Nodular lepromatous leprosy, an atypical and advanced manifestation of lepromatous leprosy, constitutes a significant clinical and diagnostic challenge in the dermatologic disease landscape. In the present study, a comprehensive and multidimensional inquiry of this leprosy variant is undertaken to provide an enriched understanding of its clinical phenotype and underlying pathologic profile. This article is based on a prospective investigation involving a series of patients with nodular lepromatous leprosy, in which detailed clinical, histopathological and immunohistochemical analyses were performed. Through the integration of clinical findings with microscopic evaluations, the distinctive features of this nodular form are delineated, highlighting its diversified clinical presentation, which may include cutaneous nodules, peripheral nerve involvement and advanced systemic dissemination. Histopathological analysis highlights the diffuse infiltration of infected Schwann cells in the dermal nodules, as well as Langerhans cell hyperplasia and intense inflammatory response. In addition, immunohistochemical implications are explored, revealing increased expression of inflammatory markers and the involvement of immunomodulatory cells in the pathogenesis of the disease. Overall, this article seeks to fill the gap in the medical literature regarding nodular lepromatous leprosy by providing a comprehensive and up-to-date assessment of its clinical presentation and pathologic basis. The information derived from this study may not only enrich the current understanding of lepromatous leprosy as a whole, but also guide future research toward more precise and personalized therapeutic approaches for this particular clinical variant.
