Parasitic myomas, defined as extrauterine seeding of leiomyoma, have been reported since the early 1900s. These myomas were thought to be spontaneously occuring, separate from the uterus but still hormone-dependent and can cause symptoms. What seemed to be a rare disorder developing from the natural history of pedunculated myomas has ...

Primary testicular leiomyosarcoma is an uncommon tumor with only few cases described in literature. In young people this rare tumor seems to be related to radiotherapy and anabolic steroids abuse. In older people there are apparently no risk factors. We describe one further case in a 77-years old man with ...

Leiomyosarcomas of the ovarian vein are extremely rare tumours. Most tumours are hypervascular and typically have a large avascular centre of necrosis. We experienced a case of a retroperitoneal leiomyosarcoma that arose from the ovarian vein with marked vascular proliferation and dilatation within the tumour. To the best of our ...

Primary leiomyosarcoma of the testis is an extremely rare disease entity of the genito-urinary tract. Although its clinical presentation does not seem to differ from that of other testicular malignancies, the clinical stage with which patients have been treated, as reported in contemporary literature, has always been stage 1. Diagnosis ...

Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Retroperitoneal teratomas are rare and present challenging management options. We report here the case of a histologically unusual retroperitoneal tumor detected on computed tomography during the workup of abdominal ...

Intrapericardial teratomas are rare but potentially fatal. With prenatal ultrasound, early diagnosis and decision for treatment can be accomplished. However, the decision becomes to treat prenatally vs. waiting until the neonatal period for definitive surgical management. The most common sequelae of intrapericardial teratomas are pericardial effusion and often progression to ...

Benign endobronchial polyps are rare findings that present a diagnostic dilemma not only for the clinician but also for the pathologist. We describe a man with repeated visits to emergency departments for coughing spells who ultimately underwent bronchoscopy and biopsy. The biopsy specimen was initially diagnosed as a leiomyoma, but ...

CONTEXT: Leiomyosarcoma most commonly involves the female genital tract and occasionally arises within the retroperitoneum, abdominal cavity, or the soft tissues of the extremity. Presentation as a primary bone tumor is extraordinarily uncommon, potentially leading to misdiagnosis. The prognosis is traditionally thought to be dismal. However, this conclusion is largely ...

Teratomas are tumors that are derived from two or three of the primordial germ layers: ectoderm, mesoderm and endoderm. They arise most commonly in a midline or paraxial location from the brain to the sacral area and are most often located in the sacrococcygeal region. Head and neck teratomas are ...

Retroperitoneal teratoma with malignant transformation is a rare condition in adults. Its most common malignant transformation is into a squamous cell carcinoma, but rarely into a mucinous adenocarcinoma. Postoperative treatment of mucinous adenocarcinoma arising from teratomas has not been established due to its rare incidence. Here we present a case ...

We present two cases of clinically extensive bilateral DVTs associated with inferior vena caval thrombosis. Young patients presenting with symptoms of DVT should be investigated not only to establish any thrombophilic pre-disposition, but to ascertain the proximal extent of thrombus which may itself influence treatment.

The occurrence of leiomyoma of the rectum is uncommon. Most of these lesions are clinically silent and are found incidentally during laparotomy or endoscopic procedures for unrelated conditions. Symptomatic leiomyomas of the rectum are encountered less frequently, with only sporadic reports in the literature. We describe a case of a ...

We report a mature solid teratoma of the fallopian tube in an elderly woman. This mass was noted on CT scan and considered metastatic in nature since following a bioptical diagnosis of endometrial adenocarcinoma. Hysterectomy and bilateral salpingectomy and ovariectomy were performed and a second minor mature solid teratoma was ...
