Cutaneous Lymphadenoma: A Rare Differential Diagnosis of Basal Cell Carcinoma. Case Report

Abstract

Cutaneous lymphadenoma is an uncommon benign tumor originating from hair follicles, typically presenting as a nodular lesion in sun-exposed areas. This can lead to confusion with other more aggressive conditions, such as nodular basal cell carcinoma. Its differential diagnosis is challenging due to its distinct histological features, which include a pattern of epithelial cells resembling ameloblastoma within a dense stroma. Nevertheless, this tumor has a benign behavior and carries an excellent prognosis. Early diagnosis and complete surgical excision are key for proper management, with a low recurrence rate. We present the case of a 64-year-old female patient with an asymptomatic nasal nodule, which was biopsied and diagnosed as adamantinoid trichoblastoma, followed by complete excision. It is essential for physicians to be familiar with this entity to avoid misdiagnosis and unnecessary patient anxiety.
