Introduction Nail diseases may often possess a challenge for the treating dermatologist, as they may primarily be affected without any skin involvement and sometimes may present with subtle changes which can be easily missed by the naked eye. The macroscopic nail changes can be assessed very well with a naked eye, however, the important minutiae may be assessed with a dermoscope. Aim To study the characteristic dermoscopic findings in various nail diseases. Materials and methods A total of 250 patients (males-130, females-120) with clinically evident nail diseases were enrolled in this cross-sectional descriptive study. After a thorough clinical examination, patients were subjected to dermoscopic examination of all 20 nails. Chi-square test or Fisher's exact test (in a very few patients of nail diseases) were used for statistical analysis, with a significance threshold of p < 0.05. Results Nail psoriasis (n = 45) was the commonest nail disease found in which the most common dermoscopic feature was circular punctate depressions (64.5%). Onychomycosis (n = 40) was the next common disease in which yellowish discoloration (100%) was commonly seen in all patients and rough scaly surface (100%) in the total dystrophic type. In pitted keratolysis (n = 19) transverse brown bands (57.9%) were most commonly seen as was the case in eczemas. Lichen planus (n = 14) was associated with longitudinal fissuring (64.3%) most commonly. Trachyonychia (n = 5) was associated with longitudinal fissuring (100%) in all cases. The most common dermoscopic feature of alopecia areata (n = 4) was circular punctate depressions (75%). Systemic scleroderma (n = 4) typically showed giant capillaries (75%) as the most common feature. Conclusion A meticulous search with the dermoscope, furnishes minuscule details of the nail unit that can be diagnostic of several nail diseases at an early stage before dystrophy sets in. However, further studies are required to validate these findings. Clinical significance Dermoscopy is a noninvasive complementary tool which aids in diagnosis of nail diseases more quickly and can also be used for monitoring the evolution, therapeutic response, and prognosis of these diseases.

PK can involve web spaces, nonglabrous skin, and paronychium, and can cause nail changes. The lesions can be inflammatory with crusting and PIH.

Background: Guttate psoriasis (GP) and pityriasis rosea (PR) are a part of papulosquamous disorders that have very similar clinical features and often require histopathology to confirm the diagnosis. Dermoscopy has emerged as a noninvasive, cost-effective technique that can aid in the diagnosis of inflammatory skin diseases like GP and PR. Objective: To study and compare the dermoscopic features of GP and PR. Methods: Twenty consecutive patients each with GP or PR were enrolled in the study. The diagnoses of GP and PR were made clinically and on histopathology. Dermoscopic images were taken of the representative lesions from each patient using a manual dermoscope attached to a digital camera after applying ultrasound gel. Vascular morphology, vascular arrangement, background color, along with color and distribution of scales were noted in each case. Statistical analysis was done using chi-square test to determine the significance of findings in both groups. Results: The combination of a bright red background with dotted vessels in uniform diffuse distribution with diffuse white scales was highly specific for the diagnosis of GP. Lesions of PR showed a red background with dotted blood vessels in nonspecific distribution. Scales were either white in color or brown pigmented with patchy distribution. Brown pigmentation and brown dots were additional findings in cases of PR. Conclusion: Combinations of dermoscopic patterns can aid in the diagnosis of GP and PR in the majority of the cases.

Pseudolymphoma, refers to a heterogeneous group of benign reactive T-cell or B-cell lymphoproliferative processes of diverse causes that simulate cutaneous lymphomas clinically and/or histologically. Thread lift involves the elevation of sagging tissues for rejuvenating the face, which loses its elasticity and volume as one ages, by stimulating the production of new collagen and elastin. The incidence of complications with thread lift is comparatively low, like small ecchymosis, mild erythema, mild transitory hyperesthesia, and mild postoperative tumefaction. [1] Cutaneous pseudolymphoma secondary to facial thread-lift procedure has not been previously reported as a complication. In this case report, we will be presenting cutaneous pseudolymphoma as one of the complications of thread-lift procedures and will be speculating its pathogenesis.
