ABSTRACT
Introduction: Hyperpigmentation is one of the most common reac?on to inflammatory, benign and malignant lesions of the skin. These disorders comprise heterogeneous group of diseases of epidermal and dermal hyperpigmenta?on divided into various types according to e?ology and pathology. Correct diagnosis of these hyperpigmented lesions is linked to histopathologic examina?on of skin biopsies with clinical correla?on. Aim: To study the spectrum of hyperpigmented skin lesions with reference to age and sex distribu?on. Materials and Methods: This prospec?ve cohort study was conducted at Department of Pathology, at Alluri Sitaramaraju Academy of Medical Sciences, Eluru, Andhra Pradesh, India, which included 80 pa?ents who were clinically diagnosed with hyperpigmented skin lesions in all age groups from July 2014 to August 2016. Frequency and percentage sta?s?cs was used to present the results. Results: Out of 80 cases, 34 cases of inflammatory lesions, 23 cases of benign lesions and 23 cases of malignant lesions were reported. Among the post inflammatory lesions the majority were classical Lichen planus. Conclusion: Most common lesion was lichen planus and its variants with highest incidence in females and age group greater than 60 years. Histopathological diagnosis with clinical correla?on aids in effec?ve management of the pa?ents.
ABSTRACT
Este estudo apresenta achados microscópicos do nevo pigmentado de células fusiformes, designado como nevo de Reed, os quais resultaram de exames microscópicos realizados em múltiplos cortes de lesão de pele. Apresenta ainda a revisão de literatura pertinente. Os achados clínicos e microscópicos são consistentes com os dados da literatura descritos, originariamente, por Reed e colaboradores. O nevo de Reed é uma lesão melanocítica benigna, que, no entanto, pode ser equivocadamente identificada como um melanoma malígno. As lesões melanocíticas que podem ser confundidas com melanoma malígno devem ser avaliadas cuidadosamente, a fim de obter-se um diagnóstico acurado, e seguir-se a conduta pertinente.
This paper presents the findings of microscopic studies of the PigmentedSpindle-cell Nevus, called Nevus of Reed, carried on multiple sections of skin lesion. It presents, as well, a review of the related literature. The clinical andmicroscopic findings coincide with those originally described by Reed andcolleagues. The Nevus of Reed is a benign melanocytic lesion, which, however,can be easily misdiagnosed as a malignant melanoma. Therefore, in case of suchlesions, all efforts should be made to render an accurate diagnosis, and thus, toprovide the adequate therapy.
