Summary
Lichen nitidus is a rare skin condition presenting as small, shiny papules, often in young people. While typically benign and self-resolving, understanding its features aids dermatologists in management.
Area of Science:
- Dermatology
- Immunodermatology
Background:
- Lichen nitidus (LN) is a rare inflammatory dermatosis.
- Its exact cause is unknown, but immune system involvement is suspected.
- It typically manifests as small, shiny, flat-topped papules, often on the trunk and limbs.
Purpose of the Study:
- To review the clinical, histological, and dermoscopic features of Lichen nitidus.
- To discuss variants and associated systemic conditions.
- To provide management guidance for dermatologists.
Main Methods:
- Literature review of Lichen nitidus.
- Analysis of clinical presentations.
- Histopathological and dermoscopic feature examination.
Main Results:
- Lichen nitidus presents with characteristic papules, often asymptomatic.
- Histopathology shows a distinct "claw clutching a ball" pattern.
- Spontaneous resolution occurs, but persistent cases may need topical treatment.
Conclusions:
- Lichen nitidus is a distinct dermatosis with specific diagnostic criteria.
- Awareness of its features, variants, and associated conditions is crucial for effective management.
- Dermatologists can utilize this review for improved patient care.

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

01:27The Periodic Table and Organismal Elements
18.4K
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

2.1K
Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

01:19Acid Mine Drainage
112
Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten...
