Utility of shear wave elastography in evaluation of children with chronic kidney disease.

Background: Shear wave elastography (SWE) is proven for liver fibrosis. However, there are challenges in assessing the kidney owing to its surrounding structures, retroperitoneal location, and visceral fat. Kidney biopsy is the gold standard for estimating fibrosis, but is associated with inherent risks of bleeding and sedation.

Case of angioimmunoblastic T-cell lymphoma presenting as peripheral and bone marrow plasmacytosis: A diagnostic conundrum.

Angioimmunoblastic T-cell lymphoma (AITL), a subtype of peripheral T-cell lymphoma (PTCL), is associated with unique clinical, morphological, and immunohistochemical features. The peripheral circulation might show presence of an occasional reactive plasma cell but significant plasmacytosis masquerading as plasma cell leukemia is rare. We report a case of AITL in a 42-year-old male, who presented with two-month history of generalized lymphadenopathy.

Renal Allograft Malakoplakia Presenting as a Pseudotumoral Lesion.

Malakoplakia is an uncommon inflammatory disease that can involve many organ systems but is often encountered in the urogenital tract. Kidney allograft malakoplakia is even rarer and can have a diffuse parenchymal or a pseudotumoral presentation. We describe a case of grafi malakoplakia in an adult female, who presented with dull aching pain in the right loin, fever, and vomiting.

Optochiasmatic Cavernomas: Updated systematic review and proposal of a novel classification with surgical approaches.

Cavernomas are histologically benign vascular malformations found at different sites in the brain. A rare site for such cavernomas, however, is the anterior optic pathway, comprising the optic nerve, chiasma, and optic tract-called optochiasmatic cavernomas (OCC). These lesions usually present with sudden onset or progressive vision loss, headache, and features mimicking pituitary apoplexy.

A Rare Sparkle: A Case of Calcified Kidneys in a Young Infant With Renal Failure.

Primary hyperoxaluria-1 (PH1) is an autosomal recessively inherited rare genetic condition due to the deficiency of the hepatic enzyme alanine:glyoxylate aminotransferase which leads to high systemic levels of oxalate and subsequently, early end-stage renal disease and death. Here, we present a case of a three-month-old male infant who presented with loose stools, reduced oral intake, and decreased activity for 12-13 days along with edema and a peeling rash on cheeks, lips, and genitalia. During the entire duration of the inpatient stay, the child was oligoanuric.

Gangliocytic Paraganglioma of the Duodenum: A Masquerader.

Gangliocytic paraganglioma (GP) is a rare tumor that most commonly arises from the duodenum and is characterized pathologically by 3 cell types: epithelioid, spindle, and ganglion cells. GP is often difficult to differentiate from a neuroendocrine tumor on the basis of preoperative imaging, and the diagnosis is based on final histopathologic and immunohistochemical analysis. We report the case of a 28-year-old male who presented with pain in the abdomen, bilious vomiting, and weight loss.

Correlation between androgen and estrogen receptor expression and clinicopathologic features in carcinoma urinary bladder.

Introduction: The molecular mapping of cancers by the Cancer Genome Atlas Project has accelerated the quest for new therapeutic targets for urinary bladder cancer, including sex steroid receptors. Previous studies have demonstrated conflicting results on their relationship with bladder cancer, and there is sparse data on their expression in the Indian population. The aim of our study is to examine the expression of androgen receptors (AR) and estrogen receptors (ERα and ERβ) in patients with bladder cancer and their correlation with clinicopathologic features.

Ultrastructural Changes in Autopsy Tissues of COVID-19 Patients.

Introduction: The COVID-19 pandemic resulted in substantial morbidity and mortality across the world. The prognosis was found to be poor in patients with co-morbidities such as diabetes, hypertension, interstitial lung disease, etc. Although biochemical studies were done in patient samples, no study has been reported from the Indian subcontinent about ultrastructural changes in the vital organs of COVID-19 patients.

Mortality and Its Predictors in COVID-19 Patients With Pre-existing Interstitial Lung Disease.

Background The data on the impact of coronavirus disease 2019 (COVID-19) on interstitial lung disease (ILD) is still limited. To the best of our knowledge, there has been no study from India to date to assess the impact of COVID-19 in patients with preexisting ILD. We undertook this study to assess the clinical outcome of ILD patients admitted to our hospital with COVID-19.

Risk Stratification of Pleural Fluid Cytology Based on the International System for Reporting Serous Fluid Cytology in a Tertiary Care Centre.

Background: The International Academy of Cytology and the American Society of Cytopathology proposed the international system for reporting serous fluid cytology (TISRSFC) in 2019 to form uniform reporting terminologies for fluid cytology. This system defines a spectrum of diagnostic categories to be used in daily clinical practice. Fluid cytology is a widely accepted, cost-effective, minimally invasive earliest diagnostic method for the investigation that aids management decisions.

Umbilicated papulonodules on the elbows with purpuric papules on the fingers.

This case describes an unusual cutaneous presentation. Our patient had purpuric papules on the fingers and umbilicated nodules over the elbows, and interestingly, both lesion types showed similar histopathological features of necrobiotic granuloma with neutrophils.

Cervical Thymic Cyst with parathyroid tissue - a diagnostic conundrum.

Cervical thymic cysts are relatively rare benign cystic lesions that tend to be diagnosed clinically as branchial cysts, which usually present as painless, enlarging neck masses. They can occur anywhere along the normal path of descent of thymic primordia from the angle of the mandible to the sternal notch, with mediastinal extension observed in approximately 50% of cases. They are usually seen in the first decade of life on the left side with a male predominance.

ALK-positive anaplastic large cell lymphoma of skeletal muscle masquerading as soft tissue sarcoma.

Anaplastic large cell lymphoma (ALCL) is a subtype of T cell non-Hodgkin's lymphoma and can present as an extranodal disease. Primary ALCL of skeletal muscle is rare. We report a case of ALK-positive ALCL involving the left thigh and anterior chest wall in a 12-year-old male child.

Pyoderma gangrenosum at an episiotomy site in successive pregnancies: A case report.

Pyoderma gangrenosum (PG) is an ulcerative, neutrophil-predominant inflammatory disease of the skin that commonly presents as painful ulcers. PG during pregnancy is extremely rare. We report the case of a 28-year-old woman with a painful, rapidly progressive ulcerative lesion at an episiotomy site presenting 16 days following a vaginal delivery.
