However, difficult cases showing equivocal morphology have been reported in some organs. Herein, we report a case of primary hepatic neuroendocrine neoplasm (NEN) with ambiguous histopathological features admixed with conventional hepatocellular carcinoma (HCC). A 70-year-old man with untreated chronic hepatitis B underwent left medial sectionectomy because of two incidental liver masses. On pathological examination, one of the resected tumors had intermingling NEN and HCC components. The NEN component consisted of relatively uniform tumor cells proliferating in trabecular, cord-like, or solid patterns with peripheral nuclear palisading. The tumor cells were immunopositive for synaptophysin, chromogranin A, cluster of differentiation 56 (CD56), and focally hepatocyte paraffin 1. p53 showed wild-type expression. The Ki-67 labeling index was 27% at the hot spot. Eleven months after the surgery, he died of a cerebral hemorrhage without evidence of recurrent liver cancer. The intermediate degree of differentiation and the modest proliferative activity can challenge the distinction between NEC and NET G3. While the coexisting HCC indicates NEC rather than NET in a pathogenetic viewpoint, such ambiguous tumor may not be as aggressive as typical NECs.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":" ","pages":"62-68"},"PeriodicalIF":1.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142036288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The disease manifests itself clinically through irregular and painful blisters that rupture, resulting in erosion and ulceration areas. Histopathologically, the presence of an intraepithelial cleft located above the basal layer and acantholysis are observed. Standard treatment encompasses systemic and topical corticosteroids, with prednisolone being widely employed. Management consists of a remission induction phase and a maintenance phase. An early and accurate diagnosis is paramount to quickly initiate treatment, resulting in more favorable prognoses, as the choice of treatment and responses depend on the severity of the disease.

This study investigated the therapeutic effect of spinal cord stimulation (SCS) on patients with diabetic foot disease and a rat model of diabetic foot injury. SCS was applied to patients with diabetic foot disease, with clinical assessments performed before and after therapy. Blood levels of NGF, BDNF, and NT-3 were determined by ELISA. A rat model of diabetic foot injury was established to validate NT-3's role in SCS therapy. SCS therapy improved the condition of patients with diabetic ischemic foot disease and promoted wound healing in the rat model. NT-3 levels significantly increased after SCS therapy in both patients and rats. Recombinant NT-3 administration improved wound healing and re-vascularization in the rat model, while NT-3 neutralization abrogated SCS's therapeutic effect. SCS improves the condition of patients with diabetic ischemic foot disease by inducing NT-3 production. Both SCS and NT-3 supplementation show therapeutic potential for ameliorating diabetic foot disease.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":" ","pages":"43-52"},"PeriodicalIF":1.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11829938/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142644472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research has shown that corneal nerve dysfunction may play a role in certain pathologies of dry eye; however, the details remain unclear. To clarify the aberration in corneal nerves underlying sensory abnormalities, in addition to corneal impairment in dry eye, we examined the morphological alterations of nerve fibers in the corneas excised from guinea pigs with dry eye, where the lacrimal glands were surgically excised. Guinea pigs with dry eye exhibited reduced tear volume, increased spontaneous blink frequency, and corneal epithelial damage. Simultaneously, the subbasal nerve plexus in the cornea visualized using an anti-tubulin βIII antibody partially outgrew and became convoluted. The morphology of peptidergic nerves containing calcitonin gene-related peptide, which may function as a polymodal nociceptor, was also altered. These results indicate that guinea pigs with excised lacrimal glands can serve as useful tools for investigating the neuronal mechanisms underlying corneal pathology in dry eyes. Additionally, chronic tear deficiency may considerably alter nerve structure, including peptidergic nerves in the cornea, accompanied by epithelial damage and increased blink frequency.","PeriodicalId":18338,"journal":{"name":"Medical Molecular Morphology","volume":" ","pages":"34-42"},"PeriodicalIF":1.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142623548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory findings showed increases in AST, ALT, ALP, gamma-GT, CA19-9 and DUPAN-II. The patient then underwent an extended right hepatectomy. Histopathologically, the tumor was composed of an ASC component within an abundant fibrous stroma and a sarcomatoid carcinoma component. By immunohistochemistry, keratin 7 and keratin 19 were expressed by all tumor cells. Expression of keratin 5/6, p40 and p63 was restricted to the squamous component. The sarcomatoid component was immunoreactive for vimentin with no loss of INI1 expression. This component also showed a loss of membranous E-cadherin expression and a reduction of membranous β-catenin expression. Staining for desmin, myoglobin and HepPar1 was negative in any tumor cells.

Histopathological and immunohistochemical analyses confirmed the diagnosis of alpha-fetoprotein-producing neuroendocrine neoplasm that was further supported by genetic testing, which revealed FGFR2 and TP53 mutations commonly encountered in intrahepatic cholangiocarcinoma. Despite receiving various chemotherapeutic regimens, the patient exhibited a progressive disease. This case underscores the importance of accurate differential diagnosis from hepatocellular carcinoma and intrahepatic cholangiocarcinoma due to differences in treatment approaches and prognoses and highlights the necessity for increased awareness of AFP-producing primary hepatic neuroendocrine neoplasms among clinicians and pathologists. It emphasizes the significance of comprehensive histopathological evaluation, immunohistochemical profiling, and genetic analysis for precise diagnosis and tailored therapeutic strategies.
