RESUMO
The Sister Mary Joseph's nodule is a periumbilical metastatic tumor originating from advanced metastatic intra-abdominal and intrapelvic malignancies. It is an inconspicuous and uncommon clinical sign, which not only shows the presence of visceral malignancy but also reveals the poor prognosis of these malignancies. The majority of cases originate from gastrointestinal or ovarian cancer. We present a case of an 80-year-old woman with an umbilical nodule, which was the sole presenting symptom of advanced signet ring cell carcinoma of the stomach with generalized peritoneal carcinomatosis. There are very few cases of gastric signet ring cell adenocarcinoma presenting as a SMJN, a fact rather striking as signet ring cell gastric carcinoma has an increased frequency of peritoneal dissemination and carcinomatosis of the peritoneum.

Pilomatricoma is a benign skin tumor derived from the hair follicle, usually located in the head and neck and presenting in the first two decades of life. Clinically it most commonly presents as a hard, mobile, well circumscribed nodule. Microscopically it is characterized by the presence of shadow cells and may show calcification, while extensive ossification is rare. Surgical removal is the treatment of choice, as the recurrence rate is very low. We present a rare case of late regressive pilomatricoma of the arm in a 33 year old female which presented with extensive ossification.

We reviewed 100 cemented Endo-model rotating-hinge (Waldemar Link GMBH & Co, Hamburg, Germany) total knee replacements in 80 patients with a mean age of 70 years (56 to 85) at a mean post-operative follow-up of 11 years (7 to 15). Good or excellent results were seen in 91% of knees and survival at 15 years was 96.1%. There were two deep infections, one dislocation and one supracondylar fracture. There were no peri-operative deaths and there was no loosening, malalignment, migration or wear. We consider this prosthesis to be ideally suited for the replacement of the deformed knee when the use of an unconstrained design may be questionable.

The thoracic kyphosis angles of 16 normal individuals, 10 patients with Scheuermann's disease and 11 with adolescent idiopathic scoliosis were measured both radiographically and from Integrated Shape Imaging System (ISIS) scans obtained by surface stereophotogrammetry. There was a high correlation between the two measures. The method of kyphosis measurement from ISIS scans was then used for 30 patients with adolescent idiopathic scoliosis who underwent corrective surgery. A significant reduction in thoracic kyphosis was observed postoperatively. In another group of 28 patients managed conservatively by bracing, some hypokyphosis developed after treatment. However, we found no association between hypokyphosis and curve progression.
