Cellular Adaptation IV: Dysplasia and Metaplasia01:24

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Area of Science:

  • Oral pathology
  • Surgical oncology

Background:

  • Pleomorphic adenoma is the most common salivary gland neoplasm.
  • Minor salivary gland tumors are less common than major salivary gland tumors.

Observation:

  • A 58-year-old male presented with a slow-growing mass in the retromolar region.
  • Differential diagnoses included fibroma, minor salivary gland tumor, and mucocele.

Findings:

  • Microscopic examination confirmed pleomorphic adenoma with epithelial and myoepithelial cell proliferation.
  • The tumor exhibited a ductal pattern with areas of sheet-like growth.

Implications:

  • This case highlights the rare occurrence of pleomorphic adenoma in the retromolar area.
  • Surgical excision is the primary treatment, with no recurrence observed during follow-up.
