Lymphocytic infiltration is often seen in breast cancer and has been suggested as a marker of host anti-tumor response but its importance in prognosis remains controversial. Our recent study demonstrated an association between tumor-infiltrating CD8(+) T lymphocytes in invasive breast cancer and better prognosis.

Postmortem examination of 7 neonates with congenital Zika virus infection in Brazil revealed microcephaly, ventriculomegaly, dystrophic calcifications, and severe cortical neuronal depletion in all and arthrogryposis in 6. Other findings were leptomeningeal and brain parenchymal inflammation and pulmonary hypoplasia and lymphocytic infiltration in liver and lungs. Findings confirmed virus neuro...

Extramedullary involvement in early stage chronic lymphocytic leukaemia (CLL) is rare. We report the first case of an incidental finding of gall bladder infiltration in a patient who underwent a cholecystectomy for gallstone pancreatitis with no preceding history of CLL. This case reiterates the importance of subjecting even routine cholecystectomy specimens for histopathology examination in th...

Cerebrospinal fluid mononuclear cells from 40 patients with advanced Gambian sleeping sickness were examined for intracytoplasmic immunoglobulin and for B- and T-lymphocyte markers. About 5% of mononuclear cells were plasma cells. Most of the lymphocytes present were B cells. These findings suggest that the considerable lymphocytic infiltration of the nervous system seen in advanced sleeping si...

We examined the distribution of CD1a⁺ cells and CD8⁺ and CD4⁺ T lymphocytes in prostate cancer (PCa) and correlated these with clinicopathological parameters. We also investigated whether the distribution of these cells was related to the expression of the cell membrane protein B7-H3, a putative negative regulator of the immune response expressed on PCa cells. A cohort of 151 PCa patients treat...

On histology, IgG4-related hypophysitis is essentially similar to lymphocytic hypophysitis besides massive IgG4-positive plasmacyte infiltration. This immunohistochemical study was performed to investigate the presence of IgG4-positive plasmacytes in 14 various inflammatory lesions. Five cases of lymphocytic hypophysitis and a case of granulomatous hypophysitis were either negative or showed on...

The importance of accurate pathological diagnosis is emphasised in the case of a newborn infant who presented with alopecia, a generalised erythrodermatous skin eruption, and hepatosplenomegaly. She subsequently developed generalised lymphadenopathy and recurrent septicaemia and died aged 2 months. The histological findings of widespread lymphocytic, histiocytic, and eosinophilic tissue infiltr...

A 65 year old man developed progressive signs of pontine and medullary dysfunction with striking bilateral paralysis of lateral gaze, dysarthria, dysphagia, and ataxia. A respiratory death occurred seven months from the onset. Pathological examination revealed focal brain-stem changes of perivascular lymphocytic cuffing, microglial infiltration, glial nodules, and neuronophagia. No underlying m...

We report the case of a 53-year-old woman with a personal history of chronic venous insufficiency and recurrent biliary colic who was seen after goiter was detected at during routine medical visit. A physical examination revealed diffuse grade 3 goiter associated with two to four bilateral hard nodules attached to deep planes. There were no adenopathies. No thyroid tenderness or other findings ...
