RESUMEN
Background: Frontal fibrosing alopecia (FFA) is an important cause of scarring alopecia seen mostly in post-menopausal women but sometimes in pre-menopausal women and men. Although considered a variant of lichen planopilaris due to its histopathological characteristics, it has distinct clinical features and associations, which make it a unique entity. We hereby report a series of patients with FFA from North-East India. Aims and Objective: This study aimed to analyse the clinical and histopathological characteristics of FFA. Materials and Methods: We retrospectively analysed clinical records and histopathological features of FFA cases diagnosed in the Dermatology Outpatient Department from April 2013 to February 2023. Results: A total of 21 patients, who were diagnosed with FFA from April 2013 to February 2023, were analysed. Of these, 19 patients were female, with a male-to-female ratio of 9.5:1. The mean age of study population was 48.33 years. The majority of the patients were from the post-menopausal age group (15/19 females, 78.94%). Lichen planus pigmentosus (6, 28.57%) was the most commonly associated disease, followed by androgenetic alopecia and lichen planopilaris (2 each, 9.52%). The main histological features noted were perifollicular lymphocytic infiltrate in 18 (85.71%), followed by hydropic degeneration of basal follicular keratinocytes in 15 (71.42%) and melanin incontinence in 14 (66.66%) patients. Conclusion: Our study is the first study from North-East India focusing on the clinical presentation and histopathological characteristics of FFA. Furthermore, with respect to the recent development in FFA, our study attempted to determine the clinical significance of the proposed criteria for the diagnosis of FFA patients by Tolkachjov et al. (2018), viz. International FFA Cooperative Group Criteria (2021).
RESUMEN
Context: Dermatoscopy has been used recently for identifying the specific features of onychomycosis. Very few studies have used it as a diagnostic tool. Our study highlights the specific patterns in different clinical types of onychomycosis and the novel features that have never been reported previously. Aims: To study the dermatoscopic patterns in patients with onychomycosis and determine the sensitivity, specificity, positive, and negative predictive values of the different features. Study Design: A cross-sectional study. Materials and Method: Dermatoscopic picture using dinolite video dermatoscope was taken in patients diagnosed with onychomycosis either with a positive KOH, culture, and/or PAS. Result: A total of 80 patients were included. Onychomycosis was identified in 68 individuals. Clinically, 73.52% presented with distal lateral subungual onychomycosis (DLSO) and 26.47% had total dystrophic (TD). PAS was positive in 85.29% of patients, KOH in 75%, and culture in 66.17%. Trichophyton species were isolated in 53.33%, whereas Candida species in 40% of patients. Dermatoscopic features were seen in all 68 patients (100%). The most common finding in decreasing order includes spike pattern, ruin appearance, distal irregular terminations (DIT), longitudinal striations, chromonychia, focal homogeneous opacities, microsplitting, and uniform homogeneous pattern. Three novel patterns were observed: homogeneous opacity with a-z pattern border, microsplitting in a Christmas tree pattern, and focal homogeneous opacities. Conclusion: To our knowledge, this is the first study conducted in northeast India where dermatoscopy was used as a diagnostic tool and it was found to have the highest sensitivity. New features that have not been described before have been identified.
RESUMEN
Various dermatological manifestations have been observed in patients with Coronavirus disease (COVID-19) infection ranging from maculopapular rashes, urticaria, chickenpox-type lesions, chilblain-like, distal-limb ischemia, and livedo racemosa. While most of these cutaneous findings are self-resolving, they may aid in the timely diagnosis of this infection. We are reporting three patients presenting with dermatological features resembling (i) varicella zoster, (ii) herpes labialis, and (iii) Steven Johnson Syndrome (SJS) who were subsequently diagnosed with Covid-19 infection. The skin lesions disappeared after successful treatment of Covid-19.
RESUMEN
Localized myxedema is most commonly described in patients with hyperthyroidism, especially Graves' disease. Although pretibial myxedema generally appears as indurated plaques on the shins, it has also been rarely reported in other areas such as the face, shoulders, arms, and abdomen. We report a rare case of preradial myxedema in a hyperthyroid patient who was taking thyroxine post thyroidectomy for goiter. To the best of authors' knowledge, this is the first case of preradial myxedema, due to long-term intake of thyroxine, reported in the English dermatological literature.
RESUMEN
Primary localized cutaneous amyloidosis refers to a group of disorders characterized by deposition of amyloid in the dermis without any systemic involvement. It comprises the following clinical types: macular, lichenoid, nodular, and biphasic. There are also rare variants such as amyloidosis cutis dyscromica and poikiloderma-like cutaneous amyloidosis. We report a case of primary cutaneous amyloidosis in a 17-year-old boy with unusual pigmentation of various patterns (reticulate and diffuse pigmentation with mottling and rippling at places) and hypopigmented atrophic macules. Our patient also had nail, oral, and mucosal pigmentation that have not been described. Amyloid deposits were shown histopathologically in both hyperpigmented and hypopigmented macules.
