Aplasia cutis congenita (ACC) is a rare disease characterized by congenital absence of skin, affecting preferentially the scalp. Diagnosis is made clinically; however, recent studies have shown that dermoscopy can be a useful tool for the diagnosis and differentiation from sebaceous nevus. The clinical findings include a shiny atrophic alopecic patch associated with dermoscopic findings of absent follicular openings, thicker vessels and a distinct collar hypertrichosis. We report 2 cases of alopecia presenting from birth...

Photodynamic therapy (PDT) is a noninvasive treatment that utilizes light treatment along with application of a photosensitizing agent. In dermatology, PDT is commonly used and approved for the treatment of oncological conditions such as actinic keratosis, Bowen disease and superficial basal cell carcinoma. In the last 2 decades however, PDT has also been used for the treatment of several nonneoplastic dermatological diseases. The present review summarizes published data on PDT application in skin appendage disorders...

Lupus erythematosus, especially the discoid form, and lichen planopilaris may be associated and can occur in different topographies (coexistence) or in the same lesion (lupus eythematosus/lichen planus overlap syndrome). Frontal fibrosing alopecia is considered a variant form of lichen planopilaris and is characterized by frontotemporal hairline and eyebrow involvement. Of the association with lupus erythematosus we have only a few descriptions. Hydroxychloroquine and chloroquine diphosphate are antimalarial drugs described as viable treatment options for both diseases, due to an antilymphocytic effect...

IMPORTANCE: Subungual melanoma (SM) is a rare subtype of cutaneous melanoma but carries a worse prognosis than similarly staged cutaneous melanomas. Assessing patient knowledge of melanonychia is integral to early diagnosis of SM. OBJECTIVES: The aim of this paper is to determine patient knowledge of longitudinal melanonychia (LM) and warning signs for SM, frequency of nail self-examinations, and satisfaction of patients with their physician's nail examinations...

Frontal fibrosing alopecia (FFA) is a primary lymphocytic cicatricial alopecia characterized by a progressive band-like recession of the frontotemporal hairline and frequent loss of the eyebrows. It predominantly affects postmenopausal women. Coexistence of FFA and vitiligo is rarely reported in the literature. We retrospectively studied 20 cases diagnosed with FFA in a 14-month period in our Department. Among them, there were 2 cases, a 72-year-old woman and a 48-year-old man, who developed FFA on preexisting vitiligo of the forehead...

Vandetanib therapy is a novel once-daily oral multitargeted tyrosine kinase inhibitor, which is currently used in advanced or metastatic medullary thyroid cancer. Skin toxicities are among the most prevalent adverse events reported with this targeted therapy (e.g. acne-like rash, hand-foot skin reaction, hair changes, and paronychia). In addition, photosensitivity reactions may affect more than one third of treated patients. We report here 2 patients developing photosensitivity reactions with vandetanib therapy, including photoonycholysis...

We report a case of a 5-year-old girl with physical and psychomotor retardation, acquired microcephaly, and history of recurrent infections. Dermoscopic and microscopic hair examination revealed a "road-dividing line"-like pigmentation of hair shafts. The combination of history, clinical findings, and hair examination led to the diagnosis of Griscelli syndrome type II. The picture of "road-dividing line" on hair microscopic and dermoscopic examination is highly characteristic for Griscelli syndrome, and in this framework, dermatologic examination may be of high importance for the diagnosis...

BACKGROUND: Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques have been used in various fields of medical research, including different pathologies of the nails; however, no studies have focused on obtaining high-resolution microscopic images and elemental analysis of disorders caused by synthetic nails and acrylic adhesives. METHODS: Damaged/injured fingernails caused by the use of acrylate glue and synthetic nails were investigated using SEM and EDX methods...

Postfinasteride syndrome (PFS) is a term recently coined to characterize a constellation of reported undesirable side effects described in postmarketing reports and small uncontrolled studies that developed during or after stopping finasteride treatment, and persisted after drug discontinuation. Symptoms included decreased libido, erectile dysfunction, sexual anhedonia, decreased sperm count, gynecomastia, skin changes, cognitive impairment, fatigue, anxiety, depression, and suicidal ideation. The aim of this study is to review the existing medical literature for evidence-based research of permanent sexual dysfunction and mood changes during treatment with 5-alpha-reductase inhibitors including finasteride and dutasteride...

Several countries experience a new epidemic of syphilis, mainly due to the changes in risk behaviors. Dermatologists play an important role in the diagnosis, since cutaneous manifestations are frequent during disease progression. We report a rare case of secondary syphilis with periungual involvement. Syphilis, especially in the secondary form, may present with different clinical features, affecting different organs, and mimicking many diseases. Although nail apparatus lesions are more common in the primary form of the disease, they may also be present in the secondary and tertiary forms...

Trachyonychia is a disorder of the nail unit that most commonly presents with rough, longitudinally ridged nails (opaque trachyonychia) or less frequently, uniform, opalescent nails with pits (shiny trachyonychia). The term trachyonychia refers to 'rough nails.' This article comprehensively reviews the clinical, histologic, and therapeutic aspects of trachyonychia. The authors' preferred evaluation and management strategies of trachyonychia are included.

BACKGROUND: Nail psoriasis is a painful and disfiguring nail disease that often leads to invasive biopsies. Dermoscopy of the hyponychium can be useful in the diagnosis showing twisted coiled vessels. Structural features of nail psoriasis have been described with optical coherence tomography (OCT). OBJECTIVES: To investigate vascular features of nail psoriasis using dynamic OCT. METHODS: This was an observational, prospective, controlled study in which psoriasis patients with psoriatic nail changes and healthy control patients underwent OCT imaging of the distal nail plate and proximal nail fold...

Subungual keratoacanthoma (SUKA) is a rare form of keratoacanthoma, with the majority of the lesions appearing as rapidly growing, painful hyperkeratotic masses located under the distal nail plate of the thumb. In some cases, SUKA causes damage to the underlying bone. The first case presented here was treated by surgical excision alone, and human papilloma virus (HPV) type 6 was detected in the tissue samples. The second case was treated by surgical excision plus curettage; however, HPV was not detected, and tumor cells were not found in the curettage material...

Pierre Halteh, Cynthia Magro, Richard K Scher, Shari R Lipner
Onychopapilloma is a benign tumor of the nail bed and distal matrix and is the most common cause of localized longitudinal erythronychia. Here, we describe a case of onychopapilloma presenting as longitudinal leukonychia of the left 4th fingernail in a 71-year-old female. To date, this is only the ninth described case of onychopapilloma presenting as longitudinal leukonychia. We review the literature on the reported cases and provide evidence that longitudinal leukonychia as the presenting sign for onychopapilloma is becoming increasingly recognized in clinical practice...

REVIEW
Antonella Tosti, Boni E Elewski
INTRODUCTION: Toenail onychomycosis is a common disease in which treatment options are limited and treatment failures and disease recurrence are frequently encountered. It usually requires many months of treatment, and recurrence may occur in more than half of the patients within 1 year or more after the infection has been eradicated. Data on long-term treatment, follow-up and recurrence are limited. OBJECTIVE: Our objective is to interpret these data and recommend practical approaches that should minimize recurrence based on our clinical experience...
