Multiple leiomyoma of the scrotum. A case report

A variety of neoplasms derived from mesechymal elements may arise on the tunica dartos, the tunica albuginea or, more rarely, within the testis or the epididymis. The authors report a case of leiomyoma of the scrotum in a 33-year-old man. This rare and benign tumour is localized in the tunica dartos in 8% of cases. The positive diagnosis is based on histological examination after conservative treatment by local excision which gives excellent results.     

Sonographic findings in leiomyoma of postorchiectomy scrotum

Leiomyomas of the scrotum are unusual testicular masses and a case report reviewing the ultrasonographic findings of this entity comprises this report. The ultrasonographic characteristics of leiomyoma have not been reported previously. The purpose of this case report is to discuss the findings of ultrasound in evaluation of leiomyoma in the area of the scrotum.     

Pedunculated scrotal mass: leiomyoma of scrotum.

Scrotal leiomyomas of the tunica dartos are extremely rare and usually misdiagnosed. A case of a pedunculated mass observed expectantly over thirty years demonstrates the benign oncologic natural history of this lesion despite its capability for substantial growth. Only limited local surgical management of such lesions is indicated.     

A case of retrovesical leiomyoma

We herein report a rare case of leiomyoma in the retroperitoneal space posterior to the urinary bladder. A 61-year-old man came to our department complaining of lower abdominal discomfort. Abdominal and pelvic computed tomographic scan revealed a retrovesical solid tumor on the cranial side to the left seminal vesicle. Diagnostic imaging suggested that the retrovesical tumor was a benign tumor such as leiomyoma or fibroma, and he underwent simple resection of this retrovesical tumor via reroperitoneal approach. Histopathological diagnosis was well compatible with image diagnosis of leiomyoma. He has been followed up for 6 months without recurrence.     

A case of pulmonary leiomyoma

We report a case of pulmonary parenchymal leiomyoma. The patient was a 35- year-old female with a tumor in anterobasal segment of the left lung. Enucleation was performed. The tumor was ball type and 2 cm in diameter, showing smooth and reddish brown cut surface. Microscopic and electron microscopic histology proved it to be leiomyoma.     

A case of renal leiomyoma

A case of renal leiomyoma in a 35-year-old female is presented. Since 1948, fifteen cases including our own case of renal leiomyoma, have been reported in the Japanese literature. They were discovered either from clinical symptoms or incidentally by on image diagnostic study. Some diagnostic and therapeutic problems are discussed.     

A case of fibrous pseudotumor in the scrotum

A 65-year-old man presented with a complaint of the swelling of his right scrotum. Ultrasonogram indicated a tumor in the right scrotum, but it was not apparent whether the tumor arose from the right testis or not. Right high orchiectomy was performed due to the suspicion of malignancy. The tumor arose from the right epididymis and spermatic cord. Histological examination revealed that the tumor was a fibrous pseudotumor in the scrotum.     

A bizarre foreign body in the appendix:A case report

Foreign bodies are rare causes of appendicitis and,in most cases,ingested foreign bodies pass through the alimentary tract asymptomatically.However,ingested foreign bodies may sometimes remain silent within the appendix for many years without an inflammatory response.Despite the fact that cases of foreign-bodyinduced appendicitis have been documented,sharp and pointed objects are more likely to cause perforations and abscesses,and present more rapidly after ingestion.Various materials,such as needles and drill bits,as well as organic matter,such as seeds,have been implicated as causes of acute appendicitis.Clinical presentation can vary from hours to years.Blunt foreign bodies are more likely to remain dormant for longer periods and cause appendicitis through obstruction of the appendiceal lumen.We herein describe a patient presenting with a foreign body in his appendix which had been swallowed 15 years previously.The contrast between the large size of the foreign body,the long clinical history without symptoms and the total absence of any histological inflammation was notable.We suggest that an elective laparoscopic appendectomy should be offered to such patients as a possible management option.     

A case of leiomyoma of the intermediate bronchus

Leiomyoma of the trachea and bronchus is a rare tumor. Only 45 cases have been reported in the Japanese literature. We report here a case of leiomyoma of the intermediate bronchus which was successfully operated on. A 45-year-old man suffered from a repeated episode of pneumonia in the right lower lobe. Bronchoscopy revealed a polypoid mass on the intermediate bronchus. The diagnosis of leiomyoma was made by bronchoscopic biopsy. Sleeve resection of the intermediate bronchus including the tumor and end-to-end anastomosis was performed. His postoperative course was uneventful and bronchoscopic findings showed clear healing of the anastomotic site. The resected specimen contained a tumor with smooth surface having protrusion into the bronchial lumen with 6 x 5 x 4 mm in size. The final pathological diagnosis was leiomyoma of the intermediate bronchus with no evidence of malignancy.     

A case of giant leiomyoma of the esophagus

A 34-year-old man was admitted to our hospital because of a tumor shadow in the posterior mediastinum. Leiomyoma of the esophagus was suggested by the findings of CT, esophagography, and esophagoscopy. He underwent thoracotomy. The operative procedure was enucleation of the tumor. The histological examination confirmed it to be a leiomyoma. The postoperative course was uneventful, and the passage of the esophagus was good. He was discharged 36 days after the operation.     

A case of pure leiomyoma of the prostate

A case of pure leiomyoma of the prostate is reported. This disease is very rare and only 10 cases could be collected from the Japanese literature. Our case is the 11th case of this disease in Japan. A 48-year-old man was admitted to our hospital because of urinary retention. Retrograde urethrocystogram showed evidence of protrusion of the left lobe of the prostate. Excretory urogram revealed bilateral hydronephrosis and voiding cystogram revealed VUR on left ureter. Transurethral biopsy suggested benign prostatic tumor. Open resection of the tumor was performed. Histologically, the specimen removed was pure leiomyoma of the prostate. After operative treatment, disturbance of urination and hydronephrosis disappeared.     

A case of primary leiomyoma of the ureter

This report describes a case of primary leiomyoma of the ureter in which only partial ureterectomy was performed based on the diagnosis of benign tumor by rapid diagnosis using a frozen section during the operation. Surgical treatment was opted for upon diagnosis of a submucosal tumor of the right ureter, with no abnormal findings in the ureteral mucosa by ureteroscopy. To our knowledge, nine cases have been reported worldwide since 1955, suggesting this case to be the 10th.     

A case of leiomyoma of the spermatic cord

A 46-year-old man visited our clinic with the chief complaint of indolent swelling of the left scrotal contents. An elastic hard and fist-sized mass with negative transillumination was palpable in left scrotum, but testis and epididymis were not discriminated. Left high orchiectomy was performed. Tumor was 90 X 55 mm in size and the testis and epididymis at the lower pole of the tumor were intact. Histological diagnosis was leiomyoma and we diagnosed leiomyoma of the spermatic cord. To our knowledge, this is the 5th case reported in Japan.
