RESUMO
OBJECTIVES: Skin changes in acromegaly are often the first sign of the disease. The aim of this study was to describe the cutaneous findings in patients with acromegaly. In addition, a secondary aim was to investigate the possible association of these findings with remission status and concomitant endocrinopathies. DESIGN, PATIENTS, AND MEASUREMENTS: In this prospective multicenter study, 278 patients over the age of 18 years with acromegaly who were followed up in 14 different tertiary healthcare institutions were included. These patients, who were followed up by the Endocrinology Department, were then referred to a dermatologist for dermatological examination. The frequency of skin lesions was investigated by detailed dermatologic examination. Dermatological diagnosis is reached by clinical, dermatological and/or dermoscopic examination, and rarely skin punch biopsy examinations in suspicious cases. The possible association of the skin findings between remitted and nonremitted patients and with concomitant endocrinopathies were evaluated. RESULTS: The most common skin findings in patients with acromegaly in our study were skin tags (52.5%), cherry angiomas (47.4%), seborrhoea (37%), varicose veins (33%), acneiform lesions (28.8%), hyperhidrosis (26.9%) and hypertrichosis (18.3%). Hypertrichosis was significantly more prevalent in patients nonremitted (p: .001), while xerosis cutis was significantly more prevalent in patients remitted (p: .001). The frequency of diabetes mellitus and hypothyroidism was significantly higher in patients with varicose veins and seborrhoeic keratosis than those without. Additionally, the coexistence of hypothyroidism, hyperthyroidism and galactorrhea was significantly higher in patients with Cherry angioma than in those without Cherry angioma (p-values: .024, .034 and .027, respectively). The frequency of hypogonadism in those with xerosis cutis was significantly higher than in those without (p: .035). CONCLUSIONS: Cutaneous androgenization findings such as skin tag, seborrhoea, acne and acanthosis nigricans are common in patients with acromegaly. Clinicians should be aware that skin findings associated with insulin resistance may develop in these patients. It can be said that the remission state in acromegaly has no curative effect on cutaneous findings. Only patients in remission were less likely to have hypertrichosis. This may allow earlier review of the follow-up and treatment of acromegaly patients presenting with complaints of hypertrichosis. Additionally, it can be said that patients with skin findings such as cherry angioma may be predisposed to a second endocrinopathy, especially hypothyroidism. Including dermatology in a multidisciplinary perspective in acromegaly patient management would be beneficial to detect cutaneous findings earlier.

INTRODUCTION: The Flash-lamp pulsed dye laser (FPDL) is nowadays considered the most precise laser currently on the market for treating superficial vascular lesions. In this study, we gathered data from 10 years of experience regarding dye laser treatment of patients presenting vascular malformations such as telangiectasia, rhinophyma, port-wine stain, cherry and spider angioma and vascular tumours. METHODS: Subjects were enrolled from 2013 to 2023 based on the vascular anomalies they presented. They underwent different treatment sessions with the FPDL device. RESULTS: The age-range distribution by vascular anomaly confirmed that haemangiomas are typical in children while rhinophyma is a condition very common in older adults. A difference in sex distribution showed that pathologies such as telangiectasias typically affect women whereas rhinophyma is more frequent in men. Most of the treatments interested the face area but no permanent side effects were registered. CONCLUSIONS: Our 10 years of experience with FPDL demonstrated good results in a wide range of applications for the treatment of different vascular anomalies. The absence of long-term side effects and bearable pain during the treatment makes it a valuable solution for the resolution of benign tumours also in very young patients.

OBJECTIVES: A clinical study to investigate the effectiveness of pulsed dye laser (PDL) versus Nd:YAG laser in the treatment of telangiectasias, spider veins and cherry angiomas. Dynamic optical coherence tomography (D-OCT) was introduced as an innovative follow-up tool for evaluation of blood flow within superficial vessels and to allow visualization of morphological changes of the vasculature in vivo. The final aim of this study was to demonstrate a possible treatment benefit comparing both laser types. MATERIALS AND METHODS: Vessel structures of 102 skin lesions were documented photographically and dermoscopically. Subsequently, lesions were imaged using optical coherence tomography before laser therapy (a), directly after the treatment (p) and after a follow-up 4-6 weeks after laser treatment. All lesions were treated using either a 595 nm PDL or a 1064 nm Nd:YAG laser. Two main vessel parameters, namely density and diameter, and their possible changes during follow-up were observed in 150/300/500 µm penetration depth using D-OCT and were subsequently compared between both treatment groups. Other analyzed vessel parameters were depth of the plexus, mean diameter, mean density, top edge of the vessel, columns, and spikes. RESULTS: Both laser types are suitable options for the treatment of vascular skin lesions, with the most significant effect on cherry angiomas. PDL shows better results treating smaller vessels in upper skin regions, in comparison to Nd:YAG laser, achieving better results on deeper vessels, like spider veins. Using the applied laser settings, there was no statistically significant effect on telangiectasias. CONCLUSION: D-OCT represents a new, noninvasive imaging method to evaluate blood flow and vessel morphology in the follow-up of telangiectasias, spider veins, and cherry angiomas, which underwent laser therapy.

Cherry angiomas are the most common vascular tumors of the skin. They are particularly prevalent in the general population and become more common with age. Although an association with cancer was suggested at the end of the 19th century, when these tumors were first described, it could not be demonstrated. For many decades, therefore, cherry angiomas were considered to have no clinical relevance other than their association with age. A number of studies in recent years, however, have shown a link between cherry angiomas and exposure to various toxic substances and medications, benign and malignant diseases, and immunosuppression, rekindling interest in these lesions and providing clues for a better understanding of their etiology, pathophysiology, and clinical relevance.

We present a case of a diffuse, vascular eruption localized to the left thigh and left abdomen in an otherwise apparently healthy 63-year-old male. The patient reported that the eruption was not bothersome and had been present for as long as he could remember. Due to its benign appearance in nature, the patient declined a biopsy or further follow-up. While reports of diffuse vascular eruptions have been associated with many genetic diseases, this case offers an example of a diffuse vascular eruption in a healthy patient. Further research is needed to understand the potential genetic or environmental factors contributing to the development of such lesions in healthy patients.
RESUMO
BACKGROUND: Existing therapeutic methods for reduction or removal of superficial vascular malformations and tumors have high risks of scarring and other complications that result in aesthetic appearance less favorable than the baseline. Patients are often cautioned against intervention, which can lead to psychosocial problems and low self-esteem. Improved treatment modalities are therefore relevant from both medical and aesthetic perspectives. METHODS: Two volunteer subjects were treated with a medical 20 MHz high intensity focused ultrasound device developed for dermatological conditions. One patient was given three treatments to remove a superficial congenital hemangioma on the left middle cheek. The other patient was given a single treatment to remove seven cherry angiomas on the thighs. Handpieces with nominal focal depths of 0.8 - 1.8 mm below the skin surface were used to administer acoustic energy of 1.1 - 1.2 J/dose. An integrated dermoscope in the handpiece was used to monitor the treatment in real-time. RESULTS: During treatment, blood in the capillary network of the lesions was coagulated immediately, and capillary walls were collapsed due to the thermal and mechanical effects of the high intensity focused ultrasound. During the healing phase, the areas regenerated a normal skin structure with very limited scar or dyspigmentation. At follow-up, a clear aesthetic improvement was observed over the baseline for all treated targets with the exception of two cherry angiomas, where focal depth and/or dose coverage had not been optimal. CONCLUSION: High intensity focused ultrasound is concluded to be a safe and efficient skin treatment for benign superficial vascular malformations and tumors.

BACKGROUND: Cherry angiomas (CAs) are very common asymptomatic vascular skin lesions. There are only a few studies on CAs in the literature and those assessing risk factors of CAs are scarce. The aim of our study was to determine risk factors for the development of CAs. MATERIALS AND METHODS: A case-control study was conducted at a tertiary care center in Riyadh, Saudi Arabia. Patients underwent a full-body examination for CAs. Demographics and other data including medical history and medications were extracted from electronic medical records. RESULTS: A total of three hundred patients were enrolled: one hundred cases with at least five CAs and two hundred controls without CAs. Bivariate analysis identified benign prostatic hyperplasia (odds ratio [OR]: = 2.591), malignancy (OR = 2.567), tamsulosin (OR = 3.171), and clopidogrel (OR = 0.321) as statistically significant associations. After multivariate logistic regression analysis, only tamsulosin (OR = 3.475, P = 0.009) and clopidogrel (OR = 0.281, P = 0.028) were found to be independent risk factors for CAs. Malignancies tended to be more associated with CAs, but this did not reach statistical significance (P = 0.07). CONCLUSION: Tamsulosin is a possible risk factor for the development of CAs. Clopidogrel seems to have a protective role preventing the development of CAs.
RESUMO
Human herpesvirus 8 (HHV8) has been hypothesized to be a potential cofactor for the development of diverse cutaneous vascular proliferative lesions, including eruptive cherry angiomas. Recent reports evidenced the influence of killer cell immunoglobulin-like receptor (KIR) gene diversity in defining the susceptibility to symptomatic herpesvirus infections. In this study, skin samples from vascular lesions and healthy controls were characterized simultaneously for the presence of HHV8 and for the KIR genotype, focusing upon the presence of the KIR2DL2/DS2 and KIR2DL3 genes, which have been associated to herpesvirus susceptibility. The results showed that about 64 % of the vascular lesions resulted positive for the presence of HHV8, whereas no control healthy skin samples harbored HHV8 DNA. HHV8-positive patients had a significantly increased frequency of KIR2DL2/DS2 homozigosity and a concomitant decrease of the homozygous KIR2DL3 genotype, compared to healthy controls or HHV8-negative patients. Notably, the simultaneous presence of KIR2DL2/DS2 homozygosity and HHV8 infection resulted in a significantly increased risk to develop cutaneous lesions (OR 5.7) compared to the individual factors alone, suggesting that specific KIR genotypes might predispose to HHV8 symptomatic infection, allowing the virus to exert its angioproliferative activity at skin level.

Angioma serpiginosum is a cutaneous vascular nevoid disorder that presents as red, nonblanchable and grouped macules distributed in a serpiginous pattern and resembles purpura. It usually begins in childhood and commonly affects the lower limbs and the buttocks. Late onset of the lesions is unusual. We report a 46-year-old female who presented with progressively extending lesions on her breast since preceding four years. She also had a cherry angioma overlying the lesions, an observation hitherto not reported so far.
RESUMO
Exposure to SM leads to short and long term adverse effects on various organs including the skin. Cherry angioma is one of the late skin disorders in SM exposed individuals. The pathogenesis of abnormal angiogenesis in cherry angioma is not well known but the role of inflammatory mediators and certain hormones, including prolactin, in the regulation of angiogenesis in other diseases has been reported. Alterations in serum levels of prolactin and chemokines in SM-exposed victims and the impact on angiogenesis are indications of the role in SM-induced cherry angioma. As part of the SICS, this study seeks to evaluate the possible association of prolactin and chemokines in the emergence of SM-induced cherry angioma. The serum concentrations of prolactin, IL-8/CXCL8, RANTES/CCL5, MCP-1/CCL2, and fractalkine/CX3CL1 were titrated using sandwich ELISA technique. There was a significant difference in the level of prolactin between the exposed subgroups (with cherry angioma n=72; mean: 10.13) and without cherry angioma (n=268; mean: 13.13, p<0.0096). Median of the serum levels of CCL2 in the exposed patients with cherry angioma was significantly higher than exposed patients without cherry angioma (median=203.5 pg/ml and median=187.10 pg/ml respectively, p=0.035). There was no significant difference in the serum levels of IL-8, RANTES and CX3L1 between the exposed subgroups with cherry angioma and without cherry angioma. This finding serves as a basis for further research on the molecular mechanisms and pathways involved in the pathogenesis of cherry angioma and other related disorders.
