 Abstract

- Uterine adenomyoma is a neoplasm that is composed of endometrial glands and smooth muscle, and this is found in the uterine corpus; however, the glandular component is occasionally of mucin-secreting endocervical type. We describe here a case of uterine adenomyoma of the endocervical type, and this presented in a 38-year-old pregnant woman.

Abstract
PDF
- Eosinophilic cytoplasmic globules may be seen in a variety of neoplastic and nonneoplastic conditions and are most often associated with alpha-1-antitrypsin deficiency, several pathologic liver conditions and yolk sac tumors. A few cases of eosinophilic cytoplasmic globules in renal cell carcinoma have been reported but there has only been one report of papillary type. We report another case of papillary renal cell carcinoma with eosinophilic cytoplasmic globules, which is similar to a Mallory body but with different properties.

Abstract
PDF
- We present a case of recurrent follicular lymphoma with an extensive plasma cell component involving infra-auricular lymph nodes in a 64 year-old woman. Immunohistochemical staining showed a strongly positive reaction of the follicles with CD20, bcl-2, bcl-6, CD10 and CD21 on the first biopsy specimen. The intrafollicular and interfollicular plasma cells showed monoclonality for IgG heavy chain and lambda light chain. The histological and immunohistochemical findings in the recurrent tumor were identical with those of the original. Discussion is focused on the importance of the differential diagnosis between reactive lymphoid hyperplasia and other lymphomas having plasmacytic differentiation.

Abstract
PDF
- A micropapillary variant of urothelial carcinoma (MPC) is a distinct entity with an aggressive clinical course. It has a micropapillary configuration resembling that of ovarian papillary serous carcinoma. Its cytologic features have rarely been reported. We report a case of MPC detected by urine cytology. A woman aged 93 years presented with a chief complaint of macroscopic hematuria. Cytology of her voided urine showed clusters of malignant cells in a micropapillary configuration. Each tumor cell had a vacuolated cytoplasm, a high nuclear:cytoplasmic ratio, and irregular hyperchromatic nuclei. An ureteroscopic examination revealed exophytic sessile papillary masses extending from the left lateral wall to the anterolateral wall of the urinary bladder. A transurethral resection of the tumor was carried out. The tumor was characterized by delicate papillae with a thin, well-developed fibrovascular stromal core and numerous secondary micropapillae lined with small cuboidal cells containing uniform low- to intermediate-grade nuclei and occasional intracytoplasmic mucinous inclusions. These tumor cells infiltrated the muscle layers of the bladder, and lymphatic tumor emboli were frequently seen. Recognizing that the presence of MPC components in urinary cytology is important for distinguishing this lesion from low-grade papillary lesions and high-grade urothelial carcinomas can result in early detection and earlier treatment for an improved treatment outcome.

Abstract
PDF
- Liposclerosing myxofibrous tumor (LSMFT) is a benign fibro-osseous lesion that is characterized by a complex mixture of histologic elements, including its fibrous dysplasia-like features and its lipoma, myxofibroma, xanthoma and pseudo-Paget's bone patterns. However, this lesion is considered by some researchers as a variant of fibrous dysplasia or as the non-specific end result of degenerative change, while it is considered by others as a definite clinicopathologic entity. Here, we report on a case of LSMFT occurring in tibia, which is a very uncommon location for this tumor, and we review the related literatures. The case presented here shares features with those described for LSMFT, except for the location of this tumor. We believe that more studies on a larger scale that compare LSMFT with other benign bone lesions, including fibrous dysplasia, are required to clarify the origin and behavior of this lesion.
