Does Radiolucency in the Posterior Mandible below the Mandibular Canal Signify a Stafne Cyst — A Rare Case Report With a Diagnostic Challenge

Abstract Background Yolk sac tumor (YST) is a germ cell tumor. It is primarily located in the gonads but can also occur extragonadally (extragonadal yolk sac tumor - EGYST), most commonly in the pelvis, retroperitoneum or mediastinum. Only a few YSTs of the urachus have been described. Case report We present a rare case report of a 37-year-old male with episodes of macroscopic hematuria. The histological specimen obtained by transurethral resection showed a solid, and in some parts papillary infiltrative, high-grade tumor with numerous areas of marked nuclear atypia and clear invasion between the detrusor bundles. Glandular pattern has been observed in only minority of the tumor. Immunohistochemistry showed significant positivity for GPC3, SALL4 and cytokeratins AE1/AE3, while KRT7 and GATA3 were negative. We concluded that the biopsy findings were consistent with urothelial carcinoma with infrequent YST differentiation. In definitive surgical specimens we found a malignant epithelial, glandular and cystically arranged tumor of germinal appearance arising from urachus. The surrounding urothelium was free of invasive or in situ tumor changes. We reclassified the tumor as a urachal YST. Conclusion EGYST was suspected because glandular and hepatoid structures were found, but the presence of these structures should be verified by immunohistochemistry.

Buergers disease or Thromboangiitis obliterans is a segmental inflammatory disease that affects the vessels and nerves of the extremities. It usually affects men below 45 years old and correlates with tobacco, as a predisposing factor. A young adolescent boy of 18 yrs, smoker, nonalcoholic, nondiabetic was presented with the complaints of progressive aching pain (Claudication pain) during walking in both legs which relives by taking rest for last 3 years and also suffering from long standing non healing ulcer in the right great toe and second toe following traumatic nail avulsionBirdem Med J 2015; 5(1): 37-41

Malignant Lesions

Cases of renal leiomyomas are fewer than 100 in the literature and therefore possess a diagnostic challenge.1 By definition, leiomyomas are benign soft tissue neoplasms.2 that arise from smooth muscle cells.3 The most common sites of origin are the uterus, intestines and skin.4 One of the more unusual types of leiomyomas are the ones arising from the kidneys. They account for about 1.5 % benign lesions of kidneys.5 The methods of detection are through discovery during autopsy, incidental discovery during imaging or by clinical diagnosis in symptomatic lesions.6 Prevalence based on incidental finding at the time of autopsy is 4.2 - 5.2 %.7 Creating a differential diagnosis between leiomyomas and other malignant lesions is only possible by histopathological examination.8 We hereby report a case of 26-year-old female who presented with pain in abdomen and on histopathological examination was diagnosed as a case of renal leiomyoma.
