Dermoscopy is a non-invasive in-office method, which enables the diagnosis of many dermatoses and reduces the need for performing biopsies. To date, no systematic review about the diagnostic usability of dermoscopy in psoriasis has been available. The objective of this article is to summarize and critically analyze literature data on the dermoscopy of skin, scalp and nail changes in psoriasis. Read More

We have observed three patients on anticancer therapies presenting with asymmetric acral spared phenomenon and found six identical cases in the literature. All of them had common features, an alteration of the peripheral nerves affecting a limb unilaterally that was spared by a hand-foot syndrome or hand-foot skin reaction. A drug-induced neurotropic effect sounds logical for developing such alterations with specific chemotherapeutic agents (taxanes, cap-ecitabine), while we have not found good explanations concerning the multikinase inhibitor sorafenib nor the topo isomerase inhibitor adriamycin.

Targeted therapies and immunotherapies are associated with a wide range of dermatologic adverse events (dAEs) resulting from common signaling pathways involved in malignant behavior and normal homeostatic functions of the epidermis and dermis. Dermatologic toxicities include damage to the skin, oral mucosa, hair, and nails. Acneiform rash is the most common dAE, observed in 25-85% of patients treated by epidermal growth factor receptor and mitogen-activated protein kinase kinase inhibitors. Read More

Sparfloxacin is an antibiotic in the quinolone group of antibacterial agents, which often induce photosensitive skin reactions, more often phototoxic reactions than photoallergic ones, and sometimes associated photo-onycholysis. We present a case of phototoxic dermatitis with photo-onycholysis in a 38-year-old man probably induced by sparfloxacin, which was prescribed to him along with rifampicin and clofazimine because he was suffering from borderline lepromatous leprosy. He developed exaggerated sunburn-like eruptions mainly on sun-exposed sites along with painful onycholysis of the fingernails. Read More

Retronychia is a recently described disorder caused by ingrowth of the proximal nail plate into the proximal nail fold. It is suspected when there is persistent paronychia, particularly in the setting of trauma. This disease is probably underdiagnosed due to limited knowledge among dermatologists and the presence of incomplete clinical forms. Read More

Squamous cell carcinoma (SCC) of the nail apparatus is a rare malignant tumor that usually originates underneath the nail plate and grows slowly with possible bone invasion. The etiology remains unknown, although a strong association with different conditions, such as high-risk human papillomavirus (HPVs), trauma, or radiation exposure has been demonstrated. Nail SCC is called "the great mimicker nail tumor" because different clinical presentations may coexist, resembling benign or malignant nail lesions. Read More

Psoriasis is the skin disease that most frequently affects the nails. Depending on the very nail structure involved, different clinical nail alterations can be observed. Irritation of the apical matrix results in psoriatic pits, mid-matrix involvement may cause leukonychia, whole matrix affection may lead to red lunulae or severe nail dystrophy, nail bed involvement may cause salmon spots, subungual hyperkeratosis, and splinter hemorrhages, and psoriasis of the distal nail bed and hyponychium causes onycholysis whereas that of the proximal nail fold causes psoriatic paronychia.

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.
