A 23-year-old man with a right scrotal mass and back pain was referred for further treatment after right radical orchiectomy for testicular cancer. CT scans brought by the patient showed extensive metastasis to the retroperitoneal lymph nodes with no lung involvement. α-Fetoprotein and human
A 17-year-old male patient presented to the clinic with a headache, nausea, and vomiting. Magnetic resonance imaging demonstrated a fat-containing and -enhancing heterogeneous tumor in the third ventricle, and fat droplets within the ventricles and the subarachnoid space. Obstructive hydrocephalus
BACKGROUND
Intracranial teratomas account for 0.5% of all intracranial tumours and 2-4% of intracranial tumours in children. However, in terms of tumours of the pineal area, the exact incidence is not ascertained. Although, it is noted that 50-60% of central nervous system (CNS) germ cell tumours
Ovarian torsion is a well-known but poorly recognized disease. Although ovarian torsion is the most common complication of ovarian tumors in children, it is an uncommon cause of abdominal pain in pediatric patients. Ovaries can be only salvaged by prompt diagnosis and timely surgical intervention.
A 3-year-old boy had a history of nausea and vomiting for 1 month. After two episodes of tonic cramp, he became drowsy and then semicomatous. Physical examination on admission revealed a dehydrated semicomatous boy with fixed, dilated pupils of equal size, horizontal nystagmus, and left hemiparesis
Benign cystic teratomas are the most common ovarian neoplasms in women. Teratomas are usually benign, unilateral, and most often found in young and premenopausal women. Most are 5 cm to 10 cm in diameter when diagnosed, and on sectioning, they usually contain thick sebaceous material, tangled hair,
A 16-year-old girl with no prior medical history developed vertigo and nausea following alimentary infection. Neurological examination showed limb and truncal ataxia, opsoclonus, myoclonus, and hyperreflexia. Brain magnetic resonance imaging and cerebrospinal fluid analysis showed no abnormalities.
Intracranial mature teratomas have good prognoses and are usually treated by total tumor resection. We report a rare case of a germinoma that occurred 11 years after total removal of a pineal mature teratoma. A 5-year-old boy presented with headache and nausea and was diagnosed with a pineal tumor
UNASSIGNED
The hallmark of gestational trophoblastic disease is the production of human chorionic gonadotropin (hCG) due to the hyperproliferation of extraembryonic trophoblast cells. Previous studies show hCG has thyrotropic action due to its structural similarity with thyroid stimulating hormone
A teratoma is a germ cell tumor that is composed of tissue derived from two or three germ layers. Duodenal teratomas are extremely rare and have been exclusively reported in neonates and children. This is the third case of a teratoma primarily arising in the duodenum and the first case BACKGROUND
Primary mature solid teratomas of the fallopian tube are extremely rare and only 11 cases have been reported in the literature. A woman presented with a mature, solid teratoma of the fallopian tube, possibly the largest solid teratoma on record.
METHODS
A 24-year-old, nulliparous woman
Benign cystic tumors, specifically dermoid or mucinous cysts, are the most frequent causes of ovarian torsion. In clinical practice, adnexal torsion is usually subjected to adnexectomy to prevent embolism of thrombosed ovarian veins and its sequelae. However, this intervention is unsatisfactory for
A 67-year-old uniparous woman had undergone surgery for acute perforated gastric ulcer 10 years prior to the current presentation. Although abdominal computed tomography (CT) performed at that point had revealed a mature cystic teratoma measuring 6 cm in diameter in the right ovary, it was left
Intracranial fat-containing congenital tumors are characterized by negative absorption values on computed tomography (CT). We are reporting a case of teratoma with intraventricular free fat diagnosed preoperatively by CT. The case is a 19-year-old female who was admitted to our hospital because of
Mature cystic teratomas (dermoid cysts) are the most common germ cell tumours with 10-25% incidence of adult and 50% of paediatric ovarian tumours. The aetiology of dermoid cysts is still unclear, although currently the parthenogenic theory is most widely accepted. The tumour is
