A 24-year-old man presented with hemoptysis and was found to have an endobronchial mass obstructing the superior segmental bronchus of his left lower lobe. Further testing revealed a solid and cystic endobronchial mass with focal calcification, which was diagnosed as mucoepidermoid carcinoma, an uncommon tumor containing mucus-secreting, squamous, and intermediate cells often showing glandular formations and calcifications.

The document discusses Mucoepidermoid carcinoma, which is the most common malignant salivary gland tumor. It arises from the ductal system of major and minor salivary glands. The document describes the clinical features, histopathological features, grading, variants, differential diagnosis and management of Mucoepidermoid carcinoma. It is graded as low, intermediate or high grade based on histopathological characteristics like presence of cystic spaces, cellular atypia and proportion of cell types.

Pitfalls in minor salivary gland neoplasmsEkta Jajodia
油
1. Minor salivary gland neoplasms can be difficult to diagnose based on limited tissue sampling from biopsies due to overlapping histological features between benign and malignant tumors.
2. Both benign and malignant tumors may appear circumscribed and show similar growth patterns, cytomorphology, stroma, and immunoreactivity, limiting the ability to render a specific diagnosis.
3. A diagnosis of mucoepidermoid carcinoma can generally be made on biopsy due to its characteristic cell types, but distinction between other tumors often requires examining features of invasion in completely excised specimens.Salivary gland pathology

This document summarizes information about pleomorphic adenoma, the most common tumor of the parotid gland. It is a benign mixed tumor composed of epithelial and spindle-shaped cells in a myxoid stroma. On pathology it shows well-differentiated epithelial cells and spindle/stellate cells in an abundant mucoid matrix. Clinically it presents as a slow-growing, painless swelling of the parotid gland. The treatment is superficial parotidectomy to completely remove the tumor while preserving the facial nerve. There is a small risk of recurrence, particularly if the margins are positive, or of malignant transformation after many years.Salivary gland pathology

Mucoepidermoid carcinoma is the most common malignant salivary gland tumor, making up 10-20% of major and minor salivary gland tumors. It occurs most often in the parotid gland and presents as a painless swelling. Diagnosis is made through biopsy and tumors are graded as low, intermediate, or high based on cell type proportions and aggressiveness. Treatment involves surgical removal of the affected gland with wider margins for higher grade tumors and possible radiation therapy or neck dissection for advanced cases.Fnac of salivary gland tumour

Pleomorphic adenoma is the most common salivary gland tumor, accounting for 60% of cases. It occurs most often in the parotid glands and presents as a painless, firm mass. Histologically, it contains both epithelial and mesenchymal elements arranged in a trabecular pattern within a fibrous stroma. Treatment involves complete surgical removal of the tumor with adequate margins to prevent recurrence due to microscopic projections outside the capsule. Imaging such as CT or MRI is used to identify the location and characteristics of the tumor prior to surgery.Classification breast carcinoma

On December 9, 2024, the American Diabetes Association (ADA) released the Standards of Care in Diabetes - 2025, which outlines evidence-based guidelines for diagnosing and managing diabetes and prediabetes. These guidelines, based on the latest scientific research and clinical trials, cover treatment approaches for both adults and children. They also address strategies to prevent or slow the progression of type 2 diabetes and related health conditions, including obesity.
The updated standards include care recommendations designed to improve health outcomes. The ADA revises these guidelines annually through its Professional Practice Committee (PPC), which consists of experts from various fields including physicians, nurse practitioners, certified diabetes care and education specialists, registered dietitian nutritionists, pharmacists, and methodologists.
The Standards of Care in Diabetes - 2025 is available online as a supplement to the January 2025 issue of Diabetes Care. A mobile application compatible with iOS and Android devices, it offers the latest guidelines, interactive tables, and algorithms for quick reference.
The ADA, a voluntary health organization, has focused on diabetes research and public health for 84 years. With 136 million Americans affected by diabetes or prediabetes, the organization continues to support education, program development, and advocacy efforts.Biography and Professional Career of Dr. Seth Eidemiller
