Summary
This case report details a rare, large epidermoid cyst in the floor of the mouth with both oral and submental components. Histopathology confirmed the diagnosis, highlighting key features of this uncommon oral cavity cyst.
Area of Science:
- Oral pathology
- Surgical oncology
- Dermatopathology
Background:
- Epidermoid and dermoid cysts are rare, accounting for <0.01% of oral cavity cysts.
- This report focuses on a unique case with both oral and submental extension.
Observation:
- A 16-year-old female presented with a 5-month history of a sublingual mass, dysphagia, and chewing difficulty.
- Imaging revealed a large, well-circumscribed cystic mass in the floor of the mouth.
- A firm submental swelling was also noted, extending towards the thyroid notch.
Findings:
- Fine-needle aspiration cytology showed keratin and proteinaceous material.
- Histopathology confirmed an epidermoid cyst with characteristic acidophilic stratum corneum and basophilic granular layer.
- The cyst measured 7.0 × 5 × 4.5 cm.
Implications:
- This case expands the understanding of epidermoid cyst presentation in the oral cavity.
- The submental component mimicked a plunging ranula, emphasizing the need for thorough differential diagnosis.
- Surgical excision is the primary treatment for symptomatic oral epidermoid cysts.

01:29Exocrine Glands: Unicellular and Multicellular Glands
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...
01:13Exocrine Glands: Types of Secretions
Exocrine glands produce and release a variety of glandular products. Exocrine glands can be classified into serous, mucous, or mixed types based on their secretory products.
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

01:21Accessory Structures of the Skin: Sebaceous Glands
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

01:08Exocrine Glands: Methods of Secretion
Exocrine glands are those that release their secretions through ducts. Based on their mode of secretion, they can be classified into merocrine, apocrine, and holocrine.
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine glands...

01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
