This is the fifth metaplastic papillary tumor of the fallopian tube identified in a postpartum tubal ligation. Light microscopic studies demonstrate a mucinous metaplasia. The ultrastructure of this unusual papillary epithelial proliferation reveals abundant filaments with condensations. The tumor has not recurred during 4 years of follow-up.
The authors evaluated 774 endometrial biopsies that were performed for infertility. Complications arose in 3.6%. Lag of more than 2 days was found in 19%; luteal phase defect (LPD) was diagnosed in 5.7%. Most of the incidence of LPD can be predicted from chance occurrence. There was no association between abnormal biopsies and basal body temperature patterns, or between pathology, pregnancy outcome, and treatment. Exceptions included women with multiple spontaneous abortions and patients treated with clomiphene citrate (CC). An endometrial biopsy was performed in a pregnancy cycle in 4.0%, with an abortion rate not significantly different from the total study group. The authors conclude that an endometrial biopsy is relatively safe; however, the diagnostic and therapeutic consequences are limited. Endometrial biopsies may be useful only if performed in cases of habitual abortion or ovulation induction with CC.

Although Henoch-Schonlein purpura is known for its acute vasculitic manifestations, chronic residual problems, other than nephritis, are uncommon. A case report of late ileal stricture following Henoch-Schonlein purpura is presented, noting associated findings suggestive of a primary enteropathy which delayed timely surgical management.
A 15-year-old girl evidenced a slowly progressive central nervous system degenerative disorder. The illness had begun and progressed between ages 1 and 12 years, with ataxia, spasticity, choreoathetosis, early-onset seizures (which later ceased), and mild retardation. At age 13 she had developed rapidly progressive generalized weakness and atrophy, indicating peripheral nervous system involvement. Laboratory investigation revealed the presence of sea-blue histiocytes in the bone marrow without evidence of a disorder of sphingolipid metabolism or neuronal ceroid lipofuscinosis. Muscle biopsy showed large- and small-group atrophy, and sural nerve biopsy demonstrated axonal degeneration. This patient's illness appears to be a hitherto undescribed form of "sea-blue histiocytosis" associated with neurological dysfunction in children.
Malignant fibrous histiocytoma has been reported as a primary renal tumor in 7 cases, of which 4 had relevant clinical histories and followup. We report an additional case noting, as others have, the similarity in clinical presentation with renal cell carcinoma. Despite a radical operation this tumor often manifests local recurrence with subsequent distant metastases.
Gingival metastases from non-oral malignancies are very uncommon. The case is presented of a man with rectal adenocarcinoma, whose first clinical evidence of metastatic disease was a gingival metastasis. Although the prognosis of patients with gingival metastases is felt to be poor, prompt initiation of appropriate therapy may afford significant palliation. A 20-year literature review of uncommon metastatic sites for rectal adenocarcinoma and non-oral malignancies which can metastasize to gingiva is briefly presented. Gingival metastasis should be included in the differential diagnosis of a gingival lesion in a patient with prior or current malignancy.
