Cytology of an Axillary Mass: A Rare Case.

This is an interesting case of rhabdomyosarcoma, presenting at an unusual site and diagnosed on FNAC. The smears depict the typical malignant small round cell morphology and tigroid background. It illustrates the role of cell block and immunohistochemistry as important ancillary adjuncts to morphology.

Warthin-like Papillary Thyroid Carcinoma: A Case Report and Review of the Literature.

Warthin-like subtype of papillary thyroid carcinoma (WLPTC) is a rare subtype of papillary thyroid carcinoma. This PTC subtype shows some pattern resemblance to Warthin tumors of the salivary gland, which confers its name but is a not genetically similar to salivary Warthin tumor, with the most frequent genetic change in WLPTC being BRAF p.V600E, the most frequent genetic driver of PTC.

Correlation of Narrow Band Imaging Patterns with Histopathology Reports in Head and Neck Lesions.

Introduction: Head and neck malignancies are associated with poor prognosis and poor quality-of-life if detected late. Narrow-Band-Imaging(NBI) is one of the important tools, which helps in detecting these lesions earlier. By using narrow-wavelength(400-550 nm) it enhances the mucosal and submucosal vascularity against the pale mucosal background which helps us detecting benign, pre-malignant and malignant lesions.

Metastatic Renal Cell Carcinoma Masquerading as a Laryngeal Tumor: A Case Report.

Renal cell carcinoma (RCC) commonly metastasizes to various organs such as the lungs, liver, bones, and brain. However, isolated metastases to the head and neck region, especially the larynx, are very rare. This report presents a case of laryngeal growth that was eventually confirmed to be a metastatic deposit from an undiagnosed RCC.

Carotid Body Tumors: Institutional Experience of 10 Cases and a Review of Literature.

Carotid body tumors are slow growing neck masses that arise from the neural crest cells at the carotid bifurcation. Majority are asymptomatic and are diagnosed incidentally. Surgical excision is accepted as the treatment of choice to reduce complications.

A rare maxillofacial manifestation of acute lymphoblastic leukemia in a 9-year-old child.

Acute lymphoblastic leukemia (ALL) is considered as the most common malignant neoplasm of childhood and the frequent cause of death from cancer before 20-years of age. The facial swelling mimicking a maxillofacial tumor is rarely associated with ALL. Clinicians should be aware of such rare manifestation of ALL.

An Incidentally Detected Case of Atypical Bronchial Carcinoid on Stress Myocardial Perfusion SPECT/CT.

Myocardial perfusion imaging is primarily done to look for stress-induced perfusion defects in patients suspected of having coronary artery disease. However, the rotating raw images can provide significant information on the surrounding structures. The lungs lie near the heart, and any abnormality showing increased uptake can be seen on myocardial perfusion imaging.

Malignant gastrointestinal neuroectodermal tumor: A case-based review of literature.

Malignant gastrointestinal (GI) neuroectodermal tumor is an extremely rare entity that was first described by Zambrano et al. in 2003 as "clear cell sarcoma (CCS)-like tumor of the GI tract." It shares some of the histopathological features of CCS but lacks the immunohistochemical (IHC) reactivity for melanocytic markers.

Second Primary Spindle Cell Carcinoma of the Tongue: A Rare Histology.

Spindle cell carcinoma (SpCC) is a rare variant of poorly differentiated squamous cell carcinoma (SCC), characterised by the presence of both squamous (carcinomatous) and spindle cell (sarcomatous) elements. Early detection and improvement in treatment for oral SCC lead to prolonged survival, thereby increasing the frequency of second primary tumours (SPTs) in the oral cavity. In this paper, we report a case of SpCC of the tongue in a 62-year-old male with a history of SCC; the right lateral border of his tongue status post-treatment completion four years ago, now presented with a polypoidal growth over the tip of his tongue for four months.

Signet ring cell lymphoma of follicular type with BCL2 gene rearrangement: A rare case with a short review of literature.

A case of signet ring cell lymphoma of presacral lymph node is reported. The patient was diagnosed as follicular lymphoma on the basis of clinical and laboratory features, including immunohistochemistry (IHC) and gene rearrangement studies. Light microscopy examination showed neoplastic atypical cells with signet ring cell morphology in core biopsy of lymph node that stained for B-cell markers by IHC.

Metastatic primary gastric melanoma: a rare clinical presentation and a review of literature.

Primary gastric melanoma is a rare clinical finding. It presents with upper gastrointestinal symptoms like abdominal pain, weight loss and melaena. It is often difficult to differentiate a primary gastric melanoma from primary cutaneous melanoma with gastric metastasis.

Application of the Indian Academy of Cytologists Recommendations for Reporting Serous Fluid Cytopathology in Routine Reporting of Ascitic Fluid Specimen and Assessment of the Risk of Malignancy.

Background: A five-tiered reporting system for effusion fluid cytology has been published by the Indian Academy of Cytologists (IAC). Only a single study has evaluated the applicability of this system in routine reporting.

Aims: We intend to evaluate the practical utility of this system in routine reporting of ascitic fluid cytology.

Inguinal lymph node metastasis in treated breast cancer: an extremely rare presentation and review of literature.

Metastasis to inguinal lymph nodes from breast cancer is extremely rare and only a handful of cases have been reported in the literature to date. We report a case of a postmenopausal female patient who was a treated case of right breast cancer and developed inguinal metastases after 9 months. An excisional biopsy of the lesion confirmed the diagnosis.

Response to Immunotherapy in Adenocarcinoma Lung With Gastric Metastasis: A Rare Case Report and Review of Literature.

Worldwide lung cancer is the most common cause of cancer mortality. Most of the lung cancer patients present with advanced disease at the time of diagnosis, and in that case, the prognosis is poor even with treatment. The most common sites of metastases in non-small-cell lung cancer are the brain, bone, liver, and adrenal gland.

SMARCA4/BRG1-Deficient Sinonasal Carcinoma.

Context.—: Molecular analysis of poorly differentiated/undifferentiated sinonasal neoplasms has resulted in identification of a growing number of genetically defined tumors. SMARCA4-deficient sinonasal carcinoma is one such recently described entity that emerged from within sinonasal undifferentiated carcinoma (SNUC), neuroendocrine carcinoma (NEC), and teratocarcinosarcoma (TCS).

Cytomorphological features of Mammary Analog secretory carcinoma of parotid gland: Report of 3 cases and review of literature.

Mammary analog secretory carcinoma (MASC) of salivary gland is a recently described entity. Due to its rarity and cytomorphological overlap with other salivary gland tumors, it is often difficult to recognize on cytology. Here we describe three such cases with their histopathological correlation.

Extensive malignant melanoma of the oral cavity: a rare occurrence.

Primary malignant melanoma of the oral cavity is a rare tumor in clinical practice. Extensive malignant melanomas are still very rare in the literature. Patients with malignant melanoma of oral cavity are often diagnosed at the advanced stage of the disease due to their painless and nonspecific radiological findings.
