A case report on malignant cylindroma over nape of neck

Cylindromas are uncommon adnexal tumors that exhibit eccrine or apocrine differentiation and usually follow a benign, slow-growing course. They most often occur in the head and neck region and may present as isolated sporadic lesions or as multiple tumors associated with inherited syndromes. Malignant transformation is rare, particularly in solitary lesions. We report a rare case of malignant cylindroma arising over the nape of the neck in a 60-year-old woman with a long-standing swelling that recently developed ulceration and discharge. This case underscores the importance of careful assessment of long-standing adnexal tumors that demonstrate new or atypical clinical features, as these changes may indicate malignant transformation.
