Tall cell variant of invasive papillary breast carcinoma is exceedingly rare, with only 30 cases reported in the literature. This report describes a case of a 47-year-old woman who presented to the clinic with bilateral breast masses on a screening mammogram. The patient was lost to follow-up, but she presented again after 4 years when the right breast mass significantly grew in size over several months. Mammography showed a 1.9 cm right breast mass and a 2.3 cm left breast mass. Ultrasound-guided core biopsy revealed right breast triple negative invasive carcinoma of the tall cell papillary variant and left breast fibroadenomatoid nodules. She underwent bilateral lumpectomies with a right sentinel lymph node biopsy and was started on chemotherapy after surgical excision.

T-cell acute lymphoblastic leukaemia (T-ALL) is a rare aggressive haematological malignancy characterised by the clonal expansion of immature T-cell precursors. It accounts for 15% of paediatric and 25% of adult ALL. T-ALL is associated with the overexpression of major transcription factors (TLX1/3, TAL1, HOXA) that drive specific transcriptional programmes and constitute the molecular classifying subgroups of T-ALL.

Phospholipids are the most abundant component in lipid membranes and are essential for the structural and functional integrity of the cell. In eukaryotic cells, phospholipids are primarily synthesized de novo through the Kennedy pathway that involves multiple enzymatic processes. The terminal reaction is mediated by a group of cytidine-5'-diphosphate (CDP)-choline /CDP-ethanolamine-phosphotransferases (CPT/EPT) that use 1,2-diacylglycerol (DAG) and CDP-choline or CDP-ethanolamine to produce phosphatidylcholine (PC) or phosphatidylethanolamine (PE) that are the main phospholipids in eukaryotic cells.

Approach to the Patient with Thyroid Cancer: Selection and Management of Candidates for Lobectomy.

Thyroid lobectomy has gained increasing popularity over the past decade as a treatment for differentiated thyroid cancer (DTC), largely due to a rise in the diagnosis of low-risk cancers and evidence showing no benefit from radioiodine in low-risk disease. Multiple studies have confirmed lobectomy as an effective and safe option. Its advantages over total thyroidectomy include lower complication rates and a reduced need for lifelong levothyroxine (LT4) therapy.

Objective: To analyze the related factors of treatment failure in children with acute lymphoblastic leukemia (ALL) in real-world.

Methods: The clinical data of 1414 newly diagnosed children with ALL admitted to five hospital in Fujian province from April 2011 to December 2020 were retrospectively analyzed. Treatment failure was defined as relapse, non-relapse death, and secondary tumor.

The homeodomain protein homeobox (HOPX), a multifaceted regulator of cellular functions and developmental processes, is predominantly expressed in stem cells across diverse tissues; it has also emerged as a tumour suppressor in various solid cancers. However, its role in haematological malignancies still remains undefined. This study aimed to elucidate its significance in T-cell acute lymphoblastic leukaemia (T-ALL).
