Teratomas are rare germ cell tumors usually found in the gonads. Extra-gonadal teratomas are especially rare, mostly occurring in the thorax. Only a few cases of intrathoracic teratomas have been reported in medical literature and most reported were located in the mediastinum. An additional intrathoracic location for teratoma occurrence is in the pulmonary system, most commonly in the upper lobe of the left lung. In this report, we describe a case of a 35-year-old woman diagnosed with an intrapulmonary mature teratoma found in the right upper lobe. A 35-year-old Saudi female presented with a chief complaint of a three-week history of dry cough. Chest X-ray revealed a right-sided para-pericardial mass in the anterior mediastinum and a significant decrease in the size of the right middle lobe opacity. Subsequently, a chest computed tomography (CT) was performed and revealed a cystic mass in the right lung, which required removal by surgical intervention. The surgery was performed via a thoracoscopic approach and the tumor was excised with no complications. Intrapulmonary teratomas (IPT) usually present with vague and non-specific symptoms such as cough, hemoptysis, and chest pain. It is a rare condition without diagnostic features detected preoperatively, save for trichoptysis which is reported in approximately 13% of the cases. We report a rare appearance of mature IPT in the right upper lung zone which is an unusual location.

Background: Acne is a widespread and complex skin disease among developed nations, affecting nearly all young adults between the ages of 15 to 17 years. It is a chronic inflammatory skin disorder resulting in psychological stress. Historically, the relationship between diet and acne is controversial. As a result, significant studies have been done to evaluate this relationship. Assessment of these literatures will help to provide better outcomes for the patients.Objective:This study aims to: 1-Measuring effect of diet and nutritional substances in the management and prevention of acne vulgaris. 2-Providing a reference paper analyzing all the clinical studies in this field. 3-Analyzing the last progression has been reached. Methods: PubMed database was used for articles selection. We included all relevant articles to our review with the following topics (("Acne Vulgaris/diet therapy"[Mesh]) AND ("Acne Vulgaris/prevention and control"[Mesh])) AND ("Acne Vulgaris/therapy"[Mesh]). We excluded other articles which are not related to this field. The data will be extracted according to specific form in which it is going to be reviewed by group members to assess the dietary effect of nutritional substance on acne vulgaris. Conclusion:We concluded that there are studies that showed promising results among patients and proved that associations do exist. Nevertheless, further studies with bigger sample and better protocols are needed to establish a concrete evidence-based relationship.
