Granular cell ameloblastoma of jaw. A report of rare case and brief review of literature.

Ameloblastoma is an epithelial odontogenic tumour of the jaw and exhibits diverse microscopic patterns which occurs either singly or in combination with other patterns. The rare granular cell variant is seen in combination usually with follicular or plexiform subtypes. The reported case reveals the microscopic patterns characteristic of granular cell variant only, which is uncommon. The tumour was excised and no recurrence has been observed after nineteen months of surgery.

Pathogenesis of peptic ulcer in rheumatoid arthritis.

To assess the pathogenesis of the gastro-duodenal mucosal lesions in rheumatoid arthritis, 36 patients, consisting of 23 (group I) receiving non-steroidal anti-inflammatory drugs (NSAIDs) and 13 (group II) on alternative forms of treatment, were examined by fibreoptic upper gastrointestinal endoscopy. Ten (43%) of 23 patients receiving NSAIDs showed mucosal damage in the form of erosions or a definite ulcer crater, compared to only one (8%) of 13 in group II (p less than 0.05). There was no correlation between the duration of illness and the incidence of mucosal lesions. These findings indicate that the high incidence of gastroduodenal mucosal abnormalities seen in rheumatoid arthritis is related to the use of NSAIDs and not to the underlying disease process.

Pure red cell aplasia with rheumatoid arthritis. A case report and review of literature.

Pure red cell aplasia (PRCA) is an extremely uncommon treatable manifestation of rheumatoid arthritis. Here we describe a case of long standing rheumatoid arthritis with severe refractory anaemia, which was proven to be due to PRCA.
