Cytologic appearance of pigmented villonodular synovitis. A case report

BACKGROUND: Pigmented villonodular synovitis (PVNS) is a benign neoplasm of large joints. It may follow a locally aggressive course. The cytologic features of this neoplasm have not been characterized fully. CASE: A 70-year-old male presented with a lump in the left ankle joint. The histopathologic diagnosis was pigmented villonodular synovitis. Review of the cytologic smears revealed clusters of round and ovoid, bland-looking cells along with siderophages and binucleated and multinucleated giant cells. CONCLUSION: When interpreted in the clinical context, fine needle aspiration cytology may render a correct preoperative diagnosis of pigmented villonodular synovitis.     

Three structures associated with the nucleolus in male rat germinal cells: round body, coiled body, and "nubecula" and general presence of round body at male meiosis.

In addition to chromosomes and nucleoli, three structures, i.e., round body, coiled body, and nubecula, are encountered in the nucleus during the meiotic prophase in male rats. These structures have been examined by electron microscopy in random and serial sections. The round body is a finely fibrillar, proteinaceous structure closely associated with the granular component of a nucleolus in rat spermatocytes and young spermatids. A similar structure has been observed in man, the monkey Macaca mulatta, the gastropod Achatina fulica, and the insect Locusta migratoria. Together with evidence from the literature, these results support the view that the round body is of general occurrence in the male meiocytes of eukaryotes and may, therefore, play a role in meiosis. The coiled body is a group of electron-dense elements called "coils", which average 35 nm in width, except after mid-pachytene when their size almost doubles. The coils are composed of 2-nm-wide filaments and 8 to 10-nm-wide granules, both of which are ribonucleoprotein. The coiled bodies are interpreted to be groups of "spliceosomes", that is, structures containing heterogeneous RNA and small nuclear RNA. A remarkable feature of the coiled body is its temporary disappearance at early pachytene and its reappearance at late pachytene, possibly due to drastic changes in the turnover rate of its component RNAs. The nubecula is a newly identified nuclear inclusion, composed of weakly staining threads loosely organized into a 560 nm-wide spheroid. It has been observed only in early pachytene nuclei.

The appearance pattern of tooth germs in the round crucian carp,Carassius auratus grandoculis

Cyprinid fishes generally replace their teeth alternately and cephalad. The larvae ofCarassius auratus grandoculis also replace their teeth alternately and cephalad, in a pattern of 4-2-3-1-. However, adults ofCarassius species replace their teeth from anterior to posterior, in a pattern of 1-2-3-4-1-. So I analyzed the appearance pattern of tooth germs in larvae and juveniles inCarassius auratus grandoculis. At stage 5 of the post-larval period, developmental difference is made between both sides. In the pharyngeal dentition on one side developing poorly, the anterior tooth on the fifth replacement wave, tooth₄[An2] appeared later than the central teeth on following replacement wave, tooth₅[Pol]. Moreover, the anterior tooth on the seventh replacement wave, tooth₆[An2], appeared later than the central teeth on the following replacement wave, tooth₇[Pol], on both sides. The reverse of tooth germ appearance between anterior teeth and central teeth makes a change of replacement pattern from 4-2-3-1-4- to 1-2-3-4-1-. The change of replacement pattern is caused by the confusion of tooth germs of anterior teeth on both sides.Mylopharyngodon piceus andCyprinus carpio make a change of replacement patterns in the early juvenile period, too. This change of replacement pattern may be a specialized character among the subfamily Cyprininae.     

Fine needle aspiration appearance of extragastrointestinal stromal tumor. A case report

BACKGROUND: Gastrointestinal stromal tumors (GISTs) rarely develop outside the digestive tract and in the soft tissues of abdomen and retroperitoneum. Such tumors are designated extra-GISTs (EGISTs). Cytologic and immunocytochemical features of a case of EGIST are reported. CASE: A 54-year-old woman presented with a peritoneal mass, diameter 22 cm, adherent to the omentum and without a connection to the digestive tract. Fine needle aspiration biopsy (FNAB) of the excised tumor showed high cellularity in two patterns: monotonous spindle cells were intermingled with a mildly atypical epithelioid component. Immunocytochemistry performed on cytospins revealed reactivity for c-kit (CD117), CD34 and smooth muscle actin and negativity for S-100. The findings were concordant with a histologic diagnosis of EGIST. CONCLUSION: EGISTs are infrequent neoplasms and can be diagnosed in FNAB samples. The clinical/radiologic setting must be considered together with the cytologic features. Immunocytochemistry is a clue to the diagnosis when it detects c-kit reactivity.
