Summary Dilated pore of Winer is a benign adnexal tumour of follicular differentiation. It has typical clinical feature of asymptomatic, solitary enlarged pore with a keratin plug. Dermoscopy offers further assistance in diagnosis. In this case on dermoscopy, well defined lamellated central blackish area arranged in concentric circles, surrounded by a bluish grey halo was seen with a rim of hyperpigmentation.
Dermoscopy

Background: Dermoscopy, a non-invasive diagnostic tool, has been proven to improve the diagnostic accuracy of vascular tumors since it can aid in identifying vascular structures as well as morphology of vessels. Tumor depth and precise vascular structures can also be evaluated through dermoscopy. Objective: The study aimed to describe the dermoscopic features of red tumors in Filipino patients seen at the Outpatient Dermatology Department of two centers from January 2013 to July 2014. Methods: Patients with red tumors were recruited to the study. Dermoscopic features were described for each tumor, and histopathology was done. Results: A total of 44 patients were included in the study, and 45 red tumors were evaluated. The tumors were located on the face (31%), trunk (36%), and extremities (33%). The majority of the red tumors were confirmed to be vascular tumors (78%) on histopathology. Dermoscopic features that were found in the majority of vascular tumors seen were lacunae and reddish homogenous areas. For non-vascular tumors, vessels were identifiable in 90% of the tumors seen. Conclusion In this study, the use of dermoscopy in the diagnosis of red tumors proved to be a useful preliminary tool that aided in the observation of vascular pattern, albeit red lacunae, red to dark red homogenous areas, and different types of vessels. The identification of these structures may aid in arriving at a more precise diagnosis and help differentiate vascular from non-vascular tumors.
Dermoscopy

Background: Dermoscopy increases the diagnostic accuracy of clinical visual inspection by 5% to 30%. This has led to a reduction of unnecessary excision of benign skin lesions and the earlier diagnosis of malignant skin lesions. Objectives: To compare the concordance agreement of the clinical versus histopathologic diagnosis to the concordance agreement of the dermoscopic versus histopathologic diagnosis of pigmented lesions. Research Design: This is a prospective, cross-sectional study of the clinical, dermoscopic and histopathological features of pigmented skin lesions on patients seen at the Out-Patient Departments of Quirino Memorial Medical Center and Ospital ng Makati from March 2013 to June 2014. Methods: Sixty-eight subjects fulfilled the criteria and were all included in the final analysis. Classification and definitive diagnosis of the lesion as benign or malignant were determined thru clinical, dermoscopic and histopathologic features by one dermatopathologist. Kappa and concordance analyses were performed to determine the statistical and concordance agreement among the results of the three diagnostic procedures, respectively. Results: The statistical agreement between clinical versus histopathologic classification as benign or malignant was good (kappa=0.872), while the statistical agreement was high (kappa=0.872) between dermoscopic versus histopathologic classification. Concordance agreement between clinical versus histopathologic diagnosis showed fair agreement (concordance coefficient=0.2397) as compared to a high agreement (concordance coefficient=0.98) in dermoscopic versus histopathologic diagnosis. Conclusion The use of dermoscopy in pigmented lesions aids the dermatologist in giving an accurate diagnosis without invasive procedures. Knowledge of the dermoscopic features will help in the early clinical detection and management of benign and malignant pigmented skin lesions.

Introduction: Acral lentiginous melanoma (ALM) is the most common type of cutaneous melanoma in Asians that is not associated with ultraviolet radiation (UV) exposure. Dermoscopy enables clinicians to distinguish between benign and malignant acral melanocytic lesions, with some dermoscopic characteristics playing a role in staging and have prognostic implications, which allows for appropriate surgical intervention. The difficulty of making an early diagnosis of ALM is highlighted by this case. ALM’s destructive nature, alongside the patient’s lack of awareness and vigilance, and healthcare access inequality, influences its prognosis. Case Report This is a case of a long-standing acral lentiginous melanoma with no palpable lymphadenopathies in which it was not immediately detected through biopsy. Upon detection, wide excision with 2 cm margins and disarticulation of the 5th digit of the right foot reconstructed with a fasciocutaneous advancement flap with split thickness skin graft, grafted from the right anterior thigh was done.

Objectives: Leprosy is a chronic granulomatous infection caused by the obligate intracellular organism Mycobacterium leprae. Current diagnostic tests for confirmation and treatment monitoring such as slit skin smear and biopsy are invasive and require time for processing, reading, and interpretation. Dermoscopy is a technique that allows the visualization of structures not readily seen by the naked eye. It can be performed at the point of care, providing a non-invasive link between clinical and histopathologic examination. This study aimed to determine the dermoscopic findings and associated clinicopathologic findings of the different forms of leprosy. Methods: A cross-sectional study was conducted. All new and follow-up patients aged 19 years old and above clinically diagnosed with leprosy were invited to participate in the study during the three-month investigation period. Clinical and dermoscopic photographs of representative skin lesions were taken, and a review of slit skin smear and histopathology results was done. Data analysis was performed using Stata SE version 13. The association between dermoscopic findings and the following parameters: anatomic location, Ridley-Jopling classification, WHO classification, treatment duration, and average bacteriologic index were analyzed using Fisher’s exact test. The level of significance was set at 5%. Results: A total of 57 lesions were included. Linear vessels (p=0.031), structureless areas (p=0.008), and globules (p=0.002) were found to be significantly associated with the anatomic location. Decreased hair was found to be significantly associated with treatment duration (p=0.038). No significant associations were found between dermoscopic findings and Ridley-Jopling classification, WHO classification, and ABI. Eight biopsies taken at the time of dermoscopy were reviewed, with all sites showing structureless or globular areas corresponding to the presence of granulomas on histopathology (100%). No other notable associations were observed. Conclusion Dermoscopy is a potentially useful tool to aid in the diagnosis and treatment monitoring of leprosy. Limitations of this study include the small sample size, the preponderance of subjects in the lepromatous pole, and assessments by a single trained dermoscopist. A longer study duration including a larger number of newly diagnosed leprosy patients is recommended.
