ABSTRACT
Despite the availability of effective treatment regimens for cutaneous tuberculosis, challenges to disease control result from delayed diagnosis, infection with multidrug-resistant mycobacterial strains, and coinfection with HIV. Delayed diagnosis can be mitigated when dermatologists are sensitized to the clinical signs and symptoms of infection and by the incorporation of appropriate diagnostic tests. All cases of cutaneous tuberculosis should be confirmed with histopathology and culture with or without molecular testing. In each case, a thorough evaluation for systemic involvement is necessary. Mycobacteria may not be isolated from cutaneous tuberculosis lesions and therefore, a trial of antituberculosis treatment may be required to confirm the diagnosis. The second article in this 2-part continuing medical education series describes the sequelae, histopathology, and treatment of tuberculosis.

Bleomycin is a useful treatment option for recalcitrant verrucae. Several different methods of bleomycin delivery have been described, including intralesional injection, intralesional injection combined with laser, microneedling, multiple puncture and adhesive tape. We reviewed the literature to evaluate the various methods of bleomycin administration to treat warts, including the different doses, instruments and procedures used. Intralesional injection (cure rate ranged from 67.8% to 99.23%) and topical bleomycin with multipuncture or microneedling methods (63.6% to 100%) were found to be effective in the treatment of warts. Overall, pain is significantly less with microneedling and multipuncture techniques compared with intralesional injection. Bleomycin injection combined with pulsed dye laser, electroporation, or by other methods, such as, microneedle patches or adhesive tape do not seem to be more beneficial than bleomycin administered by intralesional injection, multipuncture or microneedling techniques.

A novel coronavirus (severe acute respiratory syndrome corononavirus-2; SARS-CoV-2) has affected millions of people across the world. The coronavirus disease (COVID-19) resulting from SARS-CoV-2 manifests in variable clinical severity, featuring both respiratory and extra-respiratory symptoms. Dermatological manifestations of COVID-19 are sparsely reported. To study the various dermatological findings in SARS-CoV-2 positive patients in Indian population. Institutional ethical committee permission was sought and102 SARS-CoV-2 positive patients were included in the study. A thorough clinical examination was done to determine the nature and frequency of various dermatological manifestations in these patients. Out of the 102 positive cases, 95 were males. The mean age of the group was 39.30 years. Thirteen patients (12.7%) were found to have dermatological manifestations. Three (2.9%) had maculopapular rash, two (1.9%) had urticarial lesions and eight (7.8%) patients had itching without any specific cutaneous signs. Trunk was the most frequently affected area, followed by the extremities. No mucosal signs and symptoms were detected. Dermatological manifestations were seen in a small group of COVID-19 patients. The presentation may vary in different population groups and based on severity of disease.

The world entered the year 2020 with reports of the emergence of a new viral illness in Wuhan city, Hubei province, China. In January 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified to be the causative novel coronavirus for the cluster of patients suffering from pneumonia in China. The disease was later named as coronavirus disease (COVID-19) and was declared a pandemic by the World Health Organization on March 11, 2020. Several studies, since then, have tried to study and explain the origin of SARS-CoV-2, its structure and pathogenicity, epidemiology, modes of transmission, spectrum of illness and causes of mortality and morbidity. The current management strategies focus on supportive care and prevention of complications. With no definite treatment, as of now, encouraging reports of some anti-viral and anti-malarial drugs in the management of COVID-19 generate some hope. This review intends to cover the current known aspects of COVID-19 and SARS-CoV-19, based on the available literature.

Precise marking of the biopsy site is essential for histoapthological evaluation. Naked eye examination, sometimes, does not help in identifying an appropriate lesion for biospy. Dermoscopy enhance surface and subsurface features in a lesion and can thus be helpful in selecting the most appropriate lesion for biopsy. This manuscript describes the use of a muselet to mark a biopsy site under the vision of a dermatoscope.

Hangnails are short torn down part of skin surrounding the nails. At times they are very painful. The usual treatment advised is cutting the excess skin with clippers or scissors. To provide an instant relief to the patients, we describe a simpler and effective way to use a surgical glue to paste them back in their original position.

Precalcaneal congenital fibrolipomatous hamartoma (PCFH) is a benign under-reported condition of infancy characterized by the presence of soft nodules on precalcaneal plantar surface of the heel. These lesions are usually bilateral solitary and asymptomatic. We present a 2-month-old infant with solitary skin-colored nodules present on precalcaneal plantar aspect of bilateral heels.

Two patients, one with nail lichen striatus and second with idiopathic trachyonychia were treated with intramatriceal injections of platelet-rich plasma. A total of 0.1 ml of the plasma solution was injected into the matrix of the involved nails at three weekly intervals. Follow-up was done at each sitting and thereafter at 16 and 20 weeks. Assessment was done both photographically and by dermoscopy. Case 1 showed marked improvement within 3 weeks and Case 2 showed improvement within 6 weeks. No relapses were seen at 16 and 20 weeks of follow up. Intramatricial PRP is a safe and effective therapeutic modality in nail lichen striatus and idiopathic trachyonychia refractory to other treatment options. Further studies with larger sample size and controls are required to validate the results.

Dermatoscopy is a noninvasive, painless, and easily repeatable technique that reveals interesting and characteristic features associated with various cutaneous conditions. Lichen nitidus is a rare dermatosis of childhood. We describe the dermatoscopic features in 8 cases of lichen nitidus, which can aid noninvasive diagnosis. The report serves to emphasize the need for examining these lesions using both polarized and nonpolarized modes.
