A unique case of transient spontaneous regression complicated with tumor lysis syndrome of T-cell lymphoblastic lymphoma in HIV-infected patient without antiretroviral therapy.

Spontaneous regression in high-grade non-Hodgkin lymphoma is rare. Herein, the authors report the case of a 26-year-old asymptomatic HIV-infected patient presenting with bleeding per gum after a dental extraction. Initially, a complete blood count showed lymphoblasts and thrombocytopenia. Laboratory investigations were compatible with acute tumor lysis syndrome. Without any steroid or chemotherapy, both clinical and laboratory abnormalities were spontaneously returned to normal limits. However, three weeks later he developed generalized lymphadenopathy. A submandibular gland biopsy revealed to be T-cell lymphoblastic lymphoma. This was followed by the second episode of spontaneous tumor lysis syndrome and spontaneous regression of lymphadenopathy again. At this time, he was treated with cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP) with whole brain irradiation. During seven months of chemotherapy, the physical examination and blood chemistry were normal. Unfortunately, after seven courses of CHOP, the disease rapidly progressed and ultimately lead to his death.

Overt disseminated intravascular coagulation in obstetric patients.

OBJECTIVE: To determine the incidence, etiology and outcome of treatment in obstetric patients complicated by overt disseminated intravascular coagulation (DIC). MATERIAL AND METHOD: Medical records of 25 obstetric patients with a diagnosis of DIC in Songklanagarind University Hospital from January 1993 to December 2005 were reviewed RESULTS: The incidence of overt DIC was I per 1,355 deliveries. Median maternal age was 30 years (range 17-44 years). Median duration of hospital stay was 10 days (range 0-32 days). The main associated conditions included abruptio placentae in 6 patients (24%), pregnancy-induced hypertension (PIH) in 5 (20%), amniotic fluid embolism in 4 (16%), acute fatty liver of pregnancy (AFLP) in 4 (16%), and HELLP syndrome in 3 (12%). A definite diagnosis ofDIC was made in 8 patients (32%) with a median DIC score of 6 (range 5-7) and the remainder were clinically diagnosed with incomplete work-up. All patients received blood component replacement. Cesarean section was performed in 10 patients (40%) and hysterectomy in 9 patients (36%). Six patients died, giving a case mortality rate of 24%. Three were associated with amniotic fluid embolism and one of each with fulminant hepatitis, ALFP and HELLP syndrome. Thirteen of 24 fetuses (54%) died, most related to abruptio placentae (6/6, 100%), PIH (4/5, 80%), and amniotic fluid embolism (2/4, 50%). CONCLUSION: Various pregnancy-related conditions will predispose to DIC development. Early diagnosis with prompt treatment, including a quick decision for surgical intervention, and eradication of predisposing conditions would minimize maternal morbidity and mortality.
