Dermoscopy in Leprosy: A Clinical and Histopathological Correlation Study.

BACKGROUND: Leprosy, an insidious infectious granulomatous disease, is diagnosed traditionally through clinical examination coupled with skin smears and histopathology. It has myriad clinical presentations that pose diagnostic challenges. Lately, dermoscopy has emerged as a rapid, noninvasive diagnostic modality for many dermatoses. OBJECTIVES: We evaluated the dermoscopic findings of various manifestations of leprosy and correlated them with clinical and histopathological features. METHODS: This prospective, cross-sectional study was conducted in our skin outpatient department for a period of 1 year. Patients newly diagnosed as having leprosy or those undergoing leprosy treatment for less than 6 months were included. The most representative lesion was dermoscopically evaluated and later biopsied. RESULTS: We included 73 patients in the study. Results indicated an obvious correlation between dermoscopic findings and histopathology. We noted orangish yellow and white structureless areas, steadily throughout the spectrum, depicting dermal granuloma. Additionally, we observed focal vascular structures such as branching, linear, and crown vessels that result from the pressure of granuloma pushing the dilated vessels upwards. The relative absence of skin appendages aided in differentiating leprosy from other granulomatous disorders. Novel findings of our study were the detection of a branch-like pattern of clofazimine-induced pigmentation on dermoscopy and orange globules on onychoscopy. Other unique findings included violaceous structureless areas, characteristic large telangiectatic vessels, follicular plugging, star-shaped silvery-white scaling, and white globules in type 1 reaction; white shiny steaks were observed in patients with borderline lepromatous leprosy, and central white dots and keratotic plugs were observed in patients with histoid leprosy. CONCLUSIONS: Dermoscopy, as a noninvasive modality, could aid in the quick diagnosis of leprosy and should be used as a handy tool to complement other investigative tools for this disease.

Endocrinological Testicular Dysfunction in Patients with Lepromatous Leprosy and the Impact of Disease on Patient's Quality of Life.

INTRODUCTION: Leprosy or Hansen's disease poses a drastic impact on the quality of life in affected patients even after successful completion of treatment. The involvement of the endocrine system in leprosy is usually insidious, silent, and under-reported, especially the testicular dysfunction. AIMS AND OBJECTIVES: The present study was aimed at evaluating the abnormalities of the primary testicular hormone testosterone and the gonadotrophins LH and FSH in male patients affected with lepromatous leprosy and assessing the impact of the disease on quality of life (QOL). MATERIALS AND METHODS: The study included 43 married male patients diagnosed with lepromatous leprosy. Careful history taking and examination for symptoms of testicular dysfunction were done. Serum concentrations of total testosterone, FSH, and LH were noted. The QOL was evaluated using the WHO Quality of Life-BREF (WHOQoL-BREF). RESULTS: The most common clinical manifestation of testicular dysfunction was reduced or loss of libido reported in 12 (27.9%) patients followed by gynaecomastia in 7 (16.3%). Ultrasonographic (USG) analysis revealed reduced testicular volume in 31 (72.1%) patients, and average testicular volume was 11.9 ± 4.9 mL each. Seventeen (39.5%) patients had low serum testosterone levels, 9 (20.9%) had high serum FSH level, and 11 (25.6%) high LH levels. There was a significant negative correlation between testosterone level and FSH as well as LH. There was also a significantly positive correlation between testicular volume and testosterone level. Symptomatic patients with gynaecomastia/gynaecothelia had higher hormonal derangement than those who had other symptoms. On QOL, most patients scored lowest on the domain of "social relationships" (including sexual wellbeing) followed by "psychological health". CONCLUSION: We found a high rate of USG diagnosed testicular atrophy in lepromatous leprosy patients. Therefore, every leprosy patient should be thoroughly examined clinically to rule out features of testicular dysfunction. Testicular function tests should be routinely carried out in all leprosy patients to arrive at an early diagnosis. Leprosy is found to affect all domains of a patient's quality of life.

Falknor's needling method as a potential immunotherapy in palmo-plantar warts.

BACKGROUND AND AIM: Treatment of palmoplantar warts is a challenge for dermatologists. We aimed to study the efficacy and safety of Falknor's needling method in palmoplantar warts. METHODS: In an open, nonrandomized study, the index wart of eligible patients was punctured several times with a 26-gauge needle to produce a "beefy" red wound. Patients were followed up to 6 months. RESULTS: Out of 82 patients, complete resolution occurred in 58 (70.7%) and partial response in 5 (6.1%) patients. Nine (10.9%) patients developed secondary infection. LIMITATIONS: Small sample size, No comparison group. CONCLUSION: Falknor's needling method provides a high rate of complete resolution after a single treatment session. It is easy to perform and is cost effective.

Bleomycin induced flagellate pigmentation.

Bleomycin frequently causes cutaneous toxicity in the form of pigmentary disturbances. We report 2 patients with testicular tumours who developed distinctive "flagellate" pigmentation on trunk and extremities during bleomycin therapy.
