Summary
A benign salivary gland tumor, myoepithelioma, is rare in the head and neck. This case report details a palatal myoepithelioma diagnosed histopathologically and successfully treated with surgery.
Area of Science:
- Pathology
- Oncology
Background:
- Myoepithelioma is a rare, benign salivary gland neoplasm.
- It constitutes 1-1.5% of all salivary gland tumors.
- Diagnosis relies on histopathological examination, identifying myoepithelial cell proliferation.
Observation:
- A case of myoepithelioma in a 46-year-old female is presented.
- The lesion appeared as a well-defined nodular growth on the posterior palate.
- Radiographic imaging revealed bony erosion and invasion.
Findings:
- Histopathology showed sheets of bland spindle and plasmacytoid myoepithelial cells.
- Immunohistochemistry confirmed the myoepithelial origin of the cells.
- The tumor lacked significant chondroid or myxochondroid stroma and ductal components.
Implications:
- Surgical excision with clear margins is an effective treatment for palatal myoepithelioma.
- Benign myoepithelioma has a favorable prognosis with no reported recurrence in this case.
- This case contributes to understanding the clinical and pathological presentation of myoepithelioma.

01:30Classification of Epithelial Tissues: Simple Epithelium
16.4K
Simple epithelium consists of a single layer of cells that lines body cavities and blood vessels. The shape of the cells in the epithelium reflects the function of the tissue. Cells in simple squamous epithelium appear as thin scales with flat, elliptical nuclei that mirror the form of the cell.
Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...

01:22Classification of Epithelial Tissues: Overview
29.4K
Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.

01:29Classification of Epithelial Tissues: Stratified Epithelium
15.7K
Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

01:20Classification of Epithelial Tissues: Glandular Epithelium
18.3K
The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.

43.2K
Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
