    Clinicopathological Evaluation of Childhood Sacrococcygeal Germ Cell Tumors: A Single-Center Experience
    (2022) Hasbay, Bermal; Canpolat, Tuba; Aktekin, Elif; Ozkan, Hasan; Kekec, Senay Demir; 35781237
    Objective: We aimed to evaluate the cases of sacrococcygeal germ cell tumors diagnosed in our hospital between 2006 and June 2021. Materials and Methods::We evaluated 38 sacrococcygeal germ cell tumors cases in our series in terms of age, sex, clinical complaints, localization, macroscopy, tumor size, histopathological diagnosis, surgical, postoperative complications, treatment, recurrence, and prognosis. Results: The cases ranged from 1 day to 16 years of age; 14 cases were diagnosed with routine ultrasonographic examination during prenatal period while the rest of the cases most frequently presented with complaints of constipation. In terms of localization, 6 cases were type 1, 11 cases were type 2, 6 cases were type 3, and 15 cases were type 4. In the pathological evaluation, 25 cases were mature teratoma, 8 cases were immature teratoma, and 5 cases were pure yolk-sac tumor. In terms of complications, temporary colostomy was performed as a result of rupture during birth in 2 cases, disseminated intravascular coagulation at birth in 1 case, and colon injury in 2 cases. There was a recurrence in 2 of our cases. Thirty-seven of our cases were alive and 1 died. Alpha-fetoprotein level was high in 28 of our cases. Conclusion: In our series, type 4 cases were observed more frequently, contrary to the literature. We recommend to use a routine ultrasonography to patients who come to the clinic with complaints of constipation and inability to urinate and if a mass is detected, asking for alphafetoprotein for further follow-up. Sacrococcygeal germ cell tumors are ultimately a disease that can be successfully treated with multidisciplinary approach, accurate diagnosis in the antenatal and postnatal period, appropriate surgical intervention, and regular follow-up.

    Parotid gland tuberculosis accompanied by brucellosis
    (2021) Inan, Serhat; Caylakli, Fatma; Canpolat, Tuba; 0000-0002-7333-2896; 0000-0001-8821-4481; AAP-7195-2020; AAJ-1407-2021
    Almost one-fourth of the world's population is latently infected with Mycobacterium tuberculosis (MTB) with approximately 3% to 15% people at risk of progression to active disease during their lifetime. Parotid gland tuberculosis (TB) is an extremely rare form of extrapulmonary TB even in endemic areas. Parotid gland TB presents clinically as a unilateral, slow-growing, and possibly painless mass. Parotid gland TB tends to mimic parotid tumors without pathological evaluation. Risk factors for active infection in extrapulmonary TB forms are human immunodeficiency virus, malnutrition, diabetes mellitus, smoking, alcoholism, hematological malignancies, and immunosuppressive treatments. Brucellosis is a systemic disease that is transmitted from unpasteurized milk and dairy products obtained from an infected animal. It can affect many organs. Brucellosis is difficult to diagnose because its signs and symptoms are nonspecific and mimic many diseases. The aim of this case report is to present the clinical features, pathophysiology, diagnostic process, and treatment of a parotid gland TB case accompanied by brucellosis, the diagnosis and treatment of which were based on the suspicion of the clinician, in the light of the literature.
