A peristomal plaque of sudden occurrence.
Koebner phenomenon regards the formation of a psoriatic lesion after a trauma, including tattoo, insect bite or other injuries. Although this manifestation is not specific for psoriasis, physicians should be aware because early recognition may be helpful in making the diagnosis when present
Drug intake and actinic keratosis: A case-control study
Background: Actinic keratosis (AK) is a form of premalignant keratinocyte dysplasia. Recently, the ABSTRACT role of photosensitizing drugs in the development of AK has been postulated. Objective: This study evaluated a possible association between the use of photosensitizing drugs and the development of AK. A secondary aim was to identify a possible association between any medication other than those primarily examined and AK. Methods: A single-center, case-control study assessed the cumulative drug exposure of 90 patients with AK and 90 controls visiting a dermatology service for other skin ailments. Before the visit, patients were interviewed to collect data on daily therapy and the lag-time of discontinued drugs within the last 2 years, and to record the drug's active ingredient, dosage, and duration of therapy. In addition, sociodemographic characteristics including age, sex, educational level, skin phototype, and cumulative sun exposure habits were gathered. Results: By logistic regression, exposures to angiotensin II receptor blockers (ARBs) and antiplatelet agents were identified as independent risk factors for the development of AK. ARB intake was associated with AK only at high exposure (OR = 13.6; 95% CI, 2.0-93.8). The use of antiplatelet drugs was borderline, yet not significant, at low exposure (OR = 3.31; 95% CI, 0.86-12.7), but increased in a dose-dependent manner. The strongest correlation was found at the highest cumulative dose (>1100 dose unit-years (OR = 4.38; 95% CI, 1.16-16.6). Conclusions: High exposure to ARBs and antiplatelet agents may promote AK carcinogenesis in at-risk patients
Should SARS-CoV-2 influence immunosuppressive therapy for autoimmune blistering diseases?
Cauliflower-like exophytic mass on the skin: polypoid melanoma. Clinical, dermoscopic, and histologic features
Polypoid melanoma is a variant of nodular melanoma, whose poor prognosis depends on its thickness and the presence of ulceration at the time of diagnosis. The authors report two cases of polypoid melanoma, presenting as broad, cauliflower-like, polypoid masses. Dermoscopy was characterized by a multicolored pattern, atypical polymorphic vessels, and the fiber sign. Clinical and dermoscopic features can help to diagnose polypoid melanoma and exclude other possible differential diagnoses. However, histology remains mandatory to confirm the diagnostic suspicion
A Double Case of Nail-Patella Syndrome in the Same Family: The Importance of Nail Changes as Diagnostic Clues for Renal Involvement.
Nail diseases are rarely given significant importance in general consultation and their specific examination is often neglected, while localization to the nails could be an initial sign of a syndrome or a systemic disorder. Although rarely, nail alterations could be a sign of a systemic disorder, in which a prompt observation is crucial for an early diagnosis. We describe the case of an elderly woman with a long history of nail dystrophy, previously labelled as nail fragility. On enquiry, similar nail changes were discovered to have affected the patient's son, who was visited the following week. Diagnosis of the Nail-Patella Syndrome (NPS) was suspected on the basis of nail alterations in both patients and confirmed by complementary radiographic examination. Screening for severe renal complications, which could have negatively affected the prognosis and have led to end-stage renal disease, followed. The prompt diagnosis of NPS and the associated diseases are mandatory for a correct management of these patients
The Role of Trichoscopy in Keratosis Follicularis Spinulosa Decalvans: Case Report and Review of the Literature
Keratosis follicularis spinulosa decalvans (KFSD) is a rare, X-linked, hereditary disorder of keratinization, characterized by skin involvement and progressive scarring alopecia of scalp, eyebrows, and eyelashes. The diagnosis is helped by the particular clinical features, but pathology is mandatory. Case Presentation: We described a case of a female patient referred to the outpatient's hair consultation of our department, in which we performed trichoscopy as a very useful tool for the diagnosis, followed by pathology that confirmed KFSD. Conclusion: In our article, we underlined the importance of trichoscopy for the diagnosis of this hair disease, with also a review of the literature on diagnosis and treatment
Topical zinc oxide: an effective treatment option for erosive pustular dermatosis of the leg
Contact dermatitis due to masks and respirators during COVID-19 pandemic: what we should know and what we should do.
Given the current lack of a therapeutic vaccine for coronavirus disease 2019 (COVID\u201019), preventive measures including mask wearing are crucial in slowing the transmission of cases. However, prolonged wearing of protective respirators, medical and fabric masks can easily generate excessive sweating, moisture and friction. Closed and warm environments heighten the skin's permeability and sensitivity to physical or chemical irritants, leading to chronic cumulative irritant contact dermatitis or, rarely, even allergic contact dermatitis. Although not representing a life\u2010threatening condition, contact dermatitis can have a significant impact on emergency management, as it is potentially able to reduce work performance and create emotional discomfort due to the involvement of evident body areas. To minimize the skin breakdown, adherence to standards on wearing protective and safe equipments and avoidance of overprotection should be performed. At the same time, some measures of skin care are recommended. Here, we offer some tips on how to prevent and manage contact dermatitis due to masks not only in health care workers, but also in the general population during this COVID\u201019 outbreak
