ABSTRACT
Background Cold urticaria (ColdU) is classified as a subtype of chronic inducible urticaria characterised by recurring pruritic wheals and/or angioedema upon exposure to cold stimuli. However, very limited data is available on ColdU specifically among Indians. Objectives The aim of this study was to describe the clinico-epidemiological characteristics and treatment response in North Indian patients diagnosed with ColdU. Materials and Methods The clinical records of patients diagnosed with ColdU past 5 years (January 2018 to December 2022) were retrospectively reviewed. Data including patient demographics, clinical manifestations, comorbidities, laboratory findings, and treatment response were collected and analysed. Results Among the 1780 urticaria patients included in our study, only 15 cases of cold-induced urticaria were identified. ColdU was classified as typical in all but three patients. The mean age of affected individuals was 36 ± 18 years (20-65 years) and eight patients (53.3%) were males. Mean disease duration at presentation was 18 ± 27 months (3 months-4 years). Two patients experienced cold-induced angioedema and one patient had hypotensive episodes following cold exposure. Twelve patients demonstrated positive results in the ice cube provocation test. Of 15, only 6 (40%) achieved complete control of symptoms with standard dosing of second generation anti-histamines while six patients (40%) required titration to higher doses and three patients (20%) were initiated on cyclosporine therapy, resulting in remission. Limitations Retrospective study design and possibility of selection bias. Conclusion Due to India's predominantly tropical climate, ColdU prevails at lower levels compared to the western regions. ColdU is likely underdiagnosed in India, possibly dismissed as chronic spontaneous urticaria. The management of ColdU involves a combination of protective measures against cold exposure and the use of anti-histamines to control disease activity. This retrospective study provides valuable insights into the clinico-epidemiological characteristics and treatment response of north Indian patients with ColdU.
ABSTRACT
Background There is scant data on basal cell carcinoma (BCC) in Indian patients. This retrospective study was conducted to explore epidemiology, risk factors, clinical and pathological aspects, and long-term treatment outcomes of BCC in a cohort of North Indian patients. Methods Data about patients registered in the dermatosurgery clinic between 01 January 2017 and 31 December 2022 with a confirmed diagnosis of BCC was collected. Results Among the 83 patients, 56.6% were females, and the median age was 62 years (6-85 years). Most patients (81.9%) had a single BCC lesion, resulting in a total of 126 assessed lesions. The median size of BCC at presentation was 1.90 cm, with nodular BCC being the most common histopathological subtype (39.7%). Head and neck region involvement was observed in 82.5% of patients, with the malar region, nose, and periorbital region being the most commonly affected sites. Pigmentation was clinically evident in 45.2% of cases. Surgical excision was the primary treatment modality (71.1% of patients). The median follow-up duration was 40 months (6-57 months). Recurrence occurred in five patients, with a longer disease-free survival period observed in the surgically treated group (55.58 ± 0.98 months) compared to patients treated with medical or destructive therapies (43.6 ± 3.482 months) (p = 0.003). Conclusion The data from this hospital-based study indicated a slight predilection for females among North Indian patients with BCC, with most cases occurring during their seventh decade of life. The condition commonly occurred on sun-exposed areas such as the malar region and nose, with a high percentage of pigmented lesions. Recurrence following surgical excision was rare, and overall treatment outcomes were favourable.
ABSTRACT
Pain is frequently encountered in dermatology practice, which impairs the activities of daily living, adds to psychological morbidity, and therefore compromises the quality of life. It ranges from mild to severe in intensity across various dermatoses and requires prompt addressal and treatment. Diseases such as extensive pemphigus vulgaris and Stevens-Johnson syndrome are especially painful and require a multidisciplinary approach with the involvement of a pain specialist in their management. The main pathogenic types of pain include visceral nociceptive, somatic nociceptive, and neuropathic types, the latter two being most relevant in dermatological disorders. Somatic nociceptive pain is often seen in patients of Stevens-Johnson syndrome/ Toxic epidermal necrolysis, epidermolysis bullosa, pemphigus vulgaris, erythema nodosum, and hidradenitis suppurativa, while neuropathic pain is part of the disease process in dermatoses like leprosy, herpes zoster, and dysesthesia syndromes. Therapeutic approaches to pain management include the use of non-opioids (acetaminophen, non-steroidal anti-inflammatory agents), opioids, and non-pharmacological therapies, along with appropriate management of the underlying dermatosis. World Health Organisation (WHO) analgesic ladder remains the most commonly employed guideline for the management of pain, although treatment needs individualisation depending on the nature and severity of pain (acute/chronic), type of dermatosis, and patient factors. There is a paucity of literature pertaining to pain management in dermatology and this topic is often neglected due to a lack of awareness and knowledge of the topic. The present review aims to discuss the pain pathway, various painful conditions in the setting of medical dermatology practice, and their management along with relevant pharmacology of the commonly used analgesics.
ABSTRACT
Folliculocystic and collagen hamartoma (FCCH) is a rare entity, typically documented in males with tuberous sclerosis complex. Here, we report a unique case of FCCH in a 19-year-old female with an unusual presentation in the external genitalia. The patient presented with a progressively enlarging mass over three years, causing difficulties in walking and sitting. Examination revealed a 10 x 15 cm tender, lobulated, skin-colored tumor with comedo-like openings originating from the right labium majus, with satellite lesions on both labia majora. She had no other symptoms or history suggestive of tuberous sclerosis. Histopathological examination showed dilated hair follicles with keratin, perifollicular fibrosis, and thick dermal collagen bands extending into subcutaneous tissue, confirming FCCH. This case underscores the importance of considering FCCH in the differential diagnosis of genital masses, even without classical clinical associations. Our findings contribute to the limited literature on FCCH and highlight the need for further exploration and awareness within the medical community.
ABSTRACT
Non-cultured epidermal suspension (NCES) is one of the most widely used surgical therapy for stable vitiligo patients in which recipient size preparation plays an important role in the outcome of NCES. The primary objective is to evaluate and compare the efficacy and safety of conventional suspension delivery after manual dermabrasion (CSMD) versus tattooing pen-assisted suspension delivery (TPSD) in NCES. Paired vitiligo units (VU) in 36 patients, matched with respect to size and location were divided into two groups. The VU in Group 1 underwent suspension delivery by CSMD while the VU in Group 2 underwent same by TPSD. All the VU were followed up at regular intervals until 24 weeks. At the end of 24 weeks, 31 VU (86.1%) in Group 1 achieved >75% repigmentation which was significantly higher (p = .02, chi-square test) as compared to 22 VU (61.1%) in Group 2. The color matching in both the groups VU was also comparable (p = .84, chi-square test). The patient global assessment (PGA) was significantly higher in Group 1 VU as compared to Group 2. Treatment response in terms of repigmentation and PGA was significantly better in VU treated with CSMD as compared to TPSD. Recipient site complications were seen more commonly in Group 1 VU as compared to Group 2. Perilesional halo at the recipient site was seen in none of the VU in Group 2 which was significantly lower than 6 VU in Group 1 than (p = .02, chi-square test). Better results may be possible with technical improvisations in tattooing pen needle diameter and depth of penetration.

Background Leprosy is known to be a great mimicker. Its dermatoscopic evaluation may be of value in establishing diagnosis. Objective To study the dermatoscopic findings encountered across the leprosy spectrum. Methods This was a multi-centre cross-sectional study of leprosy patients, where after a thorough cutaneous and neurological evaluation, representative skin lesions from the study patients were photographed in standard settings, and the most representative skin lesions were chosen for dermatoscopic evaluation. Data was entered in a structured proforma and a descriptive analysis of dermatoscopic patterns was carried out. Results A total of 53 cases of ages between 14 and 80 years, ranging from tuberculoid to the lepromatous spectrum of disease, with active skin lesions in the form of patches and plaques were included. The spectrum of leprosy as per Ridley-Jopling classification at diagnosis was indeterminate in 1 (1.9%), tuberculoid in 1 (1.9%), borderline tuberculoid in 25 (21.5%), borderline lepromatous in 9 (17%), lepromatous in 14 (26.4%) and histoid in 3 (5.7%). Dermatoscopic features included distorted pigment network in 48 (90.6%), focal white areas in 40 (75.5%), reduced eccrine and follicular openings in 43 (81.1%), widened skin lines in 28 (52.8%), circle hairs in 15 (28.3%) and white shiny streaks in 17 (32.1%). Conclusion Dermatoscopy is a practical, non-invasive device to assess skin lesions of leprosy and provide cues to its diagnosis, spectral classification and differentiating it from other granulomatous disorders. However, dermatoscopy alone cannot reliably differentiate between the various types of leprosy and future large-scale studies are required. Limitations of the study The numbers for each subtype were variable and few in some spectrum of leprosy patients. A dermatoscopic-histologic correlation was not done.
