まとめ
皮膚顕微鏡による高周波超音波 (DA-HFUS) は,血管腫やブルーネビのような良性皮膚病変を識別するのに役立ちます. この非侵襲的イメージング技術は,正確な診断のために皮膚顕微鏡に補完的な構造情報を提供します.
科学分野:
- 皮膚科
- 医療用イメージング
- 病理学について
背景:
- 血管腫とブルーネビはよく見られる良性皮膚病変です.
- これらの病変は臨床的には メラノーマのような悪性疾患に似ています
- 適切な患者管理には正確な差異化が不可欠です.
研究 の 目的:
- 血管腫とブルーネビの特徴化における皮膚検査補助高周波超音波 (DA-HFUS) の有用性を評価する.
- 皮膚検査と並行して DA-HFUS の補完的な役割を評価する.
- 良性皮膚病変の非侵襲的な診断能力を向上させるため
主な方法:
- 診断された血管腫 (2) とブルーネヴィ (3) の5人の患者を対象としたケース研究.
- 手持ちの33MHz Dermus SkinScannerをDA-HFUSに統合した光学ガイドを使用しました.
- 高周波超音波画像の特徴と相関する皮膚検査結果
主要な成果:
- 皮膚検査では 青いネビは正規で スレートブルー/茶色の病変と 血管腫は 欠陥のある青い紫色のパプルを示しました
- 超音波検査で 青いネヴィは 潜在的に高音質の 線維の焦点を持つ 低音質の病変だと判明した
- 血管腫は血管と繊維の成分を反映した異質なエコーテクスチャを示し,繊維性ブルーネビは皮膚の深い拡張を示した.
- DA-HFUSでは,皮膚検査では見えない,繊維性ブルーネビのハイパーエコージェニックコラムのような構造的な詳細が特定されました.
結論:
- DA-HFUSは,良性色素の病変を特徴付けるための皮膚検査に役立つ補足情報を提供します.
- 結合したアプローチは,血管腫と青いネビの区別のための非侵襲的な診断の精度を高めます.
- DA-HFUSは,これらの一般的な皮膚病変の構造的評価を支援し,誤診を減らす可能性があります.

Changes in Skin Color: Clinical Perspectives
2.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Skin Cancer
4.5K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Reticular Dermis
2.9K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Pigmentation
2.6K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
