Nonmelanoma skin cancers (NMSC) are the most common malignancies in solid organ transplant recipients. The most common types of skin cancer in these patients are squamous cell carcinoma (SCC), ...followed by basal cell carcinoma. In immunosuppressed patients, specifically patients after solid organ transplantation, these carcinomas tend to be more aggressive and have a much higher incidence of metastasizing compared to general population. We present a case of a patient who developed numerous SCCs after successful heart transplantation. SCCs which occurred in our patient were mostly treated surgically. However, the lesion on the scalp relapsed after it had been treated surgically three times and therefore superficial x-ray radiation therapy was administered due to its localization and extensive size. In the next year, five more new SCCs occurred throughout the patient's body and all of them were removed surgically. Soon afterwards, the patient died from adenocarcinoma of the colon which rapidly progressed and metastasized.
Abstract Nonmelanoma skin cancer (NMSC) is the most common cancer, with the median age at NMSC diagnosis is 71 years. Treatment options for NMSC include surgical therapy, which is usually the ...first-choice treatment, and nonsurgical modalities. Therapeutic modalities depend on tumor localization, histologic type, and biologic behavior, as well as patient comorbidities, age, and life expectancy. Nonsurgical treatments include cryotherapy, local therapies (imiquimod, 5-fluorouracil, ingenol mebutate, and diclofenac), photodynamic therapy, radiotherapy, and hedgehog inhibitors. Some of these treatments can be combined with curettage and electrodesiccation for better outcomes. Every treatment modality has advantages and disadvantages that must be carefully considered individually. Because the facial area is the most common localization of NMSC, treatment modalities with better cosmetic outcome are preferred. Although NMSC mostly occurs in the elderly, this review is focused on the features and nonsurgical therapy of NMSC in deep old age (≥85) and long-lived persons (aged >95); however, clinical trials very rarely involve this population group due to poor cooperation or poor general condition of these patients; thus, the respective knowledge being generally based on clinical experience.
Psoriasis is a common chronic inflammatory skin disease which affects 0.5–1 % of children and 2–3 % of the adult population. In Croatia, 1.6 % of the population suffer from psoriasis. Distribution of ...the disease is bimodal, with the first peak at the age of 20–30, and the second at the age of 50–60. The etiopathogenesis of the disease is multifactorial, the key factors being genetic predisposition combined with immunological disorders, environmental factors and skin barrier damage. There are several clinical variants of the disease. The main signalling pathways in psoriasis include TNF-α, IL-23 and IL-17. Topical agents are used for the treatment of the mild form, and the systemic conventional therapy is used for the treatment of moderate to severe forms of the disease. In cases where’s no response, or intolerance or contraindications are present, new targeted medications are to be administered. Development in the field of immunogenetics of psoriasis leads to personalized medicine.

Abstract During the aging process, the appearance of the human face changes significantly due to fundamental alterations in the bones, soft tissues, and skin. Both endogenous and environmental ...factors are involved in age-related transformations of the face; however, facial skin is particularly influenced by environmental factors, and the risk of overexposure and consequent premature facial aging. This review summarizes the current state of knowledge of the most common facial skin changes in the mature patient, including pathogenesis of both intrinsic and extrinsic skin aging, as well as clinical and histologic features of skin aging. Because the majority of facial skin changes in the elderly develop as the consequence of ultraviolet radiation, these can be prevented by adequate photoprotection.
Abnormal scarring and its accompanying esthetic, functional, and psychological sequelae still pose significant challe nges. To date, there is no satisfactory prevention or treatment option for ...hypertrophic scars (HSs), which is mostly due to not completely comprehending the mechanisms underlying their formation. That is why the apprehension of regular and controlled physiological processes of scar formation is of utmost importance when facing hypertrophic scarring, its pathophysiology, prevention, and therapeutic approach. When treating HSs and choosing the best treatment and prevention modality, physicians can choose from a plethora of therapeutic options and many commercially available products, among which currently there is no efficient option that can successfully overcome impaired skin healing. This article reviews current therapeutic approach and emerging therapeutic strategies for the management of HSs, which should be individualized, based on an evaluation of the scar itself, patients' expectations, and practical, evidence-based guidelines. Clinicians are encouraged to combine various prevention and treatment modalities where combination therapy that includes steroid injections, 5-fluorouracil, and pulsed-dye laser seems to be the most effective. On the other hand, the current therapeutic options are usually empirical and their results are unreliable and unpredictable. Therefore, there is an unmet need for an effective, targeted therapy and prevention, which would be based on an action or a modulation of a particular factor with clarified mechanism of action that has a beneficial effect on wound healing. As the extracellular matrix has a crucial role in cellular and extracellular events that lead to pathological scarring, targeting its components mostly by regulating bone morphogenetic proteins may throw up new therapeutic approach for reduction or prevention of HSs with functionally and cosmetically acceptable outcome.
Psoriasis is a chronic inflammatory disease that can often accompany human immunodeficiency virus (HIV) epidemics. Development of psoriasis in HIV patients is correlated with a decrease in CD4+ ...count. Significant variability in the clinical presentation of psoriasis makes it a challenging disease to diagnose. Furthermore, associated immunodeficiency complicates standard treatment with immunosuppressive and biological therapy. Articles that match the terms psoriasis and HIV were searched in MEDLINE and Embase and selected based on their relevance. Highly active antiretroviral therapy (HAART) is a medication regimen used to manage and treat HIV infection. In treating mild psoriasis in HIV-positive patients, topical agents combined with HAART are considered first-line therapy, followed by phototherapy. Second-line therapy includes oral retinoids, alone or combined. In treating challenging cases, apremilast has been used due to its lack of immunosuppressive effect. In case of progressive and refractory disease, limited data from studies suggest that immunosuppressive or biological therapy may be effective. Treatment of psoriasis in HIV patients remains a challenge, which is largely attributable to its complicated etiopathology and lack of an approved therapy option. In treating severe psoriasis, close collaboration with an infectious disease specialist is highly recommended. Further research is needed, preferably with an aim toward developing individualized therapy.
During recent decades, the number of patients diagnosed with cancer has been increasing. Conventional treatments, which comprise chemotherapy, radiotherapy, surgery, and hormonal treatment, represent ...improvements in effectiveness and safety of administration and continue to be the standard model of treating malignancies. Advances in oncology have enabled the development of newer therapies such as immunotherapy and targeted therapy. However, numerous adverse events continue to emerge, including dermatologic adverse events, which significantly impact the course of treatment, treatment outcomes, and patient quality of life. Alopecia occurs most commonly, along with mucositis, xerosis, pruritus, hyperpigmentation, acral erythema, nail changes, and many others. The early detection, monitoring, and adequate treatment of these adverse events could prevent reduction, interruption, or permanent discontinuation of oncologic therapies. Herein we review various dermatologic adverse events that may occur due to the therapy applied, present their possible treatments, and emphasize the need to evaluate their impact on patient quality of life.
Abstract Chancroid, lymphogranuloma venereum, and granuloma inguinale may be considered as tropical venereal diseases. These diseases were a major diagnostic and therapeutic challenge in past ...centuries. Currently, patients with these bacterial infections that are endemic to the tropics occasionally consult with dermatologists in temperate climates. Due to the increasing frequency of travel to the tropics for tourism and work, as well as the increasing number of immigrants from these areas, it is important for dermatologists practicing in temperate climates to be familiar with the dermatologic manifestations of such infections, to be prepared to diagnose these diseases, and to treat these patients. All three “tropical” infections respond well to prompt and appropriate antimicrobial treatment, although herpes progenitalis still cannot be cured, and the number of people infected keeps growing; moreover, genital herpes can be transmitted by viral shedding before and after the visual signs or symptoms. Acyclovir, valacyclovir, and famciclovir can shorten outbreaks and make them less severe or even stop them from happening. There is currently no etiologic treatment for molluscum contagiosum, and the majority of treatment options are mechanical, causing a certain degree of discomfort. The molluscum contagiosum virus, unlike the other infectious agents mentioned, does not invade the skin.
