Abstract:
Purpose To investigate the clinicopathlogical characteristics, diagnosis and differential diagnosis of ovarian small cell car-cinoma hypercalcemic type ( OSCCHT) associated with acute renal dysfunction. Methods A case of OSCCHT associated with acute renal dysfunction was reported. The clinical and pathologic data, treatment and pathological examinations were analyzed and the related literatures were reviewed. Results A 29-year-olds women was presented to hospital with inappetence and significant weight loss for 2 months. The laboratory examination showed abnormal renal function, and pelvic cavity mass, possibly coming from adnexa of the uterus was seen by radiography. Serum levels showed significantly increased serum calcium with acute renal dysfunction. An emergency opera-tion was performed just after renal function partially recovered by 2 times hemodialysis. During surgery, right ovary tumor with a size of 12 cm × 10 cm × 10 cm was inspected. Microscopically, the tumor cells were arranged in a diffuse solid pattern, mutiple nodules were separated by fibrous tissue. some small folliculars and pseudoglandular cavities with acidophilia secretion within nodules could been ob-served. Tumor cells were medium to large with eosinophilic cytoplasm, round or oval vesicular nucleus, increased karyoplasmic ratio and pathologic mitosis. Immunohistochemistry revealed that the tumor cells expressed EMA, CKpan, C-erbB-2 ( +) , CA125 ( focal+) and Ki-67 proliferation index was about 60%, while ER, PR, Syn, CgA, PTH, Inhibin, CD99, AFP, PLAP, CD30 and CD20 were not expressed. Conclusion Ovarian small cell carcinoma hypercalcemic type with acute renal dysfunction is a very rare with a rapidly progressive and highly malignant tumor. The final diagnosis mainly lies on clinical information ( hypercalcaemia) , morphology and immunohistochemistry, combined with electron microscopy and molecular biological detection when necessary.
