Barrett's epithelium is a columnar, possibly premalignant, metaplasia of the oesophagus. To study the pattern of epithelial renewal in this disorder, we localised the lower oesophageal sphincter by manometry in 12 patients with known Barrett's epithelium, obtained multiple suction biopsies above the sphincter, and organ cultured the biopsies over 3H-TdR-containing medium to label proliferating ...

Rosai-Dorfman disease is a rare, benign histiocytic proliferative disorder that usually affects the lymph nodes. Although extranodal involvement has been reported in diverse sites, manifestation in the cardiovascular system is extremely rare. Specifically, cardiac involvement in Rosai-Dorfman disease is an extraordinarily infrequent event. We describe a case of a 36-year-old female who presente...

Bizarre parosteal osteochondromatous proliferation (BPOP) is a benign disorder within a spectrum of reactive proliferative processes of tubular bones, particularly the phalanges of the fingers or toes. The cause is unknown, and it is difficult to distinguish BPOP from a bone or soft tissue tumor. The radiographic and magnetic resonance imaging manifestations of reported BPOP cases are mostly no...

Castleman's disease (CD) is a rare lympho-proliferative disorder due to faulty immune regulation resulting in proliferation of lymphatic tissue. The vascular supply to these lesions have been reported to arise from the bronchial, internal mammary and the intercostal arteries. We report a case of hemoptysis secondary to intrathoracic CD with vascular supply arising from the left inferior phrenic...

Rosai-Dorfman disease is a rare histiocytic proliferative disorder that commonly presents with a massive lymphadenopathy and a variety of constitutional symptoms. Severe hemolytic anemia is an infrequent complication of this disease. Although the etiology of the condition is unknown, infectious agents including viruses have been implicated. We describe a 2-year-old female child who presented wi...

We share our experience with serial PET/CT imaging on a patient with extranodal Rosai-Dorfman disease (RDD) with hepatopancreatic involvement. RDD is a benign proliferative disorder of histiocytes mainly involving the lymph nodes. It typically presents with fever and painless cervical lymphadenopathy in young adults and less than half of RDS cases demonstrate extranodal involvement. RDD involve...

We present a family in which at least four persons have evidence of an inherited disorder comprising a variable spastic paraplegia, bilateral sensorineural deafness, intellectual retardation, and a progressive nephropathy. Focal segmental proliferative lesions with sclerosis suggestive of mesangial IgA nephropathy (Berger's disease) were found on renal renal biopsy in two affected persons. The ...

Rosai-Dorfman Disease (RDD) or sinus histiocytosis with massive lymhadenopathy (SHML) is a rare, benign proliferative disorder of histiocytes characterized by painless bilateral cervical lymph node enlargement though extranodal disease involving skin, respiratory system, central nervous system (CNS) etc may been in > two third of cases (1-3). With lack of widespread awareness about this entity,...

Castleman's disease is a rare nonclonal proliferative disorder of the lymph nodes with an unknown etiology. Common locations of Castleman's disease are mediastinum, neck, axilla, and abdomen. Castleman's disease of a peripancreatic location masquerading as pancreatic neoplasm is an even rarer entity. On search of published data, we came across about 17 cases published on peripancreatic Castlema...
