Abstract

The etiologies of vulvar nodules range from infectious to neoplastic. Owing to the wide spectrum of vulvar diseases, clinical differentiation of the lesions is crucial for adequate diagnosis and management. A 46-year-old patient presented with a nodular lesion in the vulvar region that had been growing slowly for 10 years. Gynecological examination revealed the presence of a solid nodular lesion measuring approximately 3 cm in the middle third of the right labia majora without phlogistic signs or secretion discharge. The lesion was excised and an anatomopathological study revealed a nodular hidradenoma. Nodular hidradenoma is a rare benign neoplasm of the apocrine glands that mainly affects women between 30 and 60 years of age. Although generally asymptomatic, some symptoms have been described, such as itching, pain, ulceration, or secretory discharge. The diagnosis was made by an anatomopathological study, and treatment consisted of total excision of the lesion without the need to enlarge the margin. During the investigation, malignant lesions such as liposarcoma of the vulvar region and non-melanoma skin cancers were excluded. Differential diagnosis is important because it requires a more invasive approach and surgical margins. This report aimed to expand the knowledge of the diagnosis of vulvar hidradenoma to exclude the possibility of malignant neoplasia while caring for vulvar nodules, thereby allowing proper management of the case.
