Introduction: The term "atypical melanocytic nevus" (AMN) is used as a synonym for dysplastic nevus (DN) in clinical practice. Although the criteria for diagnosis of AMN/DN by the Agency for Research on Cancer helps to differentiate AMN/DN from common acquired nevi, they do not have high degrees of specificity, as they are similar to those used for the diagnosis of melanoma., Objectives: In this retrospective study we evaluated the correlation and diagnostic concordance of dermoscopy, confocal microscopy, and histological examination in 50 AMN., Methods: A graded scale was used to compare histological examination with dermoscopy and confocal microscopy. Low magnification histological images of only the central part of lesions were examined. This allowed histological diagnoses based almost exclusively on architectural criteria instead of simultaneously architectural and cytological, as in the global histological examination., Results: Our data demonstrate that the diagnostic accuracy of dermoscopy and confocal microscopy diagnosis of the clinical aspects of AMN/DN as nevi or melanomas tends to be equivalent, being fair for nevi and excellent for melanomas. The total percentage of AMN suggested that the accuracy of confocal microscopy in the diagnosis of melanoma (86.7%) is greater than that of dermoscopy (73.3%)., Conclusions: This study demonstrated that diagnostic assessments of AMN/DN by dermoscopy and confocal microscopy are accurate and often coincide with those of histological examination and that their combined use helps to better manage and monitor these patients by facilitating early detection of melanomas and reducing unnecessary excisions of benign melanocytic lesions.

A 56-year-old woman presented to the emergency to be department with diarrhea, asthenia, cough, and dysgeusia. The patient had chronic obstructive pulmonary disease (COPD) and was found infected with coronavirus disease 2019 (COVID-19). On physical examination, a small basal cell carcinoma (BCC) lesion was identified on her scalp; however, following the administration of noninvasive ventilation, the appearance of both macroscopic and microscopic BCC worsened dramatically. Our findings point to positive pressure noninvasive ventilation used to treat COVID-19 associated with COPD as a possible causative agent for the progression of cutaneous BCC.

Introduction: The aim of this article is to summarize published information on systemic infective complications of tattoos to gain an update of the current picture., Methods: A literature search was performed in PubMed database (2009-2019), and compared with a search without year restriction. Eligibility criteria were studies on systemic tattoo-related infections, including case reports, case series, outbreak investigations, reviews, and systematic reviews., Results: We identified 17 manuscripts with systemic infections between 2009 and 2019, with one reported fatality. In contrast to the historical records, no reports of systemic tuberculosis, syphilis or viral (hepatitis or HIV) infections were reported within the study period. A few sporadic cases or Mycobacterium leprae (India) or regional lymphadenopathy associated with skin lesions in non-tuberculosis mycobacteria were identified. Persistent fever with rigour was common in bacterial bloodstream infections. One episode of staphylococcal toxic shock syndrome and several episodes of septic shock were reported, associated with cellulitis or necrotizing fasciitis within two weeks of the procedure, predominantly caused by pyogenic bacteria (S. aureus or streptococcus). Identification of lung or systemic embolisms in the absence of local symptoms, was indicative of (right or left) infective endocarditis., Conclusions: Bacterial bloodstream infections should be considered in subjects developing fever and rigour after tattoos, regardless of local symptoms. A shift in causative organisms has been documented, when comparing with historical reports. NTM are emerging organisms causing lymphadenopathy. Strict hygiene conditions are essential when performing a tattoo., (Copyright © 2021 Elsevier España, S.L.U. All rights reserved.)

The new virus called severe acute respiratory syndrome coronavirus 2 (SARSCov-2) causing Coronavirus disease 2019 (COVID-19) has spread quickly in several countries and it has become pandemic. Different types of clinical manifestations are attributed to this infection. Some mechanisms related to the infection regarding the immune response are not still elucidated. Herein we reported a case of a 66-years-old patient affected by myelodysplasia who was referred to our hospital because of clinical and radiological manifestations of viral pneumonia. The clinical course has become complicated due to bacterial secondary over-infection by Pseudomonas aeruginosa during stay in internal medicine unit whilst a persistent positive oral and naso-pharyngeal swab test was reported up to 100 days of admission. The patient had a fast clinical and radiological worsening that led her to be admitted to an intensive care unit. Despite intubation and mechanical ventilation she died in a few days., (Copyright © 2021 Elsevier B.V. All rights reserved.)

COVID-19 presents with a wide range of clinical neurological manifestations. It has been recognized that SARS-CoV-2 infection affects both the central and peripheral nervous system, leading to smell and taste disturbances; acute ischemic and hemorrhagic cerebrovascular disease; encephalopathies and seizures; and causes most surviving patients to have long lasting neurological symptoms. Despite this, typical neuropathological features associated with the infection have still not been identified. Studies of post-mortem examinations of the cerebral cortex are obtained with difficulty due to laboratory safety concerns. In addition, they represent cases with different neurological symptoms, age or comorbidities, thus a larger number of brain autoptic data from multiple institutions would be crucial. Histopathological findings described here are aimed to increase the current knowledge on neuropathology of COVID-19 patients. We report post-mortem neuropathological findings of ten COVID-19 patients. A wide range of neuropathological lesions were seen. The cerebral cortex of all patients showed vascular changes, hyperemia of the meninges and perivascular inflammation in the cerebral parenchyma with hypoxic neuronal injury. Perivascular lymphocytic inflammation of predominantly CD8-positive T cells mixed with CD68-positive macrophages, targeting the disrupted vascular wall in the cerebral cortex, cerebellum and pons were seen. Our findings support recent reports highlighting a role of microvascular injury in COVID-19 neurological manifestations.

The practice of tattooing dates back to 5000 years ago and is currently constantly growing. The most common pigment associated with tattoo complications is the red one. Another pigment, which could be associated with adverse reactions, even if less frequently than red, is blue. Traditionally, blue pigment contains cobalt, which causes allergic reactions. Here, we report a case of blue pigment granulomatous reaction in a 37-year-old male patient., (© 2020 Wiley Periodicals LLC.)

A 33-year-old woman presented with recurring pruritic, erythematous papules around the mouth and on the hands, of 1.5 years' duration. These flares typically began several days before her menstrual cycle and persisted for approximately 1 week. Physical examination revealed urticarial plaques on the neck. Due to the nature of the eruption, which corresponded with her menstrual cycle, a diagnosis of autoimmune progesterone urticaria was considered and workup pursued.

A 27-year-old woman with systemic lupus erythematosus since childhood and treated with immunosuppressive therapy for many years was referred to our clinic for the presence of widespread condylomatosis and mollusca contagiosum localized in the genital area. These lesions appeared 4 years before and had been treated with both surgery and topical immunomodulation therapy without resolution. The patient stated that she had two sexual partners in that period, who showed no skin lesions. Cutaneous examination showed about 30 to 40 molluscoid lesions of 0.5 cm to 2 cm in diameter and widespread cauliflower-like condyloma acuminata (Figure) spread on the vulvovaginal and perianal region without any symptoms. At the time of observation, she was under treatment with corticosteroids and mycophenolate mofetil.
