Ingenol mebutate therapy in erythroplasia of Queyrat: a new approach.

BACKGROUND: Erythroplasia of Queyrat (EQ) is a rare squamous cell carcinoma in situ, usually occurring on the glans penis, the prepuce, or the urethral meatus. Therapy is mandatory because it can progress to invasive carcinoma in up to 30% of cases. Treatment options include 5-fluorouracil, curettage, cryotherapy, radiotherapy, laser, partial or total penectomy, and microsurgery, as also with imiquimod and photodynamic therapies. METHODS: Between 2015 to 2018 we treated five patients, with histologically confirmed EQ, with ingenol mebutate (IM) 0.015% gel applied for 3 days consecutively. RESULTS: Three patients showed complete response at one year follow up. Two patients showed partial response after two months, so they received a second course of therapy with IM. At one-year follow-up, one of them showed complete response, the other partial response. CONCLUSIONS: Our experience demonstrated that IM may be considered as an effective and safe treatment option in EQ. IM offers various advantages such as easy and fast application, rapid complete remission, better compliance, few side effects and excellent cosmetical results. The authors call for further exploitation in bigger trials.

Therapeutic Options for the Treatment of Actinic Keratosis with Scalp and Face Localization.

Actinic keratosis (AK) is a common skin disease related to ultraviolet chronic exposure, that is now considered a squamous cell carcinoma in situ. Primary skin cancer prevention strategies should be recommended for high risk patients. There is a wide spectrum of treatment options available for AKs, and several variables should be taken into account regarding the best therapeutic choice for each patient. The purpose of this article is to review the current treatment strategies for AKs localized on the face and scalp, with a focus on the practical point of view that could be useful for choosing the best therapeutic option. The two main therapeutic approaches will be distinguished first: lesion-directed and field-directed. Afterwards, the treatment based on clinical type and patient comorbidity will be discussed.

Management of psoriatic patients in biologic treatment associated with infectious comorbidities.

INTRODUCTION: Psoriasis is a chronic inflammatory disease affecting about 2% of population, involving both acquired and innate immunity. Psoriasis affects mainly skin, presenting multiple co-morbidities; among them infective ones. Re-activation of tuberculosis or viral hepatitis (HBV and HCV) still represents a therapeutic challenge in patients receiving treatment with biological drugs, as well as HIV infection. For this reason, a multidisciplinary approach with global treatment resulting from active collaboration of different specialists is highly recommended. AIM: To investigate the most common infective diseases as co-morbidities associated with psoriasis and to provide algorithms for screening, follow-up and therapeutic management in psoriatic patients. MATERIAL AND METHODS: We examined the main infectious comorbidities that can affect moderate to severe psoriatic patients, influencing the therapeutic choice as during the biological treatment both viral and tuberculosis re-activation may occur. We have therefore evaluated the main diseases (TB, Hepatitis B and C, HIV) and the monitoring of patients during treatment with biological agents. RESULTS: Regular monitoring of psoriatic patients is recommended during long-term treatment with biological drugs in order to identify cases of re-activation of the latent infective agent or de novo acquired infection. CONCLUSIONS: Here we report the state of art regarding management of psoriatic patients with these co-morbidities suggesting a specific screening and management for infectious diseases in patients with moderate to severe plaque psoriasis.

IL-17 and its role in inflammatory, autoimmune, and oncological skin diseases: state of art.

Recent data support the theory of the involvement of IL-17 in the pathogenesis of several chronic inflammatory skin diseases (psoriasis, atopic dermatitis, acne, hidradenitis suppurativa) and autoimmune skin diseases (alopecia areata, vitiligo, bullous diseases). Even if the role of IL-17 in inflammatory and autoimmune diseases has been reported extensively, its role in tumor is still controversial. Some reports show that Th17 cells eradicate tumors, while others reveal that they promote the initiation and early growth of tumors. Herein, we review the role of IL-17 in the involvement of some common dermatologic diseases: psoriasis, atopic dermatitis, hidradenitis suppurativa, acne, vitiligo, melanoma, and nonmelanoma skin cancers.

Face and Scalp Basal Cell Carcinoma Treatment: A Review of the Literature.

Basal cell carcinoma (BCC) is the most frequent skin cancer and is characterized by slow growth, even if it can be locally invasive and rarely metastasizes. Many different phenotypic presentations and histopathologic subtypes have been described, and the current guidelines subdivide BCCs into low-risk (nodular and superficial) and high-risk subtypes (micronodular, infiltrating, and morphoeic BCC and those with squamous differentiation). Dermoscopy allows the identification of the features associated with these different subtypes. Compared with the low-risk forms of BCC, more aggressive ones tend to undergo more frequently incomplete surgical excision and perineural invasion, so the identification of these lesions before surgery is extremely important. The gold standard of treatment is surgery, particularly for the H region of the face and infiltrative lesions, but other options are available and selected according to many variables, including body area, age, comorbidities, and clinical, dermoscopic, and histopathological features of the lesion. Moreover, the possible complications of surgical approaches, namely healing defects, failure of skin grafts, and wound infection, should be considered. In this review we discuss the management of BCC localized on the face and scalp, according to the currently available treatment options.
