Metastatic melanoma is often difficult to diagnose morphologically. However, the prognostic and therapeutic decision in cases of metastatic melanoma depends upon the morphologic documentation of the metastatic disease, which may rapidly and accurately be done by cytologic methods such as aspiration cytology of clinically suspicious lesion. Cytological features of 12 metastatic melanoma are described. Evaluation for melanin pigment, background composition, cytoplasmic vacuoles, intranuclear inclusions, bi or multinucleated cells, eccentric nuclei, nucleoli, and degree of cellular cohesion were made. the presence of melanin pigment, prominent nucleoli, intranuclear cytoplasmic inclusions, lack of cell cohesion, and eccentric nuclei are the important and useful cytologic features in the diagnosis of metastatic melanoma. Bior multinucleated cells, cytoplasmic vacuoles, and bloody background are also frequently found in smears from metastatic melanoma.

Glomus tumors are neoplasms that are composed of modified smooth muscle cells of the glomus body. Here, we report a case of multiple glomus tumors of the ankle that showed various histologic types, including the solid type (glomus tumor proper) and angiomatous type (glomangioma). The tumor cells observed in this case also showed prominent intranuclear inclusions, which has not yet been reported in glomus tumors. Ultrastructural examination demonstrated that the nuclear inclusions were not true inclusion bodies but were intranuclear cytoplasmic pseudoinclusions formed by cytoplasmic invaginations that formed as a result of the deep and complex nuclear contours.

Here we report a case of the classical inclusion body myositis. The muscle pathology in a 61-year-old male patient with slowly progressive proximal muscle weakness and atrophy revealed basophilic rimmed vacuoles on light microscope and intracytoplasmic filamentous inclusions with membranous whorls through electron microscope. He did not respond to steroid therapy.

In 1971 inclusion body myositis was reported by Yunis and Samaha. This disease is similar with chronic multiple myositis clinically. Pathologically, inclusion body myositis is characterized by intracytoplasmic vacuole with degenerating fibers and accompanied with inclusion body in internal nucleus and cytoplasm. Since then 240 cases of inclusion body myositis have been reported in the world including 3 cases in Korea. A 27 years-old lady had inclusion body myositis, which show slowly progressive muscular weakness. We confirmed this with clinical symptom, muscle biopsy, and electrophysiologic study. We report the typical manifestation of inclusion body myositis in a 27 years-old lady with the brief review of literature.

Myrmecia, a type of palmoplantar warts, are induced by human papilloma virus type 1(HPV1). They occur not only on the palms and soles, but also on the lateral aspects and tips of fingers and toes. Histologically, it is characterized by abundant eosinophilic inclusion bodies associated with HPV1 E4 gene products. We report two cases of myrmecia developing on the dorsum of finger.

BACKGROUND: The cytopathic effects of cytomegalovirus (CMV) infection have been well described since the virus was first reported; however, the morphology of CMV infection has not been clearly studied. We examined the difference in detailed cytologic findings in bronchial washing cytology between liquid-based and conventionally prepared smears. METHODS: Bronchial washing cytology was processed using either the conventional preparation (CP) or liquid-based preparation (LBP). Sixty-nine cells with typical cytopathic effects of CMV infection were detected on CP slides and 18 cells on LBP slides. Using the image analyzer, area, circumference, major axis, and minor axis of the cytoplasm, nucleus, and intranuclear inclusion were measured in singly scattered CMV-infected cells, and histiocytes were used as a control. RESULTS: The mean cytoplasmic area of CMV-infected cells was 1.47 times larger than that of histiocytes in CP and 2.92 times larger in LBP (p<.05). The mean nuclear area of CMV-infected cells was 2.61 times larger than that of histiocytes in CP and 4.25 times larger in LBP (p<.05). The nucleus to cytoplasm ratio and intranuclear inclusion to cytoplasm ratio of the mean area, circumference, major axis, and minor axis in CP were larger than those in LBP (p<.05). CONCLUSIONS: The sizes of cytoplasm, nucleus, and intranuclear inclusion were larger in LBP than in CP, indicating that CMV-infected cells are easily detectable in LBP. However, the nucleus-to-cytoplasm ratio was larger in CP, suggesting that differentiation from malignancy or regenerative atypia requires caution in CP.

Inclusion bodies containing glycogen granules are characteristic feature of infected cells with Chlamydia trachomatis(C. trachomatis). In this study, we investigated the serial changes of the glycogen granules in a rabbit conjunctival epithelial cells co-cultivated with C. trachomatis.The epithelial cells isolated grom conjunctiva of rabbit were initially cultured for 3 weeks. After the cells had attained confluency, they were infected with C. trachomatis serotype D. After co-cultivation for 24, 48 and 96 hours, electronmicroscopic study was performed.After co-cultivation for 24 hours, a few glycogen granules were observed within the premature inclusion body containing some elementary bodies and reticulate bodies. After 48 hours of co-cultivation, typical inclusion bodies were observed and numerous electron-dense glycogen granules predominated around reticulate bodies. After 96 hours of co-cultivation, scattered glycogen granules were observed in granular pattern within the expanding inclusion occupying the bulk of the host cell cytoplasm.These results suggest that glycogen granules are closely related to the developmental cycle of the C. trachomatis and they may be an energy source for active multiplication of the reticulate bodies.

The clinical significance of cytoplasmic inclusions(CPI) in synovial fluid(SF) examination was evaluated. We examined SF specimens collected from major rheumatology clinics in the Philadelphia area during the period of January to December 1995. Among 759 patients in the initial study group, 419 cases with established diagnoses and full synovial analyses were included. Their diagnoses and SF analysis results including leukocyte counts, differential counts and wet preparations were collected and analysed. Ninety seven of the 419 SF specimens were found to have CPI. CPI were found in SF from almost all rheumatic diseases. They were most likely to be found in inflammatory arthropathy including rheumatoid arthritis(RA, 46%), juvenile rheumatoid arthritis(JRA, 78%) and psoriatic arthritis(55%). On the contrary, CPI were least common in crystal-induced arthropathy among the inflammatory arthropathy. CPI were found 8 out of 98 gout cases(8%) and 2 among 53 calcium pyrophosphate dihydrate(CPPD) deposition disease(4%). In noninflammatory arthropathy, CPI were found in only 6 cases(6%) out of the 103 osteoarthritis(OA). In RA cases with non-inflammatory SF, 4 of the 20 SF(20%) had CPI while only 6% of OA SF had CPI. OA SF with CPI were all noninflammatory SF. In summary, CPI were a common finding on SF examination. CPI were more likely to be found in inflammatory arthropathy than noninflammatory. Among inflammatory arthropathy, CPI can favor non-crystal arthropathy than crystal arthropathy. Awareness of the presence of CPI is suggested as an addendum to routine SF analysis. Renewed investigation of the several types of CPI may add further to the understanding of joint disease.

A 63-year-old man presented with a 1.5-year history of progressive personality changes. Clinical evaluations revealed severe frontal dysfunction and bilateral frontal atrophy/glucose hypometabolism. He was diagnosed as probable behavioral variant frontotemporal dementia. He continued to decline, and died at the age of 66. At autopsy, numerous tau-positive gilial threads and coiled bodies were observed in the white matter. Tau-positive astrocytic plaques and neuronal cytoplasmic inclusions were also seen in cerebral cortices, which were compatible with corticobasal degeneration.
