A 54-year-old woman referred with abdominal swelling. Imaging studies revealed a huge mass localized in pelvis and lower abdomen and grade 1-2 left renal hydronephrosis. Preoperative Ca-125 was 798 U/ml.
In exploratory laparotomy there was a 16 cm mass adherent to lateral abdominal wall and intestines. Adhesiolysis and de-bulking surgery were performed including bilateral pelvic, para-aortic lymphadenectomy, appendectomy and omentectomy. Left ureter was found to be dilated because of the infiltration of distal part by the tumor, so distal ureteral resection and neoureterocystostomy were performed. Final Selleckchem GSK1904529A pathology revealed borderline serous ovarian tumor with mural nodules which were consisted of SLMNs, multiple and sharply demarcated from the adjacent tumor, and sarcomatous nodules showing infiltrative appearance in metastatic regions. SCH 900776 molecular weight Mural nodules showed a positive reaction for vimentin and SMA but were negative for cytokeratin and also necrosis, hemorrhage, and 10-15 mitoses in 10 high power fields were noted. She had postoperative chemotherapy and follow-up is going on without metastases in her first year.
The existence of sarcomatous nodules combined with the SLMN necessitates a careful histologic analysis for treatment and the determination of prognosis. However, too few
cases of mixed type mural nodules have been published to warrant a conclusion regarding their prognosis.”
“The outer most layer of the skin, the epidermis, is attached to the dermis via
a sheet of extracellular matrix proteins termed the basement membrane zone (BMZ). In the intact skin, adhesion of the keratinocytes in the basal layer of the epidermis to the BMZ is facilitated primarily by hemidesmosomes which associate with the keratin cytoskeleton. Cultured keratinocytes do not assemble bona fide hemidesmosomes although hemidesmosome protein clusters (stable anchoring contacts) are found along the substrate-attached surface of the cells and towards the leading edge of keratinocytes repopulating scratch wounds. Actin cytoskeleton-associated matrix adhesion devices termed focal contacts are not thought to play an important role in the adhesion of keratinocytes to the BMZ in intact skin but are prominent in cultured keratinocytes where they are believed to regulate Lonafarnib cell migration. We review the molecular components, functions, dynamics and cross-talk of hemidesmosomes and focal contacts in keratinocytes. In addition, we briefly describe what is known about their role in autoimmune and genetic blistering diseases of the skin. We also discuss recent publications which indicate, contrary to expectation, that certain focal contact proteins retard keratinocyte migration while hemidesmosomal proteins regulate directed keratinocyte motility during wound healing.
