RESUMEN
BACKGROUND: Several studies have shown an association of acne vulgaris with depression and anxiety, but a quantitative review has not yet been conducted. OBJECTIVE: We sought to conduct a systematic review and meta-analysis that elucidates the association of acne vulgaris with depression and anxiety. METHODS: A systematic review and meta-analysis of literature published before October 1, 2019 from the PubMed, PsycINFO, MEDLINE, and Cochrane databases was conducted. We used a metaanalytic approach to perform a random effects analysis comparing individuals with and without acne. Subgroup analyses between studies included age, study setting, and geographic region. RESULTS: Forty-two studies were included. We found a significant association of acne vulgaris with depression (r = 0.22 [95% confidence interval 0.17-0.26, P < .00001]) and anxiety (r = 0.25 [95% confidence interval 0.19-0.31, P < .00001]). Subgroup analyses and comparisons showed moderating influences based on factors including age, study setting, and geographic region. LIMITATIONS: Inconsistency between publications regarding acne and outcome ascertainment, data reporting, and studies with no control group posed considerable barriers to synthesizing all available published literature. CONCLUSIONS: Because of an increased risk for depression and anxiety, clinicians should pursue aggressive treatment of acne and consider psychiatric screening or referrals.

PD-1 is expressed on antigen-stimulated T cells and induces a downstream signaling pathway that works by negative feedback to inhibit T cell proliferation, cytokine release, and cytotoxicity. PD-1 antibodies increase tumor cell killing peripherally and have a role in advanced melanoma treatment. We describe a case of an 84 year old female with stage 4 metastatic melanoma in a trial of the PD-1 inhibitor pembrolizumab who developed multiple keratoacanthomas after several months of treatment. While keratoacanthomas have been reported in patients taking BRAF inhibitors, no such reports exist for those on pembrolizumab, making this the first case report to point out this association for further investigative studies.

BACKGROUND: Precancerous high-grade squamous intraepithelial lesion (HSIL), the current consensus terminology for anogenital squamous cell carcinoma in situ (SCCIS), often presents with distinctive histopathologic findings that may be a function of anatomic site or associated human papillomavirus infection. METHODS: Fifty-six specimens of anogenital HSIL were compared with an equal number of specimens of SCCIS from non-anogenital sites in regard to the presence of parakeratosis, flag sign in the stratum corneum, compact stratum corneum, hypergranulosis, koilocytes, small blue cells, clonal populations of keratinocytes, pagetoid scatter of atypical keratinocytes, clear cell change, glassy red cytoplasm, pigmentation, nuclear/cytoplasmic(N/C) ratio >2/1, nuclear hyperchromasia, pleomorphic nuclei, mitotic figures, abnormal mitotic figures, dyskeratotic keratinocytes, involvement of skin appendages, acantholysis and amyloid deposition. RESULTS: Hypergranulosis, koilocytes, small blue cells, pigmentation, nuclear hyperchromasia, dyskeratotic keratinocytes and amyloid deposition were more frequently noted in anogenital HSIL. Parakeratosis, clear cell change, pleomorphic nuclei, skin appendages involvement and acantholysis were strongly associated with non-anogenital location. There was no significant difference in the incidence of the remaining features. CONCLUSION: The strongest predicators of an anogenital location included hypergranulosis, koilocytes, small blue cells and nuclear hyperchromasia. Pigmentation and amyloid deposition were also strongly associated with an anogenital location.

Dermatologists should be aware that autoantibody formation may occur after the initiation of biologic therapy. This phenomenon has been referred to as immunogenicity and biologic fatigue. Because of this, patients may experience loss of clinical efficacy to a particular drug. To combat this phenomenon, low-dose immunomodulators may be used in hopes of preventing autoantibodies. We review the current literature and provide a basic treatment algorithm for patients with moderate to severe psoriasis.
RESUMEN
INTRODUCTION: Microcystic adnexal carcinoma (MAC) is a rare malignant cutaneous neoplasm presenting as a slow-growing, indurated nodule, papule or plaque. Clinically, the lesion can blend into the surrounding skin, obscuring borders and consequently delaying diagnosis histologically. Surgical and histologic techniques that emphasize examination of all margins may optimize management through early diagnosis and prevention of recurrences. OBJECTIVE: This review aims to assess the current surgical and histology techniques that result in lower rates of tumor recurrence and, consequently, better clinical outcomes. METHODS: A literature search of the PubMed database was conducted to identify studies examining wide local excision (WLE), Mohs micrographic surgery (MMS), radiotherapy (RT) and chemotherapy in the treatment of MAC. RESULTS: WLE had a high likelihood of positive margins and local recurrence. MMS was found to have the lowest recurrence rates. Definitive RT could be considered for elderly patients or those who are poor surgical candidates, as large surgical defects may be required to obtain free margins with either WLE or MMS. Chemotherapy was found to be ineffective. CONCLUSION: Complete margin evaluation with MMS permits complete tumor removal with subsequently low recurrence rate.

Linear immunoglobulin A bullous dermatosis is a rare autoimmune mucocutaneous disorder caused by immunoglobulin A autoantibodies produced against several different antigens in the basement membrane zone. Clinically, it is characterized by tense vesicles or bullae, which on histopathological exam demonstrate subepidermal blister with a predominantly neutrophilic infiltrate. A smooth, linear pattern of immunoglobulin A deposition in the basement membrane zone on direct immunofluorescence is considered the gold standard for establishing a diagnosis. Treatment consists of dapsone or sulfapyridine. The authors report a 60-year-old woman who presented with pruritic erythematous patches and plaques on her trunk, back, and legs without blisters, who was diagnosed with eczema for several months with no response to prior treatments. A biopsy was performed, which was consistent with linear immunoglobulin A bullous dermatosis and later confirmed by direct immunofluorescence studies. The authors present this case to increase awareness of this rare disease, which could manifest in a nonclassical, nonblistering fashion.
RESUMEN
BACKGROUND: Herbal medicines are used by thousands of patients all over the world. However, they can often cause adverse effects. Turmeric, made from the root of Curcuma, longa, is a yellow spice used throughout South Asia for its flavor as well as for its medicinal properties. Curcumin is the main ingredient in turmeric. It is known for downregulating the expression of various proinflammatory cytokines and has been studied for its antiinflammatory mechanism. However, it has also been reported to cause contact dermatitis. Kumkum, a turmeric-based powder applied by Hindu women on their foreheads, has also been found as an allergen. OBJECTIVE: The authors have reviewed the anti-inflammatory properties of curcumin and reports of contact dermatitis to understand the possible harmful effects of this commonly used spice, while also examining its beneficial role in dermatologic conditions. They aim to increase awareness regarding this common herb and its prevalent use not only in South Asia, but also in North America. METHODS: A thorough literature search of the PubMed database was conducted to identify studies that examined the antiinflammatory role of curcumin and its role in contact dermatitis. RESULTS: Eleven studies demonstrate that although curcumin does have antiinflammatory properties, it is an allergen. CONCLUSION: Curcumin has many valuable properties that can be exploited to treat dermatologic conditions. However, patients and dermatologists must be keen of possible allergic reactions. Further studies are needed to completely understand this widely used herb and its efficacy in dermatology.
