RESUMO

INTRODUCTION: Diagnosis of melanoma can be very difficult because of its phenotypic and histological heterogeneity. Difficult-to-diagnose melanoma can be represented by mucosal melanoma, pink lesions, amelanotic melanoma (amelanotic lentigo maligna, amelanotic acral melanoma, desmoplastic melanoma), melanoma arising on sun-damaged facial skin, and "featureless melanoma". OBJECTIVES: The aim of the study was to improve the identification of featureless melanoma (scoring 0-2 according to the 7-point-checklist) describing the variegated dermoscopic features and their histopathological correlation. METHODS: Study samples included all melanomas excised based on clinical and/or dermoscopic findings in the period between January 2017 and April 2021. Before excisional biopsy, all lesions were recorded by means of digital dermoscopy at the department of Dermatology. Only lesions with a diagnosis of melanoma and a high quality of dermoscopic images were included in this study. After clinical and dermoscopic evaluation of 7-point checklist score, single dermoscopic and histological features were considered for lesions with a score of 2 or lower and a diagnosis of melanoma (corresponding to dermoscopic featureless melanoma). RESULTS: A total of 691 melanomas fulfilled inclusion criteria and were retrieved from the database. The 7-point checklist evaluation identified 19 "negative-featureless" melanoma. The 100% of the lesions with score 1 showed a globular pattern. CONCLUSIONS: Dermoscopy is still the best diagnostic method for melanoma. The 7-point checklist provides a simplification of standard pattern analysis because of the algorithm based on a scoring system and the lower number of features to recognize. In the daily practice it is more comfortable for many clinicians to keep in mind a list of principles that may help in the decision.

RESUMO

Dermatology is a field of medicine where urgent cases occur commonly. However, access to specialized emergency dermatology services is very limited. Following the declaration of the COVID-19 pandemic, the cessation of all elective dermatology visits was widely urged. Accordingly, in Italy, a country severely affected by the pandemic, various measures were applied and the care at university clinics was limited to urgent cases. Here we retrospectively analyzed data of patients who presented at an Italian academic outpatient clinic reserved only for emergency cases. In total, 252 patients (109 males and 143 females) with a mean age of 55.25 ± 20.99 years were cared for at our clinic during a three-month period. We classified 10 patients (4%) as real emergency cases. Pityriasis rosea was diagnosed in three patients. Many patients sought care for skin cancer screening. In 131 patients (52%) dermoscopic skin examinations were performed. In 39 patients (15%), actinic keratosis or nonmelanoma skin cancer was detected, while melanoma was diagnosed in three patients, two of which were proven later as in situ melanoma. About 111 patients (44%) visited our clinic for other, nonurgent skin diseases. Our results imply that many patients felt that their skin problems required immediate attention, even if this could not be justified. Melanoma care may be considered an emergency care for its highly malignant potential and the possibility of rapid spreading. Adequately taken photos with a dermoscope may be readily read without the presence of specialist in the emergency room to prevent unnecessary delay in diagnosing oncologic skin diseases.

RESUMO

Primary immunodeficiencies are rare, inherited diseases, characterized by altered function or absence of immune cells. Among them is leukocyte adhesion deficiency Type I (LAD-I), an autosomal recessive disorder characterized by primary immunodeficiency, caused by mutations in the ITGB2 gene which produces inability of leucocytes to migrate toward the area of inflammation and is associated with recurrent life-threatening bacterial and fungal infections. Pyoderma gangrenosum (PG) is an uncommon noninfectious neutrophilic dermatosis, characterized by recurrent, necrotic ulcers. It is a diagnosis of exclusion and can be challenging and its management is empirical, with local (topical tacrolimus or intralesional triamcinolone) or systemic immunosuppressive therapy (oral or intravenous glucocorticoids, sulfasalazine, especially in cases associated with Crohn's disease, cyclosporine and, recently, anti-tumor necrosis factor drugs such as Infliximab, Etanercept, and Adalimumab). Though skin ulcerations are common, predominant clinical presentation as PG can often mimic other diseases. It is unusual in children even more in LAD-I. Here, we present a Yemenian family with LAD-I from consanguineous relatives. All patients had history of chronic recurrent skin ulcerations without any bleeding tendency, associated with persistent neutrophilia and requiring steroids and antibiotics. There was no history of delayed cord separation and the condition was initially diagnosed as epidermolysis bullosa, but successively as PG. LAD-I should be kept in mind while evaluating patients with PG especially in children with persistent neutrophilia in the absence of other rheumatological disorders. Its diagnosis is extremely important from the management perspective, as treating these patients without adequate antibiotic cover may be fatal, as happened to one of our patient, and these patients often require hematopoietic stem cell transplantation for permanent cure. Therefore, genetic counseling especially in population with high consanguinity is mandatory.

RESUMO

We present the case of a 60-year-old man with unresectable cutaneous squamous cell carcinoma (cSCC) of the sternal area, which was not amenable to radiation therapy. The treatment history of this patient is remarkable as the disease had progressed through all lines of conventional therapy established in the literature. We decided to initiate treatment with epidermal growth factor receptor (EGFR) inhibitor cetuximab and we reassessed the patient after 12 weeks with a whole-body CT scan, documenting stability in the size and radiologic features of the disease. Cetuximab, like all current treatments for advanced cSCC, is administered off-label and proved effective in preventing further progression of disease in our patient.
