Urologic Endoscopic Procedure: Cystoscopic Examination01:28

Urologic Endoscopic Procedure: Cystoscopic Examination

3.7K
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...

Oral Cavity01:11

Oral Cavity

3.3K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Bone Cells and Tissue01:30

Bone Cells and Tissue

8.7K
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

4.3K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

913
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Area of Science:

  • Oral and Maxillofacial Pathology
  • Odontogenic Tumors
  • Cystic Lesions of the Jaw

Background:

  • The Calcifying Odontogenic Cyst (COC) was first described in 1962, with the term Calcifying Cystic Odontogenic Tumor (CCOT) recommended by WHO in 2005.
  • COCs are rare lesions characterized by 'ghost cell' keratinization and spherical calcifications, often resembling ameloblastoma.
  • Terminology and classification have been debated due to the heterogeneity of COC lesions.

Observation:

  • A classic case of COC/CCOT is presented in a 37-year-old male patient.
  • The lesion presented as a well-circumscribed, solid or cystic mass.
  • Clinical and radiographic findings suggested a provisional diagnosis.

Findings:

  • Histological examination confirmed the diagnosis of Calcifying Odontogenic Cyst (COC) / Calcifying Cystic Odontogenic Tumor (CCOT).
  • The characteristic 'ghost cell' keratinization and calcifications were noted.
  • The case highlights the diagnostic process for this rare odontogenic lesion.

Implications:

  • Accurate diagnosis of COC/CCOT is crucial due to its varied presentation and potential for recurrence.
  • Understanding the clinicopathologic spectrum aids in appropriate management strategies.
  • This case contributes to the literature on rare odontogenic tumors, emphasizing the importance of histological confirmation.
