Strutton et al.in 1996 and then in Galaria et al. in 2000 reported cases with violaceous papulonodules on the dorsal surfaces of the hands with histopathological findings of a neutrophilic dermatosis in association with leukocytoclasia, but clinically and histologically without true vasculitis findings. Eventually, they proposed the term NDDH for these lesions (1,2). A 46-year-old man was referred to our outpatient dermatology clinic with a painful ulcerative lesion on the dorsal side of the left hand that had been present for one year. Initially, the lesion had appeared as a small purulent papule, which gradually extended to a large ulcer. The patient underwent frequent referrals to several physicians and had taken a variety of topical and systemic antibiotics, meglumine antimoniate (Glucantime), and amphotericin with the clinical diagnosis of cutaneous bacterial or fungal infections, or leishmaniasis. All of these therapeutic regimes were ineffective in eradicating the lesion. Given the history, he denied any trauma to the site of lesion; he also did not report any similar lesions in his family. The physical examination revealed an extensive tender ulcer of 4×7 cm2 in size, with a shallow violaceous border superimposed on an edematous region on the dorsal side of the left hand. Atrophic scars resulting from old similar lesions were visible on the dorsal aspects of the 3rd and 4th proximal and middle metacarpal joints (Figure 1). The examination of the other parts of the body was unremarkable. Laboratory tests showed an impaired white blood cell count and their differentiation, including leukocytosis (white blood cell count of 16.12/mm3) with neutrophilia (neutrophil percent at 65.9%). Additionally, altered liver function tests were remarkable for high serum levels of AST (SGOT) (105 IU/L) and ALT(SGPT) (355 IU/L), while the total bilirubin and alkaline phosphatase were within normal limits. Hemoglobin levels (13.90 g/dL) and platelet count (272/mm3) were within normal range. The other laboratory tests, including serological tests for fasting blood sugar, hemoglobin A1c, creatinine, BUN, and an immunoassay for ruling out vasculitis lesions (anti-MPO (P-ANCA) and anti-PR3 (C-ANCA)) revealed no remarkable results. An erythrocyte sedimentation rate of 16 mm/h was reported. A biopsy was performed. Histologic features demonstrated a dense, diffuse dermal infiltrate comprised almost entirely of neutrophils. The epidermis was slightly acanthotic and showed small foci of spongiosis, but the inflammatory infiltrate remained largely in the dermis. Sheets of neutrophils were present, admixed with karyorrhectic debris. The infiltrate did not appear to be peri-vascular, and most vessels that could be observed clearly appeared to be undamaged. However, some vessels appeared to show some neutrophils infiltrating vessel walls (Figures","PeriodicalId":94367,"journal":{"name":"Acta dermatovenerologica Croatica : ADC","volume":"31 3","pages":"148-50"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140029929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Risk factors include chronic sun exposure and immunosuppression (1). MCC is associated with frequent recurrences and a high metastatic potential and mortality rate (1). It is the second most common cause of skin-cancer-related death after melanoma. At primary diagnosis with an apparent cutaneous tumor, loco-regional metastases are present in up to 30% of patients, and 6-12% have distant metastatic disease (2-3). Up to 5% of cases present with unknown primary origin (4). Five-year overall survival for patients with advanced or metastatic disease is 13-18% (4). We report two cases of MCC presenting without primary cutaneous involvement; first at an unusual location in the adipose tissue of the right breast, and the second one with only a clinically positive left inguinal lymph node. In October 2018, a 78-year-old woman presented with a 15-week history of a painless solitary mass in the upper outer quadrant (UOQ) of the right breast with no visible cutaneous involvement. Her medical history included hypertension, dyslipidemia, and plaque psoriasis. She underwent ultrasound guided biopsy, and histopathology confirmed the diagnosis of metastatic MCC (mMCC). Positron emission tomography/computed tomography (PET/CT) scans showed increased standardized uptake values in the mass in the UOQ and an additional mass in the lower inner quadrant (Figure 1A). The patient underwent mastectomy and lymph node dissection of the right axilla. Histopathology confirmed mMCC and negative axillary lymph nodes. Regular follow-up (clinical examination, PET/CT scan, ultrasound, mammography) every 6 months revealed no disease recurrence during this 4-year period (Figure 1B). In September 2021, a 66-year-old man was referred to our Clinic with clinically detectable painful left inguinal lymphadenopathy. Excisional biopsy was performed, and histopathology confirmed the diagnosis of mMCC (Figure 2). After an extensive clinical and imaging evaluation (PET/CT scan), which confirmed disseminated disease (Figure 3A), initial treatment with the programmed cell death ligand 1 inhibitor (anti PD-L1) avelumab was proposed.

Pemphigus vulgaris is a rare mucocutaneous autoimmune disease with autoantibodies against desmosomal desmoglein-1 and desmoglein-3, resulting in acantholysis and blister formation. This epithelial barrier defect increases susceptibility to infections, which may lead to relapses (2). Additionally, therapy-associated immunosuppression can lead to severe infections. Corticosteroids are the mainstay therapy. For moderate and severe pemphigus, rituximab is recommended in first-line treatment along with other immunosuppressants, and it may also be added in refractory cases. It is a monoclonal antibody against CD20 with long-lasting B-cell depletion potency. Recovery of B-cell function may last from one to seven years. Consequently, patients receiving rituximab cannot produce enough COVID-19 specific plasma cells, leading to a severe course of COVID-19 (2). Shashidi-Dadras et al. reported five mild COVID-19 cases among 167 patients with pemphigus who had received rituximab one to five years earlier. The authors presumed rituximab use within five years increases COVID-19 susceptibility regardless the number of courses received (3). Among 48 patients with pemphigus treated with rituximab within five years, Uzuncakmak et al. reported one mild case of COVID-19 (in a patient who had received a single course seven months earlier) (4). In another study, high titers of SARS-CoV-2 antibodies and high counts of antibody-secreting cells were associated with severe COVID-19 (5), which may be the consequence of antibody-dependent enhancement (6). Mahmoudi et al. concluded that B-cells may not be necessary for recovery in COVID-19, but they may protect from reinfection (7). Considering these data, rituximab should be postponed during the pandemic (8). In exceptional cases, it may be applied with careful consideration of the risk-benefit ratio (2,4). Patients should be monitored for signs of COVID-19 before and during treatment. A 63-year-old woman with pemphigus vulgaris presented at our department with widespread skin lesions. Comorbidities included hypertension, hypothyroidism, and glaucoma. Diagnosis was established based on histology and direct and indirect immunofluorescent microscopy results. Both desmoglein-1 and desmoglein-3 autoantibodies were detectable by ELISA. The patient was initially treated with low-dose systemic methylprednisolone (8 mg/day), because glaucoma contraindicated a higher dose. Azathioprine was subsequently started (gradually increased from 0.6 to 2.5 mg/kg/day). Continuous mucocutaneous progression 4 weeks later led to the decision to add rituximab therapy.

The benign nature of the \"Spitz nevus\" has since been clarified, but the debate regarding Spitzoidtumors (STs) is still ongoing. Spitzoid tumors encompass a wide spectrum of cutaneous lesions ranging from benign Spitz nevus (SN) to Spitzoid melanoma (SM), the latter displaying capacity for widespread metastasis and a potentially lethal outcome (2). The term atypical Spitz tumors (ASTs) refers to melanocytic tumors exhibiting the morphological features of SN, as well as some features associated with malignancy, but not sufficient to classify them as SMs. Currently, histopathology is the gold standard for the diagnosis of STs and cutaneous MM. However, the differential diagnosis between benign and malignant melanocytic lesions with spitzoid features remains challenging (3-6). In order to facilitate the work of clinicians and pathologists, we attempted a comparative clinical and demographic study comparing ASTs and MMs of patients referred to two Italian institutes. Patient data were obtained from two different Italian dermatological centers (Melanoma Registry of the Instituto Dermopaticodell'Immacolata IDI-IRCCS Rome, Lazio and the Skin Cancer Unit of Dermatology, Hospital Sant'Orsola-Malpighi, University of Bologna), from January 2007 to December 2017. Histological reports presenting pre-operative queries of both \"atypical Spitz nevi\" or \"malignant melanoma\" and a final diagnosis confirming one of the queries were included in the study. The chi-square test or Mann-Whitney U-test were applied to analyze differences between the groups for categorical variables such as sex, diagnosis, and continuous variables (age). The \"anatomic site\" variable was classified into three categories as follows: the limbs, trunk, and head/neck. A multivariate binary logistic model was used to investigate if the anatomic site was an independent predictor of MM. Age and sex were considered confounding factors. A total of 504 patients (51.8% men; 48.2% women) met the inclusion study criteria (mean age 52 years, SD = 22.8) (Table 1). 373 were cases of MM and 131 were cases of AST. Mean age of MM cases and AST were 61.2 years old (SD = 17.6) and 25.8 years old (SD = 13.8), respectively. Subjects with MM were predominantly men (58.2% versus 33.6%) (P<0.0001) and older (median age 62 years versus 25 years) (P=0.0001) than subjects with AST. The most frequent anatomic site for MM was the trunk (39.7 %), while the lower limb was the most frequent anatomic site for AST (48.1 %) (P<0.0001). Table 2 shows the multivariable analysis used to assess if anatomic site was an independent predictor of cutaneous melanoma. Multivariate analysis confirmed an increased risk for MM in comparison with AST for both localization on the trunk (OR:2.78; 95 %CI: 1.74-4.45) (P<0.0001) and head/neck (OR:3.20; 95% CI: 1.60-6.38) (P=0.0001).

A Case of Noonan Syndrome and Kyrle Disease: Casualty or Causality? 一例努南综合征和柯尔氏症病例:偶然还是必然?

Clinically, there were multiple umbilicated papules with a hyperkeratotic central plug, localized on the upper and lower limbs (Figure 1, a-b). The patient had no personal history of diabetes mellitus or chronic renal failure, but suffered from hypertrophic cardiomyopathy. Blood tests showed no abnormalities. On histological examination of a skin lesion, an ectatic hair follicle with a hyperkeratotic ostium was observed with fragments of hair, inflammatory cells, and epidermal perforation. A final diagnosis of Kyrle disease (KD) was established. The patient underwent narrowband UVB (NB-UVB) phototherapy with residual atrophic scars (Figure 1, c-d), but with a complete and long-lasting resolution of symptoms. KD belongs to perforating dermatoses (PD), a heterogeneous group of skin diseases characterized by the transepidermal elimination of dermal components. Despite the classification of PD still being under debate, four primary forms are traditionally recognized: reactive perforating collagenosis, elastosis perforans serpiginosum, perforating folliculitis, and KD (1). The typical skin manifestation of KD is an eruption of dome-shaped papules and nodules, with a whitish central keratotic plug, mainly localized on the extremities and the buttocks. Described by Kyrle in 1916, KD is frequently associated with systemic diseases, especially chronic renal failure and diabetes mellitus. Other associated conditions include chronic hepatic disease, internal malignancies, and congestive heart disease (1). Despite the absence of a consensus, the control of the underlying disease remains the first therapeutic target. Both topical (keratolytics, retinoids, and corticosteroids) and systemic treatments (corticosteroids, retinoids, antibiotics, and phototherapy) have been reported to control skin manifestations (2). In our experience, NB-UVB is an effective option as first-line therapy in case of diffuse lesions, both in KD and in other PD (3). NS is a relatively common RASopathy, a heterogenous group of genetic diseases characterized by a defect of the Ras-mitogen-activated protein kinase (Ras-MAPK) pathway, with an estimated prevalence of 1/1000-2500. PTPN11 is the most frequent mutated gene, accounting for 50% of cases, but more than ten genes have been identified as causing NS (4). Classical features include a distinctive facial dysmorphism, short stature, pulmonic stenosis, and other anomalies of different organs. The skin is commonly involved. Keratinization disorders and hair abnormalities such as keratosis pilaris, ulerythema ophryogenes, wavy or curly hair, and scarce scalp hair, are often described. Other cutaneous signs include easy bruising, skin hyperlaxity, multiple lentigines, and café-au-lait spots (5).
