    Majocchi granuloma presenting as a verrucous nodule of the lip.
    Proc (Bayl Univ Med Cent) 2018 Jan 10;31(1):115-116. Epub 2018 Jan 10.
    Center for Clinical Studies, Houston, Texas.
    We present a case of Majocchi granuloma, a deep folliculitis, on the lip of a healthy 41-year-old man. The patient was successfully treated with systemic and topical antifungal medications. Correct diagnosis of this rare condition is needed, since misdiagnosis as an inflammatory dermatitis and treatment using topical corticosteroids can lead to dissemination of the infection. Read More

    Th17/Treg imbalance in hidradentitis suppurativa/acne inversa: the link to hair follicle dissection, obesity, smoking, and autoimmune comorbidities.
    Br J Dermatol 2018 Mar 24. Epub 2018 Mar 24.
    Department of Dermatology and Allergy, Ludwig-Maximilian-University of Munich, Munich, Germany.

Elevated serum levels of interleukin 17 and local increase in the ratio of proinflammatory Th17 cells and antiinflammatory regulatory T cells (Tregs) have been reported. Perifollicular Tregs play a key role for HF stem cell homeostasis and infundibular integrity. Read More

    Cutaneous infections in the mature patient.
    Clin Dermatol 2018 Mar - Apr;36(2):188-196. Epub 2017 Oct 3.
    Sector of Dermatology and Post-Graduation Course in Dermatology, University Hospital and School of Medicine, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil. Electronic address:
    Dermatologists must be familiar with the peculiarities of the micro-organisms that may affect the elderly, in order to optimize the diagnosis and treatment of infections, which may affect their skin, especially because the world population is rapidly aging. It is estimated that there will be 434 million individuals over 80 years of age in 2050. Since the elderly population is rapidly increasing and their infections are usually more severe and different from those observed in younger adults, it leads to a statistical increase of the rates regarding hospitalization and mortality caused by infectious diseases among people over 85 years.

    The presence of occipital hair in the pilonidal sinus cavity-a triple approach to proof.
    Int J Colorectal Dis 2018 May 28;33(5):567-576. Epub 2018 Feb 28.
    Department of Anesthesiology and Pain Therapy, Bern University Hospital Inselspital, University of Bern, Bern, Switzerland.
    Purpose: Hair in the pilonidal sinus is not growing within the sinus cavity, as hair follicles are not present there. Not few pilonidal patients do not have intergluteal hair, which is said to be the causative agent of folliculitis and pilonidal genesis. So, what is the real source of the hair forming the typical pilonidal hair nest?

    Methods: A trifold approach was used: First, axial hair strength testing of pilonidal hair and body hair harvested from head, lower back (glabella sacralis), and cranial third of intergluteal fold. Read More

    Special types of folliculitis which should be differentiated from acne.
    Dermatoendocrinol 2017 27;9(1):e1356519. Epub 2017 Sep 27.
    Department of Dermatology, Beijing Hospital, National Center of Gerontology, Dongdan, Dongcheng District, Beijing, China.
    Because both acne vulgaris and folliculitis can present as inflammatory erythematous papules, pustules or nodules, they are often hard to distinguish. The importance to distinguish between these 2 shall be stressed as their pathogenesis and therapies are different and misdiagnosis or missed diagnosis may lead to improper treatment. We will introduce several special types of folliculitis that should be differentiated from acne to increase our knowledge of the disorders with an acne-like manifestation. Read More

    Hautarzt 2018 Feb;69(2):134-142
    Klinik für Dermatologie, Venerologie und Allergologie, Universität des Saarlandes, Campus Homburg, Homburg, Deutschland.
    Postmenopausal lichen planopilaris (PLPP), also known as fibrosing frontotemporal alopecia Kossard (FFAK), is a not uncommon inflammatory scalp disease affecting approximately 5% of patients at specialized hair centers. The overall incidence of sporadic occurrence is believed to be just under 1% in the older, predominantly female, general population. Since the disease is often undiagnosed, it is statistically likely to be underrepresented. Read More

    Naked Hair Shafts as a Marker of Cicatricial Alopecia.
    Am J Dermatopathol 2017 Dec 28. Epub 2017 Dec 28.
    Departments of Dermatology, and.
    Naked hair shafts (NHS) are free-floating hair shafts devoid of surrounding epithelium, supporting structures, and/or embedded in inflammation that may result from destruction of hair follicles by scarring processes such as inflammation and fibroplasia. Extensive examination of NHS has not been performed in scalp biopsies of alopecia. We retrospectively evaluated 622 scalp biopsies of alopecia [345 cicatricial alopecias (central centrifugal cicatricial alopecia, lichen planopilaris, discoid lupus erythematosus, acne keloidalis nuchae, and folliculitis decalvans] and 277 non-cicatricial alopecias [alopecia areata, androgenic alopecia, telogen effluvium, and psoriatic alopecia)] for the presence of NHS.

    Erosive Pustular Dermatosis of the Scalp with Urate-Like Crystals.
    Case Rep Dermatol Med 2017 8;2017:1536434. Epub 2017 Oct 8.
    Auckland University of Technology, Auckland 1142, New Zealand.
    Follicular urate-like crystals were first described in Necrotizing Infundibular Crystalline Folliculitis (NICF), a rare cutaneous disorder with multiple waxy folliculocentric papules. Similar crystal accumulation may be seen within follicular infundibulae as an incidental finding. We describe a case showing identical crystals occurring within the horn-like crusts of a patient with erosive pustular dermatosis of the scalp (EPDS), a condition which due to its presentation can often be mistaken for nonmelanoma skin cancer.

    Autoimmune Progesterone Dermatitis: A Diagnosis to Consider in a Patient With Cyclical Cutaneous Eruptions.
    J Drugs Dermatol 2017 Oct;16(10):1040-1042
    Autoimmune progesterone dermatitis (APD) is a cyclical cutaneous reaction to progesterone, with symptoms that typically begin 3-10 days before the onset of menstrual flow and end 1-2 days into menses. The symptoms vary in severity from barely visible to anaphylaxis, but most often include an eczematous eruption, erythema multiforme, urticaria, folliculitis, and angioedema.

    Overexpression of NLRP3, NLRC4 and AIM2 inflammasomes and their priming-associated molecules (TLR2, TLR4, Dectin-1, Dectin-2 and NFκB) in Malassezia folliculitis.
    Mycoses 2018 Feb 13;61(2):111-118. Epub 2017 Oct 13.
    Department of Dermatology, Affiliated Hospital of Guangdong Medical University, Zhanjiang, Guangdong, China.
    The activation of NLRP3, NLRC4 and AIM2 inflammasomes is pivotal for innate immunity against some pathogenic fungi, but their role in the pathogenesis of Malassezia folliculitis (MF) remains unclear. The objective of the study was to determine the expression of 4 canonical inflammasomes (NLRP1, NLRP3, NLRC4 and AIM2) and their priming-associated molecules (TLR2, TLR4, Dectin-1, Dectin-2 and NFκB) in MF lesion. Expression of NLRP1, NLRP3, NLRC4, AIM2, caspase-1, IL-1β, TLR2, TLR4, Dectin-1, Dectin-2 and NFκB was detected by immunohistochemistry in skin lesion of 23 MF patients and normal skin of 12 healthy subjects.
