The case of a seventy-one-year-old woman with leiomyosarcoma of the kidney capsule is presented. Despite lack of invasion into surrounding tissues and few mitoses, the tumor recurred thirteen months after nephrectomy. A full subjective response and an almost complete objective regression lasting eight months were achieved using a short course of combination chemotherapy. The literature on leiomyosarcoma of the kidney is reviewed.

An aberrant adrenal, which is a supplementary to the normal adrenal, was found in the apex of hernial sacs in ten out of 350 operated children. This tissue contains adrenal cortex, which tends to atrophy and disappear during childhood, but uncommonly may persist into adult life. Rarely it may secrete abnormally or undergo neoplastic changes. The embryological development is discussed, and the literature briefly reviewed.
Five cases of cervical pregnancy collected over an 8-year period (1971--1978) are analyzed. The incidence of cervical pregnancy at this institution is 1:7040 pregnancies. All cases were diagnosed prior to 12 weeks' gestation, and conservative treatment was instituted in each case. Etiology, criteria, definition, and clinical and pathologic signs are discussed. Several unusual features are emphasized, particularly conservative treatment and the use of ultrasound as a diagnostic aid.

We examined the central nervous system of a 67-year-old man who showed symptoms of lathyrism after being imprisoned at age 35 and fed on a diet of chick peas, Lathyrus sativus. The most obvious changes were loss of axons and myelin in the pyramidal tract in the lumbar spinal cord. These alterations correlated with spastic paraparesis. Other changes at the same level were a mild degree of degeneration of anterior horn cells. Pallor of Goll's tracts and axonal swelling in Goll's nuclei were also observed. A few examples of senile plaques and neurofibrillary tangles were observed in Ammon's horn.

Splenomegaly is an unusual finding in Crohn's disease and can be persistent or transient. In three febrile patients it was so prominent that the diagnosis of lymphoma was considered. In two additional patients the splenomegaly was an incidental finding. It is probably a nonspecific response to the basic disease in most cases, or occasionally a response to the chronic liver disease that can occur in inflammatory bowel disease.
This is a case report of a 29-year-old male with a chondroblastoma of the os calcis successfully treated by almost total resection of the tuber calcanei without sacrifice insertion of the tendon achilles.

A case of cortriatriatum, which is not included in three types of Loeffler's classification, is reported, and a complete description of the anatomy and pathology of the case is given. A successful surgical repair of this malformation is possible; therefore the importance of its recognition is emphasized. The clinical manifestations and the different aetiopathogenic theories are reviewed.
A woman suffering from recurrent attacks of abdominal pain was found at operation to have a fibroma of the cecum. The clinical, operative and pathologic findings are described. The medical literature was reviewed and the lesion was found to be uncommon. The importance of specific histologic stains to distinguish the true fibroma from other spindle-cell tumors is stressed.
