Pattern‐based interpretation of SOX2 expression in ovarian teratomas: avoiding diagnostic pitfalls in the distinction between immature and mature neuroectodermal elements

Histopathology, EarlyView.
Ovarian immature teratoma grading may be confounded by mature neuroectodermal mimics. SOX2 labelled immature neuroepithelium but also mature ependymal and glial tissue, while SALL4 was negative in mature mimics and variably expressed in immature neuroepithelium.

Mature cystic teratoma with co-existent mucinous cystadenocarcinoma: describing a diagnostic challenge—a case report

Journal of Medical Case Reports
Background Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is a rare tumor that few cases have been reported until now. In these cases, either a benign teratoma is malignantly transformed into adenocarcinoma or a collision tumor is ...

Single‐centre analysis of severe Coombs‐positive autoimmune haemolytic anaemia in an HIV‐endemic population

HIV Medicine, EarlyView.
Abstract Introduction Human immunodeficiency virus (HIV) is a rare cause of autoimmune haemolytic anaemia (AIHA) which requires prompt diagnosis and treatment. We compared clinical and laboratory findings in AIHA patients with and without HIV. Methods We included adults with severe AIHA (haemoglobin ≤8 g/dL) diagnosed at a tertiary academic centre ...

20th Anniversary of human‐induced pluripotent stem cells and the role of microscopy

Journal of Microscopy, EarlyView.
Abstract It has been 20 years since the pioneering work of Shinya Yamanaka and Kazutoshi Takahashi at Kyoto University led to the first successful generation of induced pluripotent stem cells (iPSCs) from mouse embryonic and adult fibroblast cells. iPSCs have the capacity to differentiate into any type of cell in the human body, and as such, they have ...

The effect of time to nephrectomy on cancer‐specific mortality in pathological T stage (pT)1b–2 renal cancer

BJU International, Volume 138, Issue 6, Page 1160-1170, December 2026.
Objective To assess the impact of prolonged time to surgery on cancer‐specific mortality (CSM) in patients with pathological T stage (pT)1b–2 N0M0 renal cell carcinoma (RCC) treated with nephrectomy (either partial [PN] or radical [RN]). Within the Surveillance, Epidemiology and End Results (SEER) database (2004–2021), we tested the effect of time to ...

Equine Veterinary Education, Volume 38, Issue 12, Page 642-646, December 2026.
Summary Testicular torsion is a rare condition in horses characterised by a change in the position of the testis due to the testicular mesentery twisting around its own axis; it can occur both when the testis is still in the abdominal cavity and when it has descended into the scrotum.

Ovarian pain in the mare: Clinical implications of mittelschmerz and oestrus‐related behavioural abnormalities

Equine Veterinary Education, Volume 38, Issue 12, Page 661-667, December 2026.
Summary Mittelschmerz is a well‐recognised benign peri‐ovulatory pain syndrome in women and, by physiological analogy, may also occur in mares. In equine practice, peri‐ovulatory ovarian pain has been associated with transient discomfort, colic‐like signs and behavioural changes, although its true clinical relevance remains poorly defined.
