A series of 90 endometrial biopsies and curettings originally diagnosed as chronic endometritis were reviewed and histological findings of plasma cells, lymphoid infiltrate, stromal necrosis, acute inflammation, lymphoid follicles, and epithelial atypia were correlated with the demonstration of chlamydial antigens by the immunoperoxidase technique. Chlamydial antigens were localized within endometrial epithelial cells in four cases. Although these four cases represented only 4% of the total number, chlamydial immunoperoxidase positivity was best discriminated by the severity of the inflammation and the presence of an acute inflammatory infiltrate. Among cases of severe endometritis 22% were chlamydia-positive, and in those cases with an associated acute inflammatory infiltrate, 57% were positive. A high index of suspicion of chlamydial infection should exist when severe endometritis is diagnosed in patients with clinical histories of post-abortal state, pelvic inflammatory disease, secondary infertility or menometrorrhagia, and chronic pelvic pain.

Non-Hodgkin's lymphoma involving the ovaries is unusual and may cause confusion for the clinician since its presentation might resemble other, much more frequent tumors. Malignant lymphoid cells may occur in the ovary either as a primary neoplasm or as a secondary manifestation of a disseminated occult or known disease. The most common presenting signs or symptoms of malignant lymphomas involving the ovaries are abdominal or pelvic pain or mass. We present here a unique case of non-Hodgkin's lymphoma involving the ovaries presenting as advanced ovarian cancer with a pelvic mass, pleural effusion, and marked elevation of CA-125.

Seventy-five malignant mesotheliomas of the peritoneum in women were reviewed to highlight their morphologic spectrum. The patients ranged from 17 to 92 (mean, 47.4) years of age. The clinical presentation was usually abdominal or pelvic pain, abdominal swelling (sometimes due to ascites), or a pelvic mass. On microscopic examination, the majority of the tumors had only an epithelial morphology, but 4 were biphasic and 1 was sarcomatoid. The most common epithelial patterns were tubular and papillary (which often coexisted), but 5 tumors were purely diffuse; 2 had cells with abundant glassy eosinophilic cytoplasm (so-called deciduoid mesothelioma). The cells in the tubular and papillary patterns were generally cuboidal with scant to moderate amounts of eosinophilic cytoplasm. Nuclear atypia was usually only mild, although a minority of cases had moderate or even, occasionally, severe atypia. Many tumors had foci that, viewed in isolation, resembled so-called well-differentiated papillary mesothelioma, and accordingly that diagnosis should be made cautiously. Unusual features were lymphoid follicles (13 cases), striking myxoid stroma (5 cases), prominent foamy histiocytes (5 cases), and a striking vascular proliferation (1 case). The varied morphology of peritoneal malignant mesotheliomas may raise a broad differential diagnosis, but in most cases the resemblance to other tumors is limited. Histochemistry, immunohistochemistry, and electron microscopy may provide important aid, particularly when tissue is limited, but should be needed only occasionally.

Herein we report the case of a 41-year-old woman who presented with pelvic pain. Magnetic Resonance Imaging exhibited a single pelvic mass, measuring 50mm long axis, alongside the right iliac vessels. Histological examination of the excision specimen showed a lymphoid tumor with features of localized Castleman disease, hyaline vascular type. Moreover we identified multiple interfollicular dark clusters, composed of cells morphologically resembling cortical thymocytes. Their immunophenotype was consistent with an intermediate stage of T-cell differentiation, with the expression of CD3, CD4, CD8, TdT, CD1a, CD99, CD2, CD5, CD7 and CD10, with 40% Ki67. After integration of clinical and molecular data, the retained diagnosis was an indolent T-cell lymphoblastic proliferation associated with hyaline vascular localized Castleman disease. The clinical course confirmed the indolent nature of the proliferation, despite a late local recurrence at 7 years of the initial diagnosis, without histological modification, due to an incomplete initial resection surgery.
