Telomerase reverse transcriptase ( TERT ) promoter mutations are frequently observed in hepatocellular carcinoma (HCC); however, the impact of (TPMs) on clinical features and morphological patterns HCC remains unresolved. Using DNA extracted from 97 HCCs, correlations between TPM status both immunohistochemically‐based subgroups were evaluated. Morphological tumor semi‐quantitatively analyzed using hematoxylin eosin‐stained slides whole cross‐sectional area. The percentages area occupied by...
Multistep hepatocarcinogenesis progresses from dysplastic nodules to early hepatocellular carcinoma ( eHCC ) and advanced HCC . The aim of the present study was investigate detailed histopathological features We investigated 66 small vaguely nodular lesions resected 40 patients. degree cellular structural atypia stromal invasion were assessed. immunohistochemical expression ‐related markers adenylate cyclase‐associated protein 2 CAP 2), heat shock 70 HSP 70), Bmi‐1, CD 34 h‐caldesmon...
The clinicopathological characteristics of steatosis in hepatocellular carcinoma (HCC) remain unclear. Here, we elucidate the features macrovesicular (MaS) and microvesicular (MiS) HCC their relationships with background liver steatosis. A total 165 lesions were classified as MaS‐HCC, MiS‐HCC, or conventional (cHCC) according to cutoff value 30% MaS MiS tumor cells. We analyzed differences among these groups. MaS‐HCC had less portal vein invasion, a higher proportion intratumoral fibrosis,...
Cardiac metastasis is relatively common in malignant neoplasms, such as lung cancers, breast melanomas, lymphomas, and leukemias. In contrast, cardiac of uterine cervical cancer, solitary to the heart, tumors inducing severe thrombocytopenia are rare.The present patient was a 52-year-old female who diagnosed with tumor prior cancer presented thrombocytopenia. Our case had two remarkable aspects: 1) successful treatment under condition association presence tumor, survival without recurrence...
A 75-year-old male presented with progressive lower abdominal discomfort. CT scan demonstrated hypertrophy of the intestinal wall, small bowel dilatation, and masses in descending colon. Biopsy specimens jejunum colon revealed widespread distribution medium-sized atypical lymphocytes an immunophenotype, positivity for CD3, CD8, CD56, TAI-1, granzyme B TCRβ, but negativity CD4, CD5, CD20, CD30 EBER-ISH. Type II enteropathy-associated T cell lymphoma (EATL; Lugano, stage IIE) was diagnosed....
Both disseminated cryptococcal infection and tuberculosis occur in hosts with impaired cell-mediated immunity, but there have been few reports about the concurrent infections patients without human immunodeficiency virus infection. A 64-year-old man, who had taking corticosteroids for interstitial pneumonia, was diagnosed While patient receiving anticryptococcal therapy, pulmonary also emerged. The developed acute exacerbation of pneumonia passed away. Based on patient’s clinical course,...
Invasive aspergillosis is a life-threatening opportunistic infection that occurs most often in immunocompromised patients, especially those with either hematological malignancies treated chemotherapy or organ transplant recipients. Here, we report 2 cases of disseminated invasive myocarditis proven pathologically by autopsy. These occurred patients: the first patient received for acute myeloid leukemia myelodysplasia-related changes (AML-MRC); second methotrexate therapy rheumatoid arthritis...
Hemangiopericytoma (HPC) is a highly vascularized mesenchymal tumor known for its high rates of recurrence and metastasis. The extent removal to be the most trustful prognostic factor. Skull base HPCs are challenging treat because difficulty surgical approach proximity vital vascular neuronal structures. We successfully treated case HPC at ventral foramen magnum through gross via far-lateral transcondylar approach.A 38-year-old male complained neck pain bilateral paresthesia his shoulders 2...
Retroperitoneal leiomyosarcoma (RPLMS) is rare and usually presents as a large abdominal mass with poor clinical symptoms. Radiological findings of an RPLMS arising in the pelvis woman resemble those adnexal tumors. Herein, we present case mimicking tumor which was differentiated from having ovarian origin right vein passing through but there no direct vascular connection tumor. Therefore, it important to identify distinguish between these
症例は66歳,男性.中咽頭癌(cT1N0M0,cStage I)のスクリーニング検査で胸部中部食道に1型,2cmの食道扁平上皮癌(cT2N1M0,cStage II)と,肝S4,5,8にわたる8cmの腫瘍を発見.手術侵襲度を考慮して,一期目に経口的中咽頭部分切除術,二期目に胸腔鏡下胸部食道切除亜全摘術と一時的頸部食道瘻造設術,三期目に腹腔鏡下肝中央二区域切除術,用手補助腹腔鏡下胃管再建術を行う方針とした.二期目では食道口側を胸部上部食道レベルで切離し一時的食道瘻を造設,噴門側は胸部下部食道レベルで仮切離し盲端とした.二期目から4週後の三期目では腹腔鏡下肝中央二区域切除術に続き用手補助腹腔鏡下胃管再建術を開始,食道盲端部が縦隔内で高度に癒着していたため開腹手術への移行を要したが,三期分割切除にすることで一連の手術治療を完遂した.ただし,鏡視下で手術を完遂するためには,インターバル期間の再考や食道切離端処理の工夫が必要と考えられた.
