Bilateral Annular Isolated Choroidal Melanocytosis
Ophthalmic Surgery, Lasers & Imaging Retina
|March 21, 2019
Summary
This study describes a rare case of bilateral isolated choroidal melanocytosis in an annular pattern. This unique presentation of peripheral retinal hyperpigmentation requires further investigation for malignant potential.
Area of Science:
- Ophthalmology
- Medical Case Reports
- Pigmentary Disorders
Background:
- Choroidal melanocytosis is a rare condition characterized by increased melanin in the choroid.
- Isolated forms, particularly in an annular pattern, are exceptionally uncommon.
- Understanding the presentation and potential risks is crucial for patient management.
Observation:
- A 44-year-old woman presented with asymptomatic bilateral choroidal hyperpigmentation.
- The hyperpigmentation was observed in an annular pattern, spanning 12 clock hours of the peripheral retina.
- No other signs of uveal, scleral, or cutaneous melanocytosis were present.
Findings:
- Optical coherence tomography (OCT) revealed no choroidal thickening or subretinal fluid.
- The diagnosis of bilateral isolated choroidal melanocytosis was established based on clinical presentation.
- This specific annular pattern has not been previously documented in medical literature.
Implications:
- This case highlights a novel presentation of choroidal melanocytosis.
- Long-term follow-up is essential to ascertain the potential for malignant transformation.
- Further research into similar cases may refine diagnostic criteria and prognostic indicators.

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

01:20Overview Of Cell Separation And Isolation
7.5K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

01:19Cyclic Processes And Isolated Systems
3.5K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...

01:12Reduced Mass Coordinates: Isolated Two-body Problem
2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...
