Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.3K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Ovaries01:26

Ovaries

3.5K
The ovaries are roughly the size of almonds and measure approximately 2 to 3 centimeters in length. These paired structures are situated within the pelvic region and are anchored by the mesovarium—a peritoneal extension that also connects them to the wider structure of the broad ligament. The support system extends to the suspensory ligament, housing blood and lymphatic vessels. In addition, the ovarian ligament tethers the ovaries to the uterus.
On the ovarian surface, a layer of...

The Retinoblastoma Gene

3.7K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cushing Syndrome II: Pathophysiology

24
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features...

Abnormal Proliferation02:23

Abnormal Proliferation

4.0K
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...

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Oncology

Background:

  • Oncocytomas are uncommon benign tumors typically affecting salivary or lacrimal glands.
  • These tumors are usually small and rarely present within the orbit.

Observation:

  • A giant unilateral orbital oncocytoma was diagnosed in a 19-year-old male.
  • The tumor caused progressive proptosis, threatening the patient's vision.
  • Significant retro-ocular extension of the lesion was noted.

Findings:

  • Surgical excision was performed using a fronto-orbitozygomatic craniotomy and orbitotomy.
  • Sub-total resection of the giant orbital oncocytoma was achieved.
  • The patient experienced improved proptosis and cosmetic appearance post-surgery.

Implications:

  • This case represents the first documented instance of a giant intra-orbital oncocytoma treated with neurosurgical resection via craniotomy.
  • The findings suggest that craniotomy is a viable approach for large orbital oncocytomas with retro-ocular extension.
  • This case expands the understanding of rare orbital tumor management.
