Endometriosis mimics general surgical disease.

Endometriosis is rarely encountered by the general surgeon but may on occasion mimic general surgical disease. Although usually diagnosed easily because of cyclic symptoms and typical physical findings, six atypical cases are presented. These cases were diagnosed as appendicitis (2), subcutaneous mass (2), pelvic wall malignancy, and lower gastrointestinal hemorrhage. Diagnosis was ultimately made by laparotomy or excisional biopsy in five cases and by fine needle aspiration in one. Resection of the lesion, if feasible, is often curative. If resection is not feasible, therapy depends on the severity of the symptoms, and the patient's desire for fertility. Recognition of the typical appearance of an endometrioma may avoid mistaking it for cancer.

Multiple synchronous primary intra-abdominal neoplasms.

Multiple synchronous primary intra-abdominal neoplasms involving more than one organ system are rare, particularly if the appendix is involved. We report a patient with synchronous primary lesions in the colon, appendix, and the kidney. We also discuss the incidence of this entity with respect to sex and age, the organs most often involved in instances of multiple primary lesions, and review the criteria for differentiation of synchronous versus metachronous lesions.

CARCINOID TUMOR OF THE VERMIFORM APPENDIX WITH DISTANT METASTASIS.

Metastatic carcinoid tumors of the appendix are probably not as rare as is commonly thought. In five of thirteen cases diagnosed at the Stanford-Palo Alto Hospital, there was microscopic evidence of lymphatic invasion. Metastasis to regional nodes was demonstrated in two of the five. These two cases bring the total number reported in the medical literature to 31. One of the patients was a 14-year-old girl. The youngest patient previously cited with metastasis from carcinoid tumor of the appendix was 16 years of age. We believe that all carcinoid tumors, regardless of location, are malignant lesions and urge careful pathologic study for evidence of lymphatic invasion. When such invasion is present, removal of regional nodes by right hemicolectomy seems indicated.
