain (36.4 %). When the tumor locates at pancreatic head, nausea/vomiting (62.5 %) is more common, followed by jaundice and epigastric pain (50.0 %). For those at pancreatic body-tail, 42.9 % of the patients presented no symptom. Alpha-fetoprotein (AFP) was abnormally elevated in 60 % of the cases. Hepatoid carcinoma in the pancreas could be either pure form or mixed form with other malignancy (40.9 %), with the most common coexisted pathology of malignant neuroendocrine tumor (22.7 %). Metastasis occurred in 36.4 % of the cases at the diagnosis of this tumor, including liver metastasis in 31.8 % and lymph node metastasis in 21.1 %. The overall 1-year survival rate was 71.1 % and 5-year 40.4 %, with a median of 13.0 months. Unresectability, hepatic, and lymph node metastases are associated with negative impact on survival outcome. Conclusions Elevation of serum AFP may be a clue leading to the diagnosis of pancreatic hepatoid carcinoma. This tumor could be mixed form with other malignancy. Surgical resection should be the treatment of choice whenever possible.

Abstract
A biomic approach by integrating three independent methods, DNA microarray, proteomics and bioinformatics, is used to study the differentiation of human myeloid leukemia cell line HL-60 into macrophages when induced by 12-O-tetradecanoyl-phorbol-13-acetate (TPA). Analysis of gene expression changes at the RNA level using cDNA against an array of 6033 human genes showed that 5950 (98.6%) of the genes were expressed in the HL-60 cells. A total of 624 genes (10.5%) were found to be regulated during HL-60 cell differentiation. Most of these genes have not been previously associated with HL-60 cells and include genes encoded for secreted proteins as well as genes involved in cell adhesion, signaling transduction, and metabolism. Protein analysis using two-dimensional gel electrophoresis showed a total of 682 distinct protein spots; 136 spots (19.9%) exhibited quantitative changes between HL-60 control and macrophages. These differentially expressed proteins were identified by mass spectrometry. We developed a bioinformatics program, the Bulk Gene Search System (BGSS, http://www.sinica.edu.tw:8900/perl/genequery.pl) to search for the functions of genes and proteins identified by cDNA microarrays and proteomics. The identified regulated proteins and genes were classified into seven groups according to subcellular locations and functions. This powerful holistic biomic approach using cDNA microarray, proteomics coupled to bioinformatics can provide in-depth information on the impact and importance of the regulated genes and proteins for HL-60 differentiation.
