Scalp itch is a frequent complaint in the dermatological setting. It is common for the dermatologist to encounter patients with no evident cause of scalp pruritus, making it a distressing situation for both the clinician and the patient. The aim of this paper is to propose a systematic approach to scalp itch, which classifies scalp pruritus into two types: (1) with or (2) without dermatological lesions, and presence or absence of hair loss. Also, it is important to think first about the most common causes and then rule out other, less common etiologies...

Erosive pustular dermatosis (EPD) is a rare condition of the scalp and legs that is marked by crusted erosions or superficial ulcerations that may result in scarring alopecia and chronic wounds. The condition predominantly affects elderly female as compared to male patients. Its pathogenesis remains poorly understood. The majority of the cases in the literature are from the United Kingdom and continental Europe. In this series, we present 8 North American patients with EPD of the scalp, one of whom also had involvement of the legs and another with the involvement of the face...

Onychomadesis occurs when the proximal nail plate becomes unattached to the underlying structures. When only one or a few nails are involved, the cause is usually physical trauma. A 23-year-old female presented with a 4-year history of recurrent onychomadesis involving her bilateral great toes that occurred during the springtime. While recurrent trauma from winter shoes or athletic activities may be a contributing factor, our patient was convinced that wearing tight-fitting socks during winter nights was the primary pathophysiologic process...

First described in 1992, onychomatricoma is a rare, benign, fibroepithelial tumor of the nail matrix with few reported cases in the literature. The tumor predominately affects the fingers of Caucasian women during the 5th decade of life and is typically slow growing and painless. The authors present a unique clinical presentation of a giant onychomatricoma in a darker-skinned 60-year-old South Asian individual who presented with a large dome-shaped nail that was smooth, shiny, and green.

Background: Onychomycosis is a difficult-to-treat fungal infection of the nails. The efficacy of monotherapy is not ideal, and combination therapies provide an alternative that may increase treatment efficacy. Method: A retrospective analysis of data from 91 patients was undertaken. Treatment for toenail onychomycosis occurred between 2014 and 2016 and consisted of combination therapy with oral terbinafine (250 mg/day for 12 weeks) or itraconazole (3 pulses, 400 mg/day for 7 days) + K101 nail solution daily, or K101 nail solution monotherapy...

Introduction: Androgenetic alopecia (AGA) in females is a difficult to treat skin disorder. A novel topical botanical lotion has been approved for its treatment. It acts by increasing Bcl-2, perifollicular Langerhans and mast cells, and perifollicular collagen. The aim of this study was to evaluate the efficacy and safety of this lotion in females. Methods: Forty women with AGA were randomized to apply the active lotion or placebo, twice daily for 24 weeks. Subjects were evaluated at 0, 12, and 24 weeks by clinical examination, photographic documentation, quality of life evaluation (DLQI), and trichogram (anagen to telogen ratio)...

A 37-year-old woman presented with progressive longitudinal erythronychia and onychorrhexis of the toenails. She had a history of sarcoidosis of the lung and nose, which was silent without treatment at the time of presentation. Histopathological examination of a nail matrix biopsy revealed granulomas with palisading histiocytes in the connective tissue and a lymphocytic infiltrate in and around the granulomas without necrosis. Based on the clinical presentation, medical history, and histopathological examination, the diagnosis of nail sarcoidosis was made...

Subungual angiokeratoma is extremely rare. Only 1 case is reported in the literature, presenting as a longitudinal pigmented band on a toenail. We report a case of a subungual angiokeratoma on a fingernail of a 43-year-old woman, clinically mimicking a squamous cell carcinoma. Medical imaging revealed a soft tissue tumor and erosion of the distal phalanx. Although extremely rare, solitary angiokeratomas may arise in the nail apparatus and should be added to the differential diagnosis of subungual warty tumors...

Rodrigo Pirmez, Taynara Barreto, Bruna Duque-Estrada, Danielle C Quintella, Tullia Cuzzi
Background: Frontal fibrosing alopecia (FFA) is considered a variant of lichen planopilaris affecting mainly the frontotemporal hairline. Since the first report in 1994, several other clinical features have been associated with the disease, such as facial papules (FP). Even though FP have been linked to facial vellus hair follicle involvement, how this finding alone could lead to the formation of clinically evident FP in FFA patients had not yet been addressed. Objective: To describe histopathological findings of FP in the context of FFA and to highlight features that may be linked to their clinical formation...

REVIEW
Avner Shemer, Ralph Daniel, Dimitris Rigopoulos, Renata Farhi, Meir Babaev
Wide differences in the cure rates of onychomycosis in various clinical studies can be avoided if we bear in mind some insights that will help us make study results more consistent. We suggest less rigid criteria in defining the cure rate, the inclusion of all toenails in studies, and the exclusion of nails with a history of trauma. Rather than address patients as a homogenous group, regardless of age, we suggest dividing them into age groups. Researchers should not forget inflammatory diseases that can imply changes on the nails and should take into account the duration of onychomycosis, nail changes caused by asymmetry, and the possibility of dermatophytoma...

REVIEW
Aditya K Gupta, Jessie Carviel, Neil H Shear
Onychomycosis is a difficult-to-treat chronic fungal infection of the nail. The chronic nature of onychomycosis, with relevance to current treatment practices, could be attributed to host anergy, development of increased virulence in causal agents (multidrug resistance efflux pump), and biofilms. Biofilms must be disrupted prior to antifungal treatment suggesting the necessity of combination treatment. Once the biofilm has been disrupted, further techniques in addition to antifungal usage are suggested to ensure a positive prognosis including use of antimicrobial photodynamic therapy or low-frequency surface acoustic waves...

Background: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease significantly impacting health-related quality of life (HRQoL). We measured the HRQoL of Finnish HS patients and compared it with that of the general population and psoriasis patients. Methods: Twenty-six diagnosed HS patients completed the 15D HRQoL questionnaire (15D), the Dermatology Life Quality Index (DLQI), and the Beck Depression Inventory-21 (BDI-21). The correlation between the results of these instruments was analyzed and the 15D results were compared with an age-standardized general population and psoriasis patients...

We report the case of a 5-year-old girl born from consanguineous parents, presenting with alopecia universalis since the age of 8 months, without papules or cysts over the scalp or body. The goal of this paper is to emphasize the relevance of histopathology for the early diagnosis of atrichia with papular lesions in children with alopecia universalis, in settings where genetic testing may not be available.

Central centrifugal cicatricial alopecia (CCCA) has become a well-known entity occurring mainly in African-American women, but is rarely encountered in other populations. This report describes a set of identical twin Lumbee Indian women, both developing cicatricial alopecia, with one sister diagnosed with CCCA overlap with lichen planopilaris and the other with CCCA. The Lumbee Tribe is a federally recognized group of Native Americans who reside in North Carolina. Lumbee Indians have shown an increased incidence of several metabolic and neurologic diseases but cicatricial alopecia has never been an identified associated disease of the Lumbee...

While most alopecia areata (AA) cases resolve spontaneously, the more severe types of AA, alopecia totalis (AT) and alopecia universalis (AU), can be highly resistant to therapy. We report on a 33-year-old ultraorthodox Jewish man with an 11-year history of AA that resulted in complete loss of the scalp and body hair 7 years ago. Previous treatments with intralesional and systemic corticosteroids had only partial and temporary effects. The patient was treated with ruxolitinib, 20 mg twice daily, resulting in complete growth of the beard after 4 months of treatment...

We present a case of folliculotropic mycosis fungoides (FMF), a variant of cutaneous T-cell lymphoma which particularly affects hair follicles. FMF can imitate a wide variety of otherwise benign dermatoses, so it poses major diagnostic obstacles both for the dermatologist as well as the dermatopathologist. In our case, in vivo reflectance confocal microscopy (RCM) was very important for guiding the skin biopsy site selection. For this reason, RCM can reduce the number of unsuccessful histopathological examinations and increase the diagnostic accuracy for different skin dermatoses...

Alopecia areata (AA)-like disease is characterized by multifocal patchy hair loss in humans, rodents, dogs, and horses. Remarkable similarities between human and nonhuman AA cases have been reported in terms of clinical presentation, histology, and immune mechanisms of the disease. Canine AA-like lesions most often consist of well-demarcated alopecic patches, frequently but not only involving the face and the head, which extend to the ear pinnae and legs. In some cases, hair loss can have a more generalized distribution...
