Introduction: Cutaneous leishmaniasis (CL) is a parasitic skin infection which can be debilitating. This study was performed to determine the vascular changes in the histopathology of CL. Methods: Thirty-seven patients with CL were included in a prospective study. A 4 mm punch biopsy was obtained from the border of the lesion. After histopathologic processing and H&E staining, it was reviewed ...

A patient is described who presented with visual loss due to infiltration of the optic chiasm by chronic lymphocytic leukaemia. This case demonstrates intracranial infiltration as a primary presentation of chronic lymphocytic leukaemia without lymphoreticular involvement and, to our knowledge, is the first report of a chiasmal syndrome due to this lymphoproliferative disorder.

a novel type of brainstem-predominant encephalomyelitis was first described as chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (clippers) in 2010 by pittocket al and then few additional patients were reported. here we report a 50-year-old iranian male who presented with a number of clinical features described as typical for clippers. the association...

A 44-year-old Japanese man consulted to our hospital because of cough and sputum. Chest-XP and CT revealed diffuse reticular opacities in both lungs.A transbronchial lung biopsy (TBLB) showed a moderate infiltration of lymphocytes in the alveolar septae. He was diagnosed as interstitial pneumonia, and treated by drugs. One year later, his condition deteriolated, and a large open biopsy was perf...

Jessner lymphocytic infiltration of the skin is an uncommon skin disorder characterized by benign accumulations of lymphocytes by a “coat-sleeve”-like perivascular infiltration in the skin [1]. These small lesions are solid, pink or red in colour and appear on the face, neck and back. The lesions may remain unchanged for several years and then spontaneously disappear, leaving no scars [2]. Prog...

Background Tsutsugamushi disease is an acute, febrile, infectious disease caused by Orientia tsutsugamushi. Several studies investigating the histopathologic findings of eschars in tsutsugamushi disease reported leukocytoclastic vasculitis and neutrophil infiltration as the major findings. However, these findings may result from secondary changes following tissue necrosis. The histopathologic f...
