In order to better define the frequency and patterns of metastasis to the female genital tract, all cases of nonhematopoietic metastases to the adnexa, uterus, vagina, and vulva encountered in patients treated at Barnes Hospital between 1950 and 1981 were reviewed. Three hundred twenty‐five metastatic cancers from 269 patients were recovered. One hundred forty‐nine cases were from extragenital primaries; the remaining tumors were intragenital metastases. Ovary and vagina were the most frequent metastatic sites for both extragenital and genital primaries. The majority of the extragenital metastases were adenocarcinomas from the gastrointestinal tract, but a variety of other primaries did spread, on occasion, to the genital tract. Twenty‐seven percent of the metastases presented as possible primary gynecologic lesions, and 75% of these tumors had an extragenital origin. It is shown that despite certain trends in the distribution of metastases, all sites in the female genital tract are at risk for the occurrence of metastases.

The authors presented the cases of two children with inflammatory myofibroblastic (IMF) tumor and reviewed the literature to facilitate the preoperative recognition, delineate the clinical features, and describe the natural history of this entity. The first child had IMF tumor arising from the mesentery of the small intestine. He presented with an abdominal mass associated with severe inflammatory response manifested by fever, impaired growth, thrombocytosis, and microcytic, hypochromic anemia. After surgical resection, his fever resolved and his growth rate and the laboratory abnormalities normalized. Five months after initial diagnosis, the fever, anemia, and thrombocytosis recurred along with two tumors arising from the omentum and the abdominal soft tissue. After the second surgery, he remains free of recurrent disease for 30 months. The second child presented with a lung mass that was radiologically indistinguishable from pulmonary sequestration. After surgical resection, she remains free of recurrent disease for 18 months. IMF tumor should be considered in any solid tumor that occurs in association with a chronic inflammatory response. IMF tumor should also be considered in the differential diagnosis of pulmonary sequestration.

Carcinoma metastatic to the spleen is found at autopsy in 6% to 13% of patients who die of cancer, yet clinical symptoms referable to splenic metastases are unusual. Two cases of breast carcinoma metastatic to the spleen discovered incidentally at therapeutic splenectomy for idiopathic thrombocytopenic purpura are described. On gross examination, the spleens were mildly enlarged with a homogeneous congested cut surface; rare 0.2-cm white nodules were present in one case. Microscopic examination revealed large, poorly cohesive cells that diffusely involved both the red and white pulp. Histochemical, immunohistochemical, and ultrastructural analyses confirmed the epithelial nature of the cellular infiltrate. These cases show that idiopathic thrombocytopenic purpura may herald the presence of diffuse splenic metastases when metastatic disease is not otherwise clinically suspected. The lack of a discrete tumor mass in the spleen in such cases may make the diagnosis of metastatic carcinoma a challenge both clinically and pathologically. Immunohistochemical and electron microscopic examinations are useful to establish the appropriate diagnosis in such cases.
