This case report details a rare epidermoid cyst found in the submandibular region of a 69-year-old male. Surgical removal was successful, with no recurrence observed after 28 months, highlighting a unique presentation of this common cyst type.
Area of Science:
- Oral and Maxillofacial Surgery
- Dermatology
- Pathology
Background:
- Dermoid and epidermoid cysts typically occur in the midline or sublingual floor of the mouth.
- Epidermoid cysts are benign cystic tumors that can arise from ectopic skin elements.
Purpose of the Study:
- To report a rare case of an epidermoid cyst located in the submandibular region.
- To describe the clinical presentation, diagnostic imaging, surgical management, and histopathological findings of this unusual case.
Main Methods:
- A 69-year-old male presented with a palpable mass in the right submandibular region.
- Magnetic Resonance Imaging (MRI) revealed a cystic lesion measuring 3.5 × 3.0 cm.
- Cystectomy was performed under general anesthesia, preserving the submandibular gland.
Main Results:
- Histopathological examination confirmed the cyst was lined by stratified squamous epithelium without skin appendages, consistent with an epidermoid cyst.
- The cyst was mobile, elastic, and soft, with normal overlying skin.
- The patient experienced an uneventful postoperative recovery.
Conclusions:
- Epidermoid cysts, though rare, can occur in the submandibular region.
- Surgical excision is an effective treatment, with preservation of adjacent structures like the submandibular gland being feasible.
- Long-term follow-up demonstrated no recurrence, supporting the efficacy of surgical management.

Exocrine Glands: Types of Secretions
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...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Exocrine Glands: Methods of Secretion
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...
