Epidermoid cyst of the scrotum: a case report

A 52-year-old male visited our department for a painless swelling from the right side of the anus to the right scrotum that he first noticed 5 years earlier. Palpation revealed a small fist-sized elastic solid mass with a smooth surface from the central area to the inferior pole of the right scrotum. This mass was clearly demarcated from the contents of the scrotum and not adherent to the scrotal skin. A diagnosis of a tumorous lesion in the scrotum was made, and the tumor was resected. Histopathological examination demonstrated a scrotal epidermoid cyst. To our knowledge, this is the 17th case reported in Japan.     

Spontaneous rupture of splenic hemangioma: a case report

Splenic hemangioma is rare. The major problem concerning splenic hemangioma is the difficulty of preoperative diagnosis. No characteristic signs allow the specific diagnosis of this tumor. Spontaneous rupture is the main complication, occurring in up to 25% of cases reported. In cases of rupture of the tumor, splenectomy is a life-saving and mandatory procedure. A case of spontaneous rupture of splenic cavernous hemangioma is presented and the literature is reviewed.     

Smooth-muscle hamartoma of the tunica dartos of the scrotum: report of a case

Corticosteroids are effective in bringing about a clinical remission in patients with ulcerative colitis. However, in severely relapsed cases, corticosteroids are not always effective even when a high dosage is administered. In addition, the long-term use of corticosteroids often causes serious side effects. Therefore, an alternative treatment for active ulcerative colitis is necessary in order to avoid these clinical problems. In the present pilot study, the efficacy of leukocytapheresis using a centrifugal procedure was evaluated for corticosteroid-resistant, active ulcerative colitis. Fourteen patients with corticosteroid-resistant severely active ulcerative colitis were treated by leukocytapheresis. Thirteen patients (92.9%) achieved clinical remission within 4 weeks after the apheresis, and remained in remission for 8 months on average without any additional corticosteroid therapy. In the remaining patient, in whom remission was not induced, a total colectomy was performed immediately after the fourth course of leukocytapheresis. No significant side effects were noticed throughout the therapy. Both colonoscopic and histological examinations confirmed the beneficial effect of this procedure in terms of the reduction of severe inflammation of the affected colon. We found that the expression of two adhesion molecules, L-selectin and VLA4a, on the surface of peripheral leukocytes was decreased after this new therapy.     

Cavernous hemangioma of the umbilical cord

We report the case of a cavernous hemangioma with a recently developed hematoma of the umbilical cord. Because of a threatening intrauterine asphyxia an operative vaginal delivery was performed followed by pulmonary disturbance of adaptation and anemia with transfusion. Possible complications are discussed both in terms of the case-history and literature.     

Cavernous lymphangioma of mediastinum--a case report

A 2-year-old girl with mediastinal cavernous lymphangioma was successfully treated in 1991. She had a cough and an abnormal shadow in the right mediastinum was shown on her chest X-ray. The tumor, which spread from the right upper mediastinum to the pre-aorta, was demonstrated on CT and MRI. On August 8, 1991, the operation was performed through the right thoracotomy. The tumor was located in the right-upper and middle mediastinum and involved N. phrenics and vagus, but didn't invade and was completely resected. It was 4.2 x 3.4 x 3.2 cm in size and the cut surface of the tumor had an appearance consisting of the soft solid tissue, but containing partial cystic spaces. Histological diagnosis was cavernous lymphangioma. The mediastinal cavernous lymphangioma has been reported in only 6 cases in the Japanese medical literature.     

Accessory scrotum with penoscrotal transposition and retrocerebellar arachnoid cyst: a case report

Colonization of areas of intestinal metaplasia by Helicobacter pylori is rare and there is only one report in the literature of this organism colonizing areas of intestinal metaplasia in the antral mucosa. We report two more cases where H. pylori were seen in the gastric pits with intestinal metaplastic changes in the antral biopsy specimens.     

Malignant mesenchymoma in the scrotum. A case report

A 67-year-old man visited our hospital with the chief complaint of painless swelling of the left scrotal content. An elastic hard mass was palpable in the left scrotum. Resection of the tumor, including the left scrotal skin, was performed. The tumor originated from the scrotal wall and did not communicate with the testis, the epididymis or spermatic cord. Histologically, the tumor was diagnosed as a malignant mesenchymoma composed of liposarcoma, chondrosacoma and osteosarcoma. Malignant mesenchymoma is very rare, especially in the scrotum. Our case that originated from the scrotal wall is the first one reported in Japan.     

Bifid scrotum, perineal hamartoma and high imperforate anus: a case report

This is a case report of a newborn patient with imperforate anus, urethro-colonic fistula, perianal hamartoma, and bifid scrotum. Successful staged repair of these anomalies is described together with review of the embriology related to the case.     

Hemobilia caused by a giant benign hemangioma of the liver: report of a case

We report herein the extremely unusual case of a 39-year-old woman in whom a giant cavernous hemangioma caused hemobilia. Cavernous hemangioma is the most common benign neoplasm of the liver and rarely causes any clinical symptoms or signs, while hemobilia usually occurs secondary to accidental operative or iatrogenic trauma, vascular disease, inflammatory disorders, gallstones, or tumors of the liver. Although invasive or malignant hepatic tumors often result in a communication between the biliary tract and the blood vessels, only one case of hemobilia caused by a benign cavernous hemangioma has ever been reported, but with no details about the patient. Our patient presented to a local hospital with severe melena as the initial main symptom, where ligation of the right hepatic artery was performed. This failed to relieve her symptoms, and she was subsequently referred to our department where a right hepatectomy was performed. Histopathological examination revealed no malignancy combined with the tumor; however, the hemangioma was exposed to the bile duct in segment VIII, which was presumably the cause of the hemobilia. This patient remains in good health almost 6 years after her operation. To the best of our knowledge this is the first case report of hemobilia caused by a cavernous hemangioma, and is accompanied by a detailed analysis.     

Hemifacial spasm caused by a hemangioma at the geniculate ganglion: case report

OBJECTIVE AND IMPORTANCE: Hemifacial spasm is rarely caused by facial nerve lesions in the temporal bone. Intratemporal facial nerve hemangiomas may initially present as facial spasm. CLINICAL PRESENTATION: A 30-year-old woman developed right hemifacial spasm. Physicians observed slight weakness on the right side of her face, in addition to the hemifacial spasm, but routine radiological examinations did not detect any abnormal findings along the course of the facial nerve. Although the patient underwent neurovascular decompression, the spasm persisted postoperatively. Two years after surgery, the right facial palsy progressed. Concurrently, the hemifacial spasm diminished. High-resolution computed tomography demonstrated a small mass lesion expanding the cortex of the right petrosal bone involving the geniculate ganglion of the facial nerve. INTERVENTION: The patient underwent a second craniotomy through a subtemporal extradural route, and the tumor was completely removed. A pathological examination demonstrated a cavernous hemangioma. CONCLUSION: Routine radiological examinations may fail to detect small intratemporal facial nerve hemangiomas, particularly at the geniculate ganglion. Therefore, when physicians encounter atypical facial spasm, the intratemporal portion of the facial nerve should be carefully examined using high-resolution computed tomography.     

Bilateral horizontal gaze palsy with pontine cavernous hemangioma: a case report

Epilepsy is a common condition. In most cases, treatment with medications is satisfactory. When antiepileptic drugs fail to control the seizures, further evaluation may be warranted. EEG-video monitoring can allow a definitive diagnosis of epileptic seizures to be made by differentiating epileptic events from paroxysmal symptoms that can be mistaken for seizures (i.e., pseudoseizures). In addition, it usually allows one to accurately diagnose the seizure type, facilitating selection of the best possible treatment. Occasionally, surgery may be a therapeutic option in patients with intractable seizures.     

Intraparenchymatous vascular tumors of the testicle: report of a new case of cavernous hemangioma

The occurrence of a vascular tumour at the intraparenchymatous testicular level is a fact little reported in the literature. Searching for such events, 19 cases were found all of which showed benign clinical behaviour. The most commonly seen histological pattern is cavernous haemangioma (11 patients). Mean age at presentation is 19 years old and the most usual pre-operative diagnosis, germinal cell neoplasia. Since there are no specific ultrasound patterns that may allow to differentiate benign from malignant masses, inguinal orchiectomy is the choice treatment in this type of lesions. Furthermore, the case of a 44-year old patient with hypoechogenic solid mass in left testis who consulted for sporadic episodes of long-standing scrotal pain is presented. After radical exeresis of the gonad, the histological analysis showed existence of testicular cavernous haemangioma.     

Sonodynamic changes after transcatheter arterial embolization in a vaginal hemangioma: case report

A 36-year-old pregnant woman with a rapidly growing hemangioma in the vagina was treated by transcatheter arterial embolization after delivery. Blood flow characteristics within the tumor were evaluated using transvaginal color Doppler ultrasound both before and after the embolization. The vascular resistance in the tumor vessels within the vaginal hemangioma was observed to be significantly decreased; the tumor reduced in volume following this non-surgical treatment.
