Dermatoscopy: Physics and principles
Balakrishnan Nirmal
July-December 2017, 4(2):27-30
Dermatoscopy is an in vivo noninvasive technique used to examine pigmented and amelanotic skin lesions. The technique is performed using a hand-held self-illuminating device called dermatoscope that visualizes features present under the skin surface that are not normally visible to unaided eye. The images from the dermatoscope can be digitally photographed or recorded for future reference. Nonpolarized dermatoscopy requires contact with the skin surface and interface fluid between glass and skin surface. Polarized light penetrates deeper than the nonpolarized light and does not require contact fluids.

Dermoscopy of non-melanocytic and pink tumors in brown skin: A descriptive study
Balachandra S Ankad, Punit S Sakhare, Mural H Prabhu
July-December 2017, 4(2):41-51
Introduction: Skin tumors are classified as melanocytic and non-melanocytic based on presence of melanocytes and melanin pigment in the tumor. Dermoscopy, being a non-invasive technique, is a proven method in recognizing the non-melanocytic and pink tumors by showing specific patterns. In Indian subcontinent, reports on dermoscopy of non-melanocytic and pink tumors are confined only to case reports. Authors studied dermoscopic features of non-melanocytic and pink skin tumors in dermoscopy. Materials and Methods: Study was carried in a tertiary hospital attached to S.Nijalingappa Medical College, Bagalkot, between January and December 2016. It was a descriptive study. Patients with signs of non-melanocytic and pink tumors were selected. Demographic data, such as age, gender, and clinical variables in terms of site of tumor and duration were documented. Manual DermLite 3 and videodermoscopy were employed. Both polarized and non-polarized versions were used for examination. Results: Totally 128 patients were present with 75 females and 61 males. Study included pyogenic granuloma (39), squamous cell carcinoma (4), basal cell carcinoma (30), keratoacanthoma (3), seborrheic keratosis (15), trichoepithelioma (2), syringoma (5), apocrine hydrocystoma (2), fibrokeratoma (5), dermatofibroma (6), epidermal cyst (7), sebaceous hyperplasia (2), Bowen's disease (1), steatocystoma multiplex (1), Lymphangioma circumscriptum (3) and milia (3). Numbers in parenthesis indicate number of patients. Conclusion: Dermoscopy of non-melanocytic and pink tumors demonstrates characteristic patterns which vary from white, yellow, brown to blue and red color depending on presence of keratin and hemoglobin. Patterns differ based on the type skin color. Recognition of distinctive vascular and keratin related pattern is of great help in the diagnosis of skin tumors. To the best our knowledge, this is first report of dermoscopy of non-melanocytic and pink tumors on a larger scale from Indian subcontinent.

Diagnostic utility of onychoscopy: Review of literature
Chander Grover, Deepak Jakhar
July-December 2017, 4(2):31-40
Onychoscopy is being increasingly used as a diagnostic modality for various nail diseases. Initial research had focused mainly on nail pigmentation and nailfold capillaroscopy; however, it is now being evaluated in various infectious and inflammatory nail disorders as well. The present review aims to summarize current knowledge about onychoscopic diagnostic criteria in nail diseases. The best level of evidence attached to each indication is mentioned to answer the pertinent question: How much can we rely on onychoscopy in confirming diagnosis of nail disease?

Dermatopathologic emergencies part I
Douglas Hoffman Atmatzidis, Karl Hoegler, Amy R Weiss, W Clark Lambert
July-December 2017, 4(2):21-26
In dermatopathology, there are several conditions which must be addressed emergently. While some conditions necessitate emergent intervention because of the pathology of the cutaneous manifestations, others require recognition of the underlying serious systemic conditions represented by the cutaneous signs and symptoms. We describe the desquamating disorders (Staphylococcal scalded skin syndrome, Stevens–Johnson syndrome/toxic epidermal necrolysis, and edema-related desquamation), erythema multiforme, cutaneous aspergillosis, tinea/Candida overlying fractures, rickettsial infections, and eczema herpeticum as diseases which should be addressed immediately upon presentation because of the seriousness and rapidity of progression of their pathology. Moreover, porphyria cutanea tarda, Birt-Hogg-Dubé syndrome, Muir-Torre syndrome, and acquired ochronosis may exemplify conditions where the cutaneous signs serve as warnings for severe systemic disease that may not be emergencies in isolation, but can indicate rapid occult development of destructive and sometimes deadly noncutaneous pathology. The literature review was conducted using searches in Pubmed and references to textbooks on the subjects.
