Studying a large series of malignant lymphoma is important to increasing our understanding of this disease. Based on the World Health Organization classification system, 1983 cases of lymphoma at Siriraj Hospital were classified as either non-Hodgkin lymphoma (NHL) (92.1%) or Hodgkin lymphoma (HL) (7.9%). The NHL cases were 75% B cell type and 25% T cell(More)
Diagnostic criteria in myeloma have not been completely standardized or tested for accuracy; furthermore, marrow findings of prognostic value have not been clearly identified. We studied 176 patients with myeloma to determine the relative value of marrow differential, tissue sections, and immunohistology singly or in concert in the diagnosis of myeloma and(More)
Extranodal NK/T-cell lymphoma (ENKTL), nasal type, may be of NK or T-cell origin; however, the proportion of T-ENKTLs and whether they are of αβ or γδ type remains uncertain. To elucidate the cell of origin and detailed phenotype of ENKTL and assess any clinicopathologic associations, 67 cases of ENKTL from Thailand were investigated, together with 5 γδ(More)
BACKGROUND According to the World Health Organization classification (2001), intravascular large B-cell lymphoma (IVLBCL) is characterized by the presence of lymphoma cells only in the lumina of small vessels. It has not been proven whether IVLBCL is a specific clinicopathologic entity. Intravascular large B-cell lymphoma and other intravascular(More)
BACKGROUND Analysis of malignant lymphoma in a single institution at different periods of time can determine the changing status of the disease in the region. METHODS To compare with the large series of 1095 lymphoma cases reported between 1957-1971 at Siriraj Hospital, the largest hospital in Thailand, a similar study was performed through(More)
Vascular permeability, thrombocytopenia, liver pathology, complement activation, and altered hemostasis accompanying a febrile disease are the hallmarks of the dengue hemorrhagic fever/dengue shock syndrome, a major arthropod-borne viral disease that causes significant morbidity and mortality throughout tropical countries. We studied tissues from 13(More)
Clofazimine-induced crystal-storing histiocytosis is a rare but well-recognized condition in the literature. Besides the common reddish discoloration of the skin, clofazimine produces gastrointestinal disturbances-sometimes severe abdominal pain, prompting exploratory laparotomy, because pathologic and radiologic findings can produce diagnostic difficulties(More)
Clinicopathologic information of gastrointestinal (GI) lymphoma in Southeast Asia is lacking. A retrospective analysis of 120 cases of GI lymphoma in Thailand diagnosed at Siriraj Hospital based on WHO classification was performed. All were non-Hodgkin lymphoma (NHL). The peak age was in the sixth and seventh decades; a slight male preponderance was(More)
Myeloma is a common and well-studied hematopoietic neoplasm with an impressive spectrum of clinical, laboratory, and histological findings. To enhance our understanding of the diversity of myeloma, including its earliest forms, the clinical and pathological findings in 145 cases of myeloma were documented and analyzed. Our analysis indicated that myeloma(More)
Primary cutaneous, extranodal natural killer/T-cell lymphoma, nasal type (PC-ENKTL), is a rare Epstein-Barr virus (EBV)-associated neoplasm with poorly defined clinicopathologic features. We performed a multinational retrospective study of PC-ENKTL and CD56-positive EBV-negative peripheral T-cell lymphoma (PC-CD56+PTCL) in Asia in an attempt to elucidate(More)
