RESUMEN

BACKGROUND: Due to progressive ageing of the population, the incidence of facial lentigo maligna (LM) of the face is increasing. Many benign simulators of LM and LMM, known as atypical pigmented facial lesions (aPFLs-pigmented actinic keratosis, solar lentigo, seborrheic keratosis, seborrheic-lichenoid keratosis, atypical nevus) may be found on photodamaged skin. This generates many diagnostic issues and increases the number of biopsies, with a subsequent impact on aesthetic outcome and health insurance costs. OBJECTIVES: Our aim was to develop a risk-scoring classifier-based algorithm to estimate the probability of an aPFL being malignant. A second aim was to compare its diagnostic accuracy with that of dermoscopists so as to define the advantages of using the model in patient management. MATERIALS AND METHODS: A total of 154 dermatologists analysed 1111 aPFLs and their management in a teledermatology setting: They performed pattern analysis, gave an intuitive clinical diagnosis and proposed lesion management options (follow-up/reflectance confocal microscopy/biopsy). Each case was composed of a dermoscopic and/or clinical picture plus metadata (histology, age, sex, location, diameter). The risk-scoring classifier was developed and tested on this dataset and then validated on 86 additional aPFLs. RESULTS: The facial Integrated Dermoscopic Score (iDScore) model consisted of seven dermoscopic variables and three objective parameters (diameter ≥ 8 mm, age ≥ 70 years, male sex); the score ranged from 0 to 16. In the testing set, the facial iDScore-aided diagnosis was more accurate (AUC = 0.79 [IC 95% 0.757-0.843]) than the intuitive diagnosis proposed by dermatologists (average of 43.5%). In the management study, the score model reduced the number of benign lesions sent for biopsies by 41.5% and increased the number of LM/LMM cases sent for reflectance confocal microscopy or biopsy instead of follow-up by 66%. CONCLUSIONS: The facial iDScore can be proposed as a feasible tool for managing patients with aPFLs.

RESUMEN

Various options are available for the reconstruction of full-thickness defects of the nasal ala with different advantages and disadvantages, but none are fully satisfactory. We present the case of a 57- year-old man with a recurrent basal cell carcinoma of the right nasal ala and nearby cheek and upper lip. Tumour clearance was achieved after two stages of 'fresh/frozen' Tübingen technique, resulting in a 2.0×2.0 cm full-thickness defect of the lateral right ala. The wound involved the alar rim, groove and adjacent check and upper lip. Reconstruction was successfully achieved with a nasolabial turnover flap (modified Spear flap) in a single stage. The surgical procedure and subsequent outcomes are illustrated. Our experience shows the effectiveness of the nasolabial turnover flap for a single-stage repair of full-thickness defects of the nasal area and adjacent tissue.

RESUMEN

BACKGROUND: Porocarcinoma (PC) is a rare cutaneous adnexal tumor with a variable metastatic potential. Given the paucity of data, guidelines and specific recommendations for PC are not yet well-established. In this study, we evaluate the disease-specific characteristics and outcome of this rare and often underestimated tumor. MATERIALS AND METHOD: A retrospective study of the epidemiological, clinical, and dermoscopic characteristics among cases of histopathologically diagnosed PC, collected from the database of two skin cancer clinics in Italy (Firenze, Pistoia) from 2000 to 2020, was conducted. RESULTS: Among the 52 patients with 53 tumors, 31 were men (59.6%) and 21 were women (40.4%) with an age range of 49-96 years (median age 82 years). The most common locations were the head/neck region in men (34% in men vs. 17% in women) and the lower limb in women (17% in women vs. 9% in men). Forty-eight cases (91%) underwent local excision. Of these patients, two (4%) experienced local recurrence, and one (2%) developed a second PC on a different anatomical site 1 month after the primary tumor's excision. Lymph node metastases were present in three cases (6%). Two of them have been treated surgically with adjuvant radiotherapy (both are disease-free after a 2-year follow-up period), whereas the third case developed visceral metastases followed by PC-related death. CONCLUSIONS: This study, with 52 patients with 53 tumors covering a follow-up period of more than 5 years, shows a less aggressive behavior of PC with 4% local recurrence, 6% nodal metastases, and 2% mortality.

RESUMEN

BACKGROUND: Atypical Spitz tumours (ASTs) are regarded as an intermediate category distinguished from prototypical Spitz naevus by presenting one or more atypical features and often by an uncertain malignant potential. Clinical and dermoscopic features may play a relevant role in the diagnostic approach. AIM: To evaluate the clinical and dermoscopic features of ASTs, and their evolution over time. METHODS: This was a descriptive, multicentre study of the clinical and dermoscopic characteristics of ASTs. Data on clinical and dermoscopic characteristics, histopathology, local extension, therapy and follow-up, lymph node staging, complete lymph node dissection, and outcome were collected from the databases of four Italian Dermatology Units for the period 2004-2021. RESULTS: The study population consisted of 99 patients (62 female, 37 male) with a histologically confirmed diagnosis of AST, including age at presentation ranged from 2 to 70 years (mean 28.1 years, median 24 years). Of the 99 patients, 29 (29.3%) underwent sentinel lymph node biopsy, which showed evidence of micrometastases in three cases (10.3%); all three patients underwent complete lymph node dissection with no evidence of further metastasis. Considering the whole study population, the clinical outcome was excellent, as all of the patients have no evidence of recurrence or distant metastasis. The follow-up period ranged from 6 to 216 months (mean 81.6 months, median 78 months). In addition, we collected data on the clinical and dermoscopic features of 26 lesions. The most frequent dermoscopic pattern observed was the multicomponent pattern (34.6%), followed by homogeneous (26.9%) and nonspecific (23.2%). In 66.7% of amelanotic ASTs, we observed glomerular (coiled) vessels uniformly distributed within the entire lesion, without asymmetry. CONCLUSION: The results of our study with a long follow-up show no recurrence or distant metastases, confirming the good clinical outcome, even in the case of sentinel lymph node positivity. From a diagnostic point of view, our series identified a typical dermoscopic picture for amelanotic ASTs, with a glomerular vascular pattern throughout the lesion in the absence of other dermoscopic parameters, making the correct diagnosis possible.

RESUMEN

Agminated Spitz nevi are an uncommon entity, and their management is challenging due not only the young age of the patients but also the tumor's uncertain malignant potential and the variability in the dermoscopic and clinical presentation. We report a case of a 6-year-old boy with multiple agminated Spitz nevi on a café au lait macule with different atypical clinical patterns and dermoscopic features.

RESUMEN

BACKGROUND: Lichenoid keratosis is a benign cutaneous lesion exhibiting many clinical faces and different dermoscopic features. OBJECTIVE: This study aims to determine the pattern of different clinical subtypes of lichenoid keratosis and to establish whether there is any correlation between the clinical variants of lichenoid keratosis and their dermoscopic appearance. METHODS: We retrospectively analyzed the medical records and clinical database of patients who had received a histological diagnosis of lichenoid keratosis. Based on the literature review and the clinical-dermoscopic features of lichenoid keratosis, we divided the lesions into 6 clinical subtypes to evaluate potential correlations between clinical and dermoscopic features in all subtypes. RESULTS: Fifty-one lesions were included in this clinical study. Preoperatively, only 1.9% of cases were clinically diagnosed as lichenoid keratosis, and the most common misdiagnosis was basal cell carcinoma (52.9%). We identified 6 subtypes of lichenoid keratosis and their corresponding dermoscopic features and clues. CONCLUSION: Since lichenoid keratosis has no pathognomonic dermoscopic clues and it is commonly misdiagnosed as malignant skin neoplasms, such as basal cell carcinoma and melanoma, improving the knowledge of both clinical and dermoscopic variability of lichenoid keratosis may help dermatologists to reduce unnecessary surgery and to reduce health care spending.

RESUMEN

Observational studies consistently show that melanocytic nevus prevalence increases with age and that phenotypic traits are significantly associated with nevus count in children. An observational study of 1,512 children and adolescents from 2010 to 2013 was conducted. Study dermatologists counted the full body, arm, and facial nevi of each participant. Children and their parents were asked to complete a survey to gather data on personal characteristics, pubertal development, and early-life sun exposure. The main aim of the study was to establish pediatric nevus prevalence and its relationship with age, phenotype, sex, menarche, early-life sun exposure, and sun-protection behaviors. Females had a significantly lower nevus count compared with males, but this sex-related difference was significantly modified by menarche. Sun exposure and sun-protection habits were all significantly associated with nevus count; in particular, children who used sunscreen with a sun-protection factor > 30 had a lower nevus count compared with sun-protection factor ≤ 30 sunscreen users. This study shows that sex, menarche status, and sun-protection practices significantly influence nevus count in this pediatric population.

RESUMEN

Currently, there are no specific clinical and dermoscopic features for diagnosing truly amelanotic plantar melanoma (TAPM). The present study aimed to investigate the dermoscopic features of all clinical variants of TAMPS and to evaluate their histopathological correlations. A retrospective analysis of prospectively collected data was carried out during a 10-year period (2003-2013). We analyzed the clinical data of 1321 patients, who had received a histological diagnosis of melanoma at the Melanoma Unit of the University of Florence. We selected the clinical and dermoscopic images of TAPMs and analyzed the presence of dermoscopic parameters. Incorrect preoperative diagnoses were analyzed to highlight peculiar dermoscopic features of pinkish plantar melanomas, the clinical diagnosis of which is extremely challenging for the dermatologist. Of all 1321 patients, 29 (24%) had TAPMs. Importantly, only 20.7% of patients with TAPMs had a correct preoperative diagnosis of suspicious melanocytic lesion. On the basis of the initial misdiagnosis, TAPMs were categorized as eczema-like, verruca-like, angioma-like lesions. Dermoscopically, all TAPMs showed the presence of a well-defined 'erythematous homogeneous area' with an atypical polymorphous vascular pattern with dotted, globular, and glomerular vessels. Our study highlights a crucial dermoscopic feature of TAPMs, the 'erythematous homogeneous area' that is characteristic of the plantar region, and, to our knowledge and experience, has not been described in nonacral amelanotic melanomas.

RESUMEN

BACKGROUND: Currently, the association between body mass index (BMI) and hormone therapies and Cutaneous Melanoma (CM) development is strongly debated. This study was carried out to assess the association between BMI, hormone therapies, and CM risk. METHODS: The present study is a hospital-based case-control study with 605 consecutive CM patients and 592 controls treated for non-neoplastic conditions at the Department of Dermatology in Florence. The associations of melanoma risk with BMI and hormone therapies were assessed performing unconditional logistic regression to estimate odds ratios (OR) and their 95% confidence intervals, adjusting for potential confounders. RESULTS: We found a significant interaction of BMI with age (P < 0.0001): being overweight significantly increased CM risk among individuals less than 50 years old (OR = 1.85 with 95% CI 1.14-2.94), whereas the association was not significant for individuals over 50 years old (OR = 1.15 with 95% CI 0.77-1.71). For oestrogen therapy, women taking oral contraceptives (OCs)/hormone replacement therapy (HRT) showed a lower CM risk than men (OR = 0.63, 95% CI 0.44-0.89), with risk estimates significantly lower (P < 0.0001) than in non OCs/HRT users, which had an increased risk compared to men (OR = 1.81, 95% CI 1.29-2.53). CONCLUSIONS: Being overweight was significantly associated with CM risk, and this relationship was highly age-conditioned; the second finding was the protective effect of oestrogen therapies for women. Both findings may have a significant impact on melanoma prevention, as the prevalence of obesity and hormone therapy use is increasing worldwide.

RESUMEN

INTRODUCTION: The diagnosis of cutaneous pigmented lesions remains a challenge for both dermatologists and pathologists. Our aim was to determine the diagnostic concordance between the conventional face-to-face diagnosis and the telediagnosis of 10 dermatologists with expertise in dermato-oncology of 10 challenging pigmented lesions. METHODS: Using a store-and-forward teledermatology method, clinical and dermoscopic digital images of all selected lesions were transmitted via e-mail to 10 dermatologists. Dermatologists were called to provide their telediagnoses with a step-by-step approach. When the dermatologists responded with their first clinical telediagnosis, they received a second email that contained dermoscopic images of the 10 cases. Final histopathological diagnosis was considered the gold standard for comparison with face-to-face and teledermatology diagnoses in statistical analysis. RESULTS: Face-to-face results indicated moderate agreement between clinical and histopathological diagnoses (K = 0.6). After the first clinical step, interobserver concordance of telediagnosis was lower than face-to-face diagnosis (K = 0.52). After the second dermoscopy step, the concordance declined further (K = 0.38). CONCLUSIONS: Teledermatology was inferior to face-to-face dermatology. Moreover, the diagnostic concordance of telediagnosis decreased after the teledermoscopic step. This finding may be justified by the dermoscopic difficulty of the selected lesions, including Spitzoid proliferations and atypical melanocytic nevi of the elderly. These lesions may represent a potential diagnostic pitfall given their confounding dermoscopic aspects.

RESUMEN

BACKGROUND: Multiple primary melanoma (MPM), in concert with a positive family history, is a predictor of cyclin-dependent kinase (CDK) inhibitor 2A (CDKN2A) germline mutations. A rule regarding the presence of either 2 or 3 or more cancer events (melanoma and pancreatic cancer) in low or high melanoma incidence populations, respectively, has been established to select patients for genetic referral. OBJECTIVE: We sought to determine the CDKN2A/CDK4/microphthalmia-associated transcription factor mutation rate among Italian patients with MPM to appropriately direct genetic counseling regardless of family history. METHODS: In all, 587 patients with MPM and an equal number with single primary melanomas and control subjects were consecutively enrolled at the participating centers and tested for CDKN2A, CDK4, and microphthalmia-associated transcription factor. RESULTS: CDKN2A germline mutations were found in 19% of patients with MPM versus 4.4% of patients with single primary melanoma. In familial MPM cases the mutation rate varied from 36.6% to 58.8%, whereas in sporadic MPM cases it varied from 8.2% to 17.6% in patients with 2 and 3 or more melanomas, respectively. The microphthalmia-associated transcription factor E318K mutation accounted for 3% of MPM cases altogether. LIMITATIONS: The study was hospital based, not population based. Rare novel susceptibility genes were not tested. CONCLUSION: Italian patients who developed 2 melanomas, even in situ, should be referred for genetic counseling even in the absence of family history.

RESUMEN

To assess the patient's capability of performing a correct skin-check examination we investigated the association of melanoma detection pattern with Breslow thickness, by melanoma body area. In this prospective observational study, patients with primary cutaneous melanoma who presented at the Department of Dermatology at the University of Florence between January 2000 and November 2011 were interviewed as part of their clinical data recording procedure at the time of their final histopathological diagnoses of melanoma. With the aim of evaluating a self skin-check, we included patients with melanoma in the anterior part of the trunk (abdomen and chest area), which is generally considered visible in the mirror, and the posterior part of the trunk, which is a more complex area to be self-checked. The treating physician specifically questioned all patients about who had first detected or suspected the lesion that resulted in the histological diagnosis of melanoma in order to compare those who had self-detected (SD) their melanoma with those who had discovered their melanoma during a regular skin-check (RSC) with a dermatologist. A total of 186 melanoma patients were analyzed, with 67% (n=125) of melanomas located on the back and 33% (n=61) in the chest and abdominal area; the majority (55%, n=103) were in the SD group. The median Breslow thickness of the SD group was significantly greater than that of the RSC group: 0.60 versus 0.50 mm (P<0.0001). In the posterior trunk, the frequency of thick melanomas (Breslow≥1.00 mm) was significantly greater in the SD group than in the RSC group (34 vs. 11%; P=0.003), whereas there was no difference in the frequency of thick melanoma by detection patterns in the anterior trunk. Given the influence of the body area in detecting threatening melanoma, we should encourage people to obtain dermatological skin-checks more often. Skin self-examinations cannot be sufficiently accurate.

RESUMEN

So-called lock therapy, consisting of high concentrations of antimicrobials instilled into the lumen of the catheter, has been suggested avoid central venous catheter removal during fungal infection. We report a baby who developed catheter-related candidemia. Systemic antifungal treatment did not resolve the candidemia. Lock therapy with 0.3 mL of ethanol 70% and micafungin sodium 5 mg/L was added to the therapy, and blood cultures became sterile.
