ABSTRACT

BACKGROUND: Xanthelasma palpebrarum is the most common cutaneous xanthoma characterized by soft, yellow papules or plaques that arise on the periorbital skin. As these lesions can be cosmetically disfiguring, many patients seek medical help to remove these lesions. OBJECTIVE: To determine the effectiveness and minimum number of treatment sessions with a 1064-nm, Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser for the treatment of xanthelasma. METHODS: A retrospective review of patients with xanthelasma consecutively treated with Q-switched Nd:YAG laser was conducted. Forty-six patients with 103 lesions were identified from January 2012 through August 2015. Photographs taken of patients immediately before treatment and 4-8 weeks after treatment were independently evaluated by 2 dermatologists. RESULTS: After a single treatment session, 93.2% of lesions had some degree of clearance. All lesions had excellent-to-complete clearance after at least 4 treatment sessions. Patients usually required 4 treatment sessions for optimal results. LIMITATIONS: This was a retrospective study. Treatment parameters varied, follow-up periods were not uniform, and response was not assessed with a validated scale. CONCLUSION: The Q-switched Nd:YAG laser is effective and well tolerated in the treatment of xanthelasma in our study population.

ABSTRACT

Eccrine tumors are adnexal tumors with a varied clinical presentation and wide histological spectrum. This study aims to consolidate data on the clinical characteristics of eccrine tumors to help improve clinical acumen and management of such tumors. Histopathological records from January 2008 to December 2012 were retrieved. Clinical characteristics of the tumor including site, appearance, symptoms, color, duration prior to presentation, and clinical and histological diagnosis were recorded. Eighty-four patients with eccrine tumors were identified, with seven main types of tumors recognized-hidradenoma (33.3%), poroma (29.8%), mixed tumors (14.3%), spiradenoma (8.3%), porocarcinoma (6.7%), eccrine adenoma (3.6%), and syringoma (3.6%). A total of 50% of mixed tumors were misdiagnosed as epidermal cysts. Eccrine tumors have a wide array of clinical presentations and are often clinically misdiagnosed as cysts. Recognizing certain clinical features may aid in the diagnosis, but, if in doubt, a biopsy should be performed.

ABSTRACT

Poikiloderma-like cutaneous amyloidosis (PCA) is a rare variant of primary cutaneous amyloidosis. It was first described in 1929 and there are two clinical forms of PCA, the ordinary type and PCA syndrome. The characteristics of PCA include poikiloderma-like skin changes, lichenoid papules, blister formation, and cutaneous amyloid deposits on histological examination. These skin lesions usually occur at the extremities, consistent with the few cases that have been reported. We present a case of a 62-year-old man who presented with the features of poikiloderma-like cutaneous amyloidosis. Diagnosis of this unique condition is a challenge and a skin biopsy is necessary in such instances. A discussion of the differential diagnosis of this condition is also included.

ABSTRACT

BACKGROUND: Chronic urticaria is a common skin condition that causes significant impact on patient's quality of life. OBJECTIVE: The purpose of the study was to assess adherence to therapy and quality of life of patients with chronic urticaria. We also aimed to study the relationship of medication adherence and quality of life of patients with chronic urticaria. METHODS: A cross sectional study was conducted with 103 patients from the dermatology clinic of National University Hospital, Singapore. Patients with chronic urticaria were asked to fill out a questionnaire for assessment of adherence to therapy and quality of life. We used the Morisky 8-Item Medication Adherence Scale to categorize adherence as high, medium, low. For assessment of quality of life, we used the validated chronic urticaria quality of life questionnaire (CU-Q2oL) by Bairadani et al. RESULTS: The highest median scores for the items measuring quality of life were interference with sleep and pruritus. We also observed that the majority of patients (71.9%) had low adherence to medical therapy. No difference in adherence was noted in patients on once daily medication or more frequent dosing. There was no significant difference in the quality of life among patients with low and medium adherence to therapy. CONCLUSION: Quality of life of patients with chronic urticaria does not depend on the patients' adherence to medications. Dosing frequency does not affect adherence in our study population. It is also important to recognize the symptoms and issues most affecting quality of life of patients with chronic urticaria, so as to improve overall management.

ABSTRACT

Solar elastosis is a degenerative condition of elastic tissue in the dermis due to prolonged sun exposure. There are a variety of clinical manifestations of solar elastosis. In its most common form, solar elastosis manifests as yellow, thickened, coarsely wrinkled skin. We report two uncommon cases of severe solar elastosis with a papular morphology. Its presentation can closely mimic a host of cutaneous disorders and thus, although it is helpful to be cognizant of this entity, it is still crucial to biopsy these lesions to avoid missing a more sinister condition.
