The nonfunctioning adrenal tumor is a rare disease. These tumors are difficult to diagnose because they usually remain asymptomatic. Recently computerized tomography (CT) scan has been used because it shows retroperitoneal anatomic details. Three cases of nonfunctioning adrenal tumors are reported. All were found by CT scan. The diagnostic methods and treatment are discussed. The most useful radiologic study of nonfunctioning adrenal tumor is CT scan and the early surgical approach remains the mainstay of treatment.

The records of 50 patients with primary carcinoma of the fallopian tube referred to postoperative radiotherapy at the Radium Centre of the Finsen Institute, Copenhagen, were reviewed. The most common symptoms were postmenopausal bleeding, vaginal watery discharge and abdominal pain. In 86% of the patients a palpable pelvic tumor was found at preoperative gynecologic examination. Disease was localized to the pelvis (stage I and stage II) in nearly all patients (92%). Ten patients were given radiotherapy as vaginal radium twice combined with deep X-ray to the pelvis, and 38 patients were given radiotherapy as high-voltage irradiation to the pelvis only. The overall survival at 5 years was 50.9%. Still, the role of radiotherapy in the control of this rare disease remains to be established. To obtain a better prognosis for this disease, international cooperative prospective studies are proposed.

Melanoma involving the nasal and paranasal sinus mucosa is a rare disease that is difficult to treat and generally has a poor prognosis. Data on 17 patients treated at the UCLA Medical Center during the period 1970 to 1985 were reviewed in a retrospective manner. The five-year disease-free survival was 25% (3/12). Surgery, with or without radiation therapy, is the mode of treatment to control disease in most patients. Treatment failures, which include both local recurrence and distant metastases, may occur many years after initial therapy. We found a correlation between the thickness of tumor and the clinical outcome.

Liposarcoma of the mediastinum is a rare disease. A 59 year old woman was seen with the complaint of dizziness. A chest radiogram taken during the course of investigation for hypertension revealed a large mass shadow 24 X 18.5 X 12 cm located in the anterior mediastinum. The tumor of the mediastinum was diagnosed as a benign lipoma when it was first resected, but subsequently proved to be a liposarcoma when it re-appeared 2 years and 10 month later. Based on the WHO classification, the mixed type of liposarcoma was diagnosed. The salient and pathological features of mediastinal liposarcoma are reviewed and compared with those nine cases reported in Japan and fifty in North America and European countries. Treatment by simple enucleation or shelling out of the tumor should be discouraged, since this seems to be the main cause of local recurrence. Surgical wide en bloc excision is the treatment of choice.

Unilateral adrenal tuberculosis is a very rare disease. A 66-year-old woman presented with epigastric discomfort and general fatigue. Abdominal CT scan revealed a homogeneous mass shadow in the right adrenal region. Findings of physical examination were normal except that the patient was obese. Hormonal data were in normal range. Adrenal scintiscanning demonstrated no RI uptake in the right adrenal gland. Right adrenalectomy was performed under the diagnosis of nonfunctioning tumor of the right adrenal gland. Histopathological examination, however, revealed typical tuberculosis with Langhans' type of giant cells and infiltrated lymphocytes. Of 322, 148 autopsies performed during the twelve years between 1970 and 1981 in Japan, 228 cases of adrenal tuberculosis were recognized. Furthermore, only 18 cases had tuberculous regions in the adrenal gland alone.

Retroperitoneal neurinoma is a rare disease, although retroperitoneal tumor is rather common. A 40-year-old man without any clinical symptoms was admitted to our hospital for a medical examination. Ultrasonogram demonstrated a cystic mass over the right kidney. This cystic mass was suggested to be a right adrenal tumor by CT scan and angiogram. All of the laboratory data including endocrinological data were within the normal limits. Under the diagnosis of right non-functioning adrenal tumor, an operation was performed through a right lumbal incision. A round and tennis ball sized tumor with a fibrous capsule was identified and freed from the right kidney and the right adrenal gland, and the tumor was extirpated uneventfully. The surgical specimen was 9.5 X 8.0 X 6.5 cm in size, 260 g in weight, and the histological diagnosis was neurinoma (Antoni-B type).

Laryngeal lymphangioma is extremely rare. We have been able to find only seventeen cases reported in world literature. We recently, treated a patient suffering from laryngeal lymphangioma in our department. The female patient, aged 36, complained of hoarseness for several months. Indirect laryngoscopy revealed a growth on her right false vocal cord. Under general anesthesia, tracheostomy and laryngofissure were performed for removal of this neoplasm. The tumor was microscopically diagnosed as lymphangioma. The symptoms disappeared after surgery and there has been no recurrence. The pertinent literature on this rare disease is reviewed.

The brown bowel syndrome (BBS) is a rare disease characterized by malabsorption and accumulation of lipofuscin in the smooth muscle cells of the muscularis externa of the small intestine. Recently, we incidentally observed a case of BBS in a colon operated on because of a neoplasm. Our ultrastructural investigation, which demonstrated changes in the mitochondria, further supports the significance of mitochondrial damage in BBS.

Non-germinal cell tumor of the testis is a rare disease, and vascular tumor of the testis is a still rarer disease. Herein, a case of cavernous hemangioma of the testis is reported. A 75-year-old man consulted our department with the complaint of a painless left intrascrotal tumor. Laboratory findings revealed slight leukocytopenia and thrombocytopenia of unknown origin. In chest X-ray, a diffuse reticular shadow was shown and it was considered due to pulmonary fibrosis, but, alpha-fetoprotein and CEA were normal. Left radical orchiectomy was performed under spinal anesthesia. The tumor existed under the tunica albuginea, and the cutting surface of the tumor was brown and irregular. There were hemorrhagic portions in some places. The left epididymis and the left spermatic cord were normal. Histologically, the tumor was diagnosed as cavernous hemangioma. The vascular tumor of the testis is a very rare disease, and only 17 cases have been reported including this case. This case was the 7th case of cavernous hemangioma of the testis, and the first case in Japan. This patient died of respiratory failure due to pulmonary fibrosis and pneumonia. In the autopsy, there was no abnormal finding that was considered to be related to the cavernous hemangioma of the testis.

Risk has different meanings even within the confines of trophoblastic disease. One unquantifiable risk for patients is treatment by physicians or surgeons with limited knowledge of this rare disease and its modern management. Risk can be immediate at the time of presentation because the disease has sometimes progressed to a life-threatening state before the diagnosis is established. Special problems at that time need consideration on the basis of which organs are involved. Placental-site trophoblastic disease presents distinctive features and requires different management. A major long-term risk is drug resistance, and a high proportion of late treatment failures in choriocarcinoma arise from inappropriate therapy at an early stage in treatment. "Prognostic," or "risk," scoring identifies the propensity of a tumor to become resistant to chemotherapy and enables treatment to be planned from the outset to minimize that risk.
