  • Title: Arborizing vessels under dermoscopy: a case of cellular neurothekeoma instead of basal cell carcinoma.
    Author: Aydingoz IE, Mansur AT, Dikicioglu-Cetin E.
    Journal: Dermatol Online J; 2013 Mar 15; 19(3):5. PubMed ID: 23552002.
    Abstract:
    Neurothekeoma is a slow-growing, benign tumor of nerve sheath origin. Herein we present a 62-year-old female who presented with a 5-month history of a nodule that had shown a slight enlargement. She had a diagnosis of non-Hodgkin lymphoma for 10 years for which she had received multiple sessions of chemotherapy and radiotherapy. Cutaneous examination showed a well-defined, firm, 2 cm, pink-red nodule of the right supraclavicular area, which showed thick and arborizing vessels under dermoscopy. A diagnosis of cellular neurothekeoma was made after histopathologic examination with immunohistochemistry. Thick and arborizing vessels have been described as the dermoscopic hallmark of nodular and cystic basal cell carcinoma. In the past, hydradenoma and intraepidermal poroma have been defined as dermoscopic mimics of basal cell carcinoma because of the characteristic appearance of arborizing vessels. With this report a neurogenic tumor has been added to this list.
