Primary Spinal Intradural Extramedullary Ewing's Sarcoma/Peripheral Neuroectodermal Tumour Masquerading Clinically as a Neurogenic Tumour: A Case Report and Review of Literature.

Ewing's Sarcomas (ES)/Peripheral neuroectodermal tumour (pPNET) are heterogenous group of rare, highly malignant, undifferentiated primitive round-cell neoplasms of neuroectodermal origin. pPNETs are seldom observed to involve the spine of which Spinal Intradural Extramedullary Extraosseous Primary ES/pPNET are extremely rare. We report a case of a 23-year-old male with complaints of low backache and hip pain radiating to the left inguinal region for four months.

Role of cytopathology in diagnosing phaeohyphomycosis masquerading as nerve abscess in a lepromatous leprosy patient: A case report.

Introduction And Importance: Phaeohyphomycosis is a rare fungal infection primarily affecting immunocompromised individuals. Its clinical manifestations are diverse, and diagnosis can be challenging, particularly when lesions mimic other conditions.

Case Presentation: A 66-year-old male, with a history of irregular leprosy treatment and prolonged steroid use, presented with symptoms suggestive of a nerve abscess.

Atypical Hansen's Disease Mimicking Xanthogranuloma: Role of Cytology.

Fine needle aspiration cytology is a simple, safe, and effective technique that can be used in the diagnosis of cutaneous diseases. Here, we present a case of Hansen's disease with an erythematous dermal nodule mimicking xanthogranuloma clinically. In our scenario, since leprosy is considered eliminated in India, the presentation of patients with classical signs and symptoms is becoming rare.

Evaluation of Immunohistochemical Expression of Enhancer of Zeste Homolog 2 (EZH2) and Its Association With Clinicopathological Variables in Carcinoma Cervix.

Introduction:  Carcinoma cervix is the fourth most common cancer worldwide and is one of the leading causes of cancer death in women. Recently, immunohistochemical expression of biomarkers has been utilized as indicators of disease progression, aggressiveness for predicting the prognosis in various cancers. DNA methylation of genes plays an important role in pathogenesis of carcinoma cervix and detection of aberrant methylation can be utilized for detection of carcinoma cervix and monitoring of its progression.

Elusive Primary in Low Grade Mucoepidermoid Carcinoma: Dilemma of Chronology and Terminology.

Salivary gland tumours constitute an uncommon and diverse group of neoplasms that vary considerably in their histology and biologic behaviour. As per Globocon 2018, salivary gland malignancy account for 0.3% of all cancer cases and 0.

Histopathologic spectrum and clinical correlation of lesions of jaw - a series of 60 cases.

Odontogenic tumors have the potential for the development of malformations of the teeth as well as the surrounding tissue. Sound knowledge of various types of jaw lesions and their characteristics will help the clinician with timely measures and management. Our main aim was to study the histopathological nature of various jaw lesions retrieved from biopsies and resected specimens.

Preliminary Experience in Post-COVID-19 Mycoses: A Pathologist's Perspective.

Background Coronavirus disease is caused by the severe acute respiratory syndrome coronavirus-19. Because of co-morbidities and indiscriminate use of steroids and antibiotics, the incidence of opportunistic fungal infections has increased in COVID-affected individuals. Aims and objectives The aim of the study is to analyze the various tissue reaction patterns of COVID-19-associated mucormycosis in the surgical debridement specimens using routine hematoxylin and eosin (H&E) stain and special stains like periodic acid-Schiff (PAS), Grocott-Gomori's methenamine silver (GMS), Masson trichrome (MT) and Prussian blue (PB), and to understand the pathogenesis of COVID-19 sequelae.

Extensive mucoepidermoid carcinoma-like differentiation in follicular carcinoma of the thyroid.

Mucoepidermoid carcinoma (MEC) is a rare malignant thyroid neoplasm. Cases of MEC with papillary, insular, and anaplastic thyroid carcinoma have been reported. Here, we present a case of follicular carcinoma with extensive MEC-like differentiation.

Haemoptysis in Askin's Tumour: Intrapulmonary Presentation of an Extrapulmonary Tumour.

Ewing's sarcoma (ES) is a small round cell sarcoma arising in the bone or soft tissue. Ewing's sarcoma/primitive neuroectodermal tumours (PNET) of the thoracopulmonary region is called Askin's tumour. The common clinical presentations described for this extrapulmonary tumour are fever, chest wall mass with or without pain, dyspnea, and cough.

A Rare, yet Classic Case of Colloid Cyst of Third Ventricle.

Colloid cyst of third ventricle is a rare, benign, congenital lesion that usually presents with headache, and associated with altered cognition, nausea, vomiting, gait ataxia, and blurred vision. A large cyst/growing cyst can cause obstructive hydrocephalus leading to acute rapid neurological deterioration and sudden death. Here we report a classic clinical presentation and histopathological features of colloid cyst of third ventricle with specific emphasis on the importance of rapid diagnosis and management to avoid potentially fatal complications of this otherwise benign lesion.

A Rare Case of Renal Pelvic Hydatid Cyst Masquerading as Renal Calculi.

Hydatid disease of urinary tract is most common in the kidney. In kidney, hydatid cysts are most commonly found in the renal parenchyma. Isolated hydatid cysts in the renal pelvis are extremely rare with only three cases reported in the literature.

Cytomorphological spectrum of hand, wrist, and foot lesions at tertiary care center in central India.

Background: Fine-needle aspiration cytology (FNAC) being a fast technique is used as a primary investigation to diagnose wide spectrum of hand, wrist, and foot lesions. These sites are prone to trauma, reparative, and infectious process, which forms mass lesions mimicking neoplasia. Our study highlighted the importance of FNAC with the chance of reduction in biopsy or excision.

FNAC of Breast Lesions with Special Reference to IAC Standardized Reporting and Comparative Study of Cytohistological Grading of Breast Carcinoma.

Background: International Academy of Cytology (IAC) has established a process to produce comprehensive and standardized approach to fine-needle aspiration cytology (FNAC) reporting. They have categorized the breast lesions in C1 to C5. (C1-Insufficient material, C2-Benign, C3- Atypical, C4-Suspicious & C5-Malignant).

Medullary thyroid carcinoma co-existent with Hashimoto's thyroiditis diagnosed by a comprehensive cytological approach.

Fine-needle aspiration cytology (FNAC) is a preliminary test for the diagnosis of thyroid lesions. We hereby report a rare case of medullary thyroid carcinoma (MTC) co-existing with Hashimoto's thyroiditis (HT). This case was substantiated with ancillary tests on cytology material to give a novel insight.

Cytomorphology of Skin Adnexal Tumors: A Tale of Two Scalp Swellings.

The primary and metastatic tumors of the skin can be effectively diagnosed by fine needle aspiration cytology (FNAC); however, the cytomorphological features of skin adnexal tumors are rarely described in the literature. We hereby describe the cytological features of two histologically confirmed cases of benign skin adnexal tumors. Case 1 is of a 46-year-old female who presented with an elevated firm nodule over the scalp.

Aims: Tzanck smear is an old but useful test for diagnosis of cutaneous dermatoses. The aim of this study was to highlight the potential usefulness and diagnostic pitfalls of Tzanck smear for diagnosis of cutaneous dermatoses and infections.

Materials And Methods: This hospital based cross-sectional study was carried out on all Tzanck smears received for a period of twenty months (January 2014-August 2015).

Loose bodies in right elbow joint: Post traumatic? or post infective?

Tuberculous osteomyelitis after open fracture is uncommon. Early diagnosis of tubercular arthritis is difficult because of insidious onset, indolent process and mild or non specific local or systemic symptoms. This case report describes the fibrinous loose bodies in elbow joint of a patient who sustained a compound fracture presented with chronic non healing discharging sinus.
