Isolated intraosseous extra-gnathic orbital myxoma: a clinicopathologic case report.

A 19-year-old female student presented with painless, progressive proptosis in the right eye for the past six months causing significant cosmetic blemish and double vision. Clinical evaluation revealed normal visual acuity, normal pupillary reflex, severe proptosis, and dystopia. Orbital imaging revealed a heterogeneous mass in superior orbit displacing the globe inferiorly and causing extensive bony erosion of frontal bone superiorly and invading the frontal sinus.

Improving Bethesda Reporting in Thyroid Cytology: A Team Effort Goes a Long Way and Still Miles to Go….

Context: Fine-needle aspiration cytology is the first step in evaluation of thyroid nodules. Although the Bethesda classification for reporting thyroid cytology has been purported that this uniformity in reporting cytology thereby facilitating clinical decision-making, there are also studies indicating that the reporting percentage and the rates of malignancy in each category vary considerably from center to center making the clinical decision more difficult.

Aim And Materials And Methods: We looked at our retrospective cytology and histopathology data of thyroid nodules operated between 2012 and 2014 and then prospectively collected data during 2015-2016.

Plasmacytoid dendritic cells in lymph nodes of patients with human immunodeficiency virus.

Circulating plasmacytoid dendritic cells (PDC) decrease in human immunodeficiency virus (HIV) infection, either from loss or redistribution to lymph nodes (LN). Limited animal and human studies variably showed increased or decreased nodal PDC. CD123 immunostaining was performed on 28 archived LN biopsies (20 reactive) from 25 HIV patients.

Kimura disease with proliferative squamous metaplasia: an unusual finding and a potential diagnostic pitfall.

Kimura disease is a rare form of chronic inflammatory disorder involving subcutaneous tissue, predominantly in the head and neck region and frequently associated with regional lymphadenopathy and/or salivary gland involvement. We present a case of Kimura disease in a 28-year-old male which showed florid squamous metaplasia in the salivary gland ducts and salivary duct inclusions in the intraparotid nodes besides the usual features of Kimura disease. The squamous metaplasia was extensive enough to pose a diagnostic dilemma.

Clear cell sarcoma of the kidney--a study of seven cases over a period of three years.

Unlabelled: Clear cell sarcoma of the kidney (CCSK) can display diverse morphological patterns and mimic various other pediatric renal tumors. An accurate diagnosis of this tumour is important considering the therapeutic and prognostic implications.

Aim: The present study was undertaken to describe the various histological patterns of CCSK.

Cytological evaluation of head and neck tumors in children--a pattern analysis.

A total of 135 pediatric head and neck tumors diagnosed in our institute were reviewed with a view to elucidate the overall cytological patterns and analyze the important cytological features. Ninety-four tumors (69.6%) were aspirated for a primary diagnosis, and in 41 (30.

Renal angiomyolipomas--a study of 18 cases.

Angiomyolipoma is a distinctive neoplasm composed of an intimate admixture of three components, viz. mature adipocytes, smooth muscle cells and blood vessels. This study was undertaken to better define the various morphological patterns of angiomyolipoma and their immunohistochemical profile.

Desmoplastic round cell tumor of childhood: can cytology with immunocytochemistry serve as an alternative for tissue diagnosis?

There are limited reports on the cytology of desmoplastic small round cell tumors (DSRCT). Fine needle aspiration biopsy (FNAB) findings in seven aspirates from four cases of histologically and immunohistochemically confirmed cases were analyzed with the main intention of ascertaining if cytological diagnosis of DSRCT is possible. Also assessed were the immunocytochemistry(ICC) findings in these cases.
