Clinico-Etiological Description of Annular Skin Eruptions
Keywords:Annular skin eruptions
AbstractBackground Annular skin eruptions are figurate lesions characterized by a ring-like morphology. The lesions may appear as circular or ovoid macules, patches, or plaques with an erythematous periphery and central clearing. Objective The aim of this study is to determine the etiology of annular skin lesions in patients attending to the Dermatology Center/ Baghdad, Iraq. Methods This study was conducted on 242 patients who visited the dermatology department in Baghdad, Iraq, throughout the time period with annular skin eruptions. It is an observational, descriptive, cross-sectional study (from February 2020 to September 2021). If necessary, a thorough history, clinical exams, investigations, and biopsy were performed. Results The sample included 242 patients; there were 95 males and 147 females. Mean age ±SD = (31.57±16.07) years. The disease duration ranged from one week to more than six months. The most common disease was dermatophytes (72%), followed by erythema multiforme (3.8%), annular psoriasis(2.9%), Nummular eczema (2.9%), annular lichen planus (2.4%), while porokeratosis was(2.4%). KOH examination done to all cases suspected to be fungal and it was positive only in 3 cases. Itching was the main symptom in dermatophytosis. There is a statistically significant link between dermatophytosis, gender, and itchiness. Conclusion The annular disease was more common in middle-aged females. The majority of annular lesions were dermatophytosis. Surprisingly three diseases, erythrasma, leishmania, and plane wart, presented as annular lesions in this study.
