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...

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) syndrome is a clinically and radiologically distinct pontine-predominant perivascular neuroinflammation showing T lymphocyte infiltration. It is assumed to have an autoimmune or other inflammatory mediated pathogenesis. We report the first known case of CLIPPERS in East Asia, characterized b...

Figure 1. Photograph of the legs. A large, thickened, firm, hyper/hypopigmented plaque is evident on the left leg. Figure 2. Biopsies of affected skin (A) and contiguous tibialis anterior muscle and fascia from the left leg (B–D). (A) The der-mal collagen is thickened, packed, and hyalinized. The subcutaneous fat is extensively replaced by collagen, and perivascular inflammatory infiltrates are...

The relation between immunohistological findings in biopsy specimens of apparently normal skin, HLA antigens, and rheumatoid factors (RF) was studied in 120 patients with rheumatoid arthritis (RA), selected for treatment with D-penicillamine. Perivascular infiltration (PVI) of more than three mononuclear cells was present in 77 (68%) of 114 patients, accompanied usually by the presence of IgM o...

BACKGROUND Nonspecific interstitial pneumonia (NSIP) is characterized by interstitial infiltration of T lymphocytes, and subpopulations of these cells may be associated with the progression of fibrosis. However, few studies evaluate the correlation of prognosis with this characteristic. Therefore, we performed morphological and quantitative analyses of T lymphocytes in patients with NSIP and ev...

introduction: henoch schonlein purpura (hsp) is a self-limited systemic disease with multiorgan involvement. while cutaneous involvement may wary, presenting as itching papules is not a common manifestation. in this report we discuss a case of hsp which was presented solely with itching papules; mistaken for scabies. case presentation: a 7 year old boy presented with itchy palpable papules with...

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 ...

Secondary lung infiltration by lymphomas occurs frequently. To our knowledge, however, no recent studies have attempted to discriminate histologic patterns of lung infiltration in the lymphoma subtypes. We retrospectively evaluated the frequency of lung infiltration and the respective infiltration patterns by lymphomas at autopsy, during an 11-year period. Lymphomas were classified according to...

Cerebral myeloma in a 49-year-old white man took the form of diffuse arachnoid infiltration, intracerebral perivascular cuffing, and frank intracerebral invasion.
