Dermatologists are often faced with the challenge of patients presenting with non specific symptoms such as itching and or erythema. These symptoms may be attributed to a number of diseases, many of which are trivial, and others even life-threatening. In order to establish the correct diagnosis, dermatologists must rely on good diagnostic tools and knowledge. Read More

Sebaceous carcinomas are rare but potentially fatal malignant adenocarcinomas with varying degrees of sebaceous differentiation. Several dermoscopic findings of extraocular sebaceous carcinomas have been reported; however, there are no previous reports of ocular sebaceous carcinomas detected using dermoscopy. We present a case of ocular sebaceous carcinomas showing specific findings from dermoscopy, and describe the common dermoscopic characteristics. Read More

Palmar syphiloderm is one of the most common presentations of secondary syphilis and its recognition is of utmost importance in order to promptly identify such a disease and initiate appropriate workup/management. However, the differential diagnosis with palmar papular psoriasis often poses some difficulties, with consequent possible diagnostic errors/delays and prescription of improper therapies. In this report, we underline the role of dermoscopy as a supportive tool to facilitate the non-invasive recognition of palmar syphiloderm and its distinction from palmar papular psoriasis. Read More

Recently, intensive research on photoacoustic (PA) imaging has been conducted to accelerate the development of dermoscopy of the human skin. In this Letter, we first developed a PA dermoscope equipped with a waterless coupling and impedance matching opto-sono probe to achieve quantitative, high-resolution, and high-contrast imaging of the human skin. Compared with the commonly used liquid-coupled PA probes, the human-skin-adapted probe can facilitate implementation in the clinical setting. Read More

There have been few studies investigating diagnostic accuracy between plastic surgeons, or comparing this with dermatologists. Use of dermoscopy by dermatologists has widened the diagnostic gap between dermatologists and plastic surgeons, with plastic surgery lagging behind dermatology in learning this technique. Consequently, plastic surgeons are likely to have a lower threshold for performing a diagnostic or excisional biopsy than dermatologists, leading to a higher rate of intervention for lesions that could otherwise be managed non-surgically.

The treatment of pigmented lesions includes several approaches depending on the nature of the cutaneous lesion to be treated. When considering melanocytic lesions, a balance between therapeutic aspects and cosmetic concerns for aesthetic sites have to be taken into account, with particular attention for the differential diagnosis between benign and malignant.(1-3) In particular, the increasing awareness for good cosmetic results lead to the development of less invasive techniques, although they hamper the histological assessment, which is the gold standard for the diagnosis of melanocytic lesions.

Nail dermoscopy was initially used only in the assessment of nail pigmentation, but now it is widely utilized for the evaluation of many nail disorders. In daily practice, dermoscopy may confirm clinical diagnoses and guides in the management of nail diseases and treatments, permitting a better visualization of symptoms. Dry dermoscopy is required for evaluation of the nail plate surface, while gel as an interface is necessary for assessment of nail pigmentation and onycholysis, as well as for the evaluation of the distal nail margin.
