Flow Cytometry‐Guided Diagnosis of Cortical T‐Lymphoblastic Lymphoma Presenting With a Massive Mediastinal Mass and Borderline Bone Marrow Involvement

Journal of Clinical Laboratory Analysis, EarlyView.
ABSTRACT Background T‐cell lymphoblastic lymphoma (T‐LBL) and T‐cell acute lymphoblastic leukemia (T‐ALL) are considered a single biological entity, distinguished primarily by the extent of bone marrow infiltration. This distinction becomes diagnostically challenging in patients with borderline marrow blast counts and predominantly extramedullary ...

Imprint cytology of testicular carcinoid.

The Journal of the Japanese Society of Clinical Cytology, 2001
背景:まれな精巣カルチノイドの1例を経験したのでその捺印細胞所見を中心に報告する.症例:症例は64歳, 男性.肉眼的血尿を主訴とし当院受診となった.左精巣に3cm大の腫瘤を触知, 画像検査にて精巣腫瘍を疑い左高位除睾術を施行した. 捺印細胞像としては, 腫瘍細胞は孤立散在性あるいは疎な結合を示す平面的な集団として認められた.核は円形でクロマチンは細穎粒状で均等に分布したものが多く, 裸核の細胞や, 細穎粒状の豊富な細胞質を持つ細胞が多数認められた. こうした所見よりセミノーマあるいはカルチノイドが疑われたが確定には至らなかった. その後, 組織学的な検索によりカルチノイドと診断された.結語:まれな精巣カルチノイドを経験した.

ICSH Guidance on Bone Marrow Examination and Reporting

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Examination of the bone marrow (BM) remains fundamental to the diagnosis, classification, prognostication, and monitoring of hematolymphoid and other disorders affecting blood cell production. Since publication of the International Council for Standardization in Haematology (ICSH) guideline in 2008, advances in diagnostic technologies, disease

DNA Methylation and Transcriptomic Profiles of Wilms Tumour Reveal New Deregulated Genes and Epigenetic Processes Relevant for Tumour Stratification and Management

International Journal of Cancer, Volume 159, Issue 11, Page 2736-2754, 1 December 2026.
ABSTRACT Wilms Tumour (WT), the most common kidney cancer in children, presents features of altered kidney development and frequently exhibits molecular alterations at the 11p15.5 imprinted locus, affecting the IGF2 and H19 genes, which contribute to tumour growth and predisposition.

Combined CT guided tru-cut biopsy and imprint cytology in the diagnosis of bone tumors and tumor like lesions

Asian Journal of Medical Sciences, 2016
Background: Bone lesions are often histologically heterogenous. The advantage of tru-cut biopsies in this context is that they provide a safe and accurate biopsy technique that can be performed in less specialized centers.

Imprint cytology in pituitary adenoma

The Journal of the Japanese Society of Clinical Cytology, 2011
目的 : 下垂体腫瘍に対し捺印細胞診を行い, 腺腫細胞の特徴を明らかにし, 術中迅速診断に有用であるか検討を行った.方法 : 下垂体腺腫摘出 94 例から術中迅速組織診検体を用いて捺印標本を作製し, その組織像と比較検討した.成績 : 下垂体腺腫 86 例 (91.5%) で下垂体腺腫の確認が可能であった. また, 組織亜型分類では, fibrous body や分泌顆粒などの特徴的な細胞内構造物に加え, 細胞形状, 細胞結合性, 核の位置などの細胞所見を総合的に捉えることによって, 3 群 (GH-PRL-TSH 群, ACTH 群, FSH-LH/ナルセル群) に分類可能であった.結論 : 下垂体腺腫の捺印細胞診は, 腺腫細胞の特徴を十分に捉えることが可能であり ...

Prepartum Heat Stress Dysregulates Immune Resilience in Postpartum Dairy Cows

The FASEB Journal, Volume 40, Issue 20, 31 October 2026.
Increasing environmental temperatures pose a major challenge to animal welfare by inducing heat stress and increasing the incidence of disease. Immune resilience is essential for maintaining animal health; however, the mechanisms linking heat stress to immune dysfunction and disease remain unclear.
