Pulmonary Metastasis in Infantile Choriocarcinoma: Successful Outcome
Kartal, Ibrahim; Dagdemir, Ayhan; Elli, Murat; Bilgici, Meltem Ceyhan (Springer India, 2018)Infantile choriocarcinoma is usually fatal without appropriate treatment. A 3-month-old boy who presented with respiratory distress, hepatomegaly, amemia and bilateral nodular lesions on chest X-ray. Fine-needle liver ... -
A Skeptical Approach to the Management of Persistent Oral Ulceration in a Child
Kartal, Ibrahim; Dagdemir, Ayhan; Elli, Murat; Yildiz, Levent; Yilmaz, Aysegul (Hindawi Ltd, 2018)The diagnosis of oral lesions is sometimes difficult due to both the clinician's limited experience with the conditions that may cause the lesions and their similar appearances, especially in children. Correctly establishing ... -
