Lymphocytic hypophysitis with involvement of the cavernous sinus and hypothalamus

Two cases of lymphocytic hypophysitis are reported, in which hypothalamic involvement causing diabetes insipidus was a prominent clinical feature. In one case, a man had clinical and radiological evidence of the involvement of the cavernous sinus. This represents the second reported case of a man with lymphocytic hypophysitis. A transsphenoidal biopsy established the diagnosis in both cases. Neither the involvement of the cavernous sinus nor permanent diabetes insipidus has been reported previously. A review of the literature is provided.     

Primary amyloidosis of ureter

Another case of primary isolated amyloidosis of the ureter is reported; we believe this is the seventeenth such case reported in the world literature. The previous cases are reviewed, and the clinical presentation and treatment are discussed. The importance of distinguishing the condition from transitional cell carcinoma of the ureter is emphasized and a conservative approach to surgical treatment is advocated.     

Giant Cell Tumor of the Larynx Treated by Surgery and Adjuvant Denosumab: Case Report and Review of the Literature

Giant cell tumor of the larynx (GCTL) is a rare entity; only 34 cases have been reported in the literature. We report a case of GCTL in a 46 year-old male presenting clinical, radiographic, histological and therapeutic features. Previously reported cases are also reviewed.     

Gastric diverticulum. A case report with long-term follow-up and a review of the literature

A rare case of symptomatic gastric diverticulum surgically managed is reported. The pathogenetic and clinical aspects of the disease are discussed and the usefulness of endoscopy as a means for differentiation between medical and surgical cases is stressed. A review of the literature is made and the conclusion is drawn that this uncommon pathology is often asymptomatic and requires surgical management only in complicated cases and in symptomatic patients that are not responding to medical treatment, as showed by the long-term follow-up (333 months) of the reported case.     

Ultrasound Findings of an Intratesticular Varicocele. Report of a New Case and Review of the Literature

The authors present a new case of intratesticular varicocele(ITV). The ultrasound findings on gray-scale and color Doppler imaging as well as the pertinent clinical manifestations are discussed. A review of the literature is also presented. According to our knowledge only 34 cases of ITV have been reported in the literature and the clinical significance of this lesion is not yet well established. This is the first reported case of infertility caused by a solely ITV, showing that the clinical implications of this entity may be more significant than previously thought.     

A case of hemangiomyoma of the ureter in a child

Herein a rare case of hemangiomyoma of the ureter in a child is reported. Benign mesodermal tumors of the ureter are not common, particularly in a child. Two cases of leiomyoma of the ureter in childhood have been reported to date. This is the first case of ureteral hemangiomyoma in a child. Nephroureterectomy was performed and the subsequent clinical course reveals no evidence of recurrence.     

Periosteal chondroma of the cervical spine: one more cause of neural foramen enlargement

A case of cervical periosteal chondroma presenting with an enlarged neural foramen is described. Review of the literature showed that cervical chondromas are rare but that their characteristic clinical and computed tomographic findings aid in their diagnosis. The computed tomographic findings of two previously reported cases of cervical periosteal chondroma resembled those of the present case. On computed tomographic scanning, an iso-or high-density mass containing stippled calcifications and originating in a posterior cervical neural arch was observed in all three cases. Extensive spinal canal and extradural involvement was observed in five of the seven reported cases, including the one reported here.     

Congenital calcification of the larynx and trachea

The fifth case of diffuse laryngeal and tracheal cartilage calcification in infancy is reported. The previously reported cases are briefly described. Differential diagnosis and potential etiologies are discussed. It is thought that these patients represent a rare but distinct clinical entity.     

Carcinoid Tumor of the Kidney Presenting as a Large Abdominal Mass: Report of a Case

Carcinoid tumors are known to occur frequently in the gastrointestinal tract and they can develop in nearly every organ system. However, a carcinoid tumor of the kidney is an extremely rare entity and only 38 cases have been reported in the English literature. We herein describe the 39th case of primary renal carcinoid tumor, found in a young Japanese woman 2 months after delivery. The pathologic similarities of our case with those of previously reported cases are briefly reviewed together with some aspects of clinical features and prognostic factors of this rare disease.     

Lipoma of the esophagus—Report of a case and review of the literature

We report herein, a rare case of esophageal lipoma and review the Japanese literature on this subject. Lipoma of the alimentary tract is relatively uncommon but that of the esophagus is extremely rate with only 17 cases having been reported in Japan. The majority of these cases occurred in the cervical esophagus with the most serious symptom being regurgitation of the pedunculated tumor which lead to asphyxia and death in one case. Only 2 cases occurred in the thoracic esophagus and these tumors were small in size and resected endoscopically. This is the first reported case of an esophageal lipoma being located in the thoracic esophagus which was resected through a thorocotomy. The clinical features of esophageal lipoma are also described herein.     

Malignant Rhabdoid Tumor of the Floor of Mouth: First Reported Case in the Oral Cavity of an Adult

Malignant rhabdoid tumors (MRTs) are exceedingly rare lesions. To our knowledge, only 2 cases have been reported in the oral cavity, with both examples occurring in infants. The current case is the third reported case of MRT of the oral cavity and the first reported case to occur in an adult at this location. The following report describes the clinical, histologic and immunohistochemical features of this tumor.     

Lipoma of the esophagus--report of a case and review of the literature

We report herein, a rare case of esophageal lipoma and review the Japanese literature on this subject. Lipoma of the alimentary tract is relatively uncommon but that of the esophagus is extremely rare with only 17 cases having been reported in Japan. The majority of these cases occurred in the cervical esophagus with the most serious symptom being regurgitation of the pedunculated tumor which lead to asphyxia and death in one case. Only 2 cases occurred in the thoracic esophagus and these tumors were small in size and resected endoscopically. This is the first reported case of an esophageal lipoma being located in the thoracic esophagus which was resected through a thorocotomy. The clinical features of esophageal lipoma are also described herein.     

Malignant rhabdoid tumors of the central nervous system. Report of a case

Primitive malignant rhabdoid tumor of the central nervous system are extremely rare. Less than 70 cases are reported in the literature. This tumor grows during the first months of life and prognosis is very poor. We report a case of primitive malignant rhabdoid tumor in a 17-year-old young adult. To our knowledge it is the first such case reported in the literature. We review the clinical feature, the neuradiological and therapeutical aspects.     

Leiomyoma of the ureter

We report a case of leiomyoma of the ureter, and the patient underwent partial ureteral resection. This is the 8th case reported after 1955, and the clinical features of ureteral leiomyomas of these 8 cases are discussed.     

Rupture of all digital flexors following Colles' fracture

Flexor tendon rupture following a Colles' fracture is a rare complication with only a handful of cases reported since the initial report in 1932. We present a case in which all digital flexor tendons ruptured within 6 months of a Colles' fracture. Previous reported cases have demonstrated rupture of either the radial or ulnar digital flexors but this case is the first in which all the digital flexors have been involved. This case report highlights the clinical implications of this rare occurrence and stresses the importance of accurate reduction and thorough clinical examination following bony injuries to the wrist.     

Xanthogranulomatous pyelonephritis: a report of 2 cases.

Two cases of xanthogranulomatous pyelonephritis are reported in Negroes. The clinical findings are similar to those in previously reported cases. In 1 case nephrolithotomy was followed by the development of a perinephric abcess 8 months later. Late diagnosis has limited experience with more conservative management, which should be reserved for demonstrably focal disease.     

Aneurysm of pancreaticoduodenal artery: report of a case and review of the literature

Aneurysms of the pancreaticoduodenal artery are uncommon. Only 24 cases have so far been reported. A case of clinically unsuspected, fatally ruptured pancreaticoduodenal artery aneurysm in a 64-year-old man with a five-day history of mild epigastric pain is reported. A review of the literature and brief discussion of etiologic factors and clinical presentations are also included.     

Leiomyosarcoma of inferior vena cava

A case of leiomyosarcoma of the inferior vena cava is presented and pertinent clinical features of 57 reported cases in the English literature are reviewed.     

Congenital absence of intestinal smooth muscle: a case report and review of the literature

Herein is reported case of an otherwise healthy full-term infant girl who presented with numerous spontaneous intestinal perforations with congenital absence of intestinal muscularis mucosae and muscularis propria. Few other cases are reported in the English literature with varying presentations. We review those cases, theories of pathogenesis, embryology, and possible connections to various clinical presentations.     

Isolated olfactory groove neurilemmoma.

A case of neurilemmoma arising from the olfactory groove presenting with headache, vomiting, and visual impairment in a thirty-seven-year-old man is reported. His clinical manifestations are described, with a brief review of three other cases reported in the literature so far.
