Purpose  Radiotherapy treatment planning of extended volume typically necessitates the utilization of multiple field isocenters and abutting dosimetrically matched fields in order to enable coverage beyond the field size limits. A common example includes total lymphoid irradiation (TLI) treatments, which are conventionally planned using dosimetric matching of the mantle, para-aortic/spleen, and...

Report of a Case. A 61-year-old man developed cutaneous melanoma in the right preauricular skin. It was managed by surgical resections, skin grafts, irradiation, chemotherapy, and laser for local recurrences and cervical node metastasis. After 18 months, he was referred for progressive ipsilateral conjunctival pigmentation. Examination disclosed cutaneous pigmentation and scarring in the right ...

introduction: kikuchi-fujimoto disease or histocytic necrotizing lymphadenitis is a rare, benign, self-limited condition characterized by constitutional symptoms, lymphadenopathy, and skin lesions and often affects young adult females.the etiology is unknown although viruses and autoimmune mechanisms has been suggested. diagnosis is fundamentally based on the affected lymph node biopsy.the pati...

Adult C57BL/6 mice exposed to fractionated irradiation or inoculated with the radiation leukemia virus (RadLV), develop high incidence (80-100%) of lymphatic leukemias within 3-6 mo. RadLV-induced lymphomas can elicit cytotoxic responses in vitro in lymphocytes of preimmunized syngeneic mice, a reaction that is dependent on the expression of membrane-associated viral antigenicity. As soon as 5 ...

A reliable, inexpensive experimental counterpart of peripheral lymphedema has been notoriously difficult to reproduce thereby stifling basic and clinical research into this frustrating clinical condition. Accordingly, in 45 adult Wistar-Fuzzy rats, we attempted to produce sustained hindlimb lymphedema by either groin nodal/lymphatic microsurgical ablation (S) (guided by visual blue dye lymphogr...

Lewis rats given total lymphoid irradiation (TLI) accepted bone marrow allografts from AgB-incompatible donors. The chimeras showed no clinical signs of graft-versus-host disease. Skin allografts from the marrow donor strain survived for more than 150 days on the chimeras. However, third-party skin grafts were rejected promptly. Although heart allografts survived more than 300 days in Lewis rec...

associations of some hematological and lymphatic diseases with sex and abo and rh blood groups were studied in 2579 patients, compared with a control group of 126332 individuals, by the use of clinical as well as laboratory findings, in tehran. highly significant increase of male/female ratio is shown in acute myelogenous leukemia, acute lymphocytic leukemia, chronic lymphocytic leukemia, aplas...
