Lipohyperplasia of ileocecal valve, causing recurrent intussusception.

Lipohyperplasia of the ileocecal valve is a fairly common entity that occasionally behaves as an intestinal tumor, causing obstruction, sometimes with intussusception, or bleeding, which may be acute or chronic. Most often occurring in middle-aged or elderly women, it may be mistaken clinically and radiologically for carcinoma or other neoplasms. Its differentiation is best made by endoscopy, confirmed if possible by biopsy. Differentiation is important, as the treatment is a limited ileal and cecal resection, instead of a blind hemicolectomy. A recent study suggests possible associations with other medical conditions. We describe the clinical and pathological findings of this entity in a patient who had recurrent bouts of intussusception over a period of seven years, causing gastrointestinal symptoms and a palpable mass, eventually requiring surgical treatment.

Silicone synovitis.

Silicone synovitis around a broken silicone elastomer finger joint implant was first described by Aptekar et al in 1974. More recently, it has become apparent that synovitis can result from abraded particles from intact prostheses, which can cause severe damage to adjacent bones and joints. Early recognition of this complication is important because prompt removal of the implant may be necessary to arrest a progressive, destructive process.

Silicone lymphadenopathy and synovitis. Complications of silicone elastomer finger joint prostheses.

We report two complications of silicone elastomer finger joint prostheses. In one patient, the prostheses broke, with silicone particles present in synovium ("detritic synovitis"). In another patient, silicone particles were found in an axillary lymph node five years after insertion of prostheses in the ipsilateral hand (prostheses were intact at the time). Microscopically, silicone particles in synovium and lymph node were identical to particles abraded from a new prosthesis.
