ABSTRACT
BACKGROUND: The location of cutaneous melanoma is associated with photoexposure. OBJECTIVES: To retrospectively analyze changes in the location of cutaneous melanoma over the past 30 years. PATIENTS AND METHODS: All patients treated at our hospital for cutaneous melanoma from 1988 through 2017 were prospectively collected. Data obtained in cases diagnosed from 1988 through June 2006 were compared to those diagnosed from July 2006 through 2017. RESULTS: A total of 1,937 patients (876 men and 1061 women; median age, 57 years; interquartile range 27) were diagnosed with primary cutaneous melanoma. The location of melanoma was head and neck (470 cases), trunk (745 cases), upper limbs (239 cases), and lower limbs (483 cases). From July 2006 through 2017 we detected an increase in the incidence of head and neck melanomas (19.9% vs 28.6%, p <0.001). A drop in the incidence of melanomas located in the lower extremities was also seen in women (39.8% vs 30.4%, p <0.001), and in the trunk men (57.5% vs 47.3%, p=0.003). In the multivariate analyses, only the decrease in melanomas located in lower extremities in women remained significant. CONCLUSION: The increased incidence of head and neck melanomas in both sexes and the decrease in trunk melanomas in men can be attributed to the aging of our population. The reduction in the incidence of melanomas in the lower extremities in women could be associated with changes in photoexposure patterns. Analyzing the factors possibly associated with these changes would contribute to better understanding the pathogenesis of cutaneous melanoma for prevention purposes.
ABSTRACT
PURPOSE: The "Impact of scalp pruritus in dermatological consultations in Spain: The SCALP-PR trial" was initiated to address the common yet often insufficiently examined issue of scalp pruritus in dermatology. This condition leads to an uncontrollable urge to scratch, affecting the patients' quality of life and potentially causing scalp damage. This study aimed to explore the prevalence, patient profile, underlying conditions, and therapeutic approaches for scalp pruritus in Spain, and to assess the safety and efficacy profile, as well as the tolerability of a non-pharmacologic treatment. METHODS: From 2021 through 2022, 75 dermatologists enrolled a total of 359 patients in a study on scalp pruritus, approved by the Bellvitge University Hospital Research Ethics Committee, Barcelona, Spain. This evidence-based research combined a meta-analysis with observational study techniques focused on real-world evidence to examine the therapeutic impact on quality of life (QoL). Utilizing the Dermatology Life Quality Index (DLQI) for QoL assessments, the study evaluated the effectiveness of the topical product over 15 days. Data collection was conducted via an eCRF and analyzed with statistical methods to provide reliable insights into the management of scalp pruritus. RESULTS: The prevalence of scalp pruritus in Spain was found to be 6.9%, predominantly among women with a mean age of 52.5 years. The leading causes identified were seborrheic dermatitis and pruritus of undetermined etiology or sensitive scalp. Stress was noted as a key factor, with corticosteroids and hygienic measures being common therapies. The topical product demonstrated significant reductions in pruritus and scratching in more than 90% of patients after 15 days. Improvements were also seen in dermatological quality of life, with 87.1% of patients showing enhancements in DLQI scores. The product was well-received thanks to its cosmetic properties, with high ratings in texture, ease of application, and fragrance. CONCLUSION: The topical product studied is a safe, effective, and cosmetically appealing treatment, improving scalp pruritus in various etiologies for most patients. The results highlight the need for patient-center treatments in dermatology, providing important insights for clinical practice and future research.

ABSTRACT
Los inhibidores de puntos de control inmunitario (ICI) pueden producir toxicidades cutáneas inmunomediadas entre las que se encuentran las reacciones sarcoideas. Nuestro objetivo fue analizar retrospectivamente los datos clínicos e histológicos de los pacientes en tratamiento con ICI que desarrollaron reacciones sarcoideas cutáneas entre 2019 y 2022. Se incluyeron siete pacientes (seis mujeres y un varón, con una edad mediana de 65años). La mediana de tiempo de instauración de la clínica fue de 4meses y la forma de presentación más frecuente fue la sarcoidosis papulosa de las rodillas, seguida de la sarcoidosis subcutánea. En todos se confirmó el diagnóstico histológicamente y no se observaron diferencias respecto a la sarcoidosis idiopática. Solo en dos casos fue preciso retirar la inmunoterapia. Las reacciones sarcoideas por ICI suelen ser leves y no suelen requerir la interrupción del tratamiento. Es fundamental obtener una confirmación histológica para distinguirlas de la progresión tumoral (AU)
Immune checkpoint inhibitors (ICIs) can cause immune-mediated cutaneous adverse events, including sarcoid-like reactions. The aim of this study was to retrospectively analyze clinical and histologic data from patients who developed cutaneous sarcoid-like reactions between 2019 and 2022 while under treatment with ICIs. We studied 7 patients (6 women and 1 man) with a median age of 65years. Median time to onset of symptoms was 4months. The most common presentation was papular sarcoidosis of the knees followed by subcutaneous sarcoidosis. Diagnosis was confirmed histologically in all cases, and no differences were observed relative to idiopathic sarcoidosis. Discontinuation of ICI therapy was required in just two patients. ICI-induced sarcoid-like reactions tend to be mild and generally do not require treatment discontinuation. Histologic confirmation is essential for distinguishing these reactions from tumor progression (AU)

La dactilitis o dedo en salchicha, se define como la inflamación de uno o varios dedos de las manos o de los pies. La dactilitis sarcoidea es una forma poco frecuente de dactilitis, que suele ser debida a la afectación ósea granulomatosa a nivel de las falanges subyacentes. Sin embargo, una apariencia clínica similar puede ser debida a la presencia de una sarcoidosis subcutánea en los dedos. Describimos los casos de 5 pacientes con una dactilitis por una sarcoidosis subcutánea de los dedos. En nuestros pacientes, las lesiones se localizaron en las falanges proximales a diferencia de la dactilitis sarcoidea por afectación ósea, que suele localizarse en las falanges medias y distales. Es importante el diagnóstico diferencial puesto que la dactilitis por afectación ósea suele ser mucho más persistente y asociarse a formas crónicas de sarcoidosis (AU)
Dactylitis, or sausage fingers or toes, refers to the swelling of 1 or more digits. Sarcoid dactylitis is an uncommon form that tends to be caused by granulomatous bone involvement in the underlying phalanges. Sarcoid dactylitis can, however, clinically resemble subcutaneous sarcoidosis with finger or toe involvement. We describe 5 patients with dactylitis due to subcutaneous sarcoidosis of the fingers. In all cases, the proximal phalanges were involved; sarcoid dactylitis, by contrast, tends to affect the medial and distal phalanges. Differential diagnosis is important, as dactylitis due to bone involvement tends to be much more persistent and is generally seen in chronic forms of sarcoidosis (AU)

El linfoma cutáneo primario T CD8+ tipo acral ha sido incluido como entidad provisional dentro de la nueva clasificación revisada de las neoplasias linfoides de la Organización Mundial de la Salud en 20161. Inicialmente fue descrito como proliferación linfoide CD8+ indolente de la oreja2, y se han publicado en la literatura un total de 29 casos de dicha neoplasia. Ninguno de ellos se ha relacionado con reacciones de hipersensibilidad retardada de contacto. Presentamos un caso de linfoma cutáneo primario T CD8+ tipo acral auricular bilobular en clara relación etiológica con el uso prolongado de unos pendientes de oro confirmada con pruebas epicutáneas, estudio histológico, inmunohistoquímico y molecular. Las lesiones cutáneas bilobulares fueron inducidas de nuevo con un test de uso e idénticos resultados a los iniciales y misma clonalidad, lo cual terminó de confirmar tanto el diagnóstico del linfoma como su inducción por el estímulo antigénico del oro (AU)
Primary cutaneous CD8+ T-cell lymphoma has been included as a provisional entity within the new revised classification of lymphoid neoplasms of the World Health Organization in 20161. It was initially described as indolent CD8+ lymphoid proliferation of the ear2 and a total of 29 cases of such neoplasm have been published in the literature so far. None of them have been linked to delayed contact hypersensitivity reactions. We present a case of acral type primary cutaneous lymphoma T CD8+ involving both earlobes clearly related with the prolonged use of gold earrings, confirmed with epicutaneous tests, histopathology, immunohistochemical and molecular studies. Auricular skin lesions were induced again with a provocation test with identical histopathologycal and the same clonality, confirming both the diagnosis of lymphoma and its induction by the antigenic stimulus of gold (AU)

La enfermedad de Paget extramamaria es un carcinoma epidérmico de diferenciación apocrina que se origina en la epidermis o secundario a la diseminación epidermotropa de neoplasias adyacentes o a distancia. Suele presentarse como una lesión eccematiforme, de límites bien definidos, en zonas ricas en glándulas apocrinas como axilas, zona genital y anal. Su pronóstico depende de 2 factores: la profundidad de la invasión del tumor primario y de la presencia o no de tumor asociado. Su sintomatología inespecífica y la lenta evolución de las lesiones a menudo provoca un retraso en el diagnóstico que conlleva un empeoramiento del pronóstico. El diagnóstico de enfermedad de Paget es histológico precisando en ocasiones un estudio inmunohistoquímico. La inmunohistoquímica permite orientar hacia la naturaleza primaria o secundaria de la enfermedad, pero precisará de un estudio de extensión (AU)
Extramammary Paget disease is an epidermal carcinoma with apocrine differentiation originating in the epidermis o secondary to epidermotropic dissemination from a near or distant neoplasm. It usually shows as an eczematiform lesion with well defined margins in areas rich in apocrine glands, such as the axilla, genital and anal areas. Prognosis is defined by two factors: depth of invasion of primary tumour and whether there is an associated tumour. Its non specific clinical signs and slow evolution of the lesions, often delay the diagnosis, which leads to a poor prognosis. The diagnosis of Paget's disease is histological, sometimes requiring an immunohistochemical study. This can orient towards the primary or secondary nature of the disease, but will still need an extension study (AU)
