Spinal epidural lipomatosis (SEL) is a rare condition characterized by overgrowth of normal adipose tissue in the extradural space within the spinal canal that can lead to significant spinal cord compression. It is most commonly reported in patients receiving chronic glucocorticoid therapy. Other causes can include obesity and hypercortisolism. Occasionally, idiopathic SEL will occur in patient...

Lipomas are the most common type of soft tissue benign tumor with a prevalence of 2.1 per 1000 people (1). They generally occur in adult patients between the ages of 40 and 60 years as solitary lesions. In some cases, however, there can be multiple lipomas involving several members of a family or associated with other systemic manifestations as in some syndromes. Cases of iatrogenic lipomatosis...

Renal replacement lipomatosis (RRL) is a relatively uncommon entity, although misdiagnosis mainly with xanthogranulomatous pyelonephritis (XGP) due to lack of awareness by urologists, radiologists, and pathologists may be responsible for underreporting1,2. We illustrate a case of RRL that was initially misdiagnosed as XGP, and compare it with a classic case of XGP, underscoring the similarities...

Massive adipose tissue depositions in the abdomen and thorax sufficient to interfere with respiration developed in a patient with multiple medical problems. Biopsy of adipose tissue identified human adenovirus 36 (Adv 36) DNA. Adv 36 causes adipogenesis in animals and humans. Development of massive lipomatosis may be caused by Adv 36.

Benign symmetrical lipomatosis is a rare condition characterized by symmetrical deposition of adipose tissue in the neck, sholder, and arm area. About 200 cases have been reported in the medical literature, primarily from Europe. A 54-year-old man presented with masses in the neck, shoulders and arms. He underwent surgical treatment based on cosmetic reasons. Histopathologically, subcutaneous t...
