Mycosis fungoides (MF) and Sézary syndrome (SS) are the most prevalent non-Hodgkin lymphomas that comprise cutaneous T-cell lymphomas (CTCL), accounting for more than 70% of cases. Following the Tumor Lymph nodes Metastasis Blood system, disease staging is carried out, and within ten years, about thirty percent of patients in the early stages will have advanced disease. Plaques, folliculotropism, and age over 60 are risk factors for progression. A 5-year survival rate of less than 20% is associated with LCT in MF. Treatment requires an interdisciplinary approach; skindirected therapies are available for early stages of the disease, but there are no curative options for advanced stages of the disease other than allogeneic stem cell transplantation. Because of their severe symptoms and poor treatment efficacy, patients in advanced stages have a lower quality of life and a lower chance of survival. In patients with CD30-expressing CTCL, Brentuximab Vedotin has demonstrated better response rates and progression-free survival (PFS); in advanced SS, mogamulizumab has significantly increased PFS. These findings emphasize the need to standardize prognostic factors and improve CTCL treatment.

Primary cutaneous lymphomas are a heterogeneous group of neoplastic diseases in which dermatological examination plays the pivotal role toward a management which must be multidisciplinary by definition [...].

Clear cell acanthoma (CCA) is an uncommon benign epidermal tumor of unknown origin and etiology. It is often solitary, and the presence of multiple CCAs in the same individual is rare. Typically, it presents as a slowly growing plaque or nodule located on the legs with a peripheral scaling collarette. Diagnosis is primarily based on clinical and histopathological findings, with dermoscopy enhancing diagnostic accuracy. The differential diagnosis includes various skin tumors and inflammatory dermatoses. The preferred treatment is surgical excision, as these lesions do not regress spontaneously. We describe a case of a large CCA on the right thigh associated with multiple small nodular lesions scattered across the legs.

Acute or chronic infections have been described among causes of chronic urticaria (CU). Anisakidosis is a human disease caused by the ingestion of larval nematodes of the family Anisakidae. The infestation is acquired by eating raw seafood or undercooked fish and squid. There are considerable variations in the frequency of underlying causes in the different studies and in different countries, such as differences in diets and the prevalence of infections. Anisakis simplex has been recognized as a trigger of both acute and chronic urticarial manifestations. However, there is still lack of evidence about its management and treatment in dermatology. We, therefore, reviewed some biologic properties of Anisakis simplex in order to understand the relationship between its biology and the mechanism it uses to establish chronic dermatological conditions such as urticaria and cause late complications. In addition, we herein report some concerns about the effectiveness of systemic treatment in preventing complications and management in the dermatological settings.

Pruritus is a common dermatological condition; only few studies have investigated pruritus in old patients. To investigate the prevalence and features of pruritus in old patients which refer to the Dermatology Unit, Galliera Hospital in Genoa. We evaluated the demographic characteristics of all the patients attending for any skin condition the Outpatient Clinic at the Dermatology Unit, selecting those with pruritus and particularly focusing on patients aged more than 65 years.Pruritus was present in 36/262 patients (14%; M:F=20:16; mean age:59.55 years). Patients with pruritus older than 65 years were 20/262 (8%; M:F=14:6; mean age:74.6 years), that represented 14% out of the 140 patients aged ≥65 years. We found no statistically differences among patients aged≥65 years (20/36) and patients aged65. In none of these patients an anamnestic association between drug intake and the onset of pruritus was recorded. We confirm that pruritus is a common skin problem, that is equally frequent both sex, in young and old patients, that in almost all cases is related to an underlying skin condition (mainly psoriasis) and that is rarely anamnestic related to a new drug intake.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic neoplasm (less than 1% of primary cutaneous lymphomas and acute leukemia) with a highly aggressive clinical course and frequent skin, bone marrow and central nervous system (CNS) involvement. Despite a frequent initial response to chemotherapy, relapses with eventual leukemic dissemination are extremely common, leading to poor outcomes and a median overall survival (OS) ranging from 8 to 14 months in first line setting, with standard combination chemotherapy regimens. The skin is the first affected site (in almost 90% of patients) where BPDCN may remain confined for weeks or even months (sanctuary?) until a rapid second step with multiorgan involvement occurs. Therefore, it is of uppermost importance to suspect and recognize early skin lesions and to perform and report a skin biopsy as soon as possible. A multidisciplinary approach with coordination among dermatologists, pathologists and hematologists is definitively crucial in diagnosis and management of BPDCN.

Granuloma faciale (GF) is a rare benign chronic inflammatory dermatosis often difficult to distinguish clinically from other diseases, both inflammatory and neoplastic. Dermoscopy can be a helpful diagnostic tool and indeed several dermoscopic criteria observed in GF have been described in literature. We present two patients affected by GF in which we have observed rosettes.

In September 2021 on the platform of the Italian Association of Hospital Dermatologists (ADOI; https://www.adoi.it/) a monthly on-line live session of teledermatopathology was started involving collegial discussion among experienced Italian pathologists about challenging melanocytic tumors using the virtual microscope [...].

This case was presented at the on-line telepathology meeting on the ADOI platform held on October 19th 2022 by Dr Luongo.

We present a patient affected by Monkeypox, showing the typical clinical signs and symptoms of this emergent viral disease. We report a new observation: dermoscopic features of Monkeypox infection.

We report a 47 years old women affected by lymphomatoid papulosis and concomitant mucinous adenocarcinoma of the sigma. Our experience underlines the relevance of performing accurate staging investigations in all lymphomatoid papulosis patients at the time of diagnosis, even in those that are asymptomatic, like our patient, not only for correct classification but also for cancer screening. Clinicians must be aware of the increased risk of lymphomatoid papulosis patients to develop haematological malignancies and non-haematological malignancies compared to general population at the time of diagnosis and at follow-up and therefore lymphomatoid papulosis patients must regularly follow cancer screening programs.

Psoriasis is a complex disease often needing a multidisciplinary approach. In particular, the collaboration between dermatologist and rheumatologist is crucial for the management of patients suffering from both psoriasis (PSO) and psoriatic arthritis (PsA). Here we report a series of recommendations from a group of experts, as a result of a Consensus Conference, defining the circumstances in which it is preferable or even mandatory, depending on the available settings, to rely on the opinion of the two specialists, jointly or in a deferred manner. Indications are given on how to organize a 3rd level joint Dermatology- Rheumatology care unit, in connection with 1st and 2nd level clinicians of both specialties, GPs, and other specialists involved in the management of psoriasis. A potential patient journey is suggested, that can be used as a basis for future design and validation of national and/or local diagnostic therapeutic and assistance pathways.

Few studies have examined pruritus in elderly patients, a common dermatological condition. The study examines pruritus prevalence and characteristics in elderly patients referred to the Dermatology Unit, at Genoa's Galliera Hospital. The demographic characteristics of all Outpatient Clinic patients with any skin condition were examined, focusing on pruritus patients over 65. Pruritus was present in 36/262 patients (14%; M:F =20:16; mean age: 59.55 years). About 14% of 140 patients aged ≥65 years had pruritus, with 20/262 (8%; M:F =14:6; mean age: 74.6 years) exhibiting it. Visual analog score pruritus did not differ between patients aged ≥65 years (20/36) and <65 years (16/36) statistically. In 89% of patients, itch was related to a dermatological condition, mainly psoriasis. Only extracutaneous diseases resulted more frequently in the patients aged >65. No anamnestic link was found between drug use and pruritus in these patients. We confirm that pruritus is a common skin problem that affects both sexes, young and old, and is almost always caused by an underlying skin condition (mainly psoriasis). It is rarely caused by a new drug. [ABSTRACT FROM AUTHOR]

In 2019, as well as being my last year of service in the hospital, I thought that it would also be the last as the organizer of melanocyte meetings. So, I thought of organizing these meeting as traveling sessions. In February and in March we were hosted in Modena by Anna Maria Cesinaro, in April and May in Reggio Emilia by Simonetta Piana, then in Trento by Mattia Barbareschi [...].

Syphilis is one of the greatest masqueraders in dermatology, like mycosis fungoides or sarcoidosis. In fact, secondary syphilis can simulate different dermatological conditions, not only clinically but also histopathologically. A 34-year old Brazilian man from Manaus (Amazonas) attended our Department complaining for 2 weeks of asthenia, weight loss and multiple asymptomatic disseminated erythematous papules and scaly plaques with well-defined borders and a tendency to confluence were observed on the trunk, neck and extremities, clinically similar to psoriasis guttata. The skin biopsy and laboratory tests disclosed secondary syphilis and the patient was treated with intramuscular benzathine penicillin with prednisolone, with a complete resolution. Psoriasiform syphilis, which imitates psoriasis, was well known by old dermatologists and was called syphilide psoriasiforme or psoriasis syphilitique. Psoriasiform syphilis is one of the atypical presentations of secondary syphilis and dermatologists should be aware of psoriasiform syphilis in order not to improperly treat syphilis patients with immunosuppressive drugs; also, pathologists should be aware of secondary syphilis histopathological features.

The term non-melanoma skin cancer (NMSC) refers to skin cancer different from melanoma, and it is usually restricted to basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and their pre-cancerous lesions, e.g., actinic keratosis. These conditions represent the most frequent tumors in Caucasians and are characterized by an increasing incidence worldwide and a high socio-economic impact. The term Integrated Care Pathway (ICP) refers to “a complex intervention for the mutual decision making and organization of care processes for a well-defined group of patients during a well-defined period”. The purpose of this paper is to present a proposal from the Italian Association of Hospital Dermatologists (ADOI) for an ICP organization of care of NMSC, considering the hub-and-spoke model in the different geographical areas. This proposal is based on the most recent literature and on documents from the Italian Association of Medical Oncology (AIOM), the European consensus-based interdisciplinary guidelines from the European Association of Dermato- Oncology (EADO), and the National Comprehensive Cancer Network (NCCN). We initially discuss the NMSC outpatient clinic, the role of the multidisciplinary working groups, and the hub-and-spoke model regarding this topic. Then, we define the ICP processes specific for BCC and SCC. The ICP for NMSC is an innovative strategy to guarantee the highest possible quality of health care while the hub-andspoke model is crucial for the organization of different health care structures. Considering the importance on this topic, it is essential to create a valid ICP together with an efficient organization within the different geographical areas.

Patient under anti-TNF-alpha treatment have an increased risk of mycobacterial infections, particularly tuberculosis. Only four case reports of Mycobacterium kansasii infection under anti-TNF-α treatment (two with etanercept, two with infliximab) have been reported, but none under adalimumab. A 72-year-old man treated with adalimumab for psoriasis vulgaris and arthropathic psoriasis, complained on nocturnal cough, occasional hemoptysis and the new onset of ill-defined, reddish, asymptomatic persistent plaquesnodules covered by serum crusts on his back, on the dorsum of the right hand and right middle finger. Routine laboratory investigations, HIV and TB screening (QuantiFERONTB- Gold test) were all within normal limits. A skin biopsy was inconclusive and special stainings resulted negative for microorganisms. Only PCR identified M. kansasii. The patient stopped adalimumab and started anti-TB treatment with gradual improvement of the skin lesions. At 26 months follow-up visit no signs or symptoms of relapse of M. kansasii disease occurred.

Prof. Raffaele Gianotti (“Raf” for friends) was born on July 7th,1959 in Milan (Italy). His father, Prof. Ferdinando Gianotti (1920-1984), was a famous pediatric dermatologist that gave his name to the “papular acrodermatitis of childhood” (Gianotti-Crosti Syndrome) [...].

Dermatology Reports is an open access journal published online since 2009. It is devoted to any aspects of dermatology and it is indexed in most citation databases, such as Medline and Embase. Recently, the journal changed, in a sense, its life by becoming the Official Journal of the Italian Association of Hospital Dermatologists (ADOI - Associazione Dermatologi-Venereologi Ospedalieri Italiani e della sanità pubblica) and, thanks to an agreement with ADOI, of the Italian Melanoma Intergroup (IMI).

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic neoplasm (less than 1% of primary cutaneous lymphomas and acute leukemia) with a highly aggressive clinical course and frequent skin, bone marrow and central nervous system involvement. Even though there is often an early response to chemotherapy, leukemic dissemination relapses are very common and result in poor outcomes, with a median overall survival of 8 to 14 months in the first-line setting using standard combination chemotherapy regimens. Almost 90% of patients experience skin involvement as their initial site of infection, where BPDCN may stay restricted for weeks or even months until a swift secondary phase involving multiple organs takes place. Consequently, it is crucial to suspect and identify early skin lesions, as well as to conduct and report a skin biopsy as soon as possible. In order to diagnose and treat BPDCN, a multidisciplinary strategy involving collaboration between pathologists, hematologists, and dermatologists is unquestionably essential. [ABSTRACT FROM AUTHOR]
